description: Google Cloud credentials setup and management for Google Drive/Gmail integration

# Google Cloud Credentials Setup
## How Credentials Were Located
### Discovery Process
1. **User mentioned Gmail MCP was already configured**
- Checked Claude Desktop config at `/Users/wz/.claude.json`
- Found Gmail MCP server configuration:
```json
"@gongrzhe/server-gmail-autoauth-mcp": {
"env": {
"GMAIL_OAUTH_PATH": "/Users/wz/Desktop/OAuth2/gcp-oauth.keys.json",
"GMAIL_CREDENTIALS_PATH": "/Users/wz/.gmail-mcp/credentials.json"
}
}
```
2. **Located OAuth Credentials**
- Path: `/Users/wz/Desktop/OAuth2/gcp-oauth.keys.json`
- Size: 412 bytes
- Created: Sep 24 16:12
- Contains: OAuth 2.0 client credentials from Google Cloud Console
3. **Located Stored Token**
- Path: `/Users/wz/.gmail-mcp/credentials.json`
- Size: 552 bytes
- Created: Sep 26 03:44
- Contains: Authenticated user token (access + refresh tokens)
## File Locations
```bash
# OAuth Client Credentials (from Google Cloud Console)
/Users/wz/Desktop/OAuth2/gcp-oauth.keys.json
# Authenticated User Token (after OAuth flow)
/Users/wz/.gmail-mcp/credentials.json
# Token for Drive API (auto-created by gdrive_sync.py)
/tmp/token.pickle
```
## Using Credentials for Google Drive
### Setup Script
```python
# /tmp/gdrive_sync.py uses these credentials
# 1. Looks for credentials.json (OAuth client config)
CREDENTIALS_FILE = '/tmp/credentials.json' # Copy of gcp-oauth.keys.json
# 2. Creates/uses token.pickle (authenticated session)
TOKEN_FILE = 'token.pickle' # Created after first auth
```
### Integration Steps
1. **Copy OAuth credentials to working directory:**
```bash
cp /Users/wz/Desktop/OAuth2/gcp-oauth.keys.json /tmp/credentials.json
```
2. **First-time authentication (creates token.pickle):**
```bash
cd /tmp
python3 gdrive_sync.py /path/to/file.md
# Opens browser → Login to Google → Grant permissions
# Creates token.pickle for future use
```
3. **Subsequent uses (automatic):**
```bash
python3 gdrive_sync.py /path/to/file.md
# Uses existing token.pickle, no browser needed
```
## API Scopes
### Gmail MCP Scopes
```
https://www.googleapis.com/auth/gmail.readonly
https://www.googleapis.com/auth/gmail.send
https://www.googleapis.com/auth/gmail.compose
```
### Drive API Scopes (used by gdrive_sync.py)
```
https://www.googleapis.com/auth/drive.file
```
**Note:** Different scopes = Different tokens needed
- Gmail token: `/Users/wz/.gmail-mcp/credentials.json`
- Drive token: `/tmp/token.pickle`
## Quick Commands
### Sync file to Google Drive
```bash
python3 /tmp/gdrive_sync.py /path/to/file.md
```
### List files in Google Drive
```bash
python3 /tmp/gdrive_sync.py list
```
### Via Flask Server (from browser)
```javascript
// Click "📤 Sync to Drive" button in editor
// Calls: POST http://localhost:8765/sync-gdrive
```
## Troubleshooting
### "credentials.json not found"
```bash
cp /Users/wz/Desktop/OAuth2/gcp-oauth.keys.json /tmp/credentials.json
```
### "Token expired"
```bash
rm /tmp/token.pickle
python3 /tmp/gdrive_sync.py /path/to/file.md
# Re-authenticates via browser
```
### "Insufficient permissions"
```bash
# Token might have wrong scopes
rm /tmp/token.pickle
# Re-auth will request correct scopes
```
## Architecture
```
User edits in Browser
↓
Flask Server (/tmp/skill-server.py)
↓
Saves to local file (/tmp/skills/SKILL.md)
↓
Calls gdrive_sync.py
↓
Uses OAuth credentials (gcp-oauth.keys.json)
↓
Google Drive API
↓
Uploads to Google Drive (Skills folder)
```
## Files Created
```
/tmp/
├── credentials.json # OAuth client config (copied)
├── token.pickle # Authenticated session
├── gdrive_sync.py # Sync script
├── skill-server.py # Flask server with /sync-gdrive endpoint
└── skill-editor-server.html # Editor with "Sync to Drive" button
```
## Success Confirmation
When working correctly, you'll see:
```
✓ Folder 'Skills' created: <folder_id>
✓ Uploaded: SKILL.md (ID: <file_id>)
```
Check Google Drive: https://drive.google.com/drive/my-drive
- Should see "Skills" folder
- Should see uploaded .md files

name: Building Artifacts
description: Suite of tools for creating elaborate, multi-component claude.ai HTML artifacts using modern frontend web technologies (React, Tailwind CSS, shadcn/ui). Artifacts are automatically saved to ~/Desktop/Artifacts directory. Use for complex artifacts requiring state management, routing, or shadcn/ui components - not for simple single-file HTML/JSX artifacts.
license: Complete terms in LICENSE.txt

# Artifacts Builder
**Stack**: React 18 + TypeScript + Vite + Tailwind CSS + shadcn/ui
## Workflow
1. Initialize: `bash scripts/init-artifact.sh <project-name>`
2. Develop in generated project
3. Bundle: `pnpm run build` (Vite bundling, see Step 3 for configuration)
4. Share bundled HTML with user
5. Test only if needed (optional)
## Artifact Types
### Type 1: Complex Interactive Applications
Multi-component applications with state management and routing. Use React stack above.
### Type 2: Interactive Primary Source Artifacts
Explorable visualizations of documentation, papers, books. Use HTML with collapsibles and structured navigation (no React).
**Reference**: `primary-sources-reference.md`
**Use for**: Technical docs, research papers, books/textbooks, historical documents
## Design Guidelines
Avoid "AI slop": no excessive centered layouts, purple gradients, uniform rounded corners, or Inter font.
## Step 1: Initialize
```bash
bash scripts/init-artifact.sh <project-name>
```
**Location**: `~/Desktop/Artifacts/` (fallback: current directory)
**Creates**:
- React + TypeScript (Vite)
- Tailwind CSS 3.4.1 + shadcn/ui theming
- Path aliases (`@/`)
- 40+ shadcn/ui components + Radix UI dependencies
- Parcel configured (.parcelrc)
- Node 18+ compatibility
## Step 2: Develop
```bash
cd ~/Desktop/Artifacts/<project-name>
```
Edit generated files. See **Common Development Tasks** for guidance.
## Step 3: Bundle
```bash
bash scripts/bundle-artifact.sh
```
**Requirement**: `index.html` in project root
**Output**: `bundle.html` - self-contained artifact with inlined JavaScript, CSS, dependencies
**Process**:
- Installs: parcel, @parcel/config-default, parcel-resolver-tspaths, html-inline
- Creates `.parcelrc` with path alias support
- Builds with Parcel (no source maps)
- Inlines all assets
### Fallback: Vite + vite-plugin-singlefile
If Parcel fails (e.g., @swc/core signature errors on macOS), use Vite:
1. **Install vite-plugin-singlefile**:
```bash
pnpm add -D vite-plugin-singlefile
```
2. **Update vite.config.ts** with complete configuration:
```typescript
import { viteSingleFile } from "vite-plugin-singlefile";
export default defineConfig({
plugins: [react(), viteSingleFile()],
resolve: {
alias: {
"@": path.resolve(__dirname, "./src"),
},
},
build: {
rollupOptions: {
output: {
inlineDynamicImports: true,
manualChunks: undefined,
},
},
cssCodeSplit: false,
},
});
```
3. **Build**:
```bash
pnpm run build
```
4. **Output**: `dist/index.html` - fully self-contained, opens directly in browser (file:// protocol)
**Critical**: The `build` configuration is **required**. Without `inlineDynamicImports: true`, `manualChunks: undefined`, and `cssCodeSplit: false`, the bundle will not work properly (JavaScript won't execute, modules won't load).
**When to use**:
- Parcel bundling fails with signature errors
- Custom inline scripts produce non-executable output
- Need reliable single-file distribution
## Step 4: Share
Share `bundle.html` (or `dist/index.html` if using Vite fallback) in conversation for user to view as artifact.
## Step 5: Testing (Optional)
Test only if requested or issues arise. Use available tools (Playwright, Puppeteer). Avoid upfront testing—adds latency.

license: Complete terms in LICENSE.txt
---
# MCP Server Development Guide
Create high-quality MCP servers that enable LLMs to effectively interact with external services. Quality is measured by how well LLMs accomplish real-world tasks using the provided tools.
---
# Process
## Phase 1: Research and Planning
### 1.1 Agent-Centric Design Principles
**Build for Workflows:** Create high-impact workflow tools, not API wrappers. Consolidate operations (e.g., `schedule_event` checks availability AND creates event).
**Optimize for Context:** Return high-signal info, not dumps. Offer "concise"/"detailed" options. Use human-readable IDs.
**Actionable Errors:** Guide agents to correct usage: "Try filter='active_only'". Make errors educational.
**Natural Subdivisions:** Tool names reflect human thinking. Group with consistent prefixes. Design around workflows.
**Evaluation-Driven:** Create realistic scenarios early. Iterate based on agent performance.
### 1.2 Study Documentation
**Load these in order:**
1. MCP Protocol: `https://modelcontextprotocol.io/llms-full.txt`
2. [📋 MCP Best Practices](./reference/mcp_best_practices.md)
3. **For Python:** `https://raw.githubusercontent.com/modelcontextprotocol/python-sdk/main/README.md` + [🐍 Python Guide](./reference/python_mcp_server.md)
4. **For Node/TypeScript:** `https://raw.githubusercontent.com/modelcontextprotocol/typescript-sdk/main/README.md` + [⚡ TypeScript Guide](./reference/node_mcp_server.md)
### 1.3 Study API Documentation
Read ALL: API reference, auth, rate limits, pagination, errors, endpoints, parameters, data models. Use web search and WebFetch.
### 1.4 Create Implementation Plan
**Tool Selection:** List valuable endpoints. Prioritize common use cases. Consider tool combinations.
**Shared Utilities:** API request patterns, pagination/filtering/formatting helpers, error handling.
**Input/Output:** Validation (Pydantic/Zod), consistent formats (JSON/Markdown), detail levels (Detailed/Concise), scale planning, character limits (25k tokens).
**Error Handling:** Graceful failures, actionable LLM-friendly messages, rate limits, timeouts, auth errors.
---
## Phase 2: Implementation
### 2.1 Set Up Project
**Python:** Single `.py` or modules. MCP SDK. Pydantic validation.
**Node/TypeScript:** Project structure (`package.json`, `tsconfig.json`). MCP SDK. Zod validation.
### 2.2 Core Infrastructure First
Create shared utilities: API helpers, error handling, response formatting (JSON/Markdown), pagination, auth/tokens.
### 2.3 Implement Tools
**Input Schema:** Pydantic/Zod with constraints (min/max, regex, ranges). Clear descriptions with examples.
**Descriptions:** Summary, purpose, parameter types with examples, return schema, usage examples, error handling with next steps.
**Logic:** Use shared utilities (DRY). Async/await for I/O. Error handling. Multiple formats (JSON/Markdown). Respect pagination. Check limits, truncate.
**Annotations:** `readOnlyHint`, `destructiveHint`, `idempotentHint`, `openWorldHint`.
### 2.4 Language-Specific Best Practices
**Python ([🐍 Guide](./reference/python_mcp_server.md)):** MCP SDK, Pydantic v2 with `model_config`, type hints, async/await, organized imports, constants.
**Node/TypeScript ([⚡ Guide](./reference/node_mcp_server.md)):** `server.registerTool`, Zod `.strict()`, strict mode, no `any`, explicit `Promise<T>`, build config.
---
## Phase 3: Review and Refine
### 3.1 Code Quality
Check: DRY (no duplication), composability (shared logic), consistency (similar formats), error handling (all calls), type safety (full coverage), documentation (comprehensive).
### 3.2 Test and Build
**Important:** MCP servers are long-running (stdio/http). Direct runs hang indefinitely.
**Safe testing:** Evaluation harness (recommended), tmux, or timeout (`timeout 5s python server.py`).
**Python:** `python -m py_compile your_server.py`. Test in tmux or via harness.
**Node/TypeScript:** `npm run build`. Verify `dist/index.js`. Test in tmux or via harness.
### 3.3 Quality Checklist
See [🐍 Python Guide](./reference/python_mcp_server.md) or [⚡ TypeScript Guide](./reference/node_mcp_server.md).
---
## Phase 4: Create Evaluations
**Load [✅ Evaluation Guide](./reference/evaluation.md) for complete guidelines.**
### 4.1 Create 10 Questions
Process: Tool inspection → content exploration (READ-ONLY) → question generation → answer verification.
### 4.2 Requirements
Each question: Independent, read-only, complex (multiple tool calls), realistic, verifiable (single answer), stable.
### 4.3 Format
```xml
<evaluation>
<qa_pair>
<question>Find discussions about AI model launches with animal codenames. One model needed a specific safety designation that uses the format ASL-X. What number X was being determined for the model named after a spotted wild cat?</question>
<answer>3</answer>
</qa_pair>
</evaluation>

# MCP Server Evaluation Guide
## Overview
This document provides guidance on creating comprehensive evaluations for MCP servers. Evaluations test whether LLMs can effectively use your MCP server to answer realistic, complex questions using only the tools provided.
---
## Quick Reference
### Evaluation Requirements
- Create 10 human-readable questions
- Questions must be READ-ONLY, INDEPENDENT, NON-DESTRUCTIVE
- Each question requires multiple tool calls (potentially dozens)
- Answers must be single, verifiable values
- Answers must be STABLE (won't change over time)
### Output Format
```xml
<evaluation>
<qa_pair>
<question>Your question here</question>
<answer>Single verifiable answer</answer>
</qa_pair>
</evaluation>
```
---
## Purpose of Evaluations
The measure of quality of an MCP server is NOT how well or comprehensively the server implements tools, but how well these implementations (input/output schemas, docstrings/descriptions, functionality) enable LLMs with no other context and access ONLY to the MCP servers to answer realistic and difficult questions.
## Evaluation Overview
Create 10 human-readable questions requiring ONLY READ-ONLY, INDEPENDENT, NON-DESTRUCTIVE, and IDEMPOTENT operations to answer. Each question should be:
- Realistic
- Clear and concise
- Unambiguous
- Complex, requiring potentially dozens of tool calls or steps
- Answerable with a single, verifiable value that you identify in advance
## Question Guidelines
### Core Requirements
1. **Questions MUST be independent**
- Each question should NOT depend on the answer to any other question
- Should not assume prior write operations from processing another question
2. **Questions MUST require ONLY NON-DESTRUCTIVE AND IDEMPOTENT tool use**
- Should not instruct or require modifying state to arrive at the correct answer
3. **Questions must be REALISTIC, CLEAR, CONCISE, and COMPLEX**
- Must require another LLM to use multiple (potentially dozens of) tools or steps to answer
### Complexity and Depth
4. **Questions must require deep exploration**
- Consider multi-hop questions requiring multiple sub-questions and sequential tool calls
- Each step should benefit from information found in previous questions
5. **Questions may require extensive paging**
- May need paging through multiple pages of results
- May require querying old data (1-2 years out-of-date) to find niche information
- The questions must be DIFFICULT
6. **Questions must require deep understanding**
- Rather than surface-level knowledge
- May pose complex ideas as True/False questions requiring evidence
- May use multiple-choice format where LLM must search different hypotheses
7. **Questions must not be solvable with straightforward keyword search**
- Do not include specific keywords from the target content
- Use synonyms, related concepts, or paraphrases
- Require multiple searches, analyzing multiple related items, extracting context, then deriving the answer
### Tool Testing
8. **Questions should stress-test tool return values**
- May elicit tools returning large JSON objects or lists, overwhelming the LLM
- Should require understanding multiple modalities of data:
- IDs and names
- Timestamps and datetimes (months, days, years, seconds)
- File IDs, names, extensions, and mimetypes
- URLs, GIDs, etc.
- Should probe the tool's ability to return all useful forms of data
9. **Questions should MOSTLY reflect real human use cases**
- The kinds of information retrieval tasks that HUMANS assisted by an LLM would care about
10. **Questions may require dozens of tool calls**
- This challenges LLMs with limited context
- Encourages MCP server tools to reduce information returned
11. **Include ambiguous questions**
- May be ambiguous OR require difficult decisions on which tools to call
- Force the LLM to potentially make mistakes or misinterpret
- Ensure that despite AMBIGUITY, there is STILL A SINGLE VERIFIABLE ANSWER
### Stability
12. **Questions must be designed so the answer DOES NOT CHANGE**
- Do not ask questions that rely on "current state" which is dynamic
- For example, do not count:
- Number of reactions to a post
- Number of replies to a thread
- Number of members in a channel
13. **DO NOT let the MCP server RESTRICT the kinds of questions you create**
- Create challenging and complex questions
- Some may not be solvable with the available MCP server tools
- Questions may require specific output formats (datetime vs. epoch time, JSON vs. MARKDOWN)
- Questions may require dozens of tool calls to complete
## Answer Guidelines
### Verification
1. **Answers must be VERIFIABLE via direct string comparison**
- If the answer can be re-written in many formats, clearly specify the output format in the QUESTION
- Examples: "Use YYYY/MM/DD.", "Respond True or False.", "Answer A, B, C, or D and nothing else."
- Answer should be a single VERIFIABLE value such as:
- User ID, user name, display name, first name, last name
- Channel ID, channel name
- Message ID, string
- URL, title
- Numerical quantity
- Timestamp, datetime
- Boolean (for True/False questions)
- Email address, phone number
- File ID, file name, file extension
- Multiple choice answer
- Answers must not require special formatting or complex, structured output
- Answer will be verified using DIRECT STRING COMPARISON
### Readability
2. **Answers should generally prefer HUMAN-READABLE formats**
- Examples: names, first name, last name, datetime, file name, message string, URL, yes/no, true/false, a/b/c/d
- Rather than opaque IDs (though IDs are acceptable)
- The VAST MAJORITY of answers should be human-readable
### Stability
3. **Answers must be STABLE/STATIONARY**
- Look at old content (e.g., conversations that have ended, projects that have launched, questions answered)
- Create QUESTIONS based on "closed" concepts that will always return the same answer
- Questions may ask to consider a fixed time window to insulate from non-stationary answers
- Rely on context UNLIKELY to change
- Example: if finding a paper name, be SPECIFIC enough so answer is not confused with papers published later
4. **Answers must be CLEAR and UNAMBIGUOUS**
- Questions must be designed so there is a single, clear answer
- Answer can be derived from using the MCP server tools
### Diversity
5. **Answers must be DIVERSE**
- Answer should be a single VERIFIABLE value in diverse modalities and formats
- User concept: user ID, user name, display name, first name, last name, email address, phone number
- Channel concept: channel ID, channel name, channel topic
- Message concept: message ID, message string, timestamp, month, day, year
6. **Answers must NOT be complex structures**
- Not a list of values
- Not a complex object
- Not a list of IDs or strings
- Not natural language text
- UNLESS the answer can be straightforwardly verified using DIRECT STRING COMPARISON
- And can be realistically reproduced
- It should be unlikely that an LLM would return the same list in any other order or format
## Evaluation Process
### Step 1: Documentation Inspection
Read the documentation of the target API to understand:
- Available endpoints and functionality
- If ambiguity exists, fetch additional information from the web
- Parallelize this step AS MUCH AS POSSIBLE
- Ensure each subagent is ONLY examining documentation from the file system or on the web
### Step 2: Tool Inspection
List the tools available in the MCP server:
- Inspect the MCP server directly
- Understand input/output schemas, docstrings, and descriptions
- WITHOUT calling the tools themselves at this stage
### Step 3: Developing Understanding
Repeat steps 1 & 2 until you have a good understanding:
- Iterate multiple times
- Think about the kinds of tasks you want to create
- Refine your understanding
- At NO stage should you READ the code of the MCP server implementation itself
- Use your intuition and understanding to create reasonable, realistic, but VERY challenging tasks
### Step 4: Read-Only Content Inspection
After understanding the API and tools, USE the MCP server tools:
- Inspect content using READ-ONLY and NON-DESTRUCTIVE operations ONLY
- Goal: identify specific content (e.g., users, channels, messages, projects, tasks) for creating realistic questions
- Should NOT call any tools that modify state
- Will NOT read the code of the MCP server implementation itself
- Parallelize this step with individual sub-agents pursuing independent explorations
- Ensure each subagent is only performing READ-ONLY, NON-DESTRUCTIVE, and IDEMPOTENT operations
- BE CAREFUL: SOME TOOLS may return LOTS OF DATA which would cause you to run out of CONTEXT
- Make INCREMENTAL, SMALL, AND TARGETED tool calls for exploration
- In all tool call requests, use the `limit` parameter to limit results (<10)
- Use pagination
### Step 5: Task Generation
After inspecting the content, create 10 human-readable questions:
- An LLM should be able to answer these with the MCP server
- Follow all question and answer guidelines above
## Output Format
Each QA pair consists of a question and an answer. The output should be an XML file with this structure:
```xml
<evaluation>
<qa_pair>
<question>Find the project created in Q2 2024 with the highest number of completed tasks. What is the project name?</question>
<answer>Website Redesign</answer>
</qa_pair>
<qa_pair>
<question>Search for issues labeled as "bug" that were closed in March 2024. Which user closed the most issues? Provide their username.</question>
<answer>sarah_dev</answer>
</qa_pair>
<qa_pair>
<question>Look for pull requests that modified files in the /api directory and were merged between January 1 and January 31, 2024. How many different contributors worked on these PRs?</question>
<answer>7</answer>
</qa_pair>
<qa_pair>
<question>Find the repository with the most stars that was created before 2023. What is the repository name?</question>
<answer>data-pipeline</answer>
</qa_pair>
</evaluation>
```
## Evaluation Examples
### Good Questions
**Example 1: Multi-hop question requiring deep exploration (GitHub MCP)**
```xml
<qa_pair>
<question>Find the repository that was archived in Q3 2023 and had previously been the most forked project in the organization. What was the primary programming language used in that repository?</question>
<answer>Python</answer>
</qa_pair>
```
This question is good because:
- Requires multiple searches to find archived repositories
- Needs to identify which had the most forks before archival
- Requires examining repository details for the language
- Answer is a simple, verifiable value
- Based on historical (closed) data that won't change
**Example 2: Requires understanding context without keyword matching (Project Management MCP)**
```xml
<qa_pair>
<question>Locate the initiative focused on improving customer onboarding that was completed in late 2023. The project lead created a retrospective document after completion. What was the lead's role title at that time?</question>
<answer>Product Manager</answer>
</qa_pair>
```
This question is good because:
- Doesn't use specific project name ("initiative focused on improving customer onboarding")
- Requires finding completed projects from specific timeframe
- Needs to identify the project lead and their role
- Requires understanding context from retrospective documents
- Answer is human-readable and stable
- Based on completed work (won't change)
**Example 3: Complex aggregation requiring multiple steps (Issue Tracker MCP)**
```xml
<qa_pair>
<question>Among all bugs reported in January 2024 that were marked as critical priority, which assignee resolved the highest percentage of their assigned bugs within 48 hours? Provide the assignee's username.</question>
<answer>alex_eng</answer>
</qa_pair>
```
This question is good because:
- Requires filtering bugs by date, priority, and status
- Needs to group by assignee and calculate resolution rates
- Requires understanding timestamps to determine 48-hour windows
- Tests pagination (potentially many bugs to process)
- Answer is a single username
- Based on historical data from specific time period
**Example 4: Requires synthesis across multiple data types (CRM MCP)**
```xml
<qa_pair>
<question>Find the account that upgraded from the Starter to Enterprise plan in Q4 2023 and had the highest annual contract value. What industry does this account operate in?</question>
<answer>Healthcare</answer>
</qa_pair>
```
This question is good because:
- Requires understanding subscription tier changes
- Needs to identify upgrade events in specific timeframe
- Requires comparing contract values
- Must access account industry information
- Answer is simple and verifiable
- Based on completed historical transactions
### Poor Questions
**Example 1: Answer changes over time**
```xml
<qa_pair>
<question>How many open issues are currently assigned to the engineering team?</question>
<answer>47</answer>
</qa_pair>
```
This question is poor because:
- The answer will change as issues are created, closed, or reassigned
- Not based on stable/stationary data
- Relies on "current state" which is dynamic
**Example 2: Too easy with keyword search**
```xml
<qa_pair>
<question>Find the pull request with title "Add authentication feature" and tell me who created it.</question>
<answer>developer123</answer>
</qa_pair>
```
This question is poor because:
- Can be solved with a straightforward keyword search for exact title
- Doesn't require deep exploration or understanding
- No synthesis or analysis needed
**Example 3: Ambiguous answer format**
```xml
<qa_pair>
<question>List all the repositories that have Python as their primary language.</question>
<answer>repo1, repo2, repo3, data-pipeline, ml-tools</answer>
</qa_pair>
```
This question is poor because:
- Answer is a list that could be returned in any order
- Difficult to verify with direct string comparison
- LLM might format differently (JSON array, comma-separated, newline-separated)
- Better to ask for a specific aggregate (count) or superlative (most stars)
## Verification Process
After creating evaluations:
1. **Examine the XML file** to understand the schema
2. **Load each task instruction** and in parallel using the MCP server and tools, identify the correct answer by attempting to solve the task YOURSELF
3. **Flag any operations** that require WRITE or DESTRUCTIVE operations
4. **Accumulate all CORRECT answers** and replace any incorrect answers in the document
5. **Remove any `<qa_pair>`** that require WRITE or DESTRUCTIVE operations
Remember to parallelize solving tasks to avoid running out of context, then accumulate all answers and make changes to the file at the end.
## Tips for Creating Quality Evaluations
1. **Think Hard and Plan Ahead** before generating tasks
2. **Parallelize Where Opportunity Arises** to speed up the process and manage context
3. **Focus on Realistic Use Cases** that humans would actually want to accomplish
4. **Create Challenging Questions** that test the limits of the MCP server's capabilities
5. **Ensure Stability** by using historical data and closed concepts
6. **Verify Answers** by solving the questions yourself using the MCP server tools
7. **Iterate and Refine** based on what you learn during the process
---
# Running Evaluations
After creating your evaluation file, you can use the provided evaluation harness to test your MCP server.
## Setup
1. **Install Dependencies**
```bash
pip install -r scripts/requirements.txt
```
Or install manually:
```bash
pip install anthropic mcp
```
2. **Set API Key**
```bash
export ANTHROPIC_API_KEY=your_api_key_here
```
## Evaluation File Format
Evaluation files use XML format with `<qa_pair>` elements:
```xml
<evaluation>
<qa_pair>
<question>Find the project created in Q2 2024 with the highest number of completed tasks. What is the project name?</question>
<answer>Website Redesign</answer>
</qa_pair>
<qa_pair>
<question>Search for issues labeled as "bug" that were closed in March 2024. Which user closed the most issues? Provide their username.</question>
<answer>sarah_dev</answer>
</qa_pair>
</evaluation>
```
## Running Evaluations
The evaluation script (`scripts/evaluation.py`) supports three transport types:
**Important:**
- **stdio transport**: The evaluation script automatically launches and manages the MCP server process for you. Do not run the server manually.
- **sse/http transports**: You must start the MCP server separately before running the evaluation. The script connects to the already-running server at the specified URL.
### 1. Local STDIO Server
For locally-run MCP servers (script launches the server automatically):
```bash
python scripts/evaluation.py \
-t stdio \
-c python \
-a my_mcp_server.py \
evaluation.xml
```
With environment variables:
```bash
python scripts/evaluation.py \
-t stdio \
-c python \
-a my_mcp_server.py \
-e API_KEY=abc123 \
-e DEBUG=true \
evaluation.xml
```
### 2. Server-Sent Events (SSE)
For SSE-based MCP servers (you must start the server first):
```bash
python scripts/evaluation.py \
-t sse \
-u https://example.com/mcp \
-H "Authorization: Bearer token123" \
-H "X-Custom-Header: value" \
evaluation.xml
```
### 3. HTTP (Streamable HTTP)
For HTTP-based MCP servers (you must start the server first):
```bash
python scripts/evaluation.py \
-t http \
-u https://example.com/mcp \
-H "Authorization: Bearer token123" \
evaluation.xml
```
## Command-Line Options
```
usage: evaluation.py [-h] [-t {stdio,sse,http}] [-m MODEL] [-c COMMAND]
[-a ARGS [ARGS ...]] [-e ENV [ENV ...]] [-u URL]
[-H HEADERS [HEADERS ...]] [-o OUTPUT]
eval_file
positional arguments:
eval_file Path to evaluation XML file
optional arguments:
-h, --help Show help message
-t, --transport Transport type: stdio, sse, or http (default: stdio)
-m, --model Claude model to use (default: claude-3-7-sonnet-20250219)
-o, --output Output file for report (default: print to stdout)
stdio options:
-c, --command Command to run MCP server (e.g., python, node)
-a, --args Arguments for the command (e.g., server.py)
-e, --env Environment variables in KEY=VALUE format
sse/http options:
-u, --url MCP server URL
-H, --header HTTP headers in 'Key: Value' format
```
## Output
The evaluation script generates a detailed report including:
- **Summary Statistics**:
- Accuracy (correct/total)
- Average task duration
- Average tool calls per task
- Total tool calls
- **Per-Task Results**:
- Prompt and expected response
- Actual response from the agent
- Whether the answer was correct (✅/❌)
- Duration and tool call details
- Agent's summary of its approach
- Agent's feedback on the tools
### Save Report to File
```bash
python scripts/evaluation.py \
-t stdio \
-c python \
-a my_server.py \
-o evaluation_report.md \
evaluation.xml
```
## Complete Example Workflow
Here's a complete example of creating and running an evaluation:
1. **Create your evaluation file** (`my_evaluation.xml`):
```xml
<evaluation>
<qa_pair>
<question>Find the user who created the most issues in January 2024. What is their username?</question>
<answer>alice_developer</answer>
</qa_pair>
<qa_pair>
<question>Among all pull requests merged in Q1 2024, which repository had the highest number? Provide the repository name.</question>
<answer>backend-api</answer>
</qa_pair>
<qa_pair>
<question>Find the project that was completed in December 2023 and had the longest duration from start to finish. How many days did it take?</question>
<answer>127</answer>
</qa_pair>
</evaluation>
```
2. **Install dependencies**:
```bash
pip install -r scripts/requirements.txt
export ANTHROPIC_API_KEY=your_api_key
```
3. **Run evaluation**:
```bash
python scripts/evaluation.py \
-t stdio \
-c python \
-a github_mcp_server.py \
-e GITHUB_TOKEN=ghp_xxx \
-o github_eval_report.md \
my_evaluation.xml
```
4. **Review the report** in `github_eval_report.md` to:
- See which questions passed/failed
- Read the agent's feedback on your tools
- Identify areas for improvement
- Iterate on your MCP server design
## Troubleshooting
### Connection Errors
If you get connection errors:
- **STDIO**: Verify the command and arguments are correct
- **SSE/HTTP**: Check the URL is accessible and headers are correct
- Ensure any required API keys are set in environment variables or headers
### Low Accuracy
If many evaluations fail:
- Review the agent's feedback for each task
- Check if tool descriptions are clear and comprehensive
- Verify input parameters are well-documented
- Consider whether tools return too much or too little data
- Ensure error messages are actionable
### Timeout Issues
If tasks are timing out:
- Use a more capable model (e.g., `claude-3-7-sonnet-20250219`)
- Check if tools are returning too much data
- Verify pagination is working correctly
- Consider simplifying complex questions

# MCP Server Development Best Practices and Guidelines
## Overview
This document compiles essential best practices and guidelines for building Model Context Protocol (MCP) servers. It covers naming conventions, tool design, response formats, pagination, error handling, security, and compliance requirements.
---
## Quick Reference
### Server Naming
- **Python**: `{service}_mcp` (e.g., `slack_mcp`)
- **Node/TypeScript**: `{service}-mcp-server` (e.g., `slack-mcp-server`)
### Tool Naming
- Use snake_case with service prefix
- Format: `{service}_{action}_{resource}`
- Example: `slack_send_message`, `github_create_issue`
### Response Formats
- Support both JSON and Markdown formats
- JSON for programmatic processing
- Markdown for human readability
### Pagination
- Always respect `limit` parameter
- Return `has_more`, `next_offset`, `total_count`
- Default to 20-50 items
### Character Limits
- Set CHARACTER_LIMIT constant (typically 25,000)
- Truncate gracefully with clear messages
- Provide guidance on filtering

## 1. Server Naming Conventions
Follow these standardized naming patterns for MCP servers:
**Python**: Use format `{service}_mcp` (lowercase with underscores)
- Examples: `slack_mcp`, `github_mcp`, `jira_mcp`, `stripe_mcp`
**Node/TypeScript**: Use format `{service}-mcp-server` (lowercase with hyphens)
- Examples: `slack-mcp-server`, `github-mcp-server`, `jira-mcp-server`
The name should be:
- General (not tied to specific features)
- Descriptive of the service/API being integrated
- Easy to infer from the task description
- Without version numbers or dates
---
## 2. Tool Naming and Design
### Tool Naming Best Practices
1. **Use snake_case**: `search_users`, `create_project`, `get_channel_info`
2. **Include service prefix**: Anticipate that your MCP server may be used alongside other MCP servers
- Use `slack_send_message` instead of just `send_message`
- Use `github_create_issue` instead of just `create_issue`
- Use `asana_list_tasks` instead of just `list_tasks`
3. **Be action-oriented**: Start with verbs (get, list, search, create, etc.)
4. **Be specific**: Avoid generic names that could conflict with other servers
5. **Maintain consistency**: Use consistent naming patterns within your server
### Tool Design Guidelines
- Tool descriptions must narrowly and unambiguously describe functionality
- Descriptions must precisely match actual functionality
- Should not create confusion with other MCP servers
- Should provide tool annotations (readOnlyHint, destructiveHint, idempotentHint, openWorldHint)
- Keep tool operations focused and atomic
---
## 3. Response Format Guidelines
All tools that return data should support multiple formats for flexibility:
### JSON Format (`response_format="json"`)
- Machine-readable structured data
- Include all available fields and metadata
- Consistent field names and types
- Suitable for programmatic processing
- Use for when LLMs need to process data further
### Markdown Format (`response_format="markdown"`, typically default)
- Human-readable formatted text
- Use headers, lists, and formatting for clarity
- Convert timestamps to human-readable format (e.g., "2024-01-15 10:30:00 UTC" instead of epoch)
- Show display names with IDs in parentheses (e.g., "@john.doe (U123456)")
- Omit verbose metadata (e.g., show only one profile image URL, not all sizes)
- Group related information logically
- Use for when presenting information to users
---
## 4. Pagination Best Practices
For tools that list resources:
- **Always respect the `limit` parameter**: Never load all results when a limit is specified
- **Implement pagination**: Use `offset` or cursor-based pagination
- **Return pagination metadata**: Include `has_more`, `next_offset`/`next_cursor`, `total_count`
- **Never load all results into memory**: Especially important for large datasets
- **Default to reasonable limits**: 20-50 items is typical
- **Include clear pagination info in responses**: Make it easy for LLMs to request more data
Example pagination response structure:
```json
{
"total": 150,
"count": 20,
"offset": 0,
"items": [...],
"has_more": true,
"next_offset": 20
}
```
---
## 5. Character Limits and Truncation
To prevent overwhelming responses with too much data:
- **Define CHARACTER_LIMIT constant**: Typically 25,000 characters at module level
- **Check response size before returning**: Measure the final response length
- **Truncate gracefully with clear indicators**: Let the LLM know data was truncated
- **Provide guidance on filtering**: Suggest how to use parameters to reduce results
- **Include truncation metadata**: Show what was truncated and how to get more
Example truncation handling:
```python
CHARACTER_LIMIT = 25000
if len(result) > CHARACTER_LIMIT:
truncated_data = data[:max(1, len(data) // 2)]
response["truncated"] = True
response["truncation_message"] = (
f"Response truncated from {len(data)} to {len(truncated_data)} items. "
f"Use 'offset' parameter or add filters to see more results."
)
```
---
## 6. Transport Options
MCP servers support multiple transport mechanisms for different deployment scenarios:
### Stdio Transport
**Best for**: Command-line tools, local integrations, subprocess execution
**Characteristics**:
- Standard input/output stream communication
- Simple setup, no network configuration needed
- Runs as a subprocess of the client
- Ideal for desktop applications and CLI tools
**Use when**:
- Building tools for local development environments
- Integrating with desktop applications (e.g., Claude Desktop)
- Creating command-line utilities
- Single-user, single-session scenarios
### HTTP Transport
**Best for**: Web services, remote access, multi-client scenarios
**Characteristics**:
- Request-response pattern over HTTP
- Supports multiple simultaneous clients
- Can be deployed as a web service
- Requires network configuration and security considerations
**Use when**:
- Serving multiple clients simultaneously
- Deploying as a cloud service
- Integration with web applications
- Need for load balancing or scaling
### Server-Sent Events (SSE) Transport
**Best for**: Real-time updates, push notifications, streaming data
**Characteristics**:
- One-way server-to-client streaming over HTTP
- Enables real-time updates without polling
- Long-lived connections for continuous data flow
- Built on standard HTTP infrastructure
**Use when**:
- Clients need real-time data updates
- Implementing push notifications
- Streaming logs or monitoring data
- Progressive result delivery for long operations
### Transport Selection Criteria
| Criterion | Stdio | HTTP | SSE |
|-----------|-------|------|-----|
| **Deployment** | Local | Remote | Remote |
| **Clients** | Single | Multiple | Multiple |
| **Communication** | Bidirectional | Request-Response | Server-Push |
| **Complexity** | Low | Medium | Medium-High |
| **Real-time** | No | No | Yes |

## 10. OAuth and Security Best Practices
### Authentication and Authorization
MCP servers that connect to external services should implement proper authentication:
**OAuth 2.1 Implementation:**
- Use secure OAuth 2.1 with certificates from recognized authorities
- Validate access tokens before processing requests
- Only accept tokens specifically intended for your server
- Reject tokens without proper audience claims
- Never pass through tokens received from MCP clients
**API Key Management:**
- Store API keys in environment variables, never in code
- Validate keys on server startup
- Provide clear error messages when authentication fails
- Use secure transmission for sensitive credentials
### Input Validation and Security
**Always validate inputs:**
- Sanitize file paths to prevent directory traversal
- Validate URLs and external identifiers
- Check parameter sizes and ranges
- Prevent command injection in system calls
- Use schema validation (Pydantic/Zod) for all inputs

- Log security-relevant errors server-side
- Provide helpful but not revealing error messages
- Clean up resources after errors
### Privacy and Data Protection
**Data collection principles:**
- Only collect data strictly necessary for functionality
- Don't collect extraneous conversation data
- Don't collect PII unless explicitly required for the tool's purpose
- Provide clear information about what data is accessed
**Data transmission:**
- Don't send data to servers outside your organization without disclosure
- Use secure transmission (HTTPS) for all network communication
- Validate certificates for external services
---
## 11. Resource Management Best Practices
1. Only suggest necessary resources
2. Use clear, descriptive names for roots
3. Handle resource boundaries properly
4. Respect client control over resources
5. Use model-controlled primitives (tools) for automatic data exposure
---
## 12. Prompt Management Best Practices

# Tools
> Enable LLMs to perform actions through your server
Tools are a powerful primitive in the Model Context Protocol (MCP) that enable servers to expose executable functionality to clients. Through tools, LLMs can interact with external systems, perform computations, and take actions in the real world.
<Note>
Tools are designed to be **model-controlled**, meaning that tools are exposed from servers to clients with the intention of the AI model being able to automatically invoke them (with a human in the loop to grant approval).
</Note>
## Overview
Tools in MCP allow servers to expose executable functions that can be invoked by clients and used by LLMs to perform actions. Key aspects of tools include:
* **Discovery**: Clients can obtain a list of available tools by sending a `tools/list` request
* **Invocation**: Tools are called using the `tools/call` request, where servers perform the requested operation and return results
* **Flexibility**: Tools can range from simple calculations to complex API interactions
Like [resources](/docs/concepts/resources), tools are identified by unique names and can include descriptions to guide their usage. However, unlike resources, tools represent dynamic operations that can modify state or interact with external systems.
## Tool definition structure
Each tool is defined with the following structure:
```typescript
{
name: string; // Unique identifier for the tool
description?: string; // Human-readable description
inputSchema: { // JSON Schema for the tool's parameters
type: "object",
properties: { ... } // Tool-specific parameters
},
annotations?: { // Optional hints about tool behavior
title?: string; // Human-readable title for the tool
readOnlyHint?: boolean; // If true, the tool does not modify its environment
destructiveHint?: boolean; // If true, the tool may perform destructive updates
idempotentHint?: boolean; // If true, repeated calls with same args have no additional effect
openWorldHint?: boolean; // If true, tool interacts with external entities
}
}
```
## Implementing tools
Here's an example of implementing a basic tool in an MCP server:
<Tabs>
<Tab title="TypeScript">
```typescript
const server = new Server({
name: "example-server",
version: "1.0.0"
}, {
capabilities: {
tools: {}
}
});
// Define available tools
server.setRequestHandler(ListToolsRequestSchema, async () => {
return {
tools: [{
name: "calculate_sum",
description: "Add two numbers together",
inputSchema: {
type: "object",
properties: {
a: { type: "number" },
b: { type: "number" }
},
required: ["a", "b"]
}
}]
};
});
// Handle tool execution
server.setRequestHandler(CallToolRequestSchema, async (request) => {
if (request.params.name === "calculate_sum") {
const { a, b } = request.params.arguments;
return {
content: [
{
type: "text",
text: String(a + b)
}
]
};
}
throw new Error("Tool not found");
});
```
</Tab>
<Tab title="Python">
```python
app = Server("example-server")
@app.list_tools()
async def list_tools() -> list[types.Tool]:
return [
types.Tool(
name="calculate_sum",
description="Add two numbers together",
inputSchema={
"type": "object",
"properties": {
"a": {"type": "number"},
"b": {"type": "number"}
},
"required": ["a", "b"]
}
)
]
@app.call_tool()
async def call_tool(
name: str,
arguments: dict
) -> list[types.TextContent | types.ImageContent | types.EmbeddedResource]:
if name == "calculate_sum":
a = arguments["a"]
b = arguments["b"]
result = a + b
return [types.TextContent(type="text", text=str(result))]
raise ValueError(f"Tool not found: {name}")
```
</Tab>
</Tabs>
## Example tool patterns
Here are some examples of types of tools that a server could provide:
### System operations
Tools that interact with the local system:
```typescript
{
name: "execute_command",
description: "Run a shell command",
inputSchema: {
type: "object",
properties: {
command: { type: "string" },
args: { type: "array", items: { type: "string" } }
}
}
}
```
### API integrations
Tools that wrap external APIs:
```typescript
{
name: "github_create_issue",
description: "Create a GitHub issue",
inputSchema: {
type: "object",
properties: {
title: { type: "string" },
body: { type: "string" },
labels: { type: "array", items: { type: "string" } }
}
}
}
```
### Data processing
Tools that transform or analyze data:
```typescript
{
name: "analyze_csv",
description: "Analyze a CSV file",
inputSchema: {
type: "object",
properties: {
filepath: { type: "string" },
operations: {
type: "array",
items: {
enum: ["sum", "average", "count"]
}
}
}
}
}
```
## Best practices
When implementing tools:
1. Provide clear, descriptive names and descriptions
2. Use detailed JSON Schema definitions for parameters
3. Include examples in tool descriptions to demonstrate how the model should use them
4. Implement proper error handling and validation
5. Use progress reporting for long operations
6. Keep tool operations focused and atomic
7. Document expected return value structures
8. Implement proper timeouts
9. Consider rate limiting for resource-intensive operations
10. Log tool usage for debugging and monitoring
### Tool name conflicts
MCP client applications and MCP server proxies may encounter tool name conflicts when building their own tool lists. For example, two connected MCP servers `web1` and `web2` may both expose a tool named `search_web`.
Applications may disambiguiate tools with one of the following strategies (among others; not an exhaustive list):
* Concatenating a unique, user-defined server name with the tool name, e.g. `web1___search_web` and `web2___search_web`. This strategy may be preferable when unique server names are already provided by the user in a configuration file.
* Generating a random prefix for the tool name, e.g. `jrwxs___search_web` and `6cq52___search_web`. This strategy may be preferable in server proxies where user-defined unique names are not available.
* Using the server URI as a prefix for the tool name, e.g. `web1.example.com:search_web` and `web2.example.com:search_web`. This strategy may be suitable when working with remote MCP servers.
Note that the server-provided name from the initialization flow is not guaranteed to be unique and is not generally suitable for disambiguation purposes.
## Security considerations
When exposing tools:
### Input validation
* Validate all parameters against the schema
* Sanitize file paths and system commands
* Validate URLs and external identifiers
* Check parameter sizes and ranges
* Prevent command injection
### Access control
* Implement authentication where needed
* Use appropriate authorization checks
* Audit tool usage
* Rate limit requests
* Monitor for abuse
### Error handling
* Don't expose internal errors to clients
* Log security-relevant errors
* Handle timeouts appropriately
* Clean up resources after errors
* Validate return values
## Tool discovery and updates
MCP supports dynamic tool discovery:
1. Clients can list available tools at any time
2. Servers can notify clients when tools change using `notifications/tools/list_changed`
3. Tools can be added or removed during runtime
4. Tool definitions can be updated (though this should be done carefully)
## Error handling
Tool errors should be reported within the result object, not as MCP protocol-level errors. This allows the LLM to see and potentially handle the error. When a tool encounters an error:
1. Set `isError` to `true` in the result
2. Include error details in the `content` array
Here's an example of proper error handling for tools:
<Tabs>
<Tab title="TypeScript">
```typescript
try {
// Tool operation
const result = performOperation();
return {
content: [
{
type: "text",
text: `Operation successful: ${result}`
}
]
};
} catch (error) {
return {
isError: true,
content: [
{
type: "text",
text: `Error: ${error.message}`
}
]
};
}
```
</Tab>
<Tab title="Python">
```python
try:
# Tool operation
result = perform_operation()
return types.CallToolResult(
content=[
types.TextContent(
type="text",
text=f"Operation successful: {result}"
)
]
)
except Exception as error:
return types.CallToolResult(
isError=True,
content=[
types.TextContent(
type="text",
text=f"Error: {str(error)}"
)
]
)
```
</Tab>
</Tabs>
This approach allows the LLM to see that an error occurred and potentially take corrective action or request human intervention.
## Tool annotations
Tool annotations provide additional metadata about a tool's behavior, helping clients understand how to present and manage tools. These annotations are hints that describe the nature and impact of a tool, but should not be relied upon for security decisions.
### Purpose of tool annotations
Tool annotations serve several key purposes:
1. Provide UX-specific information without affecting model context
2. Help clients categorize and present tools appropriately
3. Convey information about a tool's potential side effects
4. Assist in developing intuitive interfaces for tool approval
### Available tool annotations
The MCP specification defines the following annotations for tools:
| Annotation | Type | Default | Description |
| ----------------- | ------- | ------- | ------------------------------------------------------------------------------------------------------------------------------------ |
| `title` | string | - | A human-readable title for the tool, useful for UI display |
| `readOnlyHint` | boolean | false | If true, indicates the tool does not modify its environment |
| `destructiveHint` | boolean | true | If true, the tool may perform destructive updates (only meaningful when `readOnlyHint` is false) |
| `idempotentHint` | boolean | false | If true, calling the tool repeatedly with the same arguments has no additional effect (only meaningful when `readOnlyHint` is false) |
| `openWorldHint` | boolean | true | If true, the tool may interact with an "open world" of external entities |
### Example usage
Here's how to define tools with annotations for different scenarios:
```typescript
// A read-only search tool
{
name: "web_search",
description: "Search the web for information",
inputSchema: {
type: "object",
properties: {
query: { type: "string" }
},
required: ["query"]
},
annotations: {
title: "Web Search",
readOnlyHint: true,
openWorldHint: true
}
}
// A destructive file deletion tool
{
name: "delete_file",
description: "Delete a file from the filesystem",
inputSchema: {
type: "object",
properties: {
path: { type: "string" }
},
required: ["path"]
},
annotations: {
title: "Delete File",
readOnlyHint: false,
destructiveHint: true,
idempotentHint: true,
openWorldHint: false
}
}
// A non-destructive database record creation tool
{
name: "create_record",
description: "Create a new record in the database",
inputSchema: {
type: "object",
properties: {
table: { type: "string" },
data: { type: "object" }
},
required: ["table", "data"]
},
annotations: {
title: "Create Database Record",
readOnlyHint: false,
destructiveHint: false,
idempotentHint: false,
openWorldHint: false
}
}
```
### Integrating annotations in server implementation
<Tabs>
<Tab title="TypeScript">
```typescript
server.setRequestHandler(ListToolsRequestSchema, async () => {
return {
tools: [{
name: "calculate_sum",
description: "Add two numbers together",
inputSchema: {
type: "object",
properties: {
a: { type: "number" },
b: { type: "number" }
},
required: ["a", "b"]
},
annotations: {
title: "Calculate Sum",
readOnlyHint: true,
openWorldHint: false
}
}]
};
});
```
</Tab>
<Tab title="Python">
```python
from mcp.server.fastmcp import FastMCP
mcp = FastMCP("example-server")
@mcp.tool(
annotations={
"title": "Calculate Sum",
"readOnlyHint": True,
"openWorldHint": False
}
)
async def calculate_sum(a: float, b: float) -> str:
"""Add two numbers together.
Args:
a: First number to add
b: Second number to add
"""
result = a + b
return str(result)
```
</Tab>
</Tabs>
### Best practices for tool annotations
1. **Be accurate about side effects**: Clearly indicate whether a tool modifies its environment and whether those modifications are destructive.
2. **Use descriptive titles**: Provide human-friendly titles that clearly describe the tool's purpose.
3. **Indicate idempotency properly**: Mark tools as idempotent only if repeated calls with the same arguments truly have no additional effect.
4. **Set appropriate open/closed world hints**: Indicate whether a tool interacts with a closed system (like a database) or an open system (like the web).
5. **Remember annotations are hints**: All properties in ToolAnnotations are hints and not guaranteed to provide a faithful description of tool behavior. Clients should never make security-critical decisions based solely on annotations.
## Testing tools
A comprehensive testing strategy for MCP tools should cover:
* **Functional testing**: Verify tools execute correctly with valid inputs and handle invalid inputs appropriately
* **Integration testing**: Test tool interaction with external systems using both real and mocked dependencies
* **Security testing**: Validate authentication, authorization, input sanitization, and rate limiting
* **Performance testing**: Check behavior under load, timeout handling, and resource cleanup
* **Error handling**: Ensure tools properly report errors through the MCP protocol and clean up resources

# Node/TypeScript MCP Server Implementation Guide
## Overview
This document provides Node/TypeScript-specific best practices and examples for implementing MCP servers using the MCP TypeScript SDK. It covers project structure, server setup, tool registration patterns, input validation with Zod, error handling, and complete working examples.
---
## Quick Reference
### Key Imports
```typescript
import { McpServer } from "@modelcontextprotocol/sdk/server/mcp.js";
import { StdioServerTransport } from "@modelcontextprotocol/sdk/server/stdio.js";
import { z } from "zod";
import axios, { AxiosError } from "axios";
```
### Server Initialization
```typescript
const server = new McpServer({
name: "service-mcp-server",
version: "1.0.0"
});
```
### Tool Registration Pattern
```typescript
server.registerTool("tool_name", {...config}, async (params) => {
// Implementation
});
```
---
## MCP TypeScript SDK
The official MCP TypeScript SDK provides:
- `McpServer` class for server initialization
- `registerTool` method for tool registration
- Zod schema integration for runtime input validation
- Type-safe tool handler implementations
See the MCP SDK documentation in the references for complete details.
## Server Naming Convention
Node/TypeScript MCP servers must follow this naming pattern:
- **Format**: `{service}-mcp-server` (lowercase with hyphens)
- **Examples**: `github-mcp-server`, `jira-mcp-server`, `stripe-mcp-server`
The name should be:
- General (not tied to specific features)
- Descriptive of the service/API being integrated
- Easy to infer from the task description
- Without version numbers or dates
## Project Structure
Create the following structure for Node/TypeScript MCP servers:
```
{service}-mcp-server/
├── package.json
├── tsconfig.json
├── README.md
├── src/
│ ├── index.ts # Main entry point with McpServer initialization
│ ├── types.ts # TypeScript type definitions and interfaces
│ ├── tools/ # Tool implementations (one file per domain)
│ ├── services/ # API clients and shared utilities
│ ├── schemas/ # Zod validation schemas
│ └── constants.ts # Shared constants (API_URL, CHARACTER_LIMIT, etc.)
└── dist/ # Built JavaScript files (entry point: dist/index.js)
```
## Tool Implementation
### Tool Naming
Use snake_case for tool names (e.g., "search_users", "create_project", "get_channel_info") with clear, action-oriented names.
**Avoid Naming Conflicts**: Include the service context to prevent overlaps:
- Use "slack_send_message" instead of just "send_message"
- Use "github_create_issue" instead of just "create_issue"
- Use "asana_list_tasks" instead of just "list_tasks"
### Tool Structure
Tools are registered using the `registerTool` method with the following requirements:
- Use Zod schemas for runtime input validation and type safety
- The `description` field must be explicitly provided - JSDoc comments are NOT automatically extracted
- Explicitly provide `title`, `description`, `inputSchema`, and `annotations`
- The `inputSchema` must be a Zod schema object (not a JSON schema)
- Type all parameters and return values explicitly
```typescript
import { McpServer } from "@modelcontextprotocol/sdk/server/mcp.js";
import { z } from "zod";
const server = new McpServer({
name: "example-mcp",
version: "1.0.0"
});
// Zod schema for input validation
const UserSearchInputSchema = z.object({
query: z.string()
.min(2, "Query must be at least 2 characters")
.max(200, "Query must not exceed 200 characters")
.describe("Search string to match against names/emails"),
limit: z.number()
.int()
.min(1)
.max(100)
.default(20)
.describe("Maximum results to return"),
offset: z.number()
.int()
.min(0)
.default(0)
.describe("Number of results to skip for pagination"),
response_format: z.nativeEnum(ResponseFormat)
.default(ResponseFormat.MARKDOWN)
.describe("Output format: 'markdown' for human-readable or 'json' for machine-readable")
}).strict();
// Type definition from Zod schema
type UserSearchInput = z.infer<typeof UserSearchInputSchema>;
server.registerTool(
"example_search_users",
{
title: "Search Example Users",
description: `Search for users in the Example system by name, email, or team.
This tool searches across all user profiles in the Example platform, supporting partial matches and various search filters. It does NOT create or modify users, only searches existing ones.
Args:
- query (string): Search string to match against names/emails
- limit (number): Maximum results to return, between 1-100 (default: 20)
- offset (number): Number of results to skip for pagination (default: 0)
- response_format ('markdown' | 'json'): Output format (default: 'markdown')
Returns:
For JSON format: Structured data with schema:
{
"total": number, // Total number of matches found
"count": number, // Number of results in this response
"offset": number, // Current pagination offset
"users": [
{
"id": string, // User ID (e.g., "U123456789")
"name": string, // Full name (e.g., "John Doe")
"email": string, // Email address
"team": string, // Team name (optional)
"active": boolean // Whether user is active
}
],
"has_more": boolean, // Whether more results are available
"next_offset": number // Offset for next page (if has_more is true)
}
Examples:
- Use when: "Find all marketing team members" -> params with query="team:marketing"
- Use when: "Search for John's account" -> params with query="john"
- Don't use when: You need to create a user (use example_create_user instead)
Error Handling:
- Returns "Error: Rate limit exceeded" if too many requests (429 status)
- Returns "No users found matching '<query>'" if search returns empty`,
inputSchema: UserSearchInputSchema,
annotations: {
readOnlyHint: true,
destructiveHint: false,
idempotentHint: true,
openWorldHint: true
}
},
async (params: UserSearchInput) => {
try {
// Input validation is handled by Zod schema
// Make API request using validated parameters
const data = await makeApiRequest<any>(
"users/search",
"GET",
undefined,
{
q: params.query,
limit: params.limit,
offset: params.offset
}
);
const users = data.users || [];
const total = data.total || 0;
if (!users.length) {
return {
content: [{
type: "text",
text: `No users found matching '${params.query}'`
}]
};
}
// Format response based on requested format
let result: string;
if (params.response_format === ResponseFormat.MARKDOWN) {
// Human-readable markdown format
const lines: string[] = [`# User Search Results: '${params.query}'`, ""];
lines.push(`Found ${total} users (showing ${users.length})`);
lines.push("");
for (const user of users) {
lines.push(`## ${user.name} (${user.id})`);
lines.push(`- **Email**: ${user.email}`);
if (user.team) {
lines.push(`- **Team**: ${user.team}`);
}
lines.push("");
}
result = lines.join("\n");
} else {
// Machine-readable JSON format
const response: any = {
total,
count: users.length,
offset: params.offset,
users: users.map((user: any) => ({
id: user.id,
name: user.name,
email: user.email,
...(user.team ? { team: user.team } : {}),
active: user.active ?? true
}))
};
// Add pagination info if there are more results
if (total > params.offset + users.length) {
response.has_more = true;
response.next_offset = params.offset + users.length;
}
result = JSON.stringify(response, null, 2);
}
return {
content: [{
type: "text",
text: result
}]
};
} catch (error) {
return {
content: [{
type: "text",
text: handleApiError(error)
}]
};
}
}
);
```
## Zod Schemas for Input Validation
Zod provides runtime type validation:
```typescript
import { z } from "zod";
// Basic schema with validation
const CreateUserSchema = z.object({
name: z.string()
.min(1, "Name is required")
.max(100, "Name must not exceed 100 characters"),
email: z.string()
.email("Invalid email format"),
age: z.number()
.int("Age must be a whole number")
.min(0, "Age cannot be negative")
.max(150, "Age cannot be greater than 150")
}).strict(); // Use .strict() to forbid extra fields
// Enums
enum ResponseFormat {
MARKDOWN = "markdown",
JSON = "json"
}
const SearchSchema = z.object({
response_format: z.nativeEnum(ResponseFormat)
.default(ResponseFormat.MARKDOWN)
.describe("Output format")
});
// Optional fields with defaults
const PaginationSchema = z.object({
limit: z.number()
.int()
.min(1)
.max(100)
.default(20)
.describe("Maximum results to return"),
offset: z.number()
.int()
.min(0)
.default(0)
.describe("Number of results to skip")
});
```
## Response Format Options
Support multiple output formats for flexibility:
```typescript
enum ResponseFormat {
MARKDOWN = "markdown",
JSON = "json"
}
const inputSchema = z.object({
query: z.string(),
response_format: z.nativeEnum(ResponseFormat)
.default(ResponseFormat.MARKDOWN)
.describe("Output format: 'markdown' for human-readable or 'json' for machine-readable")
});
```
**Markdown format**:
- Use headers, lists, and formatting for clarity
- Convert timestamps to human-readable format
- Show display names with IDs in parentheses
- Omit verbose metadata
- Group related information logically
**JSON format**:
- Return complete, structured data suitable for programmatic processing
- Include all available fields and metadata
- Use consistent field names and types
## Pagination Implementation
For tools that list resources:
```typescript
const ListSchema = z.object({
limit: z.number().int().min(1).max(100).default(20),
offset: z.number().int().min(0).default(0)
});
async function listItems(params: z.infer<typeof ListSchema>) {
const data = await apiRequest(params.limit, params.offset);
const response = {
total: data.total,
count: data.items.length,
offset: params.offset,
items: data.items,
has_more: data.total > params.offset + data.items.length,
next_offset: data.total > params.offset + data.items.length
? params.offset + data.items.length
: undefined
};
return JSON.stringify(response, null, 2);
}
```
## Character Limits and Truncation
Add a CHARACTER_LIMIT constant to prevent overwhelming responses:
```typescript
// At module level in constants.ts
export const CHARACTER_LIMIT = 25000; // Maximum response size in characters
async function searchTool(params: SearchInput) {
let result = generateResponse(data);
// Check character limit and truncate if needed
if (result.length > CHARACTER_LIMIT) {
const truncatedData = data.slice(0, Math.max(1, data.length / 2));
response.data = truncatedData;
response.truncated = true;
response.truncation_message =
`Response truncated from ${data.length} to ${truncatedData.length} items. ` +
`Use 'offset' parameter or add filters to see more results.`;
result = JSON.stringify(response, null, 2);
}
return result;
}
```
## Error Handling
Provide clear, actionable error messages:
```typescript
import axios, { AxiosError } from "axios";
function handleApiError(error: unknown): string {
if (error instanceof AxiosError) {
if (error.response) {
switch (error.response.status) {
case 404:
return "Error: Resource not found. Please check the ID is correct.";
case 403:
return "Error: Permission denied. You don't have access to this resource.";
case 429:
return "Error: Rate limit exceeded. Please wait before making more requests.";
default:
return `Error: API request failed with status ${error.response.status}`;
}
} else if (error.code === "ECONNABORTED") {
return "Error: Request timed out. Please try again.";
}
}
return `Error: Unexpected error occurred: ${error instanceof Error ? error.message : String(error)}`;
}
```
## Shared Utilities
Extract common functionality into reusable functions:
```typescript
// Shared API request function
async function makeApiRequest<T>(
endpoint: string,
method: "GET" | "POST" | "PUT" | "DELETE" = "GET",
data?: any,
params?: any
): Promise<T> {
try {
const response = await axios({
method,
url: `${API_BASE_URL}/${endpoint}`,
data,
params,
timeout: 30000,
headers: {
"Content-Type": "application/json",
"Accept": "application/json"
}
});
return response.data;
} catch (error) {
throw error;
}
}
```
## Async/Await Best Practices
Always use async/await for network requests and I/O operations:
```typescript
// Good: Async network request
async function fetchData(resourceId: string): Promise<ResourceData> {
const response = await axios.get(`${API_URL}/resource/${resourceId}`);
return response.data;
}
// Bad: Promise chains
function fetchData(resourceId: string): Promise<ResourceData> {
return axios.get(`${API_URL}/resource/${resourceId}`)
.then(response => response.data); // Harder to read and maintain
}
```
## TypeScript Best Practices
1. **Use Strict TypeScript**: Enable strict mode in tsconfig.json
2. **Define Interfaces**: Create clear interface definitions for all data structures
3. **Avoid `any`**: Use proper types or `unknown` instead of `any`
4. **Zod for Runtime Validation**: Use Zod schemas to validate external data
5. **Type Guards**: Create type guard functions for complex type checking
6. **Error Handling**: Always use try-catch with proper error type checking
7. **Null Safety**: Use optional chaining (`?.`) and nullish coalescing (`??`)
```typescript
// Good: Type-safe with Zod and interfaces
interface UserResponse {
id: string;
name: string;
email: string;
team?: string;
active: boolean;
}
const UserSchema = z.object({
id: z.string(),
name: z.string(),
email: z.string().email(),
team: z.string().optional(),
active: z.boolean()
});
type User = z.infer<typeof UserSchema>;
async function getUser(id: string): Promise<User> {
const data = await apiCall(`/users/${id}`);
return UserSchema.parse(data); // Runtime validation
}
// Bad: Using any
async function getUser(id: string): Promise<any> {
return await apiCall(`/users/${id}`); // No type safety
}
```

});
```

## Advanced MCP Features
### Resource Registration
Expose data as resources for efficient, URI-based access:
```typescript
import { ResourceTemplate } from "@modelcontextprotocol/sdk/types.js";
// Register a resource with URI template
server.registerResource(
{
uri: "file://documents/{name}",
name: "Document Resource",
description: "Access documents by name",
mimeType: "text/plain"
},
async (uri: string) => {
// Extract parameter from URI
const match = uri.match(/^file:\/\/documents\/(.+)$/);
if (!match) {
throw new Error("Invalid URI format");
}
const documentName = match[1];
const content = await loadDocument(documentName);
return {
contents: [{
uri,
mimeType: "text/plain",
text: content
}]
};
}
);
// List available resources dynamically
server.registerResourceList(async () => {
const documents = await getAvailableDocuments();
return {
resources: documents.map(doc => ({
uri: `file://documents/${doc.name}`,
name: doc.name,
mimeType: "text/plain",
description: doc.description
}))
};
});
```
**When to use Resources vs Tools:**
- **Resources**: For data access with simple URI-based parameters
- **Tools**: For complex operations requiring validation and business logic
- **Resources**: When data is relatively static or template-based
- **Tools**: When operations have side effects or complex workflows
### Multiple Transport Options
The TypeScript SDK supports different transport mechanisms:
```typescript
import { StdioServerTransport } from "@modelcontextprotocol/sdk/server/stdio.js";
import { SSEServerTransport } from "@modelcontextprotocol/sdk/server/sse.js";
// Stdio transport (default - for CLI tools)
const stdioTransport = new StdioServerTransport();
await server.connect(stdioTransport);
// SSE transport (for real-time web updates)
const sseTransport = new SSEServerTransport("/message", response);
await server.connect(sseTransport);
// HTTP transport (for web services)
// Configure based on your HTTP framework integration
```
**Transport selection guide:**
- **Stdio**: Command-line tools, subprocess integration, local development
- **HTTP**: Web services, remote access, multiple simultaneous clients
- **SSE**: Real-time updates, server-push notifications, web dashboards
### Notification Support
Notify clients when server state changes:
```typescript
// Notify when tools list changes
server.notification({
method: "notifications/tools/list_changed"
});
// Notify when resources change
server.notification({
method: "notifications/resources/list_changed"
});
```
Use notifications sparingly - only when server capabilities genuinely change.
---
## Code Best Practices
### Code Composability and Reusability
Your implementation MUST prioritize composability and code reuse:
1. **Extract Common Functionality**:
- Create reusable helper functions for operations used across multiple tools
- Build shared API clients for HTTP requests instead of duplicating code
- Centralize error handling logic in utility functions
- Extract business logic into dedicated functions that can be composed
- Extract shared markdown or JSON field selection & formatting functionality
2. **Avoid Duplication**:
- NEVER copy-paste similar code between tools
- If you find yourself writing similar logic twice, extract it into a function
- Common operations like pagination, filtering, field selection, and formatting should be shared
- Authentication/authorization logic should be centralized
## Building and Running
Always build your TypeScript code before running:
```bash
# Build the project
npm run build
# Run the server
npm start
# Development with auto-reload
npm run dev
```
Always ensure `npm run build` completes successfully before considering the implementation complete.
## Quality Checklist

# Python MCP Server Implementation Guide
## Overview
This document provides Python-specific best practices and examples for implementing MCP servers using the MCP Python SDK. It covers server setup, tool registration patterns, input validation with Pydantic, error handling, and complete working examples.
---
## Quick Reference
### Key Imports
```python
from mcp.server.fastmcp import FastMCP
from pydantic import BaseModel, Field, field_validator, ConfigDict
from typing import Optional, List, Dict, Any
from enum import Enum
import httpx
```
### Server Initialization
```python
mcp = FastMCP("service_mcp")
```
### Tool Registration Pattern
```python
@mcp.tool(name="tool_name", annotations={...})
async def tool_function(params: InputModel) -> str:
# Implementation
pass
```
---
## MCP Python SDK and FastMCP
The official MCP Python SDK provides FastMCP, a high-level framework for building MCP servers. It provides:
- Automatic description and inputSchema generation from function signatures and docstrings
- Pydantic model integration for input validation
- Decorator-based tool registration with `@mcp.tool`
**For complete SDK documentation, use WebFetch to load:**
`https://raw.githubusercontent.com/modelcontextprotocol/python-sdk/main/README.md`
## Server Naming Convention
Python MCP servers must follow this naming pattern:
- **Format**: `{service}_mcp` (lowercase with underscores)
- **Examples**: `github_mcp`, `jira_mcp`, `stripe_mcp`
The name should be:
- General (not tied to specific features)
- Descriptive of the service/API being integrated
- Easy to infer from the task description
- Without version numbers or dates
## Tool Implementation
### Tool Naming
Use snake_case for tool names (e.g., "search_users", "create_project", "get_channel_info") with clear, action-oriented names.
**Avoid Naming Conflicts**: Include the service context to prevent overlaps:
- Use "slack_send_message" instead of just "send_message"
- Use "github_create_issue" instead of just "create_issue"
- Use "asana_list_tasks" instead of just "list_tasks"
### Tool Structure with FastMCP
Tools are defined using the `@mcp.tool` decorator with Pydantic models for input validation:
```python
from pydantic import BaseModel, Field, ConfigDict
from mcp.server.fastmcp import FastMCP
# Initialize the MCP server
mcp = FastMCP("example_mcp")
# Define Pydantic model for input validation
class ServiceToolInput(BaseModel):
'''Input model for service tool operation.'''
model_config = ConfigDict(
str_strip_whitespace=True, # Auto-strip whitespace from strings
validate_assignment=True, # Validate on assignment
extra='forbid' # Forbid extra fields
)
param1: str = Field(..., description="First parameter description (e.g., 'user123', 'project-abc')", min_length=1, max_length=100)
param2: Optional[int] = Field(default=None, description="Optional integer parameter with constraints", ge=0, le=1000)
tags: Optional[List[str]] = Field(default_factory=list, description="List of tags to apply", max_items=10)
@mcp.tool(
name="service_tool_name",
annotations={
"title": "Human-Readable Tool Title",
"readOnlyHint": True, # Tool does not modify environment
"destructiveHint": False, # Tool does not perform destructive operations
"idempotentHint": True, # Repeated calls have no additional effect
"openWorldHint": False # Tool does not interact with external entities
}
)
async def service_tool_name(params: ServiceToolInput) -> str:
'''Tool description automatically becomes the 'description' field.
This tool performs a specific operation on the service. It validates all inputs
using the ServiceToolInput Pydantic model before processing.
Args:
params (ServiceToolInput): Validated input parameters containing:
- param1 (str): First parameter description
- param2 (Optional[int]): Optional parameter with default
- tags (Optional[List[str]]): List of tags
Returns:
str: JSON-formatted response containing operation results
'''
# Implementation here
pass
```
## Pydantic v2 Key Features
- Use `model_config` instead of nested `Config` class
- Use `field_validator` instead of deprecated `validator`
- Use `model_dump()` instead of deprecated `dict()`
- Validators require `@classmethod` decorator
- Type hints are required for validator methods
```python
from pydantic import BaseModel, Field, field_validator, ConfigDict
class CreateUserInput(BaseModel):
model_config = ConfigDict(
str_strip_whitespace=True,
validate_assignment=True
)
name: str = Field(..., description="User's full name", min_length=1, max_length=100)
email: str = Field(..., description="User's email address", pattern=r'^[\w\.-]+@[\w\.-]+\.\w+$')
age: int = Field(..., description="User's age", ge=0, le=150)
@field_validator('email')
@classmethod
def validate_email(cls, v: str) -> str:
if not v.strip():
raise ValueError("Email cannot be empty")
return v.lower()
```
## Response Format Options
Support multiple output formats for flexibility:
```python
from enum import Enum
class ResponseFormat(str, Enum):
'''Output format for tool responses.'''
MARKDOWN = "markdown"
JSON = "json"
class UserSearchInput(BaseModel):
query: str = Field(..., description="Search query")
response_format: ResponseFormat = Field(
default=ResponseFormat.MARKDOWN,
description="Output format: 'markdown' for human-readable or 'json' for machine-readable"
)
```
**Markdown format**:
- Use headers, lists, and formatting for clarity
- Convert timestamps to human-readable format (e.g., "2024-01-15 10:30:00 UTC" instead of epoch)
- Show display names with IDs in parentheses (e.g., "@john.doe (U123456)")
- Omit verbose metadata (e.g., show only one profile image URL, not all sizes)
- Group related information logically
**JSON format**:
- Return complete, structured data suitable for programmatic processing
- Include all available fields and metadata
- Use consistent field names and types
## Pagination Implementation
For tools that list resources:
```python
class ListInput(BaseModel):
limit: Optional[int] = Field(default=20, description="Maximum results to return", ge=1, le=100)
offset: Optional[int] = Field(default=0, description="Number of results to skip for pagination", ge=0)
async def list_items(params: ListInput) -> str:
# Make API request with pagination
data = await api_request(limit=params.limit, offset=params.offset)
# Return pagination info
response = {
"total": data["total"],
"count": len(data["items"]),
"offset": params.offset,
"items": data["items"],
"has_more": data["total"] > params.offset + len(data["items"]),
"next_offset": params.offset + len(data["items"]) if data["total"] > params.offset + len(data["items"]) else None
}
return json.dumps(response, indent=2)
```
## Character Limits and Truncation
Add a CHARACTER_LIMIT constant to prevent overwhelming responses:
```python
# At module level
CHARACTER_LIMIT = 25000 # Maximum response size in characters
async def search_tool(params: SearchInput) -> str:
result = generate_response(data)
# Check character limit and truncate if needed
if len(result) > CHARACTER_LIMIT:
# Truncate data and add notice
truncated_data = data[:max(1, len(data) // 2)]
response["data"] = truncated_data
response["truncated"] = True
response["truncation_message"] = (
f"Response truncated from {len(data)} to {len(truncated_data)} items. "
f"Use 'offset' parameter or add filters to see more results."
)
result = json.dumps(response, indent=2)
return result
```
## Error Handling
Provide clear, actionable error messages:
```python
def _handle_api_error(e: Exception) -> str:
'''Consistent error formatting across all tools.'''
if isinstance(e, httpx.HTTPStatusError):
if e.response.status_code == 404:

return "Error: Rate limit exceeded. Please wait before making more requests."

elif isinstance(e, httpx.TimeoutException):
return "Error: Request timed out. Please try again."
return f"Error: Unexpected error occurred: {type(e).__name__}"
```
## Shared Utilities
Extract common functionality into reusable functions:
```python
# Shared API request function
async def _make_api_request(endpoint: str, method: str = "GET", **kwargs) -> dict:
'''Reusable function for all API calls.'''
async with httpx.AsyncClient() as client:
response = await client.request(
method,
f"{API_BASE_URL}/{endpoint}",
timeout=30.0,
**kwargs
)
response.raise_for_status()
return response.json()
```
## Async/Await Best Practices
Always use async/await for network requests and I/O operations:
```python
# Good: Async network request
async def fetch_data(resource_id: str) -> dict:
async with httpx.AsyncClient() as client:
response = await client.get(f"{API_URL}/resource/{resource_id}")
response.raise_for_status()
return response.json()
# Bad: Synchronous request
def fetch_data(resource_id: str) -> dict:
response = requests.get(f"{API_URL}/resource/{resource_id}") # Blocks
return response.json()
```
## Type Hints
Use type hints throughout:
```python
from typing import Optional, List, Dict, Any
async def get_user(user_id: str) -> Dict[str, Any]:
data = await fetch_user(user_id)
return {"id": data["id"], "name": data["name"]}
```
## Tool Docstrings
Every tool must have comprehensive docstrings with explicit type information:
```python
async def search_users(params: UserSearchInput) -> str:
'''
Search for users in the Example system by name, email, or team.
This tool searches across all user profiles in the Example platform,
supporting partial matches and various search filters. It does NOT
create or modify users, only searches existing ones.
Args:
params (UserSearchInput): Validated input parameters containing:
- query (str): Search string to match against names/emails (e.g., "john", "@example.com", "team:marketing")
- limit (Optional[int]): Maximum results to return, between 1-100 (default: 20)
- offset (Optional[int]): Number of results to skip for pagination (default: 0)
Returns:
str: JSON-formatted string containing search results with the following schema:
Success response:
{
"total": int, # Total number of matches found
"count": int, # Number of results in this response
"offset": int, # Current pagination offset
"users": [
{
"id": str, # User ID (e.g., "U123456789")
"name": str, # Full name (e.g., "John Doe")
"email": str, # Email address (e.g., "john@example.com")
"team": str # Team name (e.g., "Marketing") - optional
}
]
}
Error response:
"Error: <error message>" or "No users found matching '<query>'"
Examples:
- Use when: "Find all marketing team members" -> params with query="team:marketing"
- Use when: "Search for John's account" -> params with query="john"
- Don't use when: You need to create a user (use example_create_user instead)
- Don't use when: You have a user ID and need full details (use example_get_user instead)
Error Handling:
- Input validation errors are handled by Pydantic model
- Returns "Error: Rate limit exceeded" if too many requests (429 status)
- Returns "Error: Invalid API authentication" if API key is invalid (401 status)
- Returns formatted list of results or "No users found matching 'query'"

## Advanced FastMCP Features
### Context Parameter Injection
FastMCP can automatically inject a `Context` parameter into tools for advanced capabilities like logging, progress reporting, resource reading, and user interaction:
```python
from mcp.server.fastmcp import FastMCP, Context
mcp = FastMCP("example_mcp")
@mcp.tool()
async def advanced_search(query: str, ctx: Context) -> str:
'''Advanced tool with context access for logging and progress.'''
# Report progress for long operations
await ctx.report_progress(0.25, "Starting search...")
# Log information for debugging
await ctx.log_info("Processing query", {"query": query, "timestamp": datetime.now()})
# Perform search
results = await search_api(query)
await ctx.report_progress(0.75, "Formatting results...")
# Access server configuration
server_name = ctx.fastmcp.name
return format_results(results)
@mcp.tool()
async def interactive_tool(resource_id: str, ctx: Context) -> str:
'''Tool that can request additional input from users.'''
# Request sensitive information when needed
api_key = await ctx.elicit(
prompt="Please provide your API key:",
input_type="password"
)
# Use the provided key
return await api_call(resource_id, api_key)
```
**Context capabilities:**
- `ctx.report_progress(progress, message)` - Report progress for long operations
- `ctx.log_info(message, data)` / `ctx.log_error()` / `ctx.log_debug()` - Logging
- `ctx.elicit(prompt, input_type)` - Request input from users
- `ctx.fastmcp.name` - Access server configuration
- `ctx.read_resource(uri)` - Read MCP resources
### Resource Registration
Expose data as resources for efficient, template-based access:
```python
@mcp.resource("file://documents/{name}")
async def get_document(name: str) -> str:
'''Expose documents as MCP resources.
Resources are useful for static or semi-static data that doesn't
require complex parameters. They use URI templates for flexible access.
'''
document_path = f"./docs/{name}"
with open(document_path, "r") as f:
return f.read()
@mcp.resource("config://settings/{key}")
async def get_setting(key: str, ctx: Context) -> str:
'''Expose configuration as resources with context.'''
settings = await load_settings()
return json.dumps(settings.get(key, {}))
```
**When to use Resources vs Tools:**
- **Resources**: For data access with simple parameters (URI templates)
- **Tools**: For complex operations with validation and business logic
### Structured Output Types
FastMCP supports multiple return types beyond strings:
```python
from typing import TypedDict
from dataclasses import dataclass
from pydantic import BaseModel
# TypedDict for structured returns
class UserData(TypedDict):
id: str
name: str
email: str
@mcp.tool()
async def get_user_typed(user_id: str) -> UserData:
'''Returns structured data - FastMCP handles serialization.'''
return {"id": user_id, "name": "John Doe", "email": "john@example.com"}
# Pydantic models for complex validation
class DetailedUser(BaseModel):
id: str
name: str
email: str
created_at: datetime
metadata: Dict[str, Any]
@mcp.tool()
async def get_user_detailed(user_id: str) -> DetailedUser:
'''Returns Pydantic model - automatically generates schema.'''
user = await fetch_user(user_id)
return DetailedUser(**user)
```
### Lifespan Management
Initialize resources that persist across requests:
```python
from contextlib import asynccontextmanager
@asynccontextmanager
async def app_lifespan():
'''Manage resources that live for the server's lifetime.'''
# Initialize connections, load config, etc.
db = await connect_to_database()
config = load_configuration()
# Make available to all tools
yield {"db": db, "config": config}
# Cleanup on shutdown
await db.close()
mcp = FastMCP("example_mcp", lifespan=app_lifespan)
@mcp.tool()
async def query_data(query: str, ctx: Context) -> str:
'''Access lifespan resources through context.'''
db = ctx.request_context.lifespan_state["db"]
results = await db.query(query)
return format_results(results)
```
### Multiple Transport Options
FastMCP supports different transport mechanisms:
```python
# Default: Stdio transport (for CLI tools)
if __name__ == "__main__":
mcp.run()
# HTTP transport (for web services)
if __name__ == "__main__":
mcp.run(transport="streamable_http", port=8000)
# SSE transport (for real-time updates)
if __name__ == "__main__":
mcp.run(transport="sse", port=8000)
```
**Transport selection:**
- **Stdio**: Command-line tools, subprocess integration
- **HTTP**: Web services, remote access, multiple clients
- **SSE**: Real-time updates, push notifications
---
## Code Best Practices
### Code Composability and Reusability
Your implementation MUST prioritize composability and code reuse:
1. **Extract Common Functionality**:
- Create reusable helper functions for operations used across multiple tools
- Build shared API clients for HTTP requests instead of duplicating code
- Centralize error handling logic in utility functions
- Extract business logic into dedicated functions that can be composed
- Extract shared markdown or JSON field selection & formatting functionality
2. **Avoid Duplication**:
- NEVER copy-paste similar code between tools
- If you find yourself writing similar logic twice, extract it into a function
- Common operations like pagination, filtering, field selection, and formatting should be shared
- Authentication/authorization logic should be centralized
### Python-Specific Best Practices
1. **Use Type Hints**: Always include type annotations for function parameters and return values
2. **Pydantic Models**: Define clear Pydantic models for all input validation
3. **Avoid Manual Validation**: Let Pydantic handle input validation with constraints
4. **Proper Imports**: Group imports (standard library, third-party, local)
5. **Error Handling**: Use specific exception types (httpx.HTTPStatusError, not generic Exception)
6. **Async Context Managers**: Use `async with` for resources that need cleanup
7. **Constants**: Define module-level constants in UPPER_CASE
## Quality Checklist

- [ ] All Pydantic Fields have explicit types and descriptions with constraints
- [ ] All tools have comprehensive docstrings with explicit input/output types
- [ ] Docstrings include complete schema structure for dict/JSON returns
- [ ] Pydantic models handle input validation (no manual validation needed)
### Advanced Features (where applicable)
- [ ] Context injection used for logging, progress, or elicitation
- [ ] Resources registered for appropriate data endpoints
- [ ] Lifespan management implemented for persistent connections
- [ ] Structured output types used (TypedDict, Pydantic models)
- [ ] Appropriate transport configured (stdio, HTTP, SSE)
### Code Quality
- [ ] File includes proper imports including Pydantic imports
- [ ] Pagination is properly implemented where applicable
- [ ] Large responses check CHARACTER_LIMIT and truncate with clear messages
- [ ] Filtering options are provided for potentially large result sets
- [ ] All async functions are properly defined with `async def`
- [ ] HTTP client usage follows async patterns with proper context managers
- [ ] Type hints are used throughout the code
- [ ] Constants are defined at module level in UPPER_CASE
### Testing
- [ ] Server runs successfully: `python your_server.py --help`
- [ ] All imports resolve correctly
- [ ] Sample tool calls work as expected
- [ ] Error scenarios handled gracefully

name: Developing Essays
description: Methodology for developing personal statements and analytical essays. Use when helping identify throughlines, resolve "too many ideas" paralysis, or clarify essay themes.
---
# Developing Essays
## Core Principle
**Actionability > Description**: Essays answer "what will you do?" not "who are you?"
Every theme must translate to **future behavior**.
---
## Output Format
When providing essay feedback, use this concise side-by-side format:
**Structure:**
- One focused paragraph per major issue
- Quote the problematic essay text, then provide commentary immediately after
- No lengthy preambles or excessive context
**Format pattern:**
> **[Issue name]:** "[quoted essay text]"
>
> [Single paragraph explaining the problem and suggesting fix]
**Constraints:**
- Maximum 3-4 issues per feedback session
- Each commentary paragraph: 3-5 sentences maximum
- Focus on actionable changes, not theory
- Use examples only when they directly demonstrate the fix
**What to prioritize:**
1. Missing forward projection (no "what will you do")
2. Circular narrative gaps (opening theme not closed in conclusion)
3. Weak openings (no hook, unclear stakes, unmotivated quotes)
4. Weak throughline or too many themes
5. Abstract language without concrete moments
6. Structural problems (formula, weak climax)
Omit exhaustive walkthroughs of the diagnostic framework unless specifically requested.
---
## Five-Step Diagnostic
**Note**: This is strategic (what to say). See "Tactical Writing Process" for mechanical execution (how to write).
### 1. Throughline Extraction
Find what the essay is *actually* about:
- What's the emotional climax?
- What was lost/gained?
- What pattern does this reveal?
- How will this manifest in the future?
**Example**:
- Surface: "Couldn't dance professionally"
- Deeper: "Lost external validation"
- Pattern: "Shifted from performing → discovering"
- Future: "Will seek clarity over recognition"
**For college essays**: State your throughline/values explicitly in the opening paragraph. Don't bury it in abstractions.
❌ Weak opening: "Growing up a member of Gen Z, I'm invested in learning how people negotiate power..."
✅ Strong opening: "I want to understand how policy can empower people, not just regulate them. This matters to me because..."
**Pattern**: Lead with clear personal values → then show how opportunities align with those values
### 2. Actionability Test
Ask: "What does this predict about future behavior?"
**Strong**: "I embrace imperfection" → "I will take intellectual risks, be vulnerable, try repeatedly from failure"
**Weak**: "I learned resilience" → (What specifically will you DO?)
**Rule**: If you can't name 3 concrete behaviors, the theme is too abstract.
#### Realization → Action Template
Many essays end with realizations but no behavior change. Use this template to convert insights to actions:
**Pattern**: "I realized [insight]. Now when [situation], I [specific behavior]."
**Examples:**
- ❌ Weak: "I realized food negotiates belonging"
- ✅ Strong: "I realized food negotiates belonging. Now when roommates mention what they eat, I ask about the story behind it"
- ❌ Weak: "Bridge-building is carried in everyday objects"
- ✅ Strong: "Bridge-building is carried in everyday objects. Now when I meet someone new, I notice what they carry—the book bag, the keychain, the coffee order—and ask about it"
**Test**: Can you name both the trigger situation AND the specific behavior? If not, still too abstract.
### 3. Subtraction Test
Too many themes? Subtract until one remains.
1. List all themes
2. Write "This essay is about [theme]" for each
3. Which feels most urgent?
4. Cut everything else
**One essay, one throughline.**
### 4. Forward Projection
Transform past → future capability.
❌ "I had to reinvent myself"
✅ "I reinvented myself once; I can do it again"
**Template**: "Because [experience], I am now capable of [specific action]"
#### Circular Narrative Structure
Bridge-building essays must close the loop: if opening establishes a theme, conclusion must show how that theme manifests in future action.
**Opening → Conclusion Circle:**
- Opening establishes: "[Core theme/value]"
- Body demonstrates: [Examples that prove theme]
- Conclusion projects: "Because of [theme], I will [specific action] when [context]"
**Test**: Replace conclusion with opening theme phrase. Does it connect naturally? If not, revise conclusion to explicitly callback.
**Example (NYU bridge-building essay):**
- Opening: "I'd grown through the words of others"
- Weak conclusion: "Bridge-building is carried in everyday objects" (realization, no callback)
- Strong conclusion: "At NYU, I'll grow others through my questions—not just learning from their words, but helping them discover meaning in their stories" (callbacks to "words of others" + shows future behavior)
**Common mistake**: Concluding with a beautiful insight that has no connection to the opening theme. This breaks the essay's coherence.
### 5. Concrete Translation
Abstract → tangible.
- Abstract: "I embrace imperfection"
- Concrete: "In the lab, when I killed the cricket, I documented the failure and adjusted technique"
- Three contexts:
- Academic: Share preliminary ideas in class
- Research: Publish null results
- Collaborative: Admit when I don't know
---
## Tactical Writing Process
Bottom-up sentence construction method. Use after identifying throughline (Steps 1-3).
### Two-Phase Refinement
**Phase 1: Paragraph-Level**
1. Break paragraph into components
2. For each component:
- Q1A: "Do I need this?"
- Q1B: "What relationships between components?"
- Q1C: "How does this relate to previous paragraph?"
- **Q-ALWAYS**: "How does this serve my throughline?"
**Phase 2: Sentence-Level**
1. For each sentence:
- Q2A: "What am I expressing?"
- Q2B: "Does this have a role in the paragraph?"
- Q2C: "What relationship with previous sentence?"
2. Build from simplest version → layer complexity
### "Start Dumb, Build Up" Method
**Core technique**: Strip to bare logic, then add descriptions.
**Process**:
1. Write simplest possible sentence (bare logic)
2. Layer in descriptions one at a time
3. Discover what's essential vs. "fluffy"
**Example**:
- Bare: "Law recognizes equality. Law allows local practice. This created problems."
- Layer 1: "Chinese law recognizes equality. But allows villages to govern by custom. This dispossessed Lei."
- Layer 2: "Chinese law upheld both villagers' land entitlements and villages' autonomy to govern by custom. Despite statutory protection, rural custom revoked married women's land rights, dispossessing Lei."
**Why**: Adding details to "nice-sounding" writing makes structure messy. Start ugly, build beautiful.
### Bottom-Up Detail Gathering
**Before structuring**, gather raw material:
1. **Collect**: Personal experiences, cases, observations, thoughts
2. **Extract**: General principles/patterns from details
3. **Connect**: Link principles to specific examples
4. **Merge**: Weave into coherent narrative
**Critical rule**: "Don't make it sound nice yet. Give personal experience and details first."
### Reading Strategy for Material Gathering
**Iterative skimming** (not deep reading first):
1. General sense: Why introduced? Why important?
2. Application: When/how used?
3. Explain test: "How would I explain this in 2-3 sentences?"
4. Extract: Take 1-2 technical concepts to show understanding
5. **Go back only when writing** (not during reading)
**Note**: "Skimming feels uncomfortable because you're not understanding everything. But it's much more time efficient."
### Relationship Mapping
**Every sentence must explicitly relate to surrounding sentences.**
**Method**:
- "What does this sentence do for the previous one?"
- "What does it set up for the next one?"
- "If relationship isn't clear, add transitional language"
**Example progression**:
- "From Lei's case..." (anchors to previous)
- "This drew me to common law..." (consequence)
- "Reading Kennedy's work..." (action taken)
### Three-Part Structure
For complex points:
1. **Express problem/tension**: State core issue
2. **Give example**: Concrete case
3. **Tie together**: Show connection
**Template**: "When reading [source], I found [tension]. In [specific case], [what happened]."
---
## Content Development Techniques
When student lacks material or struggles with abstraction.
### Content Provision
**When to use**: Student has structure but lacks substance.
**Method**: Provide concept clusters as building blocks.
**Example**:
Student writes: "Video journaling helped me understand myself"
Consultant provides: "Difference. Seeing different ways people live. Seeing intricacies. Listening. Culture. Attentiveness."
Student integrates: "Video journaling taught me to see difference—how others live, the intricacies of their daily rhythms. I learned listening as cultural practice, attentiveness as skill."
**Rule**: Give raw concepts, not finished sentences. Let them build.
### Compression Exercise
**When to use**: Writing is verbose, ideas buried in excess.
**Method**: Force radical reduction.
**Commands**:
- "Reduce this paragraph to 1 sentence"
- "Say this in 2 sentences maximum"
- "This paragraph can be a leading sentence"
**Example**:
Original (3 paragraphs): Discussion of dopamine, YouTube, vlogs, and why vlogging works
Compressed (2 sentences): "Laptop open, I resisted YouTube, the vlogs and dopamine. Yet my mind wondered—vloggers record unpolished moments for the public, yes, but for themselves too."
**Why it works**: Forces identification of core idea. Everything else was decoration.
### Experience Translation
**When to use**: Too many abstract concepts, not enough felt moments.
**Method**: Replace every abstraction with concrete experience.
**Pattern**:
- Abstract: "dopamine from watching vlogs"
- Concrete: "what you felt when watching"
- More concrete: "I watched a vlogger hesitate mid-sentence, laugh at herself. That hesitation felt familiar."
**Exercise**: "For each abstract term, give me the moment you experienced it."
**Examples**:
- "I learned resilience" → "When the cricket died, I documented it and tried again"
- "Embracing imperfection" → "I posted the video with my voice cracking"
- "Cultural awareness" → "In the matriarchal village, I interviewed a craftsman who spoke of overseas patrons"
**Rule**: If you can't name the moment, the concept isn't earned yet.
### Theoretical Framework Integration
**When to use**: Personal narrative lacks academic rigor.
**Method**: Find scholarly framework that explains student's experience.
**Examples from consultations**:
- Video journaling → Turner's "liminality" (anthropology)
- Dance discipline → Embodied cognition (philosophy)
- Village experience → Intersectionality (Crenshaw)
**Process**:
1. Identify pattern in student's experience
2. Ask: "What field studies this?"
3. Provide 1-2 key scholars/concepts
4. Student integrates: "Turner's concept of 'liminality' gave me language for what I'd been doing"
**Why it works**: Elevates personal story to intellectual inquiry.
---
## Key Techniques
### One Sentence Test
Complete: "This essay is about how [experience] taught me [insight], which means I will [action]"
If they can't → essay isn't ready.
### Uncomfortable Truth
The best throughline makes the writer slightly uncomfortable.
**Prompt**: "What are you afraid to say?"
That's often the throughline.
### So What? Chain
Ask "So what?" three times:
- "I embrace imperfection"
- So what? → "I'm willing to be vulnerable"
- So what? → "I take intellectual risks"
- So what? → "I contribute bold hypotheses, even if wrong"
Stop at third level—that's the actionable insight.
---
## Common Problems
**"Too many themes"**
→ Which most directly answers "what will you do in college?" Keep only that.
**"Unclear throughline"**
→ Complete: "If the reader remembers one thing: ___"
**"Emotional climax underdeveloped"**
→ Turning point gets 3 sentences? Expand to full paragraph.
---
## Red Flags
Phrases that signal weak throughline:
- "I learned a lot"
- "This experience shaped me"
- "I'm passionate about"
- "This taught me the importance of"
Push for specificity: What *exactly*? How *specifically*?
---
## For Analytical Essays
**Background vs. Analysis**:
- Background = Established facts needed to understand
- Analysis = Your interpretation using those facts
- Test: "Is this my argument or common knowledge?"
**Evidence Rule**: Every claim needs:
1. Textual evidence
2. Contextual support (historical/cultural)
3. Logical connection between evidence and claim
❌ "Snail Girl served a purpose after An Lushan rebellion"
✅ "Snail Girl reflects post-rebellion anxiety, evidenced by [textual detail] and increased courtesan culture in [source]"
---
## Essay Type Patterns
### Opening Strategies for Bridge-Building Essays
**Core principle**: Strong openings establish stakes before delivering insights.
❌ **Weak**: Start with advice/quote without context
✅ **Strong**: Start with moment of tension, then give insight that resolved it
**Before (unmotivated quote):**
> Professor Wong said, "Talk to people more."
**After (setup stakes first):**
> Reviewing famous ethnographies, I expected techniques for observation. Instead, Professor Wong paused: "The fieldwork I'm proudest of came from conversations I almost didn't have."
**Hook Types:**
1. **Surprising moment** - Expectation violated
- "I expected to learn interviewing tactics. Instead, he told me to stop taking notes."
2. **Tension** - Two opposing truths
- "The village preserved matriarchal tradition. Yet every woman I met had left to work in coastal cities."
3. **Vivid scene** - Drop reader into action
- "The boy approached singing. His mother, 2,000 miles away, had taught him the melody over FaceTime."
4. **Confession** - Admit uncomfortable truth
- "I spent three months analyzing communities. I never asked what the data meant to them."
**Test**: Could the essay start at paragraph 2 instead? If yes, paragraph 1 is weak—it's not doing work to engage the reader.
**Common mistake**: Generic statements about generation, society, or abstract concepts. These feel like padding.
- ❌ "Growing up a member of Gen Z, I'm invested in learning how people negotiate power..."
- ✅ "When the village elder refused my interview, I realized my questions were extracting data, not building trust."
### Thank-You Note / Mentor Essays
**Core principle**: Relationship-focus over achievement-focus.
❌ Achievement-focused: "I led 493 members, organized games, created mentorship programs..."
✅ Relationship-focused: "You taught me that persistence matters more than perfection. When you accepted me despite my 33% win rate..."
**Seven-part structure**:
1. **Introduce setting**: Where/how you met
2. **Establish mentor relationship**: Who they are to you
3. **Show transition**: How they empowered you
4. **Present problems**: Challenges in the community/space
5. **Detail your actions**: What you did (influenced by them)
6. **Reflect on growth**: What you learned from the process
7. **Final thank you**: Connect back to their specific impact
**Balancing analytical with personal**: You can include sociological/intellectual observations, but frame them as insights the mentor helped you discover.
**Example**:
- ❌ "I implemented rotating moderators and created participation guidelines..."
- ✅ "You taught me that access defines opportunity. When I saw the PeiWan economy create hierarchy in our group, I remembered your words and introduced rotating moderators..."
**Key**: Use observations to explain what the person taught you, not to showcase knowledge.
### "Why This College" Essays
**Specificity over name-dropping**: Show what you'd actually do, not just list programs.
❌ Vague: "I'm excited to join debates at the Philomathean Society"
✅ Specific: "At Philomathean Society, I want to bring debates on digital policy—how do we regulate platforms that shape identity formation?"
❌ Generic: "I'll use the Data Driven Discovery Initiative"
✅ Concrete: "Through DDDI, I plan to analyze social media discourse patterns using NLP to understand how marginalized communities build counter-narratives"
**Pattern**: Program/opportunity → specific question/project you'd pursue → why this connects to your values
**Test**: Could another applicant copy-paste this sentence? If yes, add more specificity.
---
## Consultation Flow
**First meeting**: Ask
- "What is this essay about?"
- "If you deleted half, what stays?"
- "What about your future, not just past?"
**Output**: 2-3 possible throughlines
**Second meeting**: Present options
"Here are three framings: [A→behavior], [B→behavior], [C→behavior]"
Ask: "Which feels uncomfortable to admit?"
→ Usually the right one.
**Revision**: Focus on
- Climax developed enough?
- Every paragraph serves throughline?
- Can we subtract anything?
- Conclusion projects forward?
**After structure is solid**, use Tactical Writing Process for sentence-level refinement.
---
## Mantras
1. "What will you do?" > "Who are you?"
2. One throughline, deeply excavated
3. Uncomfortable truth = right throughline
4. Abstract → concrete behaviors
5. Climax deserves most space
6. Evidence before interpretation
7. Start dumb, build up (bare logic → descriptions)
8. Every sentence must relate to adjacent sentences

- Code alignment fixed and verified
**Attribution Testing**: ✅
- Source documentation clearly credited
- MemMachine URL provided
- Features traced to documentation sections
---
## Problem-Solving Demonstrated
### Problem 1: Tool Limitation
**Issue**: WebFetch returns summarized content, not raw code examples
**Solution**: Recognized pages with higher code density (Quickstart) provide better content
**Outcome**: Successfully pivoted from Intro page (summary-only) to Quickstart guide (70+ KB of real code)
### Problem 2: Content-User Mismatch
**Issue**: First artifact was too conceptual; user wanted hands-on examples
**Solution**: Completely rebuilt with real curl commands, actual Python SDK code, working healthcare scenario
**Outcome**: User received exactly what was requested - hands-on tutorial with real code
### Problem 3: CSS Inheritance
**Issue**: Parent `text-align: center` cascaded to code blocks, affecting readability
**Solution**: Applied dual fix (CSS + React Tailwind classes) for robustness
**Outcome**: Code blocks now properly left-aligned across all browsers/contexts

- Debugging Guide (still applicable)
---
### 5. SESSION_SUMMARY.md
**Status**: ⏳ No Changes Required
**Why**: This file documents the real-world testing and iteration process, which is historical record. It accurately captures how the user identified the pedagogical approach as problematic and demanded code-first instead.
**Still Relevant Content**:
- Phase 1: Initial attempt with pedagogical approach
- Phase 2: User feedback ("I want hands-on with real code")
- Phase 3: Recovery and rebuild with Quickstart approach
- Phase 4: UX fix for code alignment
- All validation and learnings apply to code-first approach
---
### 6. INDEX.md
**Status**: ⏳ No Changes Required
**Why**: This file is purely navigational and doesn't describe the methodology. It still accurately points to SKILL.md, README.md, IMPLEMENTATION_NOTES.md, and SESSION_SUMMARY.md.
---
## Consistency Verification
### Cross-File Alignment
After updates, all files now consistently emphasize:
| Aspect | SKILL.md | README.md | UI_AND_CONTENT_REQUIREMENTS.md |
|--------|----------|-----------|------|
| First Section Goal | <5 min code | Running code <5 min | First section <5 minutes |
| Section Names | Action-oriented (Setup, Call, API, SDK) | Action-oriented examples | ⚙️ Setup, 🚀 First Call, etc. |
| Code Examples | Copy-paste executable, real endpoints | Copy-paste, real, no placeholders | Copy-paste, real payloads |
| No Fluff | No "learning objectives," "key takeaways" | No conceptual fluff | No objectives, takeaways, intros |
| Workflows | 3-5 connected API calls, data flow | Complete workflows, API sequences | 3-5 calls with input/output |
| Code Blocks | Dark theme, left-aligned, tabs | Copy buttons, dark, left-aligned | CRITICAL emphasis on left-aligned |
| Quality Criteria | 10-point code-first checklist | 10 success criteria | Code Quality checklist with code-first focus |
---
## Migration Path for Old Documentation
The following files from the previous iteration remain as legacy/archive:
- `REFRESHED_REQUIREMENTS_OVERVIEW.md` - Outdated, reflected brief transition state
- `.quibbler-messages.txt` - Historical observation log, still valid as reference
**Recommendation**: Archive these files or retain for historical reference, but treat the new SKILL.md + README.md + UI_AND_CONTENT_REQUIREMENTS.md as the definitive source of truth.
---
## Testing & Validation
### How to Verify the Updates
1. **Read SKILL.md** → Confirm 3 core principles are all pragmatic
2. **Read README.md** → Confirm example requests ask for copy-paste code
3. **Read UI_AND_CONTENT_REQUIREMENTS.md** → Confirm "What Must NOT Be Included" lists no learning objectives
4. **Cross-reference** → All three files should consistently emphasize code-first, no fluff
### Real-World Validation
The MemMachine tutorial (previously created) successfully demonstrates the code-first approach:
- ✅ Section 1: Setup command in <5 minutes
- ✅ Section 2: Real curl to actual endpoint
- ✅ Section 3: Three endpoints with actual JSON payloads
- ✅ Section 4: Real Python SDK code with imports and async/await
- ✅ Section 5: Healthcare bot workflow with connected API calls
- ✅ NO learning objectives
- ✅ NO conceptual explanations
- ✅ NO "key takeaways"
---

---
## Key Implementation Decisions
### 1. Single File Output (bundle.html)
**Decision**: Generate single self-contained HTML file rather than multi-file output
**Rationale**:
- ✅ Easy deployment - single file to copy anywhere
- ✅ No build process required for end-user
- ✅ Works in email, documentation, LMS systems
- ✅ No broken links or missing assets
- ✅ Git-friendly (single file for version control)
**Implementation**:
- Uses Parcel bundler with target: "browser"
- Inlines all CSS (Tailwind + custom styles)
- Inlines all JavaScript (React + dependencies)
- Result: ~300KB single HTML file
### 2. Exact Code Preservation
**Decision**: Copy code examples character-for-character from documentation
**Rationale**:
- ✅ Maintains learning fidelity - learners use documented code
- ✅ Reduces bugs - no transcription errors
- ✅ Simplifies attribution - exact match proves source
- ✅ Future-proofs - code works as documented
**Implementation Process**:
1. When fetching documentation, prioritize pages with concrete code
2. Copy code blocks directly into CodeBlock components
3. Never paraphrase or "improve" code
4. Include comments/annotations from original
5. Note any limitations in inline comments if needed
### 3. Progressive Disclosure Pattern
**Decision**: Order concepts from simple → complex, never introducing unexplained dependencies
**Rationale**:
- ✅ Prevents cognitive overload
- ✅ Allows learners to stop at any point with complete knowledge
- ✅ Enables skipping advanced sections for basic users
- ✅ Matches how documentation should be read
**Implementation Approach**:
1. Extract all concepts from documentation
2. Create dependency graph (Feature A requires Feature B knowledge)
3. Topological sort: ensure all prerequisites satisfy before introducing concept
4. Group related concepts into learning units
5. Verify each unit is coherent and self-contained
### 4. Attribution & Respect
**Decision**: Always preserve original authorship and provide clear sourcing
**Rationale**:
- ✅ Ethical - respects original authors' work
- ✅ Legal - maintains license compliance
- ✅ Educational - learners know source of information
- ✅ Quality assurance - shows where to find authoritative information
**Implementation Details**:
- Include source URL prominently
- Quote documentation with "According to [source]: '...'"
- Note which section each concept comes from
- Include license information if provided
- Link to original documentation when possible
---
## Technology Stack Rationale
### React + TypeScript
**Why**:
- Component-based architecture maps well to learning sections
- TypeScript ensures type safety in complex UI state
- Rich ecosystem for educational UI patterns
- Easy to refactor and enhance sections independently
### Tailwind CSS
**Why**:
- Responsive design with minimal custom CSS
- Dark theme suitable for code display
- `text-left` utility classes solve alignment issues
- Composable utilities for consistent styling
### Shadcn/ui
**Why**:
- Pre-built accessible components (Card, Tabs, Badge, Button)
- Based on Radix UI - production-quality foundations
- Easy to customize and extend
- Reduces boilerplate code for common patterns
### Parcel Bundler
**Why**:
- Zero-config build system
- Automatically inlines assets into single file
- Fast rebuild times during development
- Produces optimized single HTML output
---
## Common Patterns
### Pattern 1: CodeBlock Component
Used for displaying code snippets with copy functionality:
```typescript
<CodeBlock
code={exactCodeFromDocs}
language="python"
/>
```
**Features**:
- Syntax highlighting by language
- Dark background (`bg-slate-950`)
- Copy button with visual feedback
- Line numbers (optional)
- Text-left alignment (Tailwind + CSS)
**Styling Considerations**:
- Must explicitly set `text-left` (not inherited)
- Pre element needs `text-left` class
- Code element needs `text-left` class
- Ensures alignment regardless of parent styles
### Pattern 2: APIExample Component
Used for API documentation tutorials:
```typescript
<APIExample
title="Add Memory"
endpoint="/v1/memories"
method="POST"
curlCommand={exactCurlFromDocs}
requestBody={exampleRequest}
responseExample={exampleResponse}
/>
```
**Features**:
- Tabbed interface (cURL, Request, Response)
- Each tab contains copyable code blocks
- Shows realistic API interaction flow
- Helps readers understand before/after states
### Pattern 3: LearningObjective
Every section starts with clear learning goal:
```typescript
<LearningObjective
text="After this section, you'll understand Feature X and when to use it"
/>
```
**Purpose**:
- Sets learner expectations
- Provides clear success criteria
- Helps learners focus attention
- Enables self-assessment
### Pattern 4: DocumentationQuote
Highlights exact documentation statements:
```typescript
<DocumentationQuote
quote="Exact text from documentation"
source="Documentation Section Name"
url="Link to documentation page"
/>
```
**Styling**:
- Distinct visual treatment (border, background)
- Shows source attribution
- Maintains reading flow while highlighting importance
---
## Testing Strategy
### Phase 1: Content Accuracy Testing
- [ ] Verify each code example matches documentation exactly
- [ ] Check that all curl commands work (can test with curl)
- [ ] Verify Python SDK examples can be imported
- [ ] Ensure all URLs in references still work
### Phase 2: Progression Testing
- [ ] Can a learner read section 1 in isolation?
- [ ] Do all prerequisites exist before introducing a concept?
- [ ] Are there any confusing jumps in complexity?
- [ ] Can someone stop after any section with complete understanding?
### Phase 3: UX Testing
- [ ] Do code blocks display correctly on mobile?
- [ ] Can all code be copied successfully?
- [ ] Is navigation intuitive?
- [ ] Is dark theme readable for extended periods?
- [ ] Are code blocks left-aligned (not centered)?
### Phase 4: Attribution Testing
- [ ] Every concept has documentation quote
- [ ] Source sections are clearly noted
- [ ] Original author/URL is credited
- [ ] No claims made beyond what documentation states
---
## Known Limitations
### WebFetch Tool Behavior
- Returns AI-summarized markdown, not raw documentation
- Workaround: Fetch pages with higher code density (Quickstart vs Introduction)
- Limitation: Can't get completely raw HTML via WebFetch
### Code Example Availability
- Only tutorials can include code that exists in documentation
- Can't invent "example" code beyond what's documented
- When documentation lacks examples, must note this limitation
### Interactive Execution
- Code examples are display-only, not executable in artifact
- Workaround: Include clear instructions for running examples locally
- Can't execute external APIs from bundled artifact (CORS restrictions)
---
## Maintenance Guidelines
### When to Update
Update the tutorial when:
1. Documentation gets major updates
2. Code examples are found to be outdated
3. New versions released (API changes, deprecated features)
4. User provides feedback about confusing sections
5. Progression logic needs improvement
### Version Control
Always commit tutorials with:
```
Documentation Tutorial: [Documentation Name] - [Date]
- Updated to match [Documentation Version]
- Added/Modified/Removed: [Key changes]
- Tested with: [Test details]
Source: [Documentation URL]
```
### Testing Before Deployment
```bash
# 1. Build the artifact
npm run build # or parcel build
# 2. Open in browser
open bundle.html
# 3. Test on each section:
# - Code blocks copy correctly
# - All links work
# - No broken styling
# - Navigation functions
# 4. Test a few code examples locally
# - Copy curl commands, run them
# - Copy Python code, test imports
# - Verify output matches documented behavior
```
---
## Extending the Skill
### To Support New Documentation
1. **Fetch the documentation**
- Use WebFetch for initial content
- Use MCP Exa or direct fetch for richer content
- Look for Quickstart/Getting Started sections first
2. **Analyze structure**
- Identify all sections and features
- Extract exact quotes for each feature
- Collect all code examples
- Map dependencies
3. **Design progression**
- Zero-prerequisite topics first
- Build dependency graph
- Order from simple → complex
- Group related concepts
4. **Build artifact**
- Create React component with sections
- Use CodeBlock for code examples
- Use APIExample for API docs
- Include LearningObjective for each section
5. **Test thoroughly**
- Content accuracy (code matches docs)
- Progression logic (no unexplained jumps)
- UX quality (styling, alignment, copy buttons)
- Attribution (all sources credited)
### To Add New Component Types
Example: Adding a new "ConceptDiagram" component for architecture diagrams
```typescript
// 1. Create component
function ConceptDiagram({ title, svgUrl, description }) {
return (
<div className="my-4 p-4 bg-slate-900 rounded-lg">
<h4>{title}</h4>
<img src={svgUrl} alt={title} />
<p>{description}</p>
</div>
);
}
// 2. Add to main content flow
<ConceptDiagram
title="API Request Flow"
svgUrl="./diagrams/api-flow.svg"
description="How requests flow through the system"
/>
// 3. Test rendering and styling
// 4. Update SKILL.md with new pattern
// 5. Document in this file
```
---
## Performance Considerations
### Bundle Size
- Target: < 400KB for single HTML file
- Current: ~300KB (typical)
- Optimization: Parcel handles minification automatically
### Load Time
- Single file loads faster than multi-file artifact
- No additional HTTP requests after page load
- Dark theme reduces perceived latency (less "flashing")
### Rendering Performance
- React handles DOM efficiently
- Syntax highlighting done at build time
- No dynamic code evaluation
---
## Accessibility Considerations
### Currently Implemented
- ✅ Semantic HTML structure
- ✅ Color contrast in dark theme
- ✅ Keyboard navigation via Tab
- ✅ Alt text for diagrams (when present)
- ✅ Code blocks marked with language type
### Could Be Enhanced
- [ ] ARIA labels for interactive elements
- [ ] Transcripts for any embedded video
- [ ] Dyslexia-friendly font option
- [ ] High contrast mode toggle
- [ ] Screen reader optimization for code blocks
---
## Debugging Guide
### "Code block styling looks wrong"
Check:
1. Is `text-left` class present on CodeBlock div?
2. Is parent element using `text-align: center`?
3. Check browser dev tools - which CSS rule is winning?
Fix: Add explicit `!important` to text-left if inheritance issue:
```css
code, pre {
text-align: left !important;
}
```
### "Copy button not working"
Check:
1. Is Clipboard API available? (all modern browsers)
2. Does code block have a unique ID?
3. Check browser console for JavaScript errors
Test:
```javascript
// In browser console
navigator.clipboard.writeText("test text")
.then(() => console.log("Copy works"))
.catch(e => console.log("Copy failed:", e))
```
### "Documentation quote not showing"
Check:
1. Is quote text actually in documentation?
2. Is URL accessible?
3. Check for HTML entity encoding issues
### "Navigation doesn't work"
Check:
1. Are scroll IDs matching section anchor IDs?
2. Is React Router properly configured?
3. Check browser console for routing errors
---
## Future Enhancements
### Potential Features
1. **Interactive Code Sandbox**
- Execute code examples in browser
- Modify and re-run
- See live output
2. **Quiz/Knowledge Check**
- Auto-generated questions from content
- Feedback on answers
- Mastery tracking
3. **Search Within Tutorial**
- Full-text search of content
- Jump to relevant sections
- Highlight search terms
4. **Comments/Annotations**
- Users can add notes
- Share annotations
- Community discussions
5. **Multiple Language Support**
- Translate tutorial to other languages
- Language selector in UI
- RTL support
6. **Offline Mode**
- Service worker for offline access
- Download for PDF
- Work without internet

# Documentation Tutorial Skill
**Purpose**: Build hands-on, code-first tutorials from technical documentation. Extract real API endpoints, actual code examples, and working scenarios. Create interactive tutorials with copy-paste ready code, real request/response payloads, and step-by-step walkthroughs.
**Status**: ✅ Production Ready (Code-First Focus)
---
## Quick Start
### When to Use This Skill
Ask for the documentation-tutorial skill when you want to:
1. **Create hands-on API tutorials with real, working code**
- "Build a tutorial from the MemMachine API docs - make it copy-paste ready"
- "Create a step-by-step guide for Stripe API with real curl examples"
2. **Transform documentation into practical code walkthroughs**
- "Turn the Kubernetes CLI docs into a hands-on tutorial with real commands"
- "Make the GitHub API docs interactive with working cURL examples"
3. **Generate code-first learning paths with minimal fluff**
- "Create a tutorial showing real API usage with actual request/response payloads"
- "Build a guide that gets developers working code in 5 minutes"
4. **Build interactive guides focused on executable examples**
- "Create a tutorial with real, copy-paste code and actual endpoints"
- "Make a guide that shows what to do, not what to understand"
### Example Requests
```
"Build a code-first tutorial from this API documentation. Focus on
copy-paste executable code, real endpoints, and actual payloads.
No conceptual fluff - I want users running code in 5 minutes."
"Create a hands-on guide from this documentation. Show curl commands
with real endpoints, request/response JSON, and step-by-step workflows
using actual API calls."
"Transform this documentation into a practical tutorial with real
examples. Include setup instructions, first working API call, all
major endpoints with curl, and a complete real-world scenario."
```
---
## How It Works
The skill uses a **3-phase systematic workflow**:
### Phase 1: Code Extraction
- Find all real code examples in documentation (curl commands, SDKs, scripts)
- Extract actual API endpoints and request/response payloads
- Collect installation and setup commands
- Identify real-world workflow scenarios from docs
- Build a code inventory (not concept inventory)
### Phase 2: Tutorial Structure Design
- Plan action-oriented sections: Setup → First Call → Core Operations → SDK → Real Scenario
- Organize code blocks with tabs (curl | request | response)
- Design workflow walkthroughs showing how API calls connect
- Ensure all code is immediately executable (copy-paste ready)
### Phase 3: Interactive Artifact Creation
- Build React artifact with sidebar navigation and main content area
- Embed all code blocks with copy-to-clipboard functionality
- Create tabbed views for API examples (cURL + Request + Response)
- Add info cards showing endpoint, HTTP method, real use cases
- Dark theme with left-aligned monospace code
---
## Core Principles
The skill is built on three core principles:
### 1. ✓ Code-First, Not Conceptual
- Lead with working examples, not theory
- Every code block is copy-paste executable as-is
- Real endpoints (not `<placeholder>`), real data, real payloads
- Skip "what is X" unless essential - jump straight to "how to use X"
### 2. ✓ Interactive Code Exploration
- Show multiple views: cURL command + Request body + Response example
- Use real use cases from documentation (healthcare, CRM, not "test data")
- Complete workflows with all actual API calls shown step-by-step
- Display exactly what each API call returns
### 3. ✓ Minimal Friction, Maximum Practicality
- No conceptual fluff, no "learning objectives," no "key takeaways"
- Action-oriented section names: "⚙️ Setup & Install" not "Understanding Installation"
- Get developers to working code within 5 minutes
- Real, realistic data values throughout
---
## Output Format
The skill produces a **single interactive HTML file** (~300KB) containing:
✅ **Sidebar Navigation**
- Action-oriented section links (⚙️ Setup, 🚀 First Call, 🌐 REST API, etc.)
- Visual progress indicator
- Current section highlighting
✅ **Main Content Area**
- Section heading + one-line description
- Code blocks with copy-to-clipboard
- Tabbed interfaces for API examples (cURL | Request | Response)
- Info cards showing endpoint, HTTP method, real use cases
- Step-by-step workflow walkthroughs with actual API calls
✅ **Interactive Features**
- Copy button on every code block (copies to clipboard instantly)
- Tabs for exploring different views of API calls
- Dark theme optimized for code (slate-950 background)
- Left-aligned monospace code (NEVER centered)
- Responsive design for mobile/tablet/desktop
- Syntax highlighting by language (python, bash, json, etc.)
---
## Real-World Example
Here's what was created when testing with MemMachine documentation:
**Output Structure** - Pure hands-on focus:
1. **⚙️ Setup & Install** - Copy-paste installation command + verification curl (5 min)
2. **🚀 First API Call** - Real curl to `http://127.0.0.1:8080/v1/sessions` with response
3. **🌐 REST API** - Three endpoints (POST /memories, GET search, DELETE) with curl tabs
4. **🐍 Python SDK** - Actual working episodic_memory.add_memory_episode() code + async examples
5. **💾 Real Scenario** - Healthcare bot workflow: Store symptom → Search memories → Get response
**Code Quality**:
- All curl commands use actual endpoints (not `<localhost>` placeholders)
- Request/response JSON shows real structures with patient names, actual field names
- Python code copied exactly from docs with full imports and error handling
- Every code block copy-paste executable immediately
---
## Technical Stack
- **Build**: React + TypeScript + Tailwind CSS + shadcn/ui
- **Output**: Single self-contained HTML bundle.html
- **Code Theme**: Dark slate-950 background with syntax highlighting
- **Copy Function**: Native Clipboard API with visual feedback
- **Bundling**: Parcel (zero config, single-file output)
---
## Key Features
### Copy-Paste Ready Code ✓
All code examples are real, executable, from documentation. No `<placeholder>` syntax, no pseudocode, no "simplified versions." Just real, working code.
### Tabbed API Explorer ✓
Switch between views:
- **cURL tab**: Full curl command (ready to run)
- **Request tab**: JSON request body (copy to use in code)
- **Response tab**: Real response example (shows what you'll get)
### Action-Oriented Structure ✓
- Sections named for what you'll DO: "Setup & Install", "First API Call", "REST API"
- Not named for what you'll LEARN: "Understanding Setup", "Learning Concepts"
- Each section progresses logically to the next
- Users can complete real tasks after each section
### Developer-Optimized UX ✓
- Left-aligned code blocks (NOT centered - critical for readability)
- Dark theme reduces eye strain during extended coding sessions
- Copy button on every code block
- Monospace font with syntax highlighting by language
- Horizontal scroll for long lines (no awkward wrapping)
---
## Best Practices for Using This Skill
### ✓ Choose Documentation With Real Code Examples
The best tutorials come from docs that include real examples:
- **Best**: API Quickstart guides with curl examples
- **Good**: Reference documentation with code samples
- **Avoid**: Conceptual/overview documentation without examples
### ✓ Request Code-First Focus
Be explicit about your priorities:
- "Make this copy-paste ready - I want to run code immediately"
- "Use real API endpoints and payloads, not simplified examples"
- "Focus on how to use it, not how it works"
### ✓ Test Code Examples Before Using
While the skill extracts code from documentation:
- Try running a few curl commands
- Copy-paste SDK code and verify imports work
- Report if anything doesn't match the docs
### ✓ Request Workflow Walkthroughs
If the docs have real use cases, ask for them:
- "Show a complete workflow from start to finish"
- "Include actual API call sequences (not just single endpoints)"
- "Use a real scenario from your docs"
---
## Troubleshooting
### "I got too many conceptual introductions"
**Solution**: Request the skill extract from Quickstart/Getting Started sections instead of Introduction pages. Introductions summarize concepts; Quickstarts show actual code.
### "Code blocks are centered instead of left-aligned"
**Solution**: This is a rendering bug. The artifact should use `text-align: left` on all code blocks. Report this and it will be fixed immediately - code alignment matters for developer UX.
### "Missing some API endpoints"
**Solution**: The skill can only include code that's in the documentation. If an endpoint isn't documented with examples, it won't appear in the tutorial. You can request sections be added for undocumented features.
### "Need more workflow examples"
**Solution**: Request "real scenario" sections. Ask for complete workflows that show multiple API calls connected together (e.g., "store data → search → retrieve → use in response").
---
## Success Criteria
A code-first tutorial is successful when it:
1. ✓ **Copy-Paste Ready**: All code is immediately executable (curl works as-is, SDK imports work)
2. ✓ **Real Endpoints**: Uses actual URLs and payloads from documentation (no placeholders)
3. ✓ **Code Accuracy**: All examples match documentation exactly
4. ✓ **Quick Start**: First section gets users running code in <5 minutes
5. ✓ **No Fluff**: No learning objectives, no conceptual summaries, no "key takeaways"
6. ✓ **Real Data**: Examples use realistic values (patient names, actual field names, not "test")
7. ✓ **Complete Workflows**: Real scenarios show how API calls connect, step by step
8. ✓ **Interactive Tabs**: API examples show cURL + Request + Response in accessible tabs
9. ✓ **Dark Theme Code**: Readable code blocks with proper syntax highlighting
10. ✓ **User Can Do**: After following tutorial, user can accomplish real task with the API

---
## Development Timeline
### Phase 1: Initial Attempt (19:43-19:55)
- Created comprehensive SKILL.md documentation
- Built first artifact: High-level conceptual tutorial
- **Issue Identified**: Output was too conceptual, lacked hands-on code
### Phase 2: User Feedback (20:00:50)
- User rejected first artifact
- **User Quote**: "I want this to be much more hands on. With real code and real API calls and things like that, more than high level summaries"
- **Root Cause**: WebFetch tool returns AI-summarized content; intro page lacked concrete examples
- **Decision**: Pivot to better documentation source (Quickstart with 16,850+ bytes of actual code)
### Phase 3: Recovery & Rebuild (20:00:56-20:05:15)
- Fetched higher-quality documentation (Quickstart guide)
- Rebuilt entire tutorial with:
- Real curl commands from docs
- 70+ lines of actual Python SDK code
- Practical healthcare scenario with real API usage
- **Result**: Hands-on artifact meeting user requirements
### Phase 4: UX Fix (20:05:21-20:05:42)
- **Issue**: Code blocks centered instead of left-aligned
- **User Feedback**: "Note that your code blocks are aligned to the center, not left aligned."
- **Fix Applied**:
1. CSS: Removed `text-align: center` from #root, added explicit left-align for code/pre elements
2. React: Added `text-left` Tailwind classes to CodeBlock component
- **Rebuild**: Successful (749ms build time)
- **Final Output**: bundle.html (304K)
---
## Key Technical Insights
### WebFetch Tool Limitation
- Returns AI-summarized markdown, not raw documentation
- Requesting "raw text" or "complete content" doesn't bypass summarization
- Transformation happens at HTTP→markdown layer in tool architecture
- **Workaround**: Fetch pages with higher content density (Quickstart vs Introduction)
### CSS Inheritance Challenge
Parent element centering (`text-align: center`) cascaded to child code blocks. Solution required:
1. Remove centering from parent
2. Add explicit left-align to child code/pre elements
3. Use both CSS and Tailwind classes for robustness
### Code Example Quality
Real code examples (70+ lines) are FAR more valuable than summaries for developer education. Educational efficacy multiplied when:
- Examples are copy-pasteable from actual documentation
- Multiple example types shown (curl, Python SDK)
- Real-world scenarios included (healthcare bot)
- All examples functional and properly annotated
---

name: documentation-tutorial
description: Build hands-on, code-first tutorials from any primary source - technical documentation, codebases, APIs, tools, or other complex material. Extract real examples, working code, and concrete scenarios. Create tutorials using markdown (text-heavy summaries) or React artifacts (complex interactive workflows). Keywords - tutorial, codebase, API, hands-on, code-first, copy-paste, interactive, real examples, primary source
---
# Tutorial Developer from Primary Sources
Transform any primary source into hands-on, practical tutorials that prioritize real, working examples over conceptual explanations. Focus on what users need to *do*, not what they need to understand.
## Quick Decision Guide
**Step 1: Choose format**
- Text-heavy summary or CLI reference → Markdown
- Complex workflow with multiple steps → React Artifact
**Step 2: Follow the three pillars**
1. Real code/commands (not pseudocode)
2. Real use cases (concrete scenarios)
3. Mental model (one-sentence explanation)
## Core Principles
### The Three Pillars
Every tutorial must clearly answer:
1. **Real Code**: What's the actual code or command I run? (Copy-paste executable, no pseudocode)
2. **Real Use Cases**: When would I actually use this? (Concrete scenarios like "healthcare bot", not vague descriptions)
3. **Mental Model**: How does this work? (One-sentence explanation enabling independent problem-solving)
**Example:**
```
Mental Model: "AI generates interactive React components from natural language prompts, streaming in real-time."
Code:
curl -X POST https://api.thesys.dev/v1/ui/generate \
-H "Authorization: Bearer sk-thesys-key" \
-d '{"prompt": "Create a booking form", "model": "gpt-4"}'
Use Case: When you want users to book appointments without writing React,
send a prompt and stream the form directly into the page.
```
### Code-First Approach
- Lead with working examples, not theory
- Real endpoints (actual URLs, not `<placeholder>`)
- Exact payloads (complete JSON, not simplified)
- No high-level summaries unless essential
- Get users to running code within 5 minutes
## Systematic Workflow
### Phase 1: Extract from Primary Source
**Step 1: Identify Core Mental Model**
Answer: *"What's the one-sentence explanation that makes everything click?"*
Examples:
- API: "AI generates interactive UIs from prompts, streaming real-time"
- Tool: "PDFs are structured data; extract tables/text like CSV/JSON"
- Codebase: "Request flows through middleware → router → handler → response"
- Academic Paper: "YouTube Data API v3 lets you search videos, get metadata, and filter by captions/views/category using REST endpoints"
### Primary Source Types
**Documentation:** Official API docs, SDK references, CLI manuals
**Codebases:** Open source projects, example repos
**Tools:** Software applications, command-line utilities
**Academic Papers:** Research methodologies in appendices/supplementary materials
- Look for: Data collection procedures, API workflows, filtering criteria, implementation details
- Example: MINEDOJO paper Appendix D.1 documents exact YouTube API usage with 5-step workflow
- Extract: Step-by-step procedures, quota limits, legal considerations, real filtering parameters
- Value: More rigorous methodology than typical blog posts, validated by peer review
**Step 2: Find Real Examples**
Extract from docs/code:
- Working code (not pseudocode)
- CLI commands with actual flags
- API calls (curl + request/response)
- Config files, error cases
**Step 3: Extract Concrete Use Cases**
❌ **Wrong:** "Can be used for various applications like analytics, reporting, etc."
✅ **Right:**
1. **Analytics Dashboard**: User asks "show me sales by region" → AI generates chart
2. **Booking Flow**: Customer books appointment → form auto-generates with calendar
3. **Support Tickets**: Agent asks "show ticket queue" → interactive table generates
For each: What triggers it, what code is needed, what user sees, why it matters.
### Phase 2: Structure Tutorial
**Step 4: Plan Sections** (Action-oriented names)
- Section 1: "⚙️ Setup & Install" → Running in 5 minutes
- Section 2: "🚀 First API Call" → Verify it works
- Section 3: "🌐 Core Operations" → Major endpoints
- Section 4: "🐍 SDK Examples" → Language-specific code
- Section 5: "💾 Real Scenario" → Complete workflow
**Step 5: Plan Code Blocks**
- Copy-paste executable curl with real endpoint
- Tabs: cURL → Request Body → Response
- Real data values (names, dates, actual fields)
- Error cases if documented
**Step 6: Plan Workflow**
- Choose actual use case from documentation
- Break into 3-5 sequential API calls
- Show how responses flow into next step
### Phase 3: Implement
**Step 7: For React Artifacts**
Structure:
- Sidebar navigation (6-8 focused sections)
- Main content area with code blocks
- Copy buttons on all code
- Tabbed views (curl/request/response)
**Step 8: Code Block Spec**
- Dark background, language label, copy button
- Left-aligned monospace, syntax highlighting
- No line numbers (confuses copy-paste)
**Step 9: Quality Check** (see checklist at end)
## Tutorial Patterns
### Pattern: API Endpoints
```
TITLE: Endpoint Name (POST /v1/endpoint)
DESCRIPTION: One sentence
CODE BLOCK: Tabs (cURL | Request | Response)
USE CASE: One sentence + real scenario
```
### Pattern: Complete Workflows
```
STEP 1: First API Call
Context (1 sentence) → Code → Result
STEP 2: Second API Call
Context (how previous flows here) → Code → Result
STEP 3: Final Outcome
```
### Pattern: Setup/Installation
```
PREREQUISITES: What they need
COMMAND: Full copy-paste command
VERIFY: One-line check
TROUBLESHOOTING: Common issues
```
### Pattern: SDK Examples
```
LANGUAGE: Python/JavaScript/etc
CODE: Full working function (imports, async/await, error handling)
RUN IT: How to execute
OUTPUT: Expected result
```
### Pattern: Sidebar Navigation
- 6-8 focused sections (not monolithic)
- Emoji + action verbs: "⚙️ Setup", "🚀 First Call"
- Reduces cognitive load, improves completion
### Pattern: Copy Buttons
- One-click copy-to-clipboard (right corner)
- Visual feedback when copied (checkmark, 2 seconds)
- 3x higher code execution rate
### Pattern: Mental Models First
- Present one-sentence model after first working example
- Place in colored box: "💡 How This Works"
- Enables independent problem-solving
### Pattern: Progressive Disclosure
- Section 1: Minimum to get running
- Section 2: Simplest successful request
- Section 3-4: Core operations, multiple languages
- Section 5: Complete multi-step workflow
- Section 6: Advanced features
- Section 7: Troubleshooting
### Pattern: Concrete Use Cases
```
## Common Use Cases
1. **Analytics Dashboard** (5 min read)
You want users to ask "show me Q3 revenue"
→ AI generates interactive chart
2. **Booking Form** (7 min read)
You need booking flow without React
→ AI generates form with calendar
[Pick your use case →]
```
Benefit: Users self-select relevant tutorial path.
### Pattern: Troubleshooting
- Color-coded sections (red=critical, yellow=common)
- For each: Problem → Root cause → Solution → Code
- Include CORS, auth failures, timeouts
## Quality Checklist
**Three Pillars:**
- [ ] Real code (copy-paste executable: curl, Python, JavaScript)
- [ ] Real use cases (3-5 concrete scenarios, not "theoretical")
- [ ] Mental model (one-sentence explanation)
**Code Quality:**
- [ ] Real endpoints (no `<placeholder>`)
- [ ] Real data (Sarah Chen, 2025-11-15, actual field names)
- [ ] Tabs: cURL + Request + Response
- [ ] Left-aligned, properly formatted
**Structure:**
- [ ] First section: Running code in <5 minutes
- [ ] 6-8 focused sections with navigation
- [ ] Complete workflow (form → submit → confirm)
- [ ] Multiple languages (Python, JavaScript, HTTP)
**Content:**
- [ ] Mental model within first 2 examples
- [ ] No conceptual fluff or "learning objectives"
- [ ] Real-world scenario shows data flowing
- [ ] Troubleshooting with real problems
**Interactive (for React artifacts):**
- [ ] Copy buttons on all code
- [ ] Users can complete real task after tutorial
## Real Examples
### Example 1: Mail Command (Markdown)
**Why Markdown:** CLI reference with many commands
**Structure:** Basic Sending → Advanced Options → Interactive Mode → Reading Mail → Configuration → Gmail Integration → Quick Reference
**Key Features:** Copy-paste commands, real config files, organized by workflow
### Example 2: Thesys C1 API (React Artifact)
**Why React:** Complex API needing interactive tabs/navigation
**Structure:** Setup (5min) → First Call → Core Operations → SDK Examples → Real Scenario → Advanced → Troubleshooting
**Key Features:** Sidebar navigation, copy buttons, tabbed views, real data, workflow chaining
## Academic Study Guides: Quote Integration
Same principle applies to academic primary sources (historical documents, philosophical texts, legal cases): transform into practical guide.
### Core Principle
Embed quotes throughout analysis where they support arguments. NOT collected at end.
### Pattern
```
Question → Quote → Interpretation → Quote → Synthesis
NOT: Question → Summary → All Quotes at End
```
### Example
```markdown
## Was Qianlong's Response Wise?
Qianlong defended sovereignty. He explained:
> "If other nations imitate your evil example... how could I possibly comply?"
His reasoning was sound: granting Britain privileges would force him to grant all nations the same.
However, his rejection showed complacency:
> "Strange and costly objects do not interest me."
By dismissing British technology, he missed intelligence-gathering opportunities.
```
### Debate Format
1. Clear position
2. 8-10 numbered arguments (each with quote evidence)
3. Rebuttals section
4. Conclusion
**Each argument:** Claim → Quote → Interpret → Connect to thesis
### Checklist
- [ ] Quotes embedded at point of analysis
- [ ] Every claim supported by quote
- [ ] Each quote followed by interpretation
- [ ] Creates "guide through sources"
## File Organization
**CRITICAL:** All tutorials follow this organization pattern:
### 1. Markdown Tutorials → claude_files/tutorial/
```bash
# Create in project's claude_files/tutorial directory
mkdir -p claude_files/tutorial
# Create tutorial file there
# Example: claude_files/tutorial/youtube-data-api.md
```
**Naming convention:**
- Lowercase, kebab-case
- Descriptive: `{technology}-{purpose}.md`
- Examples: `youtube-data-api.md`, `python-cli-tutorial.md`, `docker-compose-guide.md`
### 2. HTML Tutorials → claude_files/html/
```bash
# Create in project's claude_files/html directory
mkdir -p claude_files/html
# Create HTML file there
# Example: claude_files/html/youtube-data-tutorial.html
```
**Naming convention:**
- Lowercase, kebab-case
- Descriptive: `{technology}-{purpose}.html`
- Examples: `youtube-data-tutorial.html`, `api-comparison.html`
### 3. Why This Pattern?
1. **Project-specific** - Tutorials live with the code they document
2. **Version controlled** - Part of the project, tracked in git
3. **Self-contained** - Everything in `claude_files/` for easy cleanup
4. **Consistent location** - Always `claude_files/tutorial/` or `claude_files/html/`
5. **No symlinks** - Direct files, no complicated linking
### Workflow
When creating a tutorial:
**Markdown:**
1. Run: `mkdir -p claude_files/tutorial`
2. Create: `claude_files/tutorial/{name}.md`
3. Preview: `nvim -c "MarkdownPreview" claude_files/tutorial/{name}.md`
**HTML:**
1. Run: `mkdir -p claude_files/html`
2. Create: `claude_files/html/{name}.html`
3. Open: `open claude_files/html/{name}.html`
## Tools & Preview
**Build:** building-artifacts skill (React + Tailwind + shadcn/ui)
**Format:** Dark code blocks with copy buttons, monospace
**Layout:** Sidebar + main content
**Preview markdown tutorials:**
**CRITICAL:** Always open markdown tutorials with preview immediately after creation.
```bash
nvim -c "MarkdownPreview" /path/to/tutorial.md
```
This provides instant visual feedback and allows the user to review formatting, code blocks, and overall structure in the rendered view.
Use direct commands (no aliases) for reproducibility.

# Documentation Tutorial Skill - Code-First UI & Content Requirements
**Status**: ✅ Updated for Code-First Approach
**Last Updated**: October 2025
**User Feedback**: "I like this much more" - Hands-on, code-first direction confirmed
---
## Executive Summary
The documentation-tutorial skill builds interactive, hands-on tutorials from technical documentation. This document captures the definitive **code-first** UI and content requirements that prioritize executable examples over conceptual explanations.
**Core Philosophy**: Get developers running real code in under 5 minutes. No fluff, no "learning objectives," no conceptual intros. Just code that works.
---
## Content Requirements
### ✅ What MUST Be Included
#### 1. Real, Executable Code Examples
- **Requirement**: All code is copy-paste ready, runs immediately as-is
- **Why**: Developers want to work code first, theory later
- **How to Verify**: Copy any code block, paste into terminal/IDE, it runs
- **Example**: `curl -X POST http://127.0.0.1:8080/v1/memories -H "Content-Type: application/json" -d '{...}'`
#### 2. Actual API Endpoints
- **Requirement**: Use real endpoints from documentation (not `<placeholder>` or `http://localhost:3000`)
- **Why**: Developers need to know exactly which URL to hit
- **How to Verify**: Endpoint matches documentation exactly
- **Example**: `POST /v1/memories` not `POST /memories` or `POST /api/memories`
#### 3. Real Request & Response Payloads
- **Requirement**: Show actual JSON structures from documentation, with real field names and realistic values
- **Why**: Developers copy JSON to understand structure and test immediately
- **How to Verify**: Request/response JSON matches documentation; includes realistic data (names, IDs, field values)
- **Example**:
```json
{
"user_id": "patient_123",
"interaction_type": "symptom_report",
"content": "Patient reported headache and fatigue"
}
```
NOT: `{"user_id": "xxx", "data": "..." }`
#### 4. Action-Oriented Section Names
- **Requirement**: Section titles describe WHAT YOU'LL DO, not what you'll learn
- **Why**: Developers scan for actionable sections, not concepts
- **How to Verify**: Sections use imperative verbs (Setup, Call, API, Implement) not passive nouns (Understanding, Learning, Concepts)
- **Example**: "⚙️ Setup & Install" or "🚀 First API Call" ✓
NOT: "Understanding Installation" or "Learning API Concepts" ✗
#### 5. Quick Start (< 5 minutes)
- **Requirement**: First section gets users to running code in under 5 minutes
- **Why**: Developers evaluate tools by trying them, not reading docs
- **How to Verify**: First section has installation command + one verification curl + success response
- **Example**: Copy command → Run → See response → "It works!"
#### 6. Real-World Workflow Scenarios
- **Requirement**: Show complete workflows with multiple API calls connected
- **Why**: Isolated examples don't show how things actually work together
- **How to Verify**: Workflow shows 3-5 connected API calls; each shows input/output; user can accomplish real task
- **Example**: Store symptom → Search memories → Generate response (healthcare bot example)
#### 7. Step-by-Step API Call Chains
- **Requirement**: For workflows, show how data flows between API calls
- **Why**: Developers need to understand request/response connection, not just isolated calls
- **How to Verify**: Each workflow step shows: Input Data → API Call → Response → Next Step Context
- **Example**:
```
STEP 1: Store User Symptom
POST /v1/memories with patient_id="patient_123"
Response: memory_id="mem_456"
STEP 2: Search Related Memories
GET /v1/search?user_id=patient_123&query="headache"
Response: [related memories...]
STEP 3: Use Results
[Show how results feed into agent response]
```
### ❌ What Must NOT Be Included
- ❌ **Conceptual explanations** - No "Understanding X" sections (max 1 paragraph if necessary)
- ❌ **Learning objectives** - No "After this section you'll understand..."
- ❌ **Key takeaways checklists** - No "What you learned" sections
- ❌ **Placeholder syntax** - No `<endpoint>` or `{value}` - use actual values
- ❌ **Simplified code examples** - Show actual code from docs, not "clean" versions
- ❌ **High-level summaries** - Never paraphrase; show real code instead
- ❌ **Theoretical scenarios** - Only real use cases from documentation

## Examples of What Works (Code-First)
### ✅ Good Section Title
```
⚙️ Setup & Install
🚀 First API Call
🌐 REST API (All Endpoints)
🐍 Python SDK Examples
💾 Real Scenario: Healthcare Bot
```
### ✅ Good Code Block (Copy-Paste Ready)
```bash
curl -X POST http://127.0.0.1:8080/v1/memories \
-H "Content-Type: application/json" \
-H "Authorization: Bearer your-api-key" \
-d '{
"user_id": "patient_123",
"interaction_type": "symptom_report",
"content": "Patient reported headache and fatigue"
}'
```
(Exact from documentation, immediately runnable)
### ✅ Good API Example (Tabs)
```
[cURL Tab] - Full curl command, copy-paste ready
[Request Tab] - Complete JSON, all fields
[Response Tab] - Real response from docs, shows what you'll get
```
### ✅ Good Real-World Workflow
```
STEP 1: Store Symptom
Command: curl POST /memories with symptom data
Response: memory_id, timestamp
STEP 2: Search Related
Command: curl GET /search with memory_id
Response: array of related memories
STEP 3: Generate Response
Command: Use results in LLM prompt
Result: Healthcare agent responds with relevant history
```
### ✅ Good Info Card
```
Endpoint: POST /v1/memories
HTTP Method: POST
Required Auth: API Key in header
Response: 200 OK with memory_id
Use: Store user interaction for later recall
```
---
## Examples of What Doesn't Work (Avoid!)
### ❌ Bad Section Title (Conceptual)
```
Learning About Setup
Understanding API Concepts
Key Concepts in REST
```
### ❌ Bad Code Block (Placeholder/Simplified)
```
memory = Memory() # Simplified example
memory.store({"data": "..."}) # Use actual field names!
curl -X POST <endpoint> -d '<json>' # Needs actual endpoint and JSON
```
### ❌ Bad Learning Objective Box
```
After this section, you'll understand:
- What an API endpoint is
- How request/response works
- How to use the REST API
```
### ❌ Bad "Key Takeaways"
```
☐ Concept 1: You learned what memory storage is
☐ Concept 2: How the API works
☐ Concept 3: When to use memories
```
### ❌ Bad Workflow (Isolated Endpoints)
```
POST /v1/memories with data
GET /v1/memories/id
DELETE /v1/memories/id
[Each shown separately, no connection shown]
```
---

name: "gmail-assistant"
description: "Use when composing, sending, searching, or managing Warren's emails via gmail CLI. Covers drafting with styles, finding similar emails for context, managing groups, discovering contacts online, and email workflows. Always test to fuchengwarrenzhu@gmail.com before real sends."
---
# Gmail Assistant
Use this skill when working with email through the `gmail` CLI tool.
## Quick Commands
- `/gmail` - Quick reference for common gmail CLI commands
- `/gmail::setup` - Set up Gmail CLI authentication
## Core Principles
**ALWAYS before composing:**
1. Search past emails to recipient(s) → extract patterns (greeting, tone, sign-off)
2. Check available email styles → match context
3. Test to fuchengwarrenzhu@gmail.com FIRST
4. Review preview → then send to real recipient
**Progressive disclosure:**
- Start with summaries (`gmail list`, `gmail search`)
- Read full content only when needed (`--full`)
- Get thread context only if required (`gmail thread`)
---
## Essential Commands
### Search & Discovery
```bash
gmail search "to:person@example.com" --max 10 # Emails to someone
gmail search "from:person@example.com" --max 10 # Emails from someone
gmail search "subject:keyword after:2024/10/01" # By subject + date
gmail search "has:attachment filename:pdf" # With attachments
gmail list --folder INBOX --max 10 # List inbox
gmail folders # List all folders/labels
```
### Read & View
```bash
gmail read <message_id> # Summary view
gmail read <message_id> --full # Full content
gmail read <message_id> --full-thread # Full content with thread context
gmail thread <message_id> # View entire thread
gmail thread <message_id> --strip-quotes # View thread without quoted content
```
### Send & Reply
```bash
# Send from file (preferred for composed emails)
gmail send --to user@example.com --subject "X" --body "$(cat /tmp/email/draft.txt)"
gmail send --to user@example.com --subject "X" --body "$(cat /tmp/email/draft.txt)" --attachment file.pdf
# Send inline (for quick replies only)
gmail send --to user@example.com --subject "X" --body "Y"
gmail reply <message_id> --body "Reply text"
gmail reply <message_id> --body "Reply" --reply-all
```
### Email Styles
```bash
gmail styles list # List all styles
gmail styles show professional-formal # View specific style
gmail styles validate style-name # Validate format
```
**Common styles:** `professional-formal`, `professional-friendly`, `casual-friend`, `brief-reply`
### Email Groups
```bash
gmail groups list # List all groups
gmail groups show team # Show group members
gmail groups add team person@example.com # Add member
gmail send --to @team --subject "X" --body "Y" # Use group
```
### Workflows
```bash
gmail workflows list # List workflows
gmail workflows run clear # Run interactively
gmail workflows start clear # Start programmatic (JSON)
gmail workflows continue <token> archive # Continue with action
```
---
## Important Workflow Guidelines
### Composing Emails
1. Search past emails to recipient → extract greeting/tone/sign-off patterns
2. Check relevant email styles (`gmail styles list`)
3. Draft combining past patterns + style + current context
4. **Write draft to `/tmp/email/{descriptive_name}.txt`**
5. Open file for user review/editing (use `open` command on macOS)
6. **Test to fuchengwarrenzhu@gmail.com first** using file: `gmail send --to fuchengwarrenzhu@gmail.com --subject "..." --body "$(cat /tmp/email/{name}.txt)" --yolo`
7. After user confirms, send to real recipient using same file
### Extracting Email Style from Past Emails
1. Search relevant past emails: `gmail search "to:@harvard.edu" --folder SENT --max 10`
2. Read full content: `gmail read <message_id> --full`
3. Note patterns:
- **Greeting**: Formal (Dear Professor) vs. casual (Hi)
- **Tone**: Professional, friendly, concise
- **Structure**: Sections (Why/Preparation/Commitment), bullet points, paragraphs
- **Sign-off**: Best regards, Thanks, etc.
- **Signature**: Contact info format
4. Match these patterns in new draft for consistency
### Replying to Emails
1. Read original email (`gmail read <id> --full`)
2. Check thread if needed (`gmail thread <id>`)
3. Search past emails from sender to match their style
4. Draft appropriate reply → review preview → send
### Finding Contacts
1. Search inbox: `gmail search "from:[name]"`
2. Search sent: `gmail search "to:[name]"`
3. Check groups: `gmail groups list`
4. If not found → search web (LinkedIn, org directories)
5. Confirm with user before using new emails
---
## Extracting Email Context
### Getting Full Thread Conversation
**Recommended approach:**
```bash
# Use gmail thread to view entire conversation
gmail thread <message_id> # Show full thread
gmail thread <message_id> --strip-quotes # Remove quoted content for clarity
gmail thread <message_id> --output-format json # Get JSON format
```
**Alternative (manual assembly):**
```bash
# 1. Find thread
gmail list --folder ALL --query "keyword"
# 2. Get all message IDs in thread
# Note thread_id from results
# 3. Read each message with full body
gmail read <id> --full
# 4. Piece together conversation manually
```
### Finding CC'd Recipients
If `gmail read` output doesn't show CC/BCC recipients (current limitation), use Python workaround:
```python
from gmaillm.gmail_client import GmailClient
client = GmailClient()
msg = client.service.users().messages().get(
userId='me',
id='<message_id>',
format='full'
).execute()
headers = msg['payload']['headers']
# Extract CC recipients
cc = [h['value'] for h in headers if h['name'].lower() == 'cc']
to = [h['value'] for h in headers if h['name'].lower() == 'to']
from_ = [h['value'] for h in headers if h['name'].lower() == 'from']
print(f"From: {from_}")
print(f"To: {to}")
print(f"CC: {cc}")
```
### Common Pattern: Draft Reply Based on Thread
**Complete workflow:**
1. Search for thread: `gmail list --folder ALL --query "subject:keywords"`
2. Note message IDs and thread_id from results
3. Read each message for context: `gmail read <id>` (or `--full` for body)
4. Extract who's involved:
- If CC not visible, use Python workaround above
- Note all participants from From/To/CC fields
5. Draft reply matching tone and context
6. Include appropriate recipients (reply vs reply-all)
7. Send with `--yolo` to skip confirmation
**Example:**
```bash
# Find thread
gmail list --folder ALL --query "MLD courses" --output-format json
# Read messages
gmail read 19a5a90f97be8df8
# Extract CC (if needed)
# Use Python script above
# Send reply with CC
gmail send --to "mksmith@hks.harvard.edu" --cc "Greg_Dorchak@hks.harvard.edu" --subject "Reply" --body "..." --yolo
```
---
## Gmail Search Operators
**People:** `from:`, `to:`, `cc:`, `bcc:`
**Date:** `after:YYYY/MM/DD`, `before:YYYY/MM/DD`, `newer_than:7d`, `older_than:30d`
**Status:** `is:unread`, `is:starred`, `is:important`, `is:read`
**Content:** `subject:keyword`, `has:attachment`, `has:drive`, `filename:pdf`
**Size:** `larger:10M`, `smaller:5M`
**Boolean:** `OR`, `-` (NOT), `()` (grouping)
**Examples:**
- All correspondence: `to:person@example.com OR from:person@example.com`
- Recent thread: `subject:project after:2024/10/01`
- Unread important: `is:unread is:important`
- With PDF: `has:attachment filename:pdf`
---
## Key Things to Know
**Email Styles:**
- Located in `~/.gmaillm/email-styles/`
- Common: `professional-formal`, `professional-friendly`, `casual-friend`, `brief-reply`
- View with `gmail styles show <name>`
- Use for guidance on tone, greetings, closings
**Configuration:**
- All settings in `~/.gmaillm/`
- First time: `gmail setup-auth`
- Verify: `gmail verify`
**Best Practices:**
- Search past emails before composing → extract patterns
- Use progressive disclosure → summaries first, full content only when needed
- Test to fuchengwarrenzhu@gmail.com before real sends
- Leverage email groups for recurring distributions
- Match recipient's formality level
**Common Mistakes to Avoid:**
- Sending without searching first
- Wrong formality level (too casual or too formal)
- Skipping test emails
- Not using groups for recurring sends
- Getting full email when summary sufficient

## Quick Reference Card
### Python Library Cheat Sheet
```python
from gmaillm import GmailClient, SendEmailRequest
client = GmailClient()
# List
result = client.list_emails(folder='INBOX', max_results=10)
# Read
email = client.read_email(msg_id, format="summary")
email = client.read_email(msg_id, format="full")
# Search
result = client.search_emails("from:user@example.com has:attachment")
# Thread
thread = client.get_thread(msg_id)
# Send
request = SendEmailRequest(to=["user@example.com"], subject="Hi", body="Hello")

# Reply
response = client.reply_email(msg_id, body="Thanks!", reply_all=False)
# Labels
client.modify_labels(msg_id, add_labels=['STARRED'], remove_labels=['UNREAD'])
```
### CLI Cheat Sheet
```bash
gmail verify # Check setup
gmail list --folder INBOX --max 10 # List emails
gmail read <id> --full # Read email
gmail thread <id> # View conversation
gmail search "is:unread" --max 20 # Search

## Authentication
Uses existing Gmail MCP OAuth2 credentials:
- **Credentials:** `/Users/wz/.gmail-mcp/credentials.json`
- **OAuth Keys:** `/Users/wz/Desktop/OAuth2/gcp-oauth.keys.json`
Tokens auto-refresh. If authentication fails:
1. Check credential files exist
2. Verify OAuth tokens not expired
3. Run `gmail verify` to diagnose
---
## Common Patterns
### Progressive Disclosure
```python
# Always start with summary
summaries = client.list_emails(max_results=10)
# Only get full content when needed
for summary in summaries.emails:
if "important keyword" in summary.subject.lower():
full = client.read_email(summary.message_id, format="full")
# Process full email
```
### Pagination
```python
all_emails = []
page_token = None
while True:
result = client.list_emails(max_results=50, page_token=page_token)
all_emails.extend(result.emails)
if not result.next_page_token:
break
page_token = result.next_page_token
```
### Error Handling
```python
try:
response = client.send_email(request)
if response.success:
print(f"Sent: {response.message_id}")
else:
print(f"Failed: {response.error}")
except RuntimeError as e:
print(f"Error: {e}")
```

## Validation Rules
The `StyleLinter` enforces these rules:
### YAML Frontmatter
- ✓ Required fields: `name`, `description`
- ✓ Name length: 3-50 characters
- ✓ Description: 30-200 characters
- ✓ Description must start with "When to use:"
- ✓ No extra fields
### XML Sections
- ✓ All 6 sections present
- ✓ Correct order: examples → greeting → body → closing → do → dont
- ✓ Proper opening/closing tags
- ✓ Non-empty content
### Formatting
- ✓ No trailing whitespace
- ✓ List items: `- ` (dash + space)
- ✓ Minimum items: examples (1), do (2), dont (2)
### Auto-Fix Capabilities
The `--fix` flag can automatically correct:
- Trailing whitespace
- List item spacing (`-item` → `- item`)
- Extra blank lines
**Cannot auto-fix:**
- Missing sections
- Wrong section order
- Invalid frontmatter
- Empty sections
## Creating a New Style
### Step 1: Create Template
```bash
gmail styles create my-custom-style
```
This creates `~/.gmaillm/email-styles/my-custom-style.md` with template structure.
### Step 2: Edit in Your Editor
The command automatically opens the file in your default editor (determined by `$EDITOR` environment variable).
### Step 3: Fill In Content
Replace template placeholders with your content:
1. **Update frontmatter** - Set name and description
2. **Add examples** - Write 1-3 complete email examples
3. **Define greeting patterns** - Specify greeting guidelines
4. **Define body guidelines** - Specify writing rules
5. **Define closing patterns** - Specify closing guidelines
6. **List do's** - Best practices (minimum 2)
7. **List dont's** - Things to avoid (minimum 2)
### Step 4: Validate
```bash
gmail styles validate my-custom-style
```
Fix any errors shown.
### Step 5: Use
```bash
gmail styles show my-custom-style
```
## Common Validation Errors
### "Description must start with 'When to use:'"
**Problem**: Description doesn't have required prefix.
**Fix**:
```yaml
# Wrong
description: "For casual emails to friends"
# Correct
description: "When to use: Casual emails to friends and close colleagues."
```
### "Sections must appear in strict order"
**Problem**: Sections are out of order.
**Fix**: Reorder sections to match: examples → greeting → body → closing → do → dont
### "Missing required section"
**Problem**: One or more sections are missing.
**Fix**: Add all 6 required sections with proper tags.
### "List items must start with '- '"
**Problem**: List items have incorrect formatting.
**Fix**:
```markdown
# Wrong
<do>
-Item 1
* Item 2
</do>
# Correct
<do>
- Item 1
- Item 2
</do>
```
## Tips for Good Styles
1. **Be specific** - "Use first name only" not "Be casual"
2. **Show examples** - Real email examples are most helpful
3. **Keep it concise** - Shorter guidelines are easier to follow
4. **Test it** - Use the style for real emails and refine
5. **Version control** - Styles are just text files, commit them to git
## File Location
All styles are stored in:
```
~/.gmaillm/email-styles/
├── professional-formal.md
├── professional-friendly.md
├── academic.md
├── casual-friend.md
├── brief-update.md
└── my-custom-style.md
```
## Built-in Styles
gmaillm includes 5 professional styles:
1. **professional-formal** - Executives, legal, formal outreach
2. **professional-friendly** - Colleagues, known contacts
3. **academic** - Faculty, academic collaborators
4. **casual-friend** - Friends, informal communication

- `UNREAD` - Unread
- `CATEGORY_PERSONAL` - Personal category
- `CATEGORY_SOCIAL` - Social category
- `CATEGORY_PROMOTIONS` - Promotions category
- `CATEGORY_UPDATES` - Updates category
- `CATEGORY_FORUMS` - Forums category
**Examples:**
```bash
# Emails in inbox
gmail search "label:inbox" --max 20
# Archived emails (not in inbox)
gmail search "-label:inbox" --max 20
# Sent emails
gmail search "label:sent" --max 10
# Custom label
gmail search "label:work" --max 20
```
---
## Boolean Operators
### AND (implicit)
```
keyword1 keyword2 # Both keywords (space = AND)
keyword1 AND keyword2 # Explicit AND
```
**Examples:**
```bash
# Both keywords
gmail search "project deadline" --max 10
# Explicit AND
gmail search "project AND deadline" --max 10
```
### OR
```
keyword1 OR keyword2 # Either keyword
```
**Examples:**
```bash
# Emails from either person
gmail search "from:alice@example.com OR from:bob@example.com" --max 10
# Multiple subjects
gmail search "subject:meeting OR subject:schedule" --max 10
```
### NOT (-)
```
-keyword # Does NOT contain keyword
-operator:value # Does NOT match operator
```
**Examples:**
```bash
# Exclude sender
gmail search "subject:report -from:manager@company.com" --max 10
# Not in inbox (archived)
gmail search "-label:inbox" --max 20
# Not read
gmail search "-is:read" --max 10
```
### Grouping ( )
```
(condition1 OR condition2) # Group conditions
```
**Examples:**
```bash
# Emails from alice OR bob with attachments
gmail search "(from:alice OR from:bob) has:attachment" --max 10
# Multiple subjects with specific date range
gmail search "(subject:meeting OR subject:schedule) after:2024/10/01" --max 20
```
---
## Thread Operators
```
in:thread_id # Emails in specific thread
```
**Example:**
```bash
# Get all emails in a thread (use thread_id from email details)
gmail search "in:19abc123def456" --max 20
```
---
## Wildcard Operator
```
* # Wildcard (limited use in Gmail)
```
**Note:** Gmail's wildcard support is limited. It works best with:
- Email addresses: `from:*@example.com`
- Not recommended for general text searches
---
## Common Search Patterns
### Workflow-Specific Searches
#### Before Composing to Someone
Find all correspondence (sent + received):
```bash
gmail search "to:person@example.com OR from:person@example.com" --max 10
```
#### Finding Unread Important Emails
```bash
gmail search "is:unread is:important" --max 20
```
#### Recent Emails About a Topic
```bash
gmail search "subject:project-name newer_than:30d" --max 10
```
#### Emails from Team with Attachments
```bash
gmail search "(from:alice@team.com OR from:bob@team.com) has:attachment" --max 10
```
#### Large Emails to Clean Up
```bash
gmail search "larger:10M older_than:1y" --max 20
```
#### Unanswered Emails
```bash
gmail search "is:unread from:important@person.com newer_than:7d" --max 10
```
---
## Advanced Search Patterns
### Finding Email Threads
Search for initial email and use thread view:
```bash
# Find thread starter
gmail search "subject:keyword from:person@example.com" --max 5
# Then use thread command
gmail thread <message_id>
```
### Combining Multiple Criteria
```bash
# Complex search: unread emails from professor with attachments in last 30 days
gmail search "from:professor@edu.edu is:unread has:attachment newer_than:30d" --max 10
# Emails from multiple people about specific topic
gmail search "(from:alice OR from:bob) subject:budget newer_than:7d" --max 10
```
### Excluding Common Patterns
```bash
# Important emails excluding automated notifications
gmail search "is:important -from:noreply -from:no-reply" --max 20
# Emails with attachments excluding newsletters
gmail search "has:attachment -label:promotions" --max 20
```
---
## Search Best Practices
### 1. Start Broad, Then Refine
```bash
# Start broad
gmail search "project" --max 20
# Refine
gmail search "project from:alice@example.com" --max 10
# Further refine
gmail search "project from:alice@example.com after:2024/10/01" --max 5
```
### 2. Use Date Ranges for Context
```bash
# Recent context (last 7 days)
gmail search "to:person@example.com newer_than:7d" --max 5
# Historical context (last 6 months)
gmail search "to:person@example.com newer_than:6m" --max 20
```
### 3. Combine Sender and Recipient
```bash
# All correspondence with someone
gmail search "to:person@example.com OR from:person@example.com" --max 10
```
### 4. Use Labels for Organization
```bash
# Search within labeled emails
gmail search "label:work subject:report" --max 10
# Exclude certain labels
gmail search "has:attachment -label:spam -label:trash" --max 20
```
---
## CLI-Specific Options
### Max Results
```bash
# Limit results (1-50)
gmail search "query" --max 10
gmail search "query" --max 20
gmail search "query" --max 50
```
### Folder Filtering
```bash
# Search within specific folder
gmail search "is:unread" --folder INBOX --max 10
gmail search "keyword" --folder SENT --max 20
```
---
## Common Mistakes
### 1. Not Quoting Phrases
**Wrong:**
```bash
gmail search "subject:meeting notes" # Searches for subject:meeting AND notes anywhere
```
**Right:**
```bash
gmail search 'subject:"meeting notes"' # Searches for exact phrase in subject
```
### 2. Forgetting OR is Uppercase
**Wrong:**
```bash
gmail search "from:alice or from:bob" # "or" treated as keyword
```
**Right:**
```bash
gmail search "from:alice OR from:bob" # OR is operator
```
### 3. Using Wildcards for General Text
**Wrong:**
```bash
gmail search "meet*" # Limited wildcard support
```
**Right:**
```bash
gmail search "meeting" # Use complete words
```
### 4. Not Using Parentheses for Complex Queries
**Wrong:**
```bash
gmail search "from:alice OR from:bob has:attachment" # Ambiguous
```
**Right:**
```bash
gmail search "(from:alice OR from:bob) has:attachment" # Clear grouping
```

## Testing Searches
Always test searches with small result sets first:
```bash
# Test with --max 5 first
gmail search "complex query here" --max 5
# If results look good, increase
gmail search "complex query here" --max 20
```
---
## Pagination
For large result sets, use pagination:
```bash
# Get first page
gmail search "query" --max 50
# Use next_page_token from results for subsequent pages
# (Python API supports this; CLI shows truncated results)
```

## Gmail Query Syntax
Common Gmail search operators:
| Operator | Example | Description |
|----------|---------|-------------|
| `from:` | `from:alice@example.com` | Emails from sender |
| `to:` | `to:bob@example.com` | Emails to recipient |
| `subject:` | `subject:meeting` | Subject contains word |
| `is:unread` | `is:unread` | Unread emails |
| `is:read` | `is:read` | Read emails |
| `has:attachment` | `has:attachment` | Has attachments |
| `label:` | `label:important` | Has label |
| `after:` | `after:2025/01/01` | After date (YYYY/MM/DD) |
| `before:` | `before:2025/12/31` | Before date |

| `older_than:` | `older_than:1m` | Older than N time |
| `OR` | `from:alice OR from:bob` | Either condition |
| `-` | `-label:spam` | Exclude (NOT) |
**Combine operators:**
```bash
gmail search "from:boss subject:urgent is:unread"
```
## Email Style Format
Email styles use YAML frontmatter + XML-like sections:
```markdown
---
name: "style-name"
description: "When to use: Context description (30-200 chars)."
---
<examples>
Example 1
---
Example 2
</examples>
<greeting>
- "Hi [Name],"
</greeting>
<body>
- Guideline 1
- Guideline 2
</body>
<closing>
- "Best,"
</closing>
<do>
- Best practice 1
</do>
<dont>
- What to avoid
</dont>
```
Required sections in strict order: examples → greeting → body → closing → do → dont
## Common Email Workflows
### 1. Research + Draft + Send
```bash
# Search for similar emails
gmail search "subject:similar topic" --max 3
# Read one for context
gmail read <message_id> --full
# Check style
gmail styles show professional-formal
# TEST first
gmail send --to fuchengwarrenzhu@gmail.com --subject "[TEST] ..." --body "..."
# Send for real
gmail send --to real@email.com --subject "..." --body "..." --yolo
```
### 2. Bulk Processing with Workflow
```bash
# Create workflow for common query
gmail workflows create \
--id "newsletter-cleanup" \
--name "Clean Up Newsletters" \
--query "label:newsletters is:read older_than:30d"
# Run workflow
gmail workflows run newsletter-cleanup
```
### 3. Group Broadcast
```bash
# Verify group
gmail groups show "#team"
# Check style
gmail styles show posts
# TEST
gmail send --to fuchengwarrenzhu@gmail.com --subject "[TEST] Update" --body "..."
# Broadcast
gmail send --to "#team" --subject "Update" --body "..." --yolo
```
## Status and Configuration
### Check Account Status
```bash
gmail status
```
### Verify Authentication
```bash
gmail verify
```
### Show Configuration
```bash
gmail config show
```
### List Labels
```bash
gmail labels list
```
## JSON Output for Automation
All commands support `--output-format json` for programmatic parsing:
```bash
# Get JSON for parsing
gmail search "is:unread" --output-format json | jq '.emails[] | {from: .from_.email, subject: .subject}'
# List groups in JSON
gmail groups list --output-format json
# Read email as JSON
gmail read <message_id> --output-format json
```
## Common Gotchas
1. **Email IDs**: Displayed short (12 chars) but use full ID in commands
2. **Group prefix**: Always use `#` prefix (e.g., `#team` not `team`)
3. **YOLO flag**: Skips confirmation, use after testing
4. **Date format**: Use YYYY/MM/DD for Gmail queries
5. **Test emails**: ALWAYS test to fuchengwarrenzhu@gmail.com first
6. **Style order**: Sections must be in exact order (examples, greeting, body, closing, do, dont)
7. **Attachment paths**: Use absolute or relative file paths, comma-separated

name: google-drive
description: Interact with Google Drive API using PyDrive2 for uploading, downloading, searching, and managing files. Use when working with Google Drive operations including file transfers, metadata queries, search operations, folder management, batch operations, and sharing. Authentication is pre-configured at ~/.gdrivelm/. Includes helper scripts for common operations and comprehensive API references. Helper script automatically detects markdown formatting and sets appropriate MIME types.
---
## Configuration
**Helper script path:**
```
/Users/wz/.claude/plugins/marketplaces/warren-claude-code-plugin-marketplace/claude-context-orchestrator/skills/google-drive/scripts/gdrive_helper.py
```
**Authentication files** (use `~/.gdrivelm/` - expands to home directory):
- Credentials: `~/.gdrivelm/credentials.json`
- Settings: `~/.gdrivelm/settings.yaml`
- Token: `~/.gdrivelm/token.json` (auto-generated)
Load `references/auth_setup.md` for detailed authentication configuration.
## Helper Script Usage
Use `scripts/gdrive_helper.py` for common operations to avoid rewriting authentication and upload/download code.
### Import and Use Functions
```python
import sys
sys.path.insert(0, '/Users/wz/.claude/plugins/marketplaces/warren-claude-code-plugin-marketplace/claude-context-orchestrator/skills/google-drive/scripts')
from gdrive_helper import authenticate, upload_file, download_file, search_files, get_metadata
# Authenticate once
drive = authenticate()
# Upload file
result = upload_file(drive, '/path/to/file.txt', title='My File')
print(f"Uploaded: {result['id']}")
# Search files
results = search_files(drive, "title contains 'report'")
for file in results:
print(f"{file['title']} - {file['id']}")
# Download file
download_file(drive, 'FILE_ID', '/path/to/save.txt')
# Get metadata
metadata = get_metadata(drive, 'FILE_ID')
print(f"Size: {metadata['size']} bytes")
```
### Available Helper Functions
- `authenticate()` - Authenticate and return Drive instance
- `upload_file(drive, local_path, title=None, folder_id=None)` - Upload local file
- `upload_string(drive, content, title, folder_id=None, use_markdown=None)` - Upload string content with auto-markdown detection
- `download_file(drive, file_id, local_path)` - Download file
- `get_file_content(drive, file_id)` - Get file content as string
- `get_metadata(drive, file_id)` - Get file metadata
- `search_files(drive, query, max_results=None)` - Search for files
- `delete_file(drive, file_id, permanent=False)` - Delete or trash file
- `create_folder(drive, folder_name, parent_id=None)` - Create folder
- `list_files_in_folder(drive, folder_id)` - List files in folder
### CLI Usage
The helper script can also be used from command line:
```bash
# Activate environment first
cd ~/Desktop/zPersonalProjects/gdrivelm
source venv/bin/activate
# Run commands
python ~/.claude/plugins/marketplaces/warren-claude-code-plugin-marketplace/claude-context-orchestrator/skills/google-drive/scripts/gdrive_helper.py upload /path/to/file.txt
python ~/.claude/plugins/marketplaces/warren-claude-code-plugin-marketplace/claude-context-orchestrator/skills/google-drive/scripts/gdrive_helper.py search "title contains 'report'"
python ~/.claude/plugins/marketplaces/warren-claude-code-plugin-marketplace/claude-context-orchestrator/skills/google-drive/scripts/gdrive_helper.py download FILE_ID /path/to/save.txt
```
## File Type Handling
Google Drive files require different retrieval methods depending on their type:
### Google Docs/Sheets/Slides (Native Google Formats)
Native Google formats require **export** with a specific MIME type, not direct download:
```python
import sys
sys.path.insert(0, '/Users/wz/.claude/plugins/marketplaces/warren-claude-code-plugin-marketplace/claude-context-orchestrator/skills/google-drive/scripts')
from gdrive_helper import authenticate
drive = authenticate()
# Extract file ID from URL
file_id = '1rX7KHFnHyoAu3KrIvQgv0gJdTvMztWJT-Pkx5x954vc'
# Create file object and fetch metadata
file = drive.CreateFile({'id': file_id})
file.FetchMetadata()
# Export with appropriate MIME type
content = file.GetContentString(mimetype='text/plain') # For Google Docs
# content = file.GetContentString(mimetype='text/csv') # For Google Sheets
# content = file.GetContentString(mimetype='text/plain') # For Google Slides
print(content)
```
### Regular Files (PDF, Images, Text, etc.)
Regular uploaded files can use direct download:
```python
from gdrive_helper import authenticate, get_file_content
drive = authenticate()
content = get_file_content(drive, 'FILE_ID')
```
### Usage Pattern: No Project Directory Required
**Important:** The helper scripts are globally available. You don't need to `cd` into a project directory:
```python
# ✅ CORRECT: Import from global skill path directly
import sys
sys.path.insert(0, '/Users/wz/.claude/plugins/marketplaces/warren-claude-code-plugin-marketplace/claude-context-orchestrator/skills/google-drive/scripts')
from gdrive_helper import authenticate
drive = authenticate()
# Continue with operations...
# ❌ INCORRECT: Don't try to cd into project directory
# cd ~/Desktop/zPersonalProjects/gdrivelm # This may not exist
```
## Common Operations
### Upload File from Local Path
```python
from gdrive_helper import authenticate, upload_file
drive = authenticate()
result = upload_file(drive, '/path/to/document.pdf', title='Important Document')
print(f"File ID: {result['id']}")
print(f"Link: {result['link']}")
```
### Upload String Content
The `upload_string` function automatically detects markdown formatting and sets the appropriate MIME type:
```python
from gdrive_helper import authenticate, upload_string
drive = authenticate()
# Auto-detects markdown based on content
markdown_content = """# My Document
This is a **markdown** formatted document with:
- Lists
- **Bold** text
- [Links](https://example.com)
"""
result = upload_string(drive, markdown_content, 'My Document')
print(f"Created: {result['title']}") # Will be 'My Document.md'
print(f"MIME Type: {result['mimeType']}") # Will be 'text/markdown'
# Force plain text (disable auto-detection)
plain_content = "This is plain text content"
result = upload_string(drive, plain_content, 'note.txt', use_markdown=False)
# Force markdown
result = upload_string(drive, "Simple text", 'doc', use_markdown=True) # Will be 'doc.md'
```
### Search Files
```python
from gdrive_helper import authenticate, search_files
drive = authenticate()
# Search by title
results = search_files(drive, "title contains 'invoice'")
# Search by type
results = search_files(drive, "mimeType = 'application/pdf'")
# Complex search
query = "title contains 'report' and mimeType = 'application/pdf' and trashed = false"
results = search_files(drive, query)
for file in results:
print(f"{file['title']} ({file['id']})")
```
For comprehensive search query syntax and examples, load `references/search_queries.md`.
### Download File
```python
from gdrive_helper import authenticate, download_file
drive = authenticate()
result = download_file(drive, 'FILE_ID_HERE', '/path/to/save/file.txt')
print(f"Downloaded {result['title']} to {result['local_path']}")
```
### Get File Metadata
```python
from gdrive_helper import authenticate, get_metadata
drive = authenticate()
metadata = get_metadata(drive, 'FILE_ID_HERE')
print(f"Title: {metadata['title']}")
print(f"Size: {metadata['size']} bytes")
print(f"Modified: {metadata['modified']}")
print(f"Link: {metadata['link']}")
```
### Create Folder and Upload to It
```python
from gdrive_helper import authenticate, create_folder, upload_file
drive = authenticate()
# Create folder
folder = create_folder(drive, 'My Documents')
print(f"Folder ID: {folder['id']}")
# Upload file to folder
result = upload_file(drive, '/path/to/file.txt', folder_id=folder['id'])
print(f"Uploaded to folder: {result['title']}")
```
## Advanced Usage
For direct PyDrive2 API usage and advanced features, load `references/api_reference.md`.
### Manual Authentication Pattern
If not using the helper script:
```python
from pydrive2.auth import GoogleAuth
from pydrive2.drive import GoogleDrive
gauth = GoogleAuth(settings_file='/Users/wz/.gdrivelm/settings.yaml')
gauth.LoadCredentialsFile('/Users/wz/.gdrivelm/token.json')
if gauth.credentials is None:
gauth.LocalWebserverAuth()
elif gauth.access_token_expired:
gauth.Refresh()
else:
gauth.Authorize()
gauth.SaveCredentialsFile('/Users/wz/.gdrivelm/token.json')
drive = GoogleDrive(gauth)
```
### Batch Operations
```python
from gdrive_helper import authenticate, upload_file
drive = authenticate()
files = [
'/path/to/file1.txt',
'/path/to/file2.pdf',
'/path/to/file3.docx'
]
for file_path in files:
result = upload_file(drive, file_path)
print(f"Uploaded: {result['title']} ({result['id']})")
```
## Search Query Patterns
Common search patterns (load `references/search_queries.md` for complete syntax):
- `title contains 'text'` - Files with title containing text
- `mimeType = 'application/pdf'` - PDF files only
- `'root' in parents` - Files in root directory
- `trashed = false` - Not in trash
- `'me' in owners` - Files you own
- `modifiedDate > '2024-01-01'` - Modified after date
- `fullText contains 'keyword'` - Search file content
Combine with `and`/`or`:
```python
query = "title contains 'report' and mimeType = 'application/pdf' and trashed = false"
```
## Bundled Resources
### Scripts
- `scripts/gdrive_helper.py` - Reusable Python functions for all common operations
### References
- `references/auth_setup.md` - Complete authentication configuration guide
- `references/search_queries.md` - Comprehensive search query syntax and examples
- `references/api_reference.md` - PyDrive2 API method reference with examples
### Assets
- `assets/settings_template.yaml` - Template PyDrive2 settings file
## Workflow Guidelines
1. **Always activate the virtual environment first** before running any Google Drive code
2. **Use the helper script** for common operations to avoid rewriting code
3. **Load reference files as needed** for detailed syntax and advanced features
4. **Test with small operations first** before batch processing
5. **Check file IDs** when downloading or modifying files
## Error Handling
```python
from pydrive2.files import ApiRequestError
from gdrive_helper import authenticate, get_metadata
drive = authenticate()
try:
metadata = get_metadata(drive, 'FILE_ID')
print(metadata['title'])
except ApiRequestError as e:
if e.error['code'] == 404:
print("File not found")
elif e.error['code'] == 403:
print("Permission denied")
else:
print(f"API Error: {e}")
except Exception as e:
print(f"Error: {e}")
```
## Common Pitfalls
### Pitfall 1: FileNotDownloadableError with Google Docs
**Error Message:**
```
pydrive2.files.FileNotDownloadableError: No downloadLink/exportLinks for mimetype found in metadata
```
**Cause:** Using `get_file_content()` or direct download methods on native Google formats (Docs, Sheets, Slides).
**Solution:** Use `GetContentString(mimetype='...')` to export the file:
```python
# ❌ WRONG: This fails for Google Docs
from gdrive_helper import get_file_content
content = get_file_content(drive, 'GOOGLE_DOC_ID')
# ✅ CORRECT: Export with MIME type
file = drive.CreateFile({'id': 'GOOGLE_DOC_ID'})
file.FetchMetadata()
content = file.GetContentString(mimetype='text/plain')
```
### Pitfall 2: Hardcoded Project Paths
**Error Message:**
```
cd: no such file or directory: /Users/wz/Desktop/zPersonalProjects/gdrivelm
```
**Cause:** Assuming the gdrivelm project directory exists in a specific location.
**Solution:** Import from the global skill path directly (no `cd` required):
```python
# ✅ CORRECT: Works from any directory
import sys
sys.path.insert(0, '/Users/wz/.claude/plugins/marketplaces/warren-claude-code-plugin-marketplace/claude-context-orchestrator/skills/google-drive/scripts')
from gdrive_helper import authenticate
# ❌ WRONG: Don't rely on project directory
# cd ~/Desktop/zPersonalProjects/gdrivelm && source venv/bin/activate
```
### Pitfall 3: Extracting File IDs from URLs
**Common patterns:**
```python
# From full URL
url = "https://docs.google.com/document/d/1rX7KHFnHyoAu3KrIvQgv0gJdTvMztWJT-Pkx5x954vc/edit"
file_id = url.split('/d/')[1].split('/')[0] # '1rX7KHFnHyoAu3KrIvQgv0gJdTvMztWJT-Pkx5x954vc'
# From sharing URL
url = "https://drive.google.com/file/d/1ABC123xyz/view"
file_id = url.split('/d/')[1].split('/')[0] # '1ABC123xyz'
```
## Performance Tips
1. Use helper script functions to minimize authentication overhead
2. Authenticate once and reuse the `drive` instance
3. Use specific search queries instead of listing all files
4. Batch operations when uploading/downloading multiple files
5. Cache file IDs for frequently accessed files

# PyDrive2 API Quick Reference
## Core Methods
### Create File Object
```python
# New file
file = drive.CreateFile({'title': 'filename.txt'})
# Existing file by ID
file = drive.CreateFile({'id': 'FILE_ID_HERE'})
# File in specific folder
file = drive.CreateFile({
'title': 'filename.txt',
'parents': [{'id': 'FOLDER_ID'}]
})
```
### Upload Operations
```python
# Upload from local file
file.SetContentFile('/path/to/local/file.txt')
file.Upload()
# Upload from string
file.SetContentString('Hello, World!')
file.Upload()
# Upload from string with markdown MIME type
file = drive.CreateFile({
'title': 'document.md',
'mimeType': 'text/markdown'
})
file.SetContentString('# My Document\n\nMarkdown content here')
file.Upload()
# Upload with metadata update
file['title'] = 'New Title'
file.Upload()
```
### Download Operations
```python
# Download to local file
file.GetContentFile('/path/to/download/location.txt')
# Get content as string
content = file.GetContentString()
# Get content as file object
file_obj = file.GetContentFile() # Returns file object
```
### Metadata Operations
```python
# Fetch metadata
file.FetchMetadata()
# Access metadata fields
title = file['title']
mime_type = file['mimeType']
file_size = file['fileSize']
created = file['createdDate']
modified = file['modifiedDate']
web_link = file['alternateLink']
# Update metadata
file['title'] = 'New Title'
file['description'] = 'Updated description'
file.Upload() # Save changes
```
### List/Search Operations
```python
# List all files
file_list = drive.ListFile().GetList()
# List with query
file_list = drive.ListFile({'q': "title contains 'report'"}).GetList()
# List with pagination
file_list = drive.ListFile({
'q': "trashed = false",
'maxResults': 10
}).GetList()
# Iterate through results
for file in file_list:
print(f"{file['title']} - {file['id']}")
```
### Delete Operations
```python
# Move to trash
file.Trash()
# Permanently delete
file.Delete()
# Restore from trash
file.UnTrash()
```
### Permission Operations
```python
# Get permissions
permissions = file.GetPermissions()
# Share with specific user
permission = file.InsertPermission({
'type': 'user',
'value': 'user@example.com',
'role': 'reader'
})
# Share with anyone (public)
permission = file.InsertPermission({
'type': 'anyone',
'role': 'reader'
})
# Remove permission
file.DeletePermission(permission_id)
```
## Metadata Fields Reference
### Common File Fields
```python
file['id'] # File ID
file['title'] # File name
file['mimeType'] # MIME type
file['description'] # Description
file['createdDate'] # Creation timestamp
file['modifiedDate'] # Last modified timestamp
file['fileSize'] # Size in bytes
file['parents'] # Parent folder IDs
file['owners'] # Owner information
file['alternateLink'] # Web view link
file['downloadUrl'] # Direct download URL
file['thumbnailLink'] # Thumbnail URL
file['shared'] # Shared status (boolean)
file['trashed'] # Trash status (boolean)
```
## Export Google Docs
```python
# Export Google Doc as PDF
file = drive.CreateFile({'id': 'DOC_ID'})
file.GetContentFile('output.pdf', mimetype='application/pdf')
# Export Google Sheet as Excel
file.GetContentFile('output.xlsx',
mimetype='application/vnd.openxmlformats-officedocument.spreadsheetml.sheet')
# Export Google Slides as PowerPoint
file.GetContentFile('output.pptx',
mimetype='application/vnd.openxmlformats-officedocument.presentationml.presentation')
```
## Folder Operations
```python
# Create folder
folder = drive.CreateFile({
'title': 'My Folder',
'mimeType': 'application/vnd.google-apps.folder'
})
folder.Upload()
# List files in folder
file_list = drive.ListFile({
'q': f"'{folder['id']}' in parents and trashed = false"
}).GetList()
# Upload file to folder
file = drive.CreateFile({
'title': 'file.txt',
'parents': [{'id': folder['id']}]
})
file.SetContentString('Content')
file.Upload()
```
## Error Handling
```python
from pydrive2.files import ApiRequestError
try:
file = drive.CreateFile({'id': 'FILE_ID'})
file.FetchMetadata()
except ApiRequestError as e:
if e.error['code'] == 404:
print("File not found")
else:
print(f"Error: {e}")
```
## Batch Operations
```python
# Upload multiple files
files_to_upload = [
('file1.txt', '/path/to/file1.txt'),
('file2.txt', '/path/to/file2.txt'),
]
for title, path in files_to_upload:
file = drive.CreateFile({'title': title})
file.SetContentFile(path)
file.Upload()
print(f"Uploaded {title}: {file['id']}")
```
## Advanced Features
### Resumable Upload (for large files)
```python
# PyDrive2 handles resumable uploads automatically
# Just use normal upload for large files
file = drive.CreateFile({'title': 'large_file.zip'})
file.SetContentFile('/path/to/large_file.zip')
file.Upload() # Automatically uses resumable upload
```
### File Revisions
```python
# List revisions
revisions = file.GetRevisions()
for rev in revisions:
print(f"Revision ID: {rev['id']}")
print(f"Modified: {rev['modifiedDate']}")
```
### Copy File
```python
# Copy file
original = drive.CreateFile({'id': 'ORIGINAL_FILE_ID'})
copied = original.Copy()
copied['title'] = 'Copy of ' + original['title']
copied.Upload()
```
## Performance Tips
1. **Fetch only needed fields**: Use `fields` parameter
2. **Batch operations**: Group multiple API calls when possible
3. **Cache metadata**: Store frequently accessed metadata locally
4. **Use file IDs**: Faster than searching by title

# Google Drive API Authentication Setup
## Quick Setup (Already Configured)
Authentication is already configured at:
- **Credentials**: `~/.gdrivelm/credentials.json`
- **Settings**: `~/.gdrivelm/settings.yaml`
- **Token**: `~/.gdrivelm/token.json` (auto-generated)
- **Virtual Env**: `~/Desktop/zPersonalProjects/gdrivelm/venv/` (update to your path)
## Authentication Code Pattern
```python
from pydrive2.auth import GoogleAuth
from pydrive2.drive import GoogleDrive
import os
def authenticate():
"""Authenticate with Google Drive API"""
settings_path = os.path.expanduser('~/.gdrivelm/settings.yaml')
token_path = os.path.expanduser('~/.gdrivelm/token.json')
gauth = GoogleAuth(settings_file=settings_path)
gauth.LoadCredentialsFile(token_path)
if gauth.credentials is None:
gauth.LocalWebserverAuth()
elif gauth.access_token_expired:
gauth.Refresh()
else:
gauth.Authorize()
gauth.SaveCredentialsFile(token_path)
return GoogleDrive(gauth)
```
## Settings Configuration
Located at `~/.gdrivelm/settings.yaml`:
```yaml
client_config_backend: file
client_config_file: /Users/wz/.gdrivelm/credentials.json
save_credentials: True
save_credentials_backend: file
save_credentials_file: /Users/wz/.gdrivelm/token.json
get_refresh_token: True
oauth_scope:
- https://www.googleapis.com/auth/drive
- https://www.googleapis.com/auth/drive.file
- https://www.googleapis.com/auth/drive.metadata.readonly
```
## OAuth Scopes
- `https://www.googleapis.com/auth/drive` - Full Drive access
- `https://www.googleapis.com/auth/drive.file` - Per-file access
- `https://www.googleapis.com/auth/drive.metadata.readonly` - Metadata reading
## First Run
On first use, the authentication will:
1. Open browser for OAuth consent
2. Save token to `~/.gdrivelm/token.json`
3. Auto-refresh on subsequent uses
## Python Environment
Always activate the virtual environment first:
```bash
cd ~/Desktop/zPersonalProjects/gdrivelm
source venv/bin/activate
```
## Installed Packages
- PyDrive2 v1.21.3
- google-api-python-client v2.187.0
- google-auth-oauthlib v1.2.3
- google-auth-httplib2 v0.2.1

# Google Drive Search Query Syntax
## Query Operators
| Query | Description |
|-------|-------------|
| `title contains 'text'` | Files with title containing text |
| `fullText contains 'text'` | Search file content |
| `mimeType = 'type'` | Files of specific MIME type |
| `'parent_id' in parents` | Files in specific folder |
| `'root' in parents` | Files in root directory |
| `trashed = false` | Not in trash |
| `trashed = true` | In trash |
| `'me' in owners` | Files you own |
| `starred = true` | Starred files |
| `modifiedDate > 'date'` | Modified after date |
| `modifiedDate < 'date'` | Modified before date |
| `createdDate > 'date'` | Created after date |
## Common MIME Types
| Type | MIME Type |
|------|-----------|
| PDF | `application/pdf` |
| Text | `text/plain` |
| Word | `application/vnd.openxmlformats-officedocument.wordprocessingml.document` |
| Excel | `application/vnd.openxmlformats-officedocument.spreadsheetml.sheet` |
| PowerPoint | `application/vnd.openxmlformats-officedocument.presentationml.presentation` |
| Google Doc | `application/vnd.google-apps.document` |
| Google Sheet | `application/vnd.google-apps.spreadsheet` |
| Google Slides | `application/vnd.google-apps.presentation` |
| Folder | `application/vnd.google-apps.folder` |
| Image | `image/jpeg`, `image/png`, `image/gif` |
## Search Examples
### Basic Searches
```python
# Files containing "report" in title
file_list = drive.ListFile({'q': "title contains 'report'"}).GetList()
# PDF files only
file_list = drive.ListFile({'q': "mimeType = 'application/pdf'"}).GetList()
# Files in root, not trashed
file_list = drive.ListFile({'q': "'root' in parents and trashed = false"}).GetList()
```
### Complex Queries
```python
# Multiple conditions with AND
query = (
"title contains 'invoice' and "
"mimeType = 'application/pdf' and "
"trashed = false"
)
file_list = drive.ListFile({'q': query}).GetList()
# Files you own
file_list = drive.ListFile({'q': "'me' in owners"}).GetList()
# Modified after specific date
file_list = drive.ListFile({'q': "modifiedDate > '2024-01-01'"}).GetList()
# Folders only
file_list = drive.ListFile({'q': "mimeType = 'application/vnd.google-apps.folder'"}).GetList()
# Starred PDFs
query = "starred = true and mimeType = 'application/pdf'"
file_list = drive.ListFile({'q': query}).GetList()
```
### Content Search
```python
# Search file content (not just title)
file_list = drive.ListFile({'q': "fullText contains 'keyword'"}).GetList()
```
## Date Format
Use ISO 8601 format: `YYYY-MM-DD` or `YYYY-MM-DDTHH:MM:SS`
Examples:
- `'2024-01-01'`
- `'2024-12-31T23:59:59'`
## Combining Conditions
Use `and` and `or` operators:
```python
# Either condition
query = "title contains 'report' or title contains 'summary'"
# Both conditions
query = "title contains 'report' and mimeType = 'application/pdf'"
# Complex combination
query = (
"(title contains 'invoice' or title contains 'receipt') and "
"mimeType = 'application/pdf' and "
"modifiedDate > '2024-01-01'"
)
```
## Special Characters
Escape single quotes in search terms:
```python
# Searching for "O'Brien"
query = "title contains 'O\\'Brien'"
```
## Performance Tips
1. **Be specific**: More specific queries return faster
2. **Limit fields**: Use `fields` parameter to request only needed data
3. **Use pagination**: For large result sets, use `pageToken`
4. **Avoid fullText searches**: They are slower than title searches
## Iterating Results
```python
# Process all results
file_list = drive.ListFile({'q': "title contains 'report'"}).GetList()
for file in file_list:
print(f"{file['title']} (ID: {file['id']})")
print(f" Modified: {file['modifiedDate']}")
print(f" Size: {file.get('fileSize', 'N/A')} bytes")
```

name: Making Files Clearer
description: Simplify and clarify files by removing redundancy, organizing content logically, and keeping only essential information. Use when asked to make something clearer, remove fluff, simplify, declutter, make more concise, or improve readability. Keywords - clarity, simplify, concise, declutter, remove redundancy, essential only, no fluff.

# Making Files Clearer
A systematic approach to transforming verbose, redundant, or disorganized files into clear, concise, essential-only content.
## Core Principles
### 1. Ruthless Elimination
- **Remove redundancy**: Delete duplicate information, repeated explanations, and overlapping content
- **Cut fluff**: Eliminate unnecessary adjectives, hedging language, and verbose phrasing
- **Strip decorative elements**: Remove ASCII art, excessive formatting, and visual noise unless they serve a functional purpose
### 2. Essential Information Only
- **Keep what matters**: Retain only information that directly serves the file's purpose
- **Question every line**: Ask "Does removing this change understanding?" If no, remove it
- **Preserve accuracy**: Never sacrifice correctness for brevity
### 3. Strategic Examples
- **Examples add clarity when**:
- Concept is abstract or counterintuitive
- Multiple valid interpretations exist
- Common mistakes need illustration
- **Examples are unnecessary when**:
- Concept is self-evident
- They merely repeat what's already clear
- They're "nice to have" but not essential
### 4. Logical Organization
- **Group related content**: Cluster similar topics together
- **Progressive structure**: Simple concepts before complex ones
- **Clear hierarchy**: Use headings to show relationships
- **Scannable format**: Readers should find information quickly
## Workflow
### Step 1: Create Backup
```bash
cp original.md original.md.backup
```
### Step 2: Analyze Current State
1. Read the entire file
2. Identify the file's core purpose
3. List essential information categories
4. Note redundant sections, fluff, and organizational issues
### Step 3: Create Clarity Plan
Before editing, outline:
- What to keep (essential information)
- What to remove (redundancy, fluff)
- How to reorganize (new structure)
- Where examples add value
### Step 4: Execute Transformation
Apply changes systematically:
1. **Remove**: Delete redundant and unnecessary content
2. **Reorganize**: Restructure for logical flow
3. **Clarify**: Rewrite unclear sections concisely
4. **Validate**: Ensure no essential information lost
### Step 5: Present Changes for Review
Show the user:
- Summary of what changed
- Before/after comparison
- Ask for confirmation
### Step 6: Finalize
After user confirms:
```bash
rm original.md.backup
```
If user rejects changes:
```bash
mv original.md.backup original.md
```
## Common Clarity Anti-Patterns
### Redundancy
❌ **Bad**: Explaining the same concept multiple times in different words
✅ **Good**: One clear explanation, possibly with a targeted example
### Unnecessary Examples
❌ **Bad**: "For instance, if you have a variable `x = 5`, that's an example of setting a variable"
✅ **Good**: "Variables store values: `x = 5`"
### Verbose Phrasing
❌ **Bad**: "It is important to note that you should always make sure to..."
✅ **Good**: "Always..."
### Over-Documentation
❌ **Bad**: Documenting every obvious step
✅ **Good**: Documenting non-obvious behavior and gotchas
### Poor Organization
❌ **Bad**: Random topic ordering, nested sections with unclear purpose
✅ **Good**: Logical grouping, clear hierarchy, scannable headings
## Output Format
When making a file clearer:
1. **Show before/after comparison** (if file is small enough):
```
Original: 250 lines, 15 sections, 30% redundancy
Revised: 120 lines, 8 sections, focused content
```
2. **Summarize changes**:
- What was removed and why
- How content was reorganized
- Where examples were added/removed
3. **Present the clarified content**: Use Edit tool to update the file
4. **Validate**: Confirm all essential information preserved
## Edge Cases
- **Technical documentation**: Preserve all technical accuracy; brevity should never compromise correctness
- **Legal/compliance files**: Consult before removing anything that might be required
- **Tutorials**: Examples are often essential; keep those that teach, remove those that just show off
- **Configuration files**: Comments may seem verbose but often prevent errors; keep contextual comments
## Success Criteria
A file is clearer when:
- A first-time reader understands it faster
- Information is findable without scrolling/searching extensively
- No questions arise from ambiguity or missing context
- The file can be maintained more easily
- Essential information density is maximized

## About Skills
Skills are modular, self-contained packages that extend Claude's capabilities by providing
specialized knowledge, workflows, and tools. Think of them as "onboarding guides" for specific
domains or tasks—they transform Claude from a general-purpose agent into a specialized agent
equipped with procedural knowledge that no model can fully possess.
### What Skills Provide
1. Specialized workflows - Multi-step procedures for specific domains
2. Tool integrations - Instructions for working with specific file formats or APIs
3. Domain expertise - Company-specific knowledge, schemas, business logic
4. Bundled resources - Scripts, references, and assets for complex and repetitive tasks
### Anatomy of a Skill
Every skill consists of a required SKILL.md file and optional bundled resources:
```
skill-name/
├── SKILL.md (required)
│ ├── YAML frontmatter metadata (required)
│ │ ├── name: (required)
│ │ └── description: (required)
│ └── Markdown instructions (required)
└── Bundled Resources (optional)
├── scripts/ - Executable code (Python/Bash/etc.)
├── references/ - Documentation intended to be loaded into context as needed
└── assets/ - Files used in output (templates, icons, fonts, etc.)
```
#### SKILL.md (required)
**Metadata Quality:** The `name` and `description` in YAML frontmatter determine when Claude will use the skill. Be specific about what the skill does and when to use it. Use the third-person (e.g. "This skill should be used when..." instead of "Use this skill when...").
**Critical Format Rule:** Do NOT include overview sections or "When to Use This Skill" sections in the SKILL.md body. This information belongs ONLY in the YAML frontmatter description. The body should contain ONLY procedural instructions on how to use the skill.
**Incorrect format:**
```markdown
---
name: example
description: Brief description
---
# Example Skill Title
Overview paragraph explaining what the skill does.
## When to Use This Skill
- Use case 1
- Use case 2
## How to Use
Instructions here...
```
**Correct format:**
```markdown
---
name: example
description: Detailed description including what the skill does, when to use it (use case 1, use case 2, etc.), and what it provides. Use when working with X, Y, and Z operations.
---
## How to Use
Instructions here (no overview, no "when to use" section)...
```
#### Bundled Resources (optional)
##### Scripts (`scripts/`)
Executable code (Python/Bash/etc.) for tasks that require deterministic reliability or are repeatedly rewritten.
- **When to include**: When the same code is being rewritten repeatedly or deterministic reliability is needed
- **Example**: `scripts/rotate_pdf.py` for PDF rotation tasks
- **Benefits**: Token efficient, deterministic, may be executed without loading into context
- **Note**: Scripts may still need to be read by Claude for patching or environment-specific adjustments
##### References (`references/`)
Documentation and reference material intended to be loaded as needed into context to inform Claude's process and thinking.
- **When to include**: For documentation that Claude should reference while working
- **Examples**: `references/finance.md` for financial schemas, `references/mnda.md` for company NDA template, `references/policies.md` for company policies, `references/api_docs.md` for API specifications
- **Use cases**: Database schemas, API documentation, domain knowledge, company policies, detailed workflow guides
- **Benefits**: Keeps SKILL.md lean, loaded only when Claude determines it's needed
- **Best practice**: If files are large (>10k words), include grep search patterns in SKILL.md
- **Avoid duplication**: Information should live in either SKILL.md or references files, not both. Prefer references files for detailed information unless it's truly core to the skill—this keeps SKILL.md lean while making information discoverable without hogging the context window. Keep only essential procedural instructions and workflow guidance in SKILL.md; move detailed reference material, schemas, and examples to references files.
##### Assets (`assets/`)
Files not intended to be loaded into context, but rather used within the output Claude produces.
- **When to include**: When the skill needs files that will be used in the final output
- **Examples**: `assets/logo.png` for brand assets, `assets/slides.pptx` for PowerPoint templates, `assets/frontend-template/` for HTML/React boilerplate, `assets/font.ttf` for typography
- **Use cases**: Templates, images, icons, boilerplate code, fonts, sample documents that get copied or modified
- **Benefits**: Separates output resources from documentation, enables Claude to use files without loading them into context
### Progressive Disclosure Design Principle
Skills use a three-level loading system to manage context efficiently:
1. **Metadata (name + description)** - Always in context (~100 words)
2. **SKILL.md body** - When skill triggers (<5k words)
3. **Bundled resources** - As needed by Claude (Unlimited*)
*Unlimited because scripts can be executed without reading into context window.
## Skill Creation Process
To create a skill, follow the "Skill Creation Process" in order, skipping steps only if there is a clear reason why they are not applicable.
### Step 1: Understanding the Skill with Concrete Examples
Skip this step only when the skill's usage patterns are already clearly understood. It remains valuable even when working with an existing skill.
To create an effective skill, clearly understand concrete examples of how the skill will be used. This understanding can come from either direct user examples or generated examples that are validated with user feedback.
For example, when building an image-editor skill, relevant questions include:
- "What functionality should the image-editor skill support? Editing, rotating, anything else?"
- "Can you give some examples of how this skill would be used?"
- "I can imagine users asking for things like 'Remove the red-eye from this image' or 'Rotate this image'. Are there other ways you imagine this skill being used?"
- "What would a user say that should trigger this skill?"
To avoid overwhelming users, avoid asking too many questions in a single message. Start with the most important questions and follow up as needed for better effectiveness.
Conclude this step when there is a clear sense of the functionality the skill should support.
### Step 2: Planning the Reusable Skill Contents
To turn concrete examples into an effective skill, analyze each example by:
1. Considering how to execute on the example from scratch
2. Identifying what scripts, references, and assets would be helpful when executing these workflows repeatedly
Example: When building a `pdf-editor` skill to handle queries like "Help me rotate this PDF," the analysis shows:
1. Rotating a PDF requires re-writing the same code each time
2. A `scripts/rotate_pdf.py` script would be helpful to store in the skill
Example: When designing a `frontend-webapp-builder` skill for queries like "Build me a todo app" or "Build me a dashboard to track my steps," the analysis shows:
1. Writing a frontend webapp requires the same boilerplate HTML/React each time
2. An `assets/hello-world/` template containing the boilerplate HTML/React project files would be helpful to store in the skill
Example: When building a `big-query` skill to handle queries like "How many users have logged in today?" the analysis shows:
1. Querying BigQuery requires re-discovering the table schemas and relationships each time
2. A `references/schema.md` file documenting the table schemas would be helpful to store in the skill
To establish the skill's contents, analyze each concrete example to create a list of the reusable resources to include: scripts, references, and assets.
### Step 3: Initializing the Skill
At this point, it is time to actually create the skill.
Skip this step only if the skill being developed already exists, and iteration or packaging is needed. In this case, continue to the next step.
**For Warren's system**, create the skill directory manually in the default location:
```bash
# Create skill directory in Warren's plugin
mkdir -p ~/.claude/plugins/marketplaces/warren-claude-code-plugin-marketplace/claude-context-orchestrator/skills/my-skill
# Create subdirectories as needed
mkdir -p ~/.claude/plugins/marketplaces/warren-claude-code-plugin-marketplace/claude-context-orchestrator/skills/my-skill/scripts
mkdir -p ~/.claude/plugins/marketplaces/warren-claude-code-plugin-marketplace/claude-context-orchestrator/skills/my-skill/references
mkdir -p ~/.claude/plugins/marketplaces/warren-claude-code-plugin-marketplace/claude-context-orchestrator/skills/my-skill/assets
```
**If using Anthropic's init_skill.py script** (for other systems):
```bash
scripts/init_skill.py <skill-name> --path <output-directory>
```
The script creates a template with proper frontmatter and example directories.
After initialization, customize or remove the generated SKILL.md and example files as needed.
### Step 4: Edit the Skill
When editing the (newly-generated or existing) skill, remember that the skill is being created for another instance of Claude to use. Focus on including information that would be beneficial and non-obvious to Claude. Consider what procedural knowledge, domain-specific details, or reusable assets would help another Claude instance execute these tasks more effectively.
#### Start with Reusable Skill Contents
To begin implementation, start with the reusable resources identified above: `scripts/`, `references/`, and `assets/` files. Note that this step may require user input. For example, when implementing a `brand-guidelines` skill, the user may need to provide brand assets or templates to store in `assets/`, or documentation to store in `references/`.
Also, delete any example files and directories not needed for the skill. The initialization script creates example files in `scripts/`, `references/`, and `assets/` to demonstrate structure, but most skills won't need all of them.
#### Update SKILL.md
**Writing Style:** Write the entire skill using **imperative/infinitive form** (verb-first instructions), not second person. Use objective, instructional language (e.g., "To accomplish X, do Y" rather than "You should do X" or "If you need to do X"). This maintains consistency and clarity for AI consumption.
**Content Organization:**
1. **YAML Frontmatter (required):**
- `name`: Skill identifier
- `description`: Comprehensive description that includes:
- What the skill does
- When to use it (all use cases)
- What it provides (features, capabilities)
- Any pre-configured elements
2. **Markdown Body (required):**
- **Start directly with procedural sections** (e.g., "## Environment Setup", "## Helper Script Usage")
- **Do NOT include:**
- Title headers repeating the skill name
- Overview/introduction paragraphs
- "When to Use This Skill" sections
- "What This Skill Provides" sections
- **DO include:**
- Setup instructions
- Usage examples
- Common operations
- Workflow guidelines
- References to bundled resources
**Example structure:**
```markdown
---
name: my-skill
description: [Complete description with all use cases and features]
---
## Environment Setup
[Setup instructions]
## Using the Helper Script
[How to use scripts/]
## Common Operations
[Examples and patterns]
```
All reusable skill contents (scripts, references, assets) should be referenced in the body so Claude knows how to use them.
### Step 5: Packaging a Skill
Once the skill is ready, it should be packaged into a distributable zip file that gets shared with the user. The packaging process automatically validates the skill first to ensure it meets all requirements:
```bash
scripts/package_skill.py <path/to/skill-folder>
```
Optional output directory specification:
```bash
scripts/package_skill.py <path/to/skill-folder> ./dist
```
The packaging script will:
1. **Validate** the skill automatically, checking:
- YAML frontmatter format and required fields
- Skill naming conventions and directory structure
- Description completeness and quality
- File organization and resource references
2. **Package** the skill if validation passes, creating a zip file named after the skill (e.g., `my-skill.zip`) that includes all files and maintains the proper directory structure for distribution.
If validation fails, the script will report the errors and exit without creating a package. Fix any validation errors and run the packaging command again.
**Note:** For Warren's system, skills are typically not packaged as zip files but remain in place within the plugin directory structure.
### Step 6: Iterate
After testing the skill, users may request improvements. Often this happens right after using the skill, with fresh context of how the skill performed.
**Iteration workflow:**
1. Use the skill on real tasks
2. Notice struggles or inefficiencies
3. Identify how SKILL.md or bundled resources should be updated
4. Implement changes and test again
---
## Snippet Integration (Warren's System)
Skills in Warren's system can be enhanced with **snippet integration** for instant keyword activation. This allows skills to be triggered by specific keywords in user prompts, providing explicit control over when a skill loads.
### When to Add Snippet Integration
Add snippet integration when:
- Skill needs instant activation by specific keyword (e.g., "USE SKILL_NAME")
- Skill is used frequently in specific contexts
- Want to bypass automatic skill discovery and ensure deterministic loading
### How to Add Snippet Integration
1. **Read the managing-snippets skill** for detailed instructions on snippet management
2. **Add entry to config.local.json** at:
```
~/.claude/plugins/marketplaces/warren-claude-code-plugin-marketplace/claude-context-orchestrator/config.local.json
```
3. **Example snippet pattern:**
```json
{
"hooks": {
"user-prompt-submit": {
"enabled": true,
"order": 0,
"patterns": [
{
"regex": "\\bUSE MY-SKILL\\b",
"command": "~/.claude/plugins/marketplaces/warren-claude-code-plugin-marketplace/claude-context-orchestrator/scripts/read-skill.sh 'my-skill'"
}
]
}
}
}
```
4. **Test the snippet:**
- Type "USE MY-SKILL" in a prompt
- Verify the skill content loads
5. **Restart Claude Code** to activate the snippet
### Snippet vs. Automatic Discovery
**Automatic Discovery:**
- Claude decides when to load skill based on description
- More flexible, adapts to varied user phrasings
- Relies on good description metadata
**Snippet Activation:**
- User explicitly triggers skill with keyword
- Deterministic loading every time
- Useful for workflows where skill should always be active
**Recommendation:** Use both approaches together. Let automatic discovery handle most cases, and provide snippet keywords for power users who want explicit control.

# Creating Skills
Step-by-step guidance for creating new Agent Skills in Claude Code.
## Quick Start
### 1. Choose Skill Location
**Personal Skills** (`~/.claude/skills/`):
- Individual workflows
- Experimental skills
- Personal productivity tools
**Project Skills** (`.claude/skills/`):
- Team workflows
- Project-specific expertise
- Shared utilities (commit to git)
**Plugin Skills** (plugin's `skills/` directory):
- Distributable skills
- Part of a plugin package
- Automatically available when plugin installed
### 2. Create Skill Directory
```bash
# Personal
mkdir -p ~/.claude/skills/my-skill-name
# Project
mkdir -p .claude/skills/my-skill-name
# Plugin
mkdir -p path/to/plugin/skills/my-skill-name
```
### 3. Create SKILL.md
Minimum required structure:
```yaml
---
name: Your Skill Name
description: What it does and when to use it (include trigger terms)
---
# Your Skill Name
## Instructions
Provide clear, step-by-step guidance.
## Examples
Show concrete examples of using this skill.
```
## Writing Effective Descriptions
The `description` field is critical for skill discovery.
### Requirements
- **Write in third person** (goes into system prompt)
- **Include WHAT the skill does**
- **Include WHEN to use it**
- **Add specific trigger terms** users would mention
- **Maximum 1024 characters**
### Good Examples
**PDF Processing**:
```yaml
description: Extract text and tables from PDF files, fill forms, merge documents. Use when working with PDF files or when the user mentions PDFs, forms, or document extraction.
```
**Excel Analysis**:
```yaml
description: Analyze Excel spreadsheets, create pivot tables, generate charts. Use when analyzing Excel files, spreadsheets, tabular data, or .xlsx files.
```
**Git Commit Helper**:
```yaml
description: Generate descriptive commit messages by analyzing git diffs. Use when the user asks for help writing commit messages or reviewing staged changes.
```
### Bad Examples
```yaml
description: Helps with documents # Too vague
description: Processes data # Not specific enough
description: Does stuff with files # No trigger terms
```
## Skill Structure Guidelines
### Keep Skills Focused
One skill = one capability
**Good** (focused):
- "PDF form filling"
- "Excel data analysis"
- "Git commit messages"
**Too broad** (split into multiple skills):
- "Document processing"
- "Data tools"
- "File operations"
### Use Progressive Disclosure
Keep SKILL.md under 500 lines. Split content into separate files.
**Pattern**:
```
my-skill/
├── SKILL.md # Main instructions (< 500 lines)
├── reference.md # Detailed API docs
├── examples.md # Usage examples
└── scripts/
└── helper.py # Utility scripts
```
**In SKILL.md**:
```markdown
# My Skill
## Quick Start
[Brief overview and common usage]
## Advanced Features
For complete API documentation, see [reference.md](reference.md).
For usage patterns, see [examples.md](examples.md).
```
Claude loads additional files only when needed.
### Avoid Deeply Nested References
**Keep references one level deep from SKILL.md**.
**Bad** (too deep):
```markdown
# SKILL.md
See [advanced.md](advanced.md)...
# advanced.md
See [details.md](details.md)...
# details.md
Here's the actual information...
```
**Good** (one level):
```markdown
# SKILL.md
**Basic usage**: [instructions in SKILL.md]
**Advanced features**: See [advanced.md](advanced.md)
**API reference**: See [reference.md](reference.md)
**Examples**: See [examples.md](examples.md)
```
### Structure Longer Reference Files
For reference files >100 lines, include a table of contents:
```markdown
# API Reference
## Contents
- Authentication and setup
- Core methods (create, read, update, delete)
- Advanced features (batch operations, webhooks)
- Error handling patterns
- Code examples
## Authentication and Setup
...
## Core Methods
...
```
## Content Guidelines
### Be Concise
**Challenge each piece of information**:
- Does Claude really need this explanation?
- Can I assume Claude knows this?
- Does this justify its token cost?
**Good** (concise):
````markdown
## Extract PDF Text
Use pdfplumber:
```python
import pdfplumber
with pdfplumber.open("file.pdf") as pdf:
text = pdf.pages[0].extract_text()
```
````
**Bad** (too verbose):
```markdown
## Extract PDF Text
PDF (Portable Document Format) files are a common file format that contains
text, images, and other content. To extract text from a PDF, you'll need to
use a library. There are many libraries available for PDF processing, but we
recommend pdfplumber because it's easy to use and handles most cases well.
First, you'll need to install it using pip. Then you can use the code below...
```
### Use Consistent Terminology
Choose one term and use it throughout:
**Good**:
- Always "API endpoint"
- Always "field"
- Always "extract"
**Bad**:
- Mix "API endpoint", "URL", "API route", "path"
- Mix "field", "box", "element", "control"
### Avoid Time-Sensitive Information
**Bad**:
```markdown
If you're doing this before August 2025, use the old API.
```
**Good**:
```markdown
## Current Method
Use the v2 API: `api.example.com/v2/messages`
## Old Patterns
<details>
<summary>Legacy v1 API (deprecated 2025-08)</summary>
The v1 API used: `api.example.com/v1/messages`
This endpoint is no longer supported.
</details>
```
## Tool Restrictions (Optional)
Use `allowed-tools` to limit which tools Claude can use when the skill is active:
```yaml
---
name: Safe File Reader
description: Read files without making changes. Use when you need read-only file access.
allowed-tools: Read, Grep, Glob
---
# Safe File Reader
This skill provides read-only file access.
## Instructions
1. Use Read to view file contents
2. Use Grep to search within files
3. Use Glob to find files by pattern
```
When this skill is active, Claude can only use the specified tools without asking permission.
**Use cases**:
- Read-only skills that shouldn't modify files
- Limited scope skills (e.g., only data analysis, no file writing)
- Security-sensitive workflows
## Testing Your Skill
### 1. Test by Asking Relevant Questions
Ask questions that match your description:
**Example**: If your description mentions "PDF files":
```
Can you help me extract text from this PDF?
```
Claude should autonomously use your skill.
### 2. Check Skill Discovery
**List all skills**:
Ask Claude: "What skills are available?"
**Verify file structure**:
```bash
# Personal
ls ~/.claude/skills/my-skill/SKILL.md
# Project
ls .claude/skills/my-skill/SKILL.md
```
### 3. Debug Common Issues
**Skill doesn't activate**:
- Make description more specific
- Include trigger terms users would mention
- Add "when to use" guidance
**YAML syntax errors**:
```bash
cat SKILL.md | head -n 10
```
Ensure:
- Opening `---` on line 1
- Closing `---` before markdown
- Valid YAML (no tabs, correct indentation)
**Wrong location**:
Check skill is in correct directory with SKILL.md file.
## Complete Examples
### Simple Skill (Single File)
```
commit-helper/
└── SKILL.md
```
**SKILL.md**:
```yaml
---
name: Generating Commit Messages
description: Generates clear commit messages from git diffs. Use when writing commit messages or reviewing staged changes.
---
# Generating Commit Messages
## Instructions
1. Run `git diff --staged` to see changes
2. Suggest a commit message with:
- Summary under 50 characters
- Detailed description
- Affected components
## Best Practices
- Use present tense
- Explain what and why, not how
```
### Multi-File Skill
```
pdf-processing/
├── SKILL.md
├── FORMS.md
├── REFERENCE.md
└── scripts/
├── fill_form.py
└── validate.py
```
**SKILL.md**:
````yaml
---
name: PDF Processing
description: Extract text, fill forms, merge PDFs. Use when working with PDF files, forms, or document extraction. Requires pypdf and pdfplumber packages.
---
# PDF Processing
## Quick Start
Extract text:
```python
import pdfplumber
with pdfplumber.open("doc.pdf") as pdf:
text = pdf.pages[0].extract_text()
```
For form filling, see [FORMS.md](FORMS.md).
For detailed API reference, see [REFERENCE.md](REFERENCE.md).
## Requirements
Install packages:
```bash
pip install pypdf pdfplumber
```
````
## Best Practices Summary
✅ **Do**:
- Write descriptions in third person
- Include trigger terms in description
- Keep SKILL.md under 500 lines
- Use progressive disclosure for large content
- Be concise - assume Claude is smart
- Use consistent terminology
- Test with relevant questions
- Keep skills focused (one capability per skill)
❌ **Don't**:
- Write vague descriptions
- Include time-sensitive information
- Nest references more than one level deep
- Over-explain things Claude already knows
- Create overly broad skills
- Use inconsistent terminology

# Deleting Skills
Guidance for safely removing Agent Skills from Claude Code.
## Quick Deletion Process
### 1. Locate the Skill
```bash
# Personal skills
ls ~/.claude/skills/
# Project skills
ls .claude/skills/
# Find specific skill
find ~/.claude/skills -name "SKILL.md" -path "*/my-skill/*"
```
### 2. Create Backup (Recommended)
Before deleting, create a backup:
```bash
# Backup entire skill directory
cp -r ~/.claude/skills/my-skill ~/.claude/skills/my-skill.backup
# Or backup to a dedicated location
cp -r ~/.claude/skills/my-skill ~/skill-backups/my-skill-$(date +%Y%m%d)
```
### 3. Delete the Skill
```bash
# Personal skill
rm -rf ~/.claude/skills/my-skill
# Project skill
rm -rf .claude/skills/my-skill
```
### 4. Verify Removal
Restart Claude Code and verify the skill is no longer available:
Ask Claude: "What skills are available?"
## Deletion Scenarios
### Delete Personal Skill
```bash
# Check it exists
ls ~/.claude/skills/my-skill/SKILL.md
# Backup
cp -r ~/.claude/skills/my-skill ~/.claude/skills/my-skill.backup
# Delete
rm -rf ~/.claude/skills/my-skill
# Verify
ls ~/.claude/skills/
```
No restart needed for personal skills if Claude Code wasn't using them.
### Delete Project Skill
For skills in `.claude/skills/` that are committed to git:
```bash
# Backup first
cp -r .claude/skills/my-skill ~/skill-backups/my-skill-backup
# Remove from git
git rm -rf .claude/skills/my-skill
# Commit
git commit -m "Remove my-skill: no longer needed"
# Push
git push
```
**Important**: Notify team members so they can pull the changes and restart Claude Code.
### Delete Plugin Skill
Plugin skills are managed by the plugin system. To remove:
**Option 1: Disable the plugin**
```
/plugin disable plugin-name@marketplace-name
```
**Option 2: Uninstall the plugin**
```
/plugin uninstall plugin-name@marketplace-name
```
You cannot delete individual skills from plugins. To modify plugin skills, fork the plugin or contact the plugin author.
## Bulk Deletion
### Delete Multiple Personal Skills
```bash
# List all personal skills
ls ~/.claude/skills/
# Backup all before deletion
cp -r ~/.claude/skills ~/skill-backups/all-skills-$(date +%Y%m%d)
# Delete specific skills
rm -rf ~/.claude/skills/skill1
rm -rf ~/.claude/skills/skill2
rm -rf ~/.claude/skills/skill3
```
### Delete All Unused Skills
```bash
# Backup first
cp -r ~/.claude/skills ~/skill-backups/all-skills-$(date +%Y%m%d)
# Review each skill before deleting
for skill in ~/.claude/skills/*; do
echo "Skill: $(basename $skill)"
echo "Description:"
head -n 10 "$skill/SKILL.md"
read -p "Delete this skill? (y/n) " -n 1 -r
echo
if [[ $REPLY =~ ^[Yy]$ ]]; then
rm -rf "$skill"
echo "Deleted: $(basename $skill)"
fi
done
```
## Backup Strategies
### Before Major Cleanup
Create a timestamped backup of all skills:
```bash
# Backup all personal skills
tar -czf ~/skill-backups/personal-skills-$(date +%Y%m%d-%H%M%S).tar.gz \
-C ~ .claude/skills
# Backup all project skills (from project root)
tar -czf ~/skill-backups/project-skills-$(date +%Y%m%d-%H%M%S).tar.gz \
.claude/skills
```
### Restore from Backup
```bash
# Restore all personal skills
tar -xzf ~/skill-backups/personal-skills-20251016-143022.tar.gz \
-C ~
# Restore specific skill
cp -r ~/skill-backups/my-skill-20251016 ~/.claude/skills/my-skill
```
## Version Control Best Practices
### For Project Skills
When deleting project skills from git repositories:
```bash
# Create feature branch
git checkout -b remove-unused-skills
# Remove skill
git rm -rf .claude/skills/old-skill
# Commit with explanation
git commit -m "Remove old-skill: replaced by new-skill
The old-skill has been superseded by new-skill which provides
better performance and additional features.
Team members should:
1. Pull this change
2. Restart Claude Code
3. The skill will no longer be available"
# Push and create PR
git push origin remove-unused-skills
```
### Document Removal
Update project documentation:
```markdown
# Changelog
## 2025-10-16
### Removed
- **old-skill**: Replaced by new-skill. See migration guide below.
### Migration Guide
If you were using old-skill:
1. Update your workflows to use new-skill instead
2. Key differences: [list changes]
3. See examples: [link to new-skill examples]
```
## Common Deletion Scenarios
### Skill No Longer Needed
```bash
# Simple removal
rm -rf ~/.claude/skills/deprecated-skill
```
### Skill Replaced by Better Version
```bash
# Backup old version (might need reference)
cp -r ~/.claude/skills/old-skill ~/skill-backups/old-skill-reference
# Delete old version
rm -rf ~/.claude/skills/old-skill
# The new version is already in place
ls ~/.claude/skills/new-skill
```
### Skill Conflicts with Another
If two skills activate on similar triggers:
```bash
# Review both skills
cat ~/.claude/skills/skill-a/SKILL.md | head -n 10
cat ~/.claude/skills/skill-b/SKILL.md | head -n 10
# Decide which to keep (usually the more specific one)
# Delete the less useful one
rm -rf ~/.claude/skills/skill-b
```
### Experimental Skill Didn't Work Out
```bash
# No backup needed for failed experiments
rm -rf ~/.claude/skills/experiment-skill
```
## Safety Checks
### Before Deleting, Ask:
1. **Is this skill used by others?**
- For project skills, check with team
- For personal skills, just you
2. **Is there a migration path?**
- If replacing, document new approach
- If removing, explain alternatives
3. **Have I backed it up?**
- Can I restore if needed?
- Do I have the content archived?
4. **Will this break workflows?**
- Check dependencies
- Update documentation
- Notify affected users
### Validation Checklist
Before deleting a project skill:
- [ ] Created backup
- [ ] Checked for dependents (other skills referencing this one)
- [ ] Notified team members
- [ ] Updated documentation
- [ ] Committed to version control with clear message
- [ ] Verified skill is not critical to current workflows
## Troubleshooting
### Skill Still Appears After Deletion
**Problem**: Deleted skill still shows up in available skills
**Solution**: Restart Claude Code to refresh skill registry
### Cannot Delete (Permission Denied)
```bash
# Check permissions
ls -la ~/.claude/skills/my-skill/
# Fix permissions if needed
chmod -R u+w ~/.claude/skills/my-skill/
# Then delete
rm -rf ~/.claude/skills/my-skill
```
### Accidentally Deleted Important Skill
**If you have a backup**:
```bash
# Restore from backup
cp -r ~/skill-backups/my-skill ~/.claude/skills/my-skill
# Restart Claude Code
```
**If no backup**:
- Check git history (for project skills)
- Check Time Machine or system backups
- Recreate from memory or documentation
### Team Member Still Has Deleted Skill
**For project skills**:
```bash
# Team member should pull latest changes
git pull
# Remove any local-only changes
rm -rf .claude/skills/deleted-skill
# Restart Claude Code
```
## Post-Deletion Cleanup
### Verify Skill List
After deletion, verify skills are as expected:
Ask Claude: "What skills are available?"
Or check filesystem:
```bash
# Personal skills
ls ~/.claude/skills/
# Project skills
ls .claude/skills/
```
### Update Documentation
If maintaining skill documentation:
```markdown
# Available Skills
## Active Skills
- skill-a: Description
- skill-b: Description
## Deprecated Skills
- ~~old-skill~~: Removed 2025-10-16, replaced by new-skill
```
### Clean Up References
Check for references to deleted skills in:
- Documentation files
- README files
- Other skills that might reference it
- Workflow documentation
```bash
# Find references
grep -r "old-skill" .claude/
grep -r "old-skill" docs/
```

# Reading Skills
Guidance for listing, viewing, and inspecting Agent Skills in Claude Code.
## Quick Reference
### List All Available Skills
Ask Claude:
```
What skills are available?
```
or
```
List all available skills
```
Claude will show all skills from:
- Personal skills (`~/.claude/skills/`)
- Project skills (`.claude/skills/`)
- Plugin skills (from installed plugins)
### View Specific Skill
```bash
# Personal skill
cat ~/.claude/skills/my-skill/SKILL.md
# Project skill
cat .claude/skills/my-skill/SKILL.md
# Open in editor
code ~/.claude/skills/my-skill/SKILL.md
```
## Filesystem Commands
### List Personal Skills
```bash
# List all personal skills
ls ~/.claude/skills/
# List with details
ls -la ~/.claude/skills/
# Show skill names only
ls -1 ~/.claude/skills/
```
### List Project Skills
```bash
# From project root
ls .claude/skills/
# Find all project skills recursively
find . -path "*/.claude/skills/*/SKILL.md"
```
### View Skill Metadata
Extract name and description from YAML frontmatter:
```bash
# View frontmatter
head -n 10 ~/.claude/skills/my-skill/SKILL.md
# Extract just description
grep "description:" ~/.claude/skills/my-skill/SKILL.md
```
### Check Skill Structure
```bash
# List all files in skill directory
ls -la ~/.claude/skills/my-skill/
# Show directory tree
tree ~/.claude/skills/my-skill/
# Or without tree command
find ~/.claude/skills/my-skill/ -type f
```
## Inspection Patterns
### View Complete Skill Content
```bash
# View entire SKILL.md
cat ~/.claude/skills/my-skill/SKILL.md
# View with pagination
less ~/.claude/skills/my-skill/SKILL.md
# View with line numbers
cat -n ~/.claude/skills/my-skill/SKILL.md
```
### View Skill Supporting Files
```bash
# List all markdown files
ls ~/.claude/skills/my-skill/*.md
# View reference file
cat ~/.claude/skills/my-skill/reference.md
# View examples
cat ~/.claude/skills/my-skill/examples.md
```
### Search Within Skills
```bash
# Search for keyword in specific skill
grep -r "PDF" ~/.claude/skills/pdf-processing/
# Search across all personal skills
grep -r "authentication" ~/.claude/skills/
# Case-insensitive search
grep -ri "docker" ~/.claude/skills/
```
### Check Skill Size
```bash
# Size of SKILL.md
wc -l ~/.claude/skills/my-skill/SKILL.md
# Total size of skill directory
du -sh ~/.claude/skills/my-skill/
# Detailed size breakdown
du -h ~/.claude/skills/my-skill/*
```
## Finding Skills
### By Name Pattern
```bash
# Find skills with "pdf" in name
ls ~/.claude/skills/ | grep -i pdf
# Find all skills with "processing" in name
find ~/.claude/skills/ -type d -name "*processing*"
```
### By Description Content
```bash
# Find skills mentioning "Excel"
grep -l "Excel" ~/.claude/skills/*/SKILL.md
# Find skills with "API" in description
grep "description:.*API" ~/.claude/skills/*/SKILL.md
```
### By Trigger Terms
```bash
# Find which skill handles "docker"
for skill in ~/.claude/skills/*/SKILL.md; do
if grep -qi "docker" "$skill"; then
echo "Found in: $(dirname $skill)"
grep "description:" "$skill"
fi
done
```
## Understanding Skill Structure
### Check if Skill Has allowed-tools
```bash
# Check frontmatter for allowed-tools
head -n 15 ~/.claude/skills/my-skill/SKILL.md | grep "allowed-tools"
```
If present, the skill restricts which tools Claude can use.
### Identify Progressive Disclosure
```bash
# Check if skill references other files
grep -E "\[.*\]\(.*\.md\)" ~/.claude/skills/my-skill/SKILL.md
# List referenced files
ls ~/.claude/skills/my-skill/*.md
```
Skills with multiple .md files use progressive disclosure.
### Check for Scripts
```bash
# Check if skill has scripts
ls ~/.claude/skills/my-skill/scripts/
# Check for templates
ls ~/.claude/skills/my-skill/templates/
```
## Comparing Skills
### Compare Two Skill Descriptions
```bash
# View both descriptions
echo "=== Skill A ==="
head -n 10 ~/.claude/skills/skill-a/SKILL.md
echo "=== Skill B ==="
head -n 10 ~/.claude/skills/skill-b/SKILL.md
```
### Find Overlapping Skills
```bash
# Check if two skills have similar descriptions
skill_a_desc=$(grep "description:" ~/.claude/skills/skill-a/SKILL.md)
skill_b_desc=$(grep "description:" ~/.claude/skills/skill-b/SKILL.md)
echo "Skill A: $skill_a_desc"
echo "Skill B: $skill_b_desc"
```
If descriptions overlap significantly, consider consolidating.
### Diff Two Skills
```bash
# Compare skill structures
diff ~/.claude/skills/skill-a/SKILL.md ~/.claude/skills/skill-b/SKILL.md
# Or use a better diff tool
code --diff ~/.claude/skills/skill-a/SKILL.md ~/.claude/skills/skill-b/SKILL.md
```
## Validation Checks
### Verify YAML Frontmatter
```bash
# Check frontmatter syntax
head -n 15 ~/.claude/skills/my-skill/SKILL.md
# Verify required fields present
head -n 10 ~/.claude/skills/my-skill/SKILL.md | grep -E "(name:|description:)"
```
Required fields:
- `name:` - Skill name
- `description:` - What it does and when to use it
### Check File Existence
```bash
# Verify SKILL.md exists
test -f ~/.claude/skills/my-skill/SKILL.md && echo "✓ SKILL.md exists" || echo "✗ SKILL.md missing"
# Check for broken references
for ref in $(grep -oE "\[.*\]\((.*\.md)\)" ~/.claude/skills/my-skill/SKILL.md | grep -oE "\(.*\.md\)" | tr -d '()'); do
if [ -f "~/.claude/skills/my-skill/$ref" ]; then
echo "✓ $ref exists"
else
echo "✗ $ref missing"
fi
done
```
### Validate Description Length
```bash
# Check description character count
desc=$(grep "description:" ~/.claude/skills/my-skill/SKILL.md | cut -d':' -f2-)
echo "Description length: ${#desc} characters (max 1024)"
if [ ${#desc} -gt 1024 ]; then
echo "⚠️ Description too long!"
fi
```
## Organizing Skill Information
### Create Skill Inventory
```bash
# Generate list of all skills with descriptions
for skill in ~/.claude/skills/*/SKILL.md; do
skill_name=$(dirname $skill | xargs basename)
description=$(grep "description:" "$skill" | cut -d':' -f2-)
echo "- **$skill_name**: $description"
done
```
### Export Skill Documentation
```bash
# Create markdown file with all skill info
{
echo "# Personal Skills Inventory"
echo ""
for skill in ~/.claude/skills/*/SKILL.md; do
echo "## $(grep "name:" $skill | cut -d':' -f2-)"
echo ""
echo "**Description**: $(grep "description:" $skill | cut -d':' -f2-)"
echo ""
echo "**Location**: $skill"
echo ""
echo "---"
echo ""
done
} > ~/skills-inventory.md
```
### Generate Skills Summary
```bash
# Count skills by location
personal_count=$(ls ~/.claude/skills/ 2>/dev/null | wc -l)
project_count=$(ls .claude/skills/ 2>/dev/null | wc -l)
echo "Skills Summary:"
echo " Personal: $personal_count"
echo " Project: $project_count"
echo " Total: $((personal_count + project_count))"
```
## Troubleshooting
### Skill Not Appearing
**Check if file exists**:
```bash
ls ~/.claude/skills/my-skill/SKILL.md
```
**Check YAML syntax**:
```bash
head -n 10 ~/.claude/skills/my-skill/SKILL.md
```
**Verify location**:
- Personal: `~/.claude/skills/skill-name/SKILL.md`
- Project: `.claude/skills/skill-name/SKILL.md`
### Cannot Read Skill File
**Check permissions**:
```bash
ls -la ~/.claude/skills/my-skill/SKILL.md
# Fix if needed
chmod 644 ~/.claude/skills/my-skill/SKILL.md
```
### Skill Directory Empty
```bash
# Check if skills directory exists
ls -la ~/.claude/skills/
# Create if missing
mkdir -p ~/.claude/skills/
```
## Best Practices
### Regular Skill Audits
Periodically review your skills:
```bash
# List all skills with last modified date
ls -lt ~/.claude/skills/*/SKILL.md
# Find skills not modified in 90 days
find ~/.claude/skills/ -name "SKILL.md" -mtime +90
```
Consider updating or removing stale skills.
### Document Your Skills
Maintain a skills inventory:
```markdown
# My Claude Code Skills
## Active Skills
- **pdf-processing**: Extract and manipulate PDFs
- **data-analysis**: Analyze CSV and Excel files
- **commit-helper**: Generate git commit messages
## Experimental
- **new-skill**: Testing new approach
## Deprecated
- **old-skill**: Replaced by new-skill
```
### Track Skill Usage
Note which skills you use frequently:
```markdown
# Skill Usage Notes
## Frequently Used
- commit-helper (daily)
- pdf-processing (weekly)
## Rarely Used
- legacy-api (consider removing)
## Never Used
- experiment-1 (delete)
```

# Updating Skills
Guidance for modifying and maintaining existing Agent Skills in Claude Code.
## Quick Update Process
### 1. Locate the Skill
```bash
# Personal skills
ls ~/.claude/skills/*/SKILL.md
# Project skills
ls .claude/skills/*/SKILL.md
# Find specific skill
find ~/.claude/skills -name "SKILL.md" -path "*/my-skill/*"
```
### 2. Edit SKILL.md
```bash
# Personal
code ~/.claude/skills/my-skill/SKILL.md
# Project
code .claude/skills/my-skill/SKILL.md
```
### 3. Apply Changes
Changes take effect the next time Claude Code starts.
**If Claude Code is already running**: Restart it to load updates.
## Common Update Scenarios
### Update Description
The description is critical for skill discovery. Update it when:
- Skill's purpose has expanded
- Trigger terms need refinement
- Usage context has changed
**Requirements**:
- Write in third person
- Include what the skill does AND when to use it
- Add specific trigger terms
- Maximum 1024 characters
**Before**:
```yaml
description: Helps with PDFs
```
**After**:
```yaml
description: Extract text and tables from PDF files, fill forms, merge documents. Use when working with PDF files or when the user mentions PDFs, forms, or document extraction.
```
### Update Instructions
When adding new features or improving clarity:
**Before** (vague):
```markdown
## Instructions
Process the data and generate output.
```
**After** (specific):
```markdown
## Instructions
1. Load data from CSV file using pandas:
```python
import pandas as pd
df = pd.read_csv('data.csv')
```
2. Clean data:
- Remove null values
- Normalize formats
- Validate ranges
3. Generate summary statistics:
```python
summary = df.describe()
```
4. Export results to Excel:
```python
summary.to_excel('output.xlsx')
```
```
### Add Examples
Examples improve skill effectiveness. Add input/output pairs:
````markdown
## Examples
**Example 1: Simple Extraction**
Input: PDF with plain text
Output:
```python
import pdfplumber
with pdfplumber.open("document.pdf") as pdf:
for page in pdf.pages:
text = page.extract_text()
print(text)
```
**Example 2: Table Extraction**
Input: PDF with tables
Output:
```python
import pdfplumber
with pdfplumber.open("tables.pdf") as pdf:
for page in pdf.pages:
tables = page.extract_tables()
for table in tables:
# Process table data
pass
```
````
### Add or Update allowed-tools
Restrict which tools Claude can use when the skill is active:
**Before** (no restrictions):
```yaml
---
name: Data Analyzer
description: Analyze data files and generate reports
---
```
**After** (read-only):
```yaml
---
name: Data Analyzer
description: Analyze data files and generate reports
allowed-tools: Read, Grep, Glob
---
```
This ensures Claude can't modify files when using this skill.
### Split Large Skills
If SKILL.md exceeds 500 lines, use progressive disclosure:
**Before** (single large file):
```markdown
# PDF Processing
## Basic Text Extraction
[100 lines of content...]
## Advanced Table Extraction
[150 lines of content...]
## Form Filling
[200 lines of content...]
## API Reference
[300 lines of content...]
```
**After** (split into multiple files):
```
pdf-processing/
├── SKILL.md # Overview and quick start
├── tables.md # Table extraction guide
├── forms.md # Form filling guide
└── reference.md # Complete API docs
```
**SKILL.md**:
```markdown
# PDF Processing
## Quick Start
[Brief overview]
## Text Extraction
[Common usage]
## Advanced Features
- **Table Extraction**: See [tables.md](tables.md)
- **Form Filling**: See [forms.md](forms.md)
- **Complete API**: See [reference.md](reference.md)
```
### Update Reference Files
When updating longer reference files (>100 lines), include a table of contents:
```markdown
# API Reference
## Contents
- Authentication and setup
- Core methods (create, read, update, delete)
- Advanced features (batch operations, webhooks)
- Error handling patterns
- Code examples
## Authentication and Setup
...
## Core Methods
...
```
## Refactoring Patterns
### Make Skills More Concise
Remove unnecessary explanations:
**Before** (too verbose):
```markdown
JSON (JavaScript Object Notation) is a data format that is commonly used
for APIs and configuration files. It uses key-value pairs and is human-readable.
To parse JSON in Python, you'll need to import the json module, which is
part of the standard library so you don't need to install anything extra.
```
**After** (concise):
```markdown
Parse JSON:
```python
import json
with open('data.json') as f:
data = json.load(f)
```
```
### Improve Terminology Consistency
**Before** (inconsistent):
```markdown
Use the API endpoint to send a request to the URL. The route will return...
The path can be accessed via the API...
```
**After** (consistent):
```markdown
Use the API endpoint to send a request. The endpoint will return...
The endpoint can be accessed via...
```
(Always use "API endpoint", never mix with "URL", "route", "path")
### Add Workflows for Complex Tasks

- [ ] Step 5: Export results
```
**Step 1: Load and validate data**
```python
import pandas as pd
df = pd.read_csv('data.csv')
assert len(df) > 0, "Data file is empty"
assert not df.isnull().all().any(), "Column has all null values"

### Add Feedback Loops
For error-prone operations:
**Before** (no validation):
```markdown
1. Make changes to config.json
2. Deploy application
3. Test in production
```
**After** (with validation loop):
```markdown
1. Make changes to config.json
2. **Validate immediately**: `python scripts/validate_config.py`
3. If validation fails:
- Review error messages
- Fix issues in config.json
- Run validation again
4. **Only proceed when validation passes**
5. Deploy to staging
6. Test in staging environment
7. Deploy to production
```
## Version Management
### Document Changes
Add a version history section to track updates:
```markdown
# My Skill
## Version History
- v2.1.0 (2025-10-16): Added batch processing support
- v2.0.0 (2025-10-01): Breaking changes to API
- v1.1.0 (2025-09-15): Added table extraction
- v1.0.0 (2025-09-01): Initial release
## Instructions
...
```
### Deprecate Features
When removing old approaches:
```markdown
## Current Method
Use the v2 API for all new integrations:
```python
from api.v2 import Client
client = Client(api_key="...")
```
## Old Patterns
<details>
<summary>Legacy v1 API (deprecated 2025-08)</summary>
The v1 API used a different client:
```python
from api.v1 import OldClient # Don't use
```
This API is no longer supported. Migrate to v2.
</details>
```
## Testing Updates
### 1. Verify YAML Syntax
After updating frontmatter:
```bash
cat SKILL.md | head -n 10
```
Check:
- Opening `---` on line 1
- Closing `---` before markdown content
- Valid YAML (no tabs, correct indentation)
- No special characters in unquoted strings
### 2. Test Description Changes
If you updated the description, test that Claude uses the skill appropriately:
Ask questions that match your new description and verify Claude activates the skill.
### 3. Check File References
If you added or renamed reference files, verify links work:
```bash
cd ~/.claude/skills/my-skill
# Check that referenced files exist
ls -l *.md
```
### 4. Verify Examples Run
If you added code examples, test them:
```bash
# Extract and run Python examples
python test_examples.py
```
## Common Update Mistakes
### ❌ Forgetting to Restart
**Problem**: Updates don't appear after editing SKILL.md
**Solution**: Restart Claude Code to load changes
### ❌ Breaking YAML Frontmatter
**Problem**: Skill stops working after update
**Check**:
```bash
cat SKILL.md | head -n 10
```
**Common issues**:
- Missing closing `---`
- Tabs instead of spaces
- Unquoted strings with colons
- Incorrect indentation
### ❌ Making Description Too Generic
**Problem**: Skill activates too often or not at all
**Before**:
```yaml
description: Helps with files
```
**After**:
```yaml
description: Analyzes log files and system metrics for performance monitoring, debugging, and diagnostics. Use when analyzing logs, system performance, or troubleshooting issues.
```
### ❌ Adding Too Much Content
**Problem**: SKILL.md becomes >500 lines
**Solution**: Use progressive disclosure:
- Keep core instructions in SKILL.md
- Move detailed content to separate reference files
- Link to reference files from SKILL.md
### ❌ Nested References
**Problem**: Claude doesn't find information in deeply nested files
**Bad** (too deep):
```markdown
# SKILL.md → references advanced.md
# advanced.md → references details.md
# details.md → has the actual info
```
**Good** (one level):
```markdown
# SKILL.md → directly references all docs
- advanced.md
- details.md
- examples.md
```
## Rollback Strategy
### Create Backup Before Major Changes
```bash
# Backup entire skill
cp -r ~/.claude/skills/my-skill ~/.claude/skills/my-skill.backup
# Or just backup SKILL.md
cp ~/.claude/skills/my-skill/SKILL.md ~/.claude/skills/my-skill/SKILL.md.backup
```
### Restore from Backup
```bash
# Restore entire skill
rm -rf ~/.claude/skills/my-skill
mv ~/.claude/skills/my-skill.backup ~/.claude/skills/my-skill
# Or just restore SKILL.md
mv ~/.claude/skills/my-skill/SKILL.md.backup ~/.claude/skills/my-skill/SKILL.md
```
### Use Version Control
For project skills (in git repositories):
```bash
# See what changed
git diff .claude/skills/my-skill/SKILL.md
# Revert changes
git checkout .claude/skills/my-skill/SKILL.md
# Commit updates
git add .claude/skills/my-skill/
git commit -m "Update my-skill: add batch processing support"
```
## Team Collaboration
### Communicate Changes
For project skills, notify team members:
```bash
git commit -m "Update PDF skill: add form filling capability
- Added form filling workflow
- Updated description to include 'forms' trigger
- Added forms.md reference guide
Team members should restart Claude Code to get updates."
git push
```
### Review Process
For shared skills, consider a review process:
1. Create feature branch
2. Update skill
3. Test thoroughly
4. Create pull request
5. Have teammate review
6. Merge when approved
7. Team members pull and restart

# Managing Snippets (v2.0)
Snippets auto-inject context when regex patterns match user messages. This skill provides a streamlined workflow for discovering snippet locations, creating snippets, searching configurations, and direct file editing.
## About Snippets
Snippets are pattern-triggered context injection files that enhance Claude's capabilities by automatically loading relevant information when specific keywords appear in user prompts. Think of them as "smart bookmarks" that activate based on what you're working on.
### What Snippets Provide
1. **Automatic context loading** - Inject relevant documentation when keywords match
2. **Workflow enhancement** - Load domain-specific guidance without manual selection
3. **Consistency** - Ensure same context is available across sessions
4. **Efficiency** - Skip manual skill invocation for frequently-used contexts
### When to Use Snippets
- Frequently-used skills that should activate on keywords (e.g., "DOCKER", "TERRAFORM")
- Domain-specific documentation that's needed for specific topics
- Quick-reference material that should load automatically
- Workflow guides tied to specific technologies or tasks
## Anatomy of a Snippet
Every snippet consists of two components:
### 1. config.local.json Entry (Required)
Located at:
```
/Users/wz/.claude/plugins/marketplaces/warren-claude-code-plugin-marketplace/claude-context-orchestrator/scripts/config.local.json
```
**Structure:**
```json
{
"name": "snippet-identifier",
"pattern": "\\b(PATTERN)\\b[.,;:!?]?",
"snippet": ["../snippets/local/category/name/SNIPPET.md"],
"separator": "\n",
"enabled": true
}
```
**Key fields:**
- `name`: Unique identifier for the snippet
- `pattern`: Regex pattern that triggers the snippet (MUST follow standard format)
- `snippet`: Array of file paths to inject (relative to config file)
- `separator`: How to join multiple files (usually `"\n"`)
- `enabled`: Whether snippet is active (`true`/`false`)
### 2. SNIPPET.md File (Required)
Located in subdirectory under:
```
/Users/wz/.claude/plugins/marketplaces/warren-claude-code-plugin-marketplace/claude-context-orchestrator/snippets/local/
```
**Structure:**
```markdown
---
name: "Descriptive Name"
description: "When to use this snippet and what it provides"
---
[Content to be injected into context]
```
**Organization:**
Snippets are organized by category:
- `snippets/local/communication/` - Email, reports, writing templates
- `snippets/local/documentation/` - Guides, references, how-tos
- `snippets/local/development/` - Code patterns, debugging workflows
- `snippets/local/productivity/` - Workflow automation, task management
- `snippets/local/output-formats/` - Formatting styles, templates
## CLI v2.0 Overview
The snippets CLI provides four focused commands:
1. **`paths`** - Discover available snippet categories and locations
2. **`create`** - Create snippets from source files with validation
3. **`list` / search** - Search snippets by name, pattern, or description
4. **`validate`** - Verify configuration integrity
**Installation:**
```bash
cd /Users/wz/.claude/plugins/.../scripts
make install # Global: uv tool install
# OR
make dev # Local dev: uv run snippets
```
**Auto-detect modes:**
- **TTY (terminal)**: Interactive selection interface
- **Non-TTY (piped)**: JSON output for scripting
## Snippet Management Process
Follow these steps in order to effectively manage snippets.
### Step 1: Discover Available Locations
Before creating a snippet, explore where snippets can be placed using the `paths` command.
**List all categories:**
```bash
snippets paths
# OR with JSON output
snippets paths --output json
```
**Filter by keyword:**
```bash
snippets paths dev # Shows categories matching "dev"
snippets paths email # Shows categories matching "email"
```
**Output:**
- Base directory path
- Category names (communication, documentation, development, productivity, output-formats)
- Category descriptions
- Full paths to each category
### Step 2: Planning the Pattern
Determine the regex pattern that will trigger your snippet. Patterns must follow the standard format (see Regex Protocol below).
**Pattern planning:**
1. List all keywords that should trigger the snippet
2. Convert to ALL CAPS (e.g., "docker" → "DOCKER")
3. Handle multi-word patterns (use `_`, `-`, or no separator)
4. Combine alternatives with `|`
5. Apply standard format: `\b(PATTERN)\b[.,;:!?]?`
**Examples:**
- Single keyword: `\b(DOCKER)\b[.,;:!?]?`
- Multiple alternatives: `\b(DOCKER|CONTAINER|DOCKERFILE)\b[.,;:!?]?`
- Multi-word: `\b(BUILD_ARTIFACT)\b[.,;:!?]?`
### Step 3: Creating a Snippet
Create snippets using the `create` command, which validates and registers the snippet automatically.
**Creation workflow:**
1. **Create source SKILL.md file with frontmatter:**
```markdown
---
name: "Docker Best Practices"
description: "Use when working with Docker containers, images, and containerization"
pattern: "\\b(DOCKER|CONTAINER|DOCKERFILE)\\b[.,;:!?]?"
---
# Docker Best Practices
[Content here...]
```
2. **Run create command:**
```bash
snippets create source.md snippets/local/development/docker/SKILL.md
# With pattern override
snippets create source.md snippets/local/development/docker/SKILL.md \
--pattern "\\b(NEW_PATTERN)\\b[.,;:!?]?"
# Force overwrite existing
snippets create source.md snippets/local/development/docker/SKILL.md --force
```
**What create does:**
1. ✅ Validates source file exists
2. ✅ Parses YAML frontmatter (name, description, pattern)
3. ✅ Validates pattern format (ALL CAPS, proper structure)
4. ✅ Validates destination is within snippets/local/
5. ✅ Extracts snippet name from destination path
6. ✅ Checks destination doesn't already exist (unless --force)
7. ✅ Creates destination directory
8. ✅ Copies file to destination
9. ✅ Registers in config.local.json automatically
**Helpful error messages:**
- Missing frontmatter → Shows required YAML structure
- Invalid pattern → Explains pattern requirements with examples
- Invalid destination → Shows expected path format
- Missing pattern → Reminds to add --pattern flag or pattern field
**Common mistakes to avoid:**
- ❌ Using lowercase in pattern
- ❌ Missing `\\b` word boundaries (requires double backslash)
- ❌ Destination outside snippets/local/ directory
- ❌ Forgetting YAML frontmatter
### Step 4: Searching and Inspecting Snippets
Search snippets using enhanced multi-level matching (name → pattern → description).
**List all snippets:**
```bash
snippets # Default: list all (TTY: interactive, piped: JSON)
snippets list # Explicit list command
snippets --output json # Force JSON output
```
**Search by keyword:**
```bash
snippets docker # Searches name, pattern, and description
snippets kubernetes # Priority: exact name > name contains > pattern > description
```
**Interactive mode (TTY):**
- Shows formatted list with match indicators
- Navigate with arrow keys
- Select to open in $EDITOR
- ESC to cancel
**Non-interactive mode (piped/JSON):**
- JSON output with match_type and match_priority
- Can pipe to jq for filtering
- Suitable for scripting
**Match priority ranking:**
1. **Exact name match** (priority 1) - `snippets mail` finds snippet named "mail"
2. **Name contains** (priority 2) - `snippets dock` finds "docker"
3. **Pattern content** (priority 3) - `snippets KUBECTL` finds patterns with KUBECTL
4. **Description match** (priority 4) - `snippets "email templates"` finds description matches
**What to check:**
- Enabled status (✓ or ✗)
- Pattern alternatives (does it cover all intended keywords?)
- File paths (do they point to correct locations?)
- Content (read SKILL.md to verify)
**Regular audits:**
- Review snippets monthly
- Disable unused snippets (edit config.local.json)
- Update patterns based on usage
- Remove outdated content
### Step 5: Updating Snippets (Direct File Editing)
**Philosophy:** v2.0 CLI focuses on search and creation. Updates are done by editing files directly.
Modify existing snippets when:
- Pattern doesn't match expected keywords
- Content is outdated
- Need to enable/disable temporarily
- Want to rename for clarity
**Update workflow:**
1. **Find the snippet:**
```bash
snippets docker # Search to locate snippet
# OR in interactive mode: select snippet → opens in $EDITOR
```
2. **Determine what needs updating:**
- **Pattern expansion** → Edit config.local.json
- **Content modification** → Edit SKILL.md directly
- **Status change** → Edit config.local.json (`enabled` field)
- **Rename** → Edit config.local.json (`name` field)
3. **For pattern updates:**
```bash
# Edit config.local.json directly
vim ~/.claude/plugins/.../scripts/config.local.json
# Modify the pattern field
{
"name": "docker",
"pattern": "\\b(DOCKER|CONTAINER|DOCKERFILE|KUBECTL)\\b[.,;:!?]?", # Added KUBECTL
...
}
```
4. **For content updates:**
```bash
# Edit SKILL.md directly
vim ~/.claude/plugins/.../snippets/local/development/docker/SKILL.md
# Update content while maintaining YAML frontmatter
```
5. **Validate changes:**
```bash
snippets validate # Check for errors
snippets validate --output json # JSON output for scripting
```
6. **Test:**
- Type trigger keyword in new prompt
- Confirm content loads correctly
**Context-aware updating:**
If a snippet failed to load during a session, analyze why:
- Did the pattern not match? → Edit config.local.json to expand pattern
- Was it disabled? → Change `"enabled": false` to `true`
- Missing keywords? → Add alternatives to pattern
### Step 6: Deleting Snippets (Direct File Editing)
Remove snippets that are:
- No longer needed
- Superseded by other snippets or skills
- Creating conflicts with other patterns
**Deletion workflow:**
1. **Backup first:**
```bash
# Create backup of config
cp ~/.claude/plugins/.../scripts/config.local.json \
~/.claude/plugins/.../scripts/config.local.json.backup.$(date +%Y%m%d_%H%M%S)
# Backup snippet file
cp -r ~/.claude/plugins/.../snippets/local/category/snippet-name \
~/.claude/plugins/.../backups/snippet-name_$(date +%Y%m%d_%H%M%S)
```
2. **Remove from config.local.json:**
```bash
vim ~/.claude/plugins/.../scripts/config.local.json
# Delete the entire mapping object
# Ensure JSON remains valid (check commas)
```
3. **Optionally delete SKILL.md:**
```bash
rm -rf ~/.claude/plugins/.../snippets/local/category/snippet-name
```
4. **Validate and verify:**
```bash
snippets validate # Check JSON is valid
snippets # Confirm snippet is gone
# Type trigger keyword → should not load
```
**Restoration:**
If you need to restore:
1. `cp backup/config.local.json.backup.TIMESTAMP config.local.json`
2. `cp -r backup/snippet-name_TIMESTAMP snippets/local/category/snippet-name`
3. `snippets validate` and test trigger keyword
## Regex Protocol (Standard Format)
**CRITICAL:** All snippet patterns MUST follow this format.
### Standard Format
```
\b(PATTERN)\b[.,;:!?]?
```
**Rules:**
1. **Word boundaries:** `\b` at start and end
2. **Parentheses:** Pattern wrapped in `()`
3. **ALL CAPS:** Uppercase only (A-Z, 0-9)
4. **Multi-word:** Use `_`, `-`, or no separator (never spaces)
5. **No mixed separators:** Can't mix `_` and `-` in same pattern
6. **Optional punctuation:** `[.,;:!?]?` at end
7. **Alternation:** Use `|` for multiple keywords
### Why Full Punctuation Matters
Users naturally add punctuation when typing. Excluding punctuation causes mismatches:
- ❌ Pattern `[.,;:]?` does NOT match "ARTIFACT!"
- ✅ Pattern `[.,;:!?]?` matches "ARTIFACT!", "ARTIFACT?", "ARTIFACT."
**Always use the full set:** `[.,;:!?]?`
### Valid Examples
```
\b(DOCKER)\b[.,;:!?]? # Single word
\b(DOCKER|CONTAINER|DOCKERFILE)\b[.,;:!?]? # Alternation
\b(BUILD_ARTIFACT)\b[.,;:!?]? # Underscore separator
\b(BUILD-ARTIFACT)\b[.,;:!?]? # Hyphen separator
\b(BUILDARTIFACT)\b[.,;:!?]? # No separator
```
### Invalid Examples
```
\b(docker)\b[.,;:!?]? # ❌ Lowercase
\b(BUILD ARTIFACT)\b[.,;:!?]? # ❌ Space separator
\b(BUILD_ART-IFACT)\b[.,;:!?]? # ❌ Mixed separators
\bDOCKER\b # ❌ Missing parens and punctuation
\b(DOCKER)\b[.,;:]? # ❌ Incomplete punctuation
```
### Pattern Transformation
User input → Standard format:
1. **Convert to ALL CAPS:**
- "docker" → "DOCKER"
- "build artifact" → "BUILD_ARTIFACT"
2. **Handle multi-word:**
- Choose one separator: `_` (preferred), `-`, or none
- Apply consistently throughout pattern
3. **Handle alternation:**
- "docker, container, dockerfile" → `(DOCKER|CONTAINER|DOCKERFILE)`
4. **Apply standard format:**
- Wrap in `\b` boundaries
- Add parentheses
- Add `[.,;:!?]?` for punctuation
### JSON Escaping
**IMPORTANT:** In config.local.json, backslashes must be doubled:
```json
{
"pattern": "\\b(DOCKER)\\b[.,;:!?]?"
}
```
Single `\b` becomes `\\b` in JSON.
## Complete Examples
### Example 1: Create Docker Snippet
**Step 1:** Understand needs
- Trigger: "docker", "container", "dockerfile"
- Provides: Docker best practices and commands
- Frequent use: Yes
**Step 2:** Plan pattern
- Keywords: DOCKER, CONTAINER, DOCKERFILE
- Pattern: `\b(DOCKER|CONTAINER|DOCKERFILE)\b[.,;:!?]?`
**Step 3:** Create snippet
1. Create directory:
```bash
mkdir -p ~/.claude/plugins/.../snippets/local/development/docker
```
2. Create SNIPPET.md:
```markdown
---
name: "Docker Best Practices"
description: "Use when working with Docker containers, images, and containerization"
---
# Docker Best Practices
[Content here...]
```
3. Add to config.local.json:
```json
{
"name": "docker",
"pattern": "\\b(DOCKER|CONTAINER|DOCKERFILE)\\b[.,;:!?]?",
"snippet": ["../snippets/local/development/docker/SNIPPET.md"],
"separator": "\n",
"enabled": true
}
```
**Step 4:** Test
- Type "DOCKER" → snippet loads
- Type "working with containers" → snippet loads
### Example 2: Update Pattern After Mismatch
**Scenario:** User typed "kubectl" but kubernetes snippet didn't load
**Step 5:** Update pattern
1. Current pattern: `\b(KUBERNETES|K8S)\b[.,;:!?]?`
2. Analysis: Missing "kubectl" keyword
3. New pattern: `\b(KUBERNETES|K8S|KUBECTL)\b[.,;:!?]?`
4. Edit config.local.json:
```json
{
"name": "kubernetes",
"pattern": "\\b(KUBERNETES|K8S|KUBECTL)\\b[.,;:!?]?",
...
}
```
5. Test: Type "kubectl" → snippet now loads
### Example 3: Delete Unused Snippet
Backup → Remove from config.local.json → Delete SNIPPET.md → Verify
## File Locations
- Config: `~/.claude/plugins/.../scripts/config.local.json`
- Snippets: `~/.claude/plugins/.../snippets/local/{category}/{name}/SNIPPET.md`
- Categories: `communication/`, `documentation/`, `development/`, `productivity/`, `output-formats/`
## Best Practices
- Check architecture first (read config.local.json before creating)
- Pattern in config.local.json, NOT YAML frontmatter
- Use ALL CAPS in patterns with full punctuation: `[.,;:!?]?`
- Double-escape in JSON: `\\b` not `\b`
- Test after changes
- Backup before deletion
## Quick Reference (v2.0)
| Task | Command / Action |
|------|------------------|
| **Discover categories** | `snippets paths` or `snippets paths <filter>` |
| **Create snippet** | `snippets create source.md snippets/local/category/name/SKILL.md` |
| **List all snippets** | `snippets` or `snippets list` |
| **Search snippets** | `snippets <keyword>` (searches name/pattern/description) |
| **Update pattern** | Edit `pattern` field in config.local.json directly |
| **Update content** | Edit SKILL.md file directly (or use `snippets <name>` in TTY → opens $EDITOR) |
| **Enable/disable** | Change `enabled` field in config.local.json |
| **Delete snippet** | 1. Backup files<br>2. Remove from config.local.json<br>3. Delete SKILL.md directory |
| **Validate config** | `snippets validate` or `snippets validate --output json` |
| **Test pattern** | Type trigger keyword in new prompt |
## Troubleshooting
| Issue | Fix |
|-------|-----|
| Not loading | Check `enabled: true`, pattern matches (ALL CAPS), file path correct |
| Pattern not matching | Verify standard format, use `[.,;:!?]?`, test with ALL CAPS |
| Too many loading | Check overlapping patterns, disable conflicts |
| JSON errors | Validate syntax, use `\\b` not `\b` |
## Critical Reminders
**Architecture:**
- Pattern goes in config.local.json (NOT YAML frontmatter)
- Always read config.local.json before creating snippets
- Double-escape in JSON: `\\b`
**When User Corrects You:**
Stop → Read actual files → Understand architecture → Fix all related mistakes → Verify

name: pdftext
description: Extract text from PDFs for LLM consumption using AI-powered or traditional tools. Use when converting academic PDFs to markdown, extracting structured content (headers/tables/lists), batch processing research papers, preparing PDFs for RAG systems, or when mentions of "pdf extraction", "pdf to text", "pdf to markdown", "docling", "pymupdf", "pdfplumber" appear. Provides Docling (AI-powered, structure-preserving, 97.9% table accuracy) and traditional tools (PyMuPDF for speed, pdfplumber for quality). All processing is on-device with no API calls.

# PDF Text Extraction
## Tool Selection
| Tool | Speed | Quality | Structure | Use When |
|------|-------|---------|-----------|----------|
| **Docling** | 0.43s/page | Good | ✓ Yes | Need headers/tables/lists, academic PDFs, LLM consumption |
| **PyMuPDF** | 0.01s/page | Excellent | ✗ No | Speed critical, simple text extraction, good enough quality |
| **pdfplumber** | 0.44s/page | Perfect | ✗ No | Maximum fidelity needed, slow acceptable |
**Decision:**
- Academic research → Docling (structure preservation)
- Batch processing → PyMuPDF (60x faster)
- Critical accuracy → pdfplumber (0 quality issues)
## Installation
```bash
# Create virtual environment
python3 -m venv pdf_env
source pdf_env/bin/activate
# Install Docling (AI-powered, recommended)
pip install docling
# Install traditional tools
pip install pymupdf pdfplumber
```
**First run downloads ML models** (~500MB-1GB, cached locally, no API calls).
## Basic Usage
### Docling (Structure-Preserving)
```python
from docling.document_converter import DocumentConverter
converter = DocumentConverter() # Reuse for multiple PDFs
result = converter.convert("paper.pdf")
markdown = result.document.export_to_markdown()
# Save output
with open("paper.md", "w") as f:
f.write(markdown)
```
**Output includes:** Headers (##), tables (|...|), lists (- ...), image markers.
### PyMuPDF (Fast)
```python
import fitz
doc = fitz.open("paper.pdf")
text = "\n".join(page.get_text() for page in doc)
doc.close()
with open("paper.txt", "w") as f:
f.write(text)
```
### pdfplumber (Highest Quality)
```python
import pdfplumber
with pdfplumber.open("paper.pdf") as pdf:
text = "\n".join(page.extract_text() or "" for page in pdf.pages)
with open("paper.txt", "w") as f:
f.write(text)
```
## Batch Processing
See `examples/batch_convert.py` for ready-to-use script.
**Pattern:**
```python
from pathlib import Path
from docling.document_converter import DocumentConverter
converter = DocumentConverter() # Initialize once
for pdf in Path("./pdfs").glob("*.pdf"):
result = converter.convert(str(pdf))
markdown = result.document.export_to_markdown()
Path(f"./output/{pdf.stem}.md").write_text(markdown)
```
**Performance tip:** Reuse converter instance. Reinitializing wastes time.
## Quality Considerations
**Common issues:**
- Ligatures: `/uniFB03` → "ffi" (post-process with regex)
- Excessive whitespace: 50-90 instances (Docling has fewer)
- Hyphenation breaks: End-of-line hyphens may remain
**Quality metrics script:** See `examples/quality_analysis.py`
**Benchmarks:** See `references/benchmarks.md` for enterprise production data.
## Troubleshooting
**Slow first run:** ML models downloading (15-30s). Subsequent runs fast.
**Out of memory:** Reduce concurrent conversions, process large PDFs individually.
**Missing tables:** Ensure `do_table_structure=True` in Docling options.
**Garbled text:** PDF encoding issue. Apply ligature fixes post-processing.
## Privacy
**All tools run on-device.** No API calls, no data sent externally. Docling downloads models once, caches locally (~500MB-1GB).

## Benchmark Methodology
### Speed Testing
```python
import time
start = time.time()
result = converter.convert(pdf_path)
elapsed = time.time() - start
per_page = elapsed / page_count
```
### Quality Testing
```python
# Count quality issues
consecutive_spaces = len(re.findall(r' +', text))
excessive_newlines = len(re.findall(r'\n{4,}', text))
control_chars = len(re.findall(r'[\x00-\x08\x0b\x0c\x0e-\x1f]', text))
garbled_chars = len(re.findall(r'[<5B>\ufffd]', text))
total_issues = consecutive_spaces + excessive_newlines + control_chars + garbled_chars
```
### Structure Testing
```python
# Count markdown elements
headers = len(re.findall(r'^#{1,6}\s+.+$', markdown, re.MULTILINE))
tables = len(re.findall(r'\|.+\|', markdown))
lists = len(re.findall(r'^\s*[-*]\s+', markdown, re.MULTILINE))
```

# PDF Extraction Quality Metrics
## Key Metrics
### 1. Consecutive Spaces
**What:** Multiple spaces in sequence (2+)
**Pattern:** ` +`
**Impact:** Formatting artifacts, token waste
**Good:** < 50 occurrences
**Bad:** > 100 occurrences
### 2. Excessive Newlines
**What:** 4+ consecutive newlines
**Pattern:** `\n{4,}`
**Impact:** Page breaks treated as whitespace
**Good:** < 20 occurrences
**Bad:** > 50 occurrences
### 3. Control Characters
**What:** Non-printable characters
**Pattern:** `[\x00-\x08\x0b\x0c\x0e-\x1f]`
**Impact:** Parsing errors, display issues
**Good:** 0 occurrences
**Bad:** > 0 occurrences
### 4. Garbled Characters
**What:** Replacement characters (<28>)
**Pattern:** `[<5B>\ufffd]`
**Impact:** Lost information, encoding failures
**Good:** 0 occurrences
**Bad:** > 0 occurrences
### 5. Hyphenation Breaks
**What:** End-of-line hyphens not joined
**Pattern:** `\w+-\n\w+`
**Impact:** Word splitting affects search
**Good:** < 10 occurrences
**Bad:** > 50 occurrences
### 6. Ligature Encoding
**What:** Special character combinations
**Examples:** `/uniFB00` (ff), `/uniFB01` (fi), `/uniFB03` (ffi)
**Impact:** Search failures, readability
**Fix:** Post-process with regex replacement
## Quality Score Formula
```python
total_issues = (
consecutive_spaces +
excessive_newlines +
control_chars +
garbled_chars
)
quality_score = garbled_chars * 10 + total_issues
# Lower is better
```
**Ranking:**
- Excellent: < 10 score
- Good: 10-50 score
- Fair: 50-100 score
- Poor: > 100 score
## Analysis Script
```python
import re
def analyze_quality(text):
"""Analyze PDF extraction quality."""
return {
'chars': len(text),
'words': len(text.split()),
'consecutive_spaces': len(re.findall(r' +', text)),
'excessive_newlines': len(re.findall(r'\n{4,}', text)),
'control_chars': len(re.findall(r'[\x00-\x08\x0b\x0c\x0e-\x1f]', text)),
'garbled_chars': len(re.findall(r'[<5B>\ufffd]', text)),
'hyphen_breaks': len(re.findall(r'\w+-\n\w+', text))
}
# Usage
text = open("extracted.txt").read()
metrics = analyze_quality(text)
print(f"Quality score: {metrics['garbled_chars'] * 10 + metrics['consecutive_spaces'] + metrics['excessive_newlines']}")
```
## Test Results (90-page Academic PDF)
| Tool | Total Issues | Garbled | Quality Score | Rating |
|------|--------------|---------|---------------|--------|
| pdfplumber | 0 | 0 | 0 | Excellent |
| PyMuPDF | 1 | 0 | 1 | Excellent |
| Docling | 50 | 0 | 50 | Good |
| pdftotext | 90 | 0 | 90 | Fair |
| pdfminer | 45 | 0 | 45 | Good |
| pypdf | 120 | 5 | 170 | Poor |
## Content Completeness
### Phrase Coverage Analysis
Extract 3-word phrases from each tool's output:
```python
def extract_phrases(text):
words = re.findall(r'\b[a-zA-Z]+\b', text.lower())
return {' '.join(words[i:i+3]) for i in range(len(words)-2)}
common = set.intersection(*[extract_phrases(t) for t in texts.values()])
```
**Results:**
- Common phrases: 10,587 (captured by all tools)
- Docling unique: 17,170 phrases (most complete)
- pdfplumber unique: 8,229 phrases (conservative)
## Cleaning Strategies
### Fix Ligatures
```python
def fix_ligatures(text):
"""Fix PDF ligature encoding."""
replacements = {
r'/uniFB00': 'ff',
r'/uniFB01': 'fi',
r'/uniFB02': 'fl',
r'/uniFB03': 'ffi',
r'/uniFB04': 'ffl',
}
for pattern, repl in replacements.items():
text = re.sub(pattern, repl, text)
return text
```
### Normalize Whitespace
```python
def normalize_whitespace(text):
"""Clean excessive whitespace."""
text = re.sub(r' +', ' ', text) # Multiple spaces → single
text = re.sub(r'\n{4,}', '\n\n\n', text) # Many newlines → max 3
return text.strip()
```
### Join Hyphenated Words
```python
def join_hyphens(text):
"""Join end-of-line hyphenated words."""
return re.sub(r'(\w+)-\s*\n\s*(\w+)', r'\1\2', text)
```

# Pedagogical Journey
Explain solutions through discovery—showing **how insights emerged** rather than exhaustive technical details.
## Core Principle
Show the journey of discovery without exhaustion. Focus on the "why" rather than the "what", highlighting key insights and decision points.
## Required Sections
Every explanation MUST include:
### 1. High-Level Summary (2-3 sentences)
Start with a concise overview of what was accomplished. Focus on the "what" and "why" before the "how".
### 2. The Journey & Discovery Process (2-4 sentences)
Brief context on how the solution emerged:
- What led to the approach taken
- Key insights or turning points during implementation
- Alternative approaches considered (if relevant)
- How testing or debugging shaped the final solution
**Examples:**
- "Initially I tried X, but discovered Y limitation which led to the current Z approach"
- "The key insight came from noticing [pattern/behavior], which informed..."
- "During testing, I found [issue], which revealed the need for..."
Keep this concise—focus on the most impactful decision points.
## Optional Sections
Include when they add value:
### 3. Visual Overview
Diagrams clarifying understanding: architecture diagrams, flow charts, file structure trees, sequence diagrams.
**Skip if:** Explanation is simple enough without visuals or words suffice.
### 4. Key Changes
Organize changes by module/component, purpose, and impact.
**Skip if:** Change is isolated to one component or already covered in Journey section.
### 5. Technical Details
Implementation specifics: new functions/classes, modified behavior (before/after), integration points.
**Important**: Don't include full code listings—reference file paths and line numbers instead (e.g., `tracking.lua:45`).
**Skip if:** Implementation is straightforward or user didn't ask for deep technical details.
### 6. What to Try Next
2-3 concrete suggestions for testing, building, or exploring further.
**Skip if:** No clear next steps or user didn't ask for guidance.
## Format-Specific Guidelines
### As HTML
1. Summary + Journey at top (required, always visible)
2. Other sections only if they add value
3. Use Mermaid flowcharts for decision trees
4. Collapsible sections for technical details
5. Color coding: Gold for insights, Green for outcomes, Gray for details
### As Markdown
1. Use standard headers (`##`, `###`)
2. Use `> **Journey Insight:**` blockquotes for key discoveries
3. Use mermaid code fences for diagrams
4. Use tables for before/after comparisons
5. Only include optional sections when valuable
## Section Selection Logic
**Always include:**
- ✅ High-Level Summary
- ✅ The Journey & Discovery Process
**Consider including when:**
- 📊 Visual Overview: Complex architecture, multiple components, or process flows
- 🔧 Key Changes: Multiple modules modified or changes span different layers
- ⚙️ Technical Details: Non-trivial implementation or user specifically asked
- 🚀 What to Try Next: Clear actionable next steps or areas to explore
**Skip optional sections when:**
- ❌ Information already covered in required sections
- ❌ Change is simple and self-explanatory
- ❌ Would add noise without adding clarity
- ❌ User didn't express interest in that level of detail
## General Guidelines
- **Be intentionally concise**: Aim for clarity over completeness
- **Show the journey, don't narrate every step**: Highlight key discoveries and decision points
- **Connect decisions to outcomes**: Help users understand why choices were made
- **Use formatting liberally**: Headers, bullets, bold text for scanning
- **Avoid walls of text**: Break up long sections with whitespace
- **Adapt to format**: Use format-specific features to enhance clarity
## Minimal Example
```
I've fixed the popup issue where they were closing immediately after opening.
**How we got here:**
Initially I suspected the popup code itself, but debugging revealed the CursorMoved autocommand was closing popups globally. The fix adds a buffer name check to only close popups when cursor moves in source files, not within the popup itself.
```
## Format Combinations
You can combine this with other output formats:
- "EXPLAIN HTML" → Use this structure in HTML format
- "EXPLAIN markdown" → Use this structure in markdown
- "EXPLAIN + [another format]" → Apply both modes together
For detailed examples and advanced patterns, see [reference.md](reference.md).

# Pedagogical Journey - Advanced Reference
Detailed patterns, examples, and format-specific guidelines for creating journey-focused explanations.
## Format-Specific Guidelines
### EXPLAIN as HTML
When combining with HTML format:
**1. Structure Mapping:**
- **Summary** → `.important-always-visible` or `.primary-section` [REQUIRED]
- **Journey** → `.card.priority` with gold border [REQUIRED]
- **Visual** → Mermaid diagrams in `.diagram-container` [OPTIONAL]
- **Key Changes** → `.two-column-layout` for side-by-side comparison [OPTIONAL]
- **Technical Details** → `.collapsible` (closed by default) [OPTIONAL]
- **What to Try Next** → `.card` with action items [OPTIONAL]
**2. Progressive Disclosure:**
- Summary and Journey always visible at top (REQUIRED)
- Other sections only if they add value
- Technical details in collapsible sections
- Color coding: Gold for insights, Green for outcomes, Gray for details
**3. Visual Enhancement:**
- Use Mermaid flowcharts to show decision trees ("tried X → discovered Y → chose Z")
- Timeline diagrams for implementation journey
- Before/after comparison diagrams
**4. Workflow:**
1. Read base template: `${CLAUDE_PLUGIN_ROOT}/templates/html/base-template.html`
2. Write to: `claude_html/explanation_{topic}.html`
3. Edit to add pedagogical-journey-structured content
4. Include required sections + relevant optional ones
5. Open with `open` command
### EXPLAIN as Markdown
When using markdown format:
1. Use standard markdown headers (`##`, `###`) for sections
2. Use `> **Journey Insight:**` blockquotes for key discoveries
3. Use mermaid code fences for diagrams (if Visual section included)
4. Use tables for before/after comparisons (if Key Changes included)
5. Use task lists for "What to Try Next"
6. **Only include optional sections when they're valuable**
### EXPLAIN as Plain Text
When using plain text:
1. Use clear section separators (`===`, `---`)
2. Use indentation to show hierarchy
3. Use ASCII art or structured lists for visualizations
4. Keep it simple and scannable
5. Focus on required sections, add optional ones sparingly
## Full Example: EXPLAIN as HTML
```
[.important-always-visible]
I've implemented X to solve Y problem. This involved modifying A and B components, and adding new C functionality.
[.card.priority with gold border]
**How we got here:**
Initially the CursorMoved autocmd was closing popups globally. Testing revealed this was the root cause - popups were created successfully but closed immediately. The fix checks if we're inside the popup before closing.
[Mermaid flowchart - OPTIONAL, included because it clarifies decision logic]
CursorMoved triggered → Check buffer name → Is it popup? → Yes: Keep open / No: Close
[.two-column-layout - OPTIONAL, included because there's a before/after comparison]
**Key Changes:**
| Before | After |
|--------|-------|
| Popup closes on ANY cursor move | Popup stays open when cursor in popup |
| Global autocommand | Buffer-aware check |
[.collapsible closed - OPTIONAL, included because user might want implementation details]
**Technical Details:**
The implementation works by checking buffer names in the CursorMoved callback. The decision to use buffer name matching came from the constraint that popup buffers have predictable names. You can see this in action at init.lua:232 and popup.lua:338.
[.card - OPTIONAL, included because there are actionable next steps]
**Try it out:**
1. Test with: Press <leader>aa on an annotation
2. Explore: Try moving cursor within popup vs outside
3. Ask me about: Why buffer names vs window IDs?
```
## Full Example: EXPLAIN as Markdown
```markdown
# Implementation Summary
I've implemented X to solve Y problem. This involved modifying A and B components, and adding new C functionality.
## How We Got Here
Initially the CursorMoved autocmd was closing popups globally. Testing revealed this was the root cause - popups were created successfully but closed immediately.
> **Journey Insight:** The key breakthrough came from realizing that the popup buffer has a predictable name pattern, which we could use to distinguish it from regular buffers.
The fix checks if we're inside the popup before closing, adding a buffer name check to only close popups when cursor moves in source files.
## Decision Logic
```mermaid
graph TD
A[CursorMoved triggered] --> B{Check buffer name}
B -->|Is popup?| C[Keep open]
B -->|Is source?| D[Close]
```
## Key Changes
| Aspect | Before | After |
|--------|--------|-------|
| Behavior | Popup closes on ANY cursor move | Popup stays open when cursor inside |
| Implementation | Global autocommand | Buffer-aware check |
| Reliability | Unreliable for nested UIs | Works with complex UIs |
## Technical Details
<details>
<summary>Click to expand implementation details</summary>
The implementation works by checking buffer names in the CursorMoved callback. The decision to use buffer name matching came from the constraint that popup buffers have predictable names.
You can see this in action at:
- `init.lua:232` - Autocommand registration
- `popup.lua:338` - Buffer name check logic
The buffer name pattern is: `popup_*_buffer`
</details>
## What to Try Next
- [ ] Test with: Press <leader>aa on an annotation
- [ ] Explore: Try moving cursor within popup vs outside
- [ ] Ask: Why buffer names vs window IDs?
```
## Journey Insight Examples
How to highlight key discoveries in your explanations:
### Example 1: Implementation Discovery
```
Initially I tried X, but discovered Y limitation which led to the current Z approach.
```
### Example 2: Pattern Recognition
```
The key insight came from noticing [pattern/behavior], which informed the entire refactoring.
```
### Example 3: Testing-Driven Discovery
```
During testing, I found [issue], which revealed the need for a more robust approach.
```
### Example 4: Architecture Realization
```
After implementing the first version, I realized [constraint], which led us to adopt [new pattern].
```
## Section Balance Guide
### When to Include Each Optional Section
**Visual Overview** - Include when:
- You're explaining architecture changes (show with diagrams)
- Multiple components interact (flowchart helps)
- File structure significantly changed (tree diagram)
- Process flow isn't obvious (sequence diagram)
- The system is genuinely complex
**Key Changes** - Include when:
- More than one component was modified
- Changes span multiple layers/domains
- User needs to understand scope
- Before/after comparison adds clarity
**Technical Details** - Include when:
- Implementation is non-trivial
- User specifically asked for deep details
- Design decisions need explanation
- Integration points are complex
**What to Try Next** - Include when:
- There are clear testing steps
- Natural follow-up work exists
- User might want to build on changes
- Areas to explore are obvious
## Common Pitfalls to Avoid
### ❌ Too Exhaustive
```
The journey was: I started with approach A, then tried B, then C,
then considered D, then revisited A...
```
✅ **Better:**
```
Initially I tried approach A, but discovered it didn't scale. This led
to the current approach B which handles the edge case better.
```
### ❌ Missing the Journey
```
I modified file X and file Y. File X now has function Z.
```
✅ **Better:**
```
Testing revealed that the original single-file approach created
tight coupling. Splitting into X and Y decouples the concerns.
```
### ❌ Too Technical Without Context
```
Modified CursorMoved autocommand callback to check buffer name patterns.
```
✅ **Better:**
```
The CursorMoved autocommand was closing popups globally. Testing showed
that checking the buffer name lets us distinguish popups from regular
windows—popups stay open, source windows close.
```
### ❌ Unnecessary Details
```
First I created 47 test cases covering 12 edge cases. Then I ran
the test suite which took 3 minutes and 42 seconds...
```
✅ **Better:**
```
Testing revealed an edge case where nested popups would interfere.
This led to the buffer-aware approach that isolates popup state.
```
## Best Practices Summary
- **Concise**: 2-4 sentences for journey, not paragraphs
- **Connected**: Link each insight to the final solution
- **Concrete**: Use specific examples (not "edge cases", but "nested popups")
- **Clear**: Explain the "why" not every "how"
- **Candid**: Show what you tried that didn't work
- **Curious**: Leave room for follow-up questions
## Minimal vs. Full
### Minimal (Required Sections Only)
Use when:
- The change is straightforward
- User is in a hurry
- The journey is simple
- No complex dependencies
```
I've fixed the popup issue where they were closing immediately after opening.
**How we got here:**
Initially I suspected the popup code itself, but debugging revealed the
CursorMoved autocommand was closing popups globally. The fix adds a
buffer name check to only close popups when cursor moves in source files,
not within the popup itself.
```
### Full (All Sections)
Use when:
- Multiple components changed
- Architecture decision was significant
- User wants to understand deeply
- There are clear next steps
Use the full example in the previous section as a template.
---
**Remember**: This is an invitation for dialogue. Show the journey of discovery without making it exhaustive. Include only sections that genuinely enhance understanding. Keep explanations accessible and leave room for curiosity.

# Library Research Guide
Quick reference for researching and selecting libraries during prototyping.
## Search Strategy Flowchart
```
Need feature X?
↓
1. Can I build it in < 30 lines?
→ YES: Don't use library
→ NO: Continue to step 2
↓
2. Search for solutions
- WebSearch: "best [feature] library [framework] 2025"
- Exa Code: "[framework] [feature] implementation examples"
↓
3. Found 2-3 candidates?
→ Compare them (see criteria below)
↓
4. Test the top choice
→ Works in < 15 min? Use it
→ Too complex/broken? Try next option
↓
5. Still nothing good?
→ Build it yourself
→ Or simplify the requirement
```
## Evaluation Criteria
### Quick Check (2 min per library)
```bash
# For npm packages
npm info <package-name>
Look for:
✅ Last publish: < 6 months ago
✅ Weekly downloads: > 10k (for popular features)
✅ Dependencies: < 10 (fewer is better)
✅ License: MIT or Apache 2.0
✅ TypeScript: Built-in types or @types/ available
❌ Warning signs:
- Last publish > 1 year ago
- Many open issues, few closed
- "deprecated" in description
- Requires lots of peer dependencies
```
### Deep Check (5 min if quick check passes)
```bash
# Check GitHub
1. Stars: > 1k for common features
2. Issues:
- Response rate (maintainer active?)
- Closed/Open ratio (> 2:1 good)
3. Last commit: < 3 months ideal
4. Contributors: > 5 (not single-maintainer)
5. Examples/demos: Exist and work?
```
### Bundle Size Check
```
Visit: https://bundlephobia.com/package/<package-name>
Acceptable sizes for prototypes:
- Utilities: < 10kb
- UI components: < 50kb
- Full editors: < 500kb
- Anything else: Question if you need it
```
## Common Feature Searches
### Rich Text / Markdown Editor
```bash
# Search queries
"react markdown editor wysiwyg 2025"
"best markdown editor component [framework]"
"lightweight rich text editor [framework]"
# What to look for
- Live preview support
- Custom toolbar options
- Export/import formats
- Syntax highlighting
# Alternatives to consider
- Full WYSIWYG editor (heavy)
- Markdown editor with preview (medium)
- Plain textarea with preview (light)
- CodeMirror / Monaco (code-focused)
```
### Diff Viewer
```bash
# Search queries
"visual diff component [framework]"
"side by side diff viewer [framework]"
"git diff ui component"
# What to look for
- Split/unified view toggle
- Line highlighting
- Syntax highlighting
- Word-level diffs
# Fallback
- Use a diffing algorithm library
- Render with custom CSS
```
### State Management
```bash
# Search queries
"[framework] state management 2025"
"zustand vs redux vs context"
"when to use state management library"
# Decision tree
- Simple app (< 5 components) → useState/useReducer
- Medium app (5-20 components) → Context API or Zustand
- Complex app (20+ components) → Redux Toolkit or Recoil
# For prototypes: Start simple, add later if needed
```
### Form Handling
```bash
# Search queries
"[framework] form library 2025"
"react hook form vs formik"
"form validation library"
# Decision tree
- Simple forms (1-3 fields) → Vanilla HTML + state
- Medium forms (4-10 fields) → Controlled components
- Complex forms (10+ fields, validation) → React Hook Form / Formik
# For prototypes: Keep it vanilla, add library if > 10 fields
```
### Data Fetching
```bash
# Search queries
"[framework] data fetching library"
"react query vs swr vs apollo"
"best way to fetch data [framework]"
# Decision tree
- Simple REST API → fetch / axios
- Need caching/refetching → React Query / SWR
- GraphQL → Apollo Client / urql
# For prototypes: Start with fetch, add library if you need:
- Automatic refetching
- Cache management
- Optimistic updates
```
### Styling
```bash
# Search queries
"[framework] css framework 2025"
"tailwind vs styled-components vs css modules"
"css-in-js vs css modules"
# Decision tree
- Prototype (speed matters) → Vanilla CSS or inline styles
- Need consistency → CSS Modules or Tailwind
- Component library → Styled Components / Emotion
- Design system → Material-UI / Ant Design
# For prototypes: Vanilla CSS first, add framework if needed
```
## Search Query Templates
### General Pattern
```
"best [feature-type] library for [framework] [year]"
"[specific-library] vs [alternative] comparison"
"[feature-type] implementation [framework] example"
"lightweight [feature-type] component [framework]"
```
### For Code Examples
Use exa-code search:
```
"[framework] [feature] implementation example"
"how to use [library-name] with [framework]"
"[feature] tutorial [framework]"
```
### For Comparisons
```
"[library-a] vs [library-b] [year]"
"[library-name] alternatives"
"[library-name] reddit" (real user opinions)
"[library-name] bundle size"
```
## Red Flags
### In Search Results
- Many "how to fix" articles
- Lots of open issues on GitHub
- Tutorials only from > 2 years ago
- No clear documentation site
- Only works with specific versions
### In Documentation
- No getting started guide
- No examples
- Assumes lots of prior knowledge
- Inconsistent API
- Breaking changes in minor versions
### In Issues/Community
- Maintainer unresponsive
- Many unanswered questions
- Lots of "this doesn't work" issues
- People asking for alternatives
- Security issues ignored
## Decision Making
### Use native/simple if:
```javascript
// ❌ Don't import library for
- Date formatting (Intl.DateTimeFormat)
- HTTP requests (fetch API)
- Simple state (useState/useReducer)
- Basic validation (HTML5 + regex)
- Simple animations (CSS transitions)
```
### Use library if:
```javascript
// ✅ Consider library for
- Complex parsing (markdown, CSV)
- Diffing algorithms
- Rich text editing
- Code highlighting
- Complex animations
- Data visualization
```
## Research Time Budgets
- **Quick feature** (< 30 min to build): 0 min research → build it
- **Medium feature** (30 min - 2 hours): 10 min research → decide
- **Complex feature** (> 2 hours): 20 min research → pick best tool
If research takes > 20 minutes, you're overthinking it:
- Pick the most popular option
- Try it for 15 minutes
- If it doesn't work, try alternative
## Example Research Session
**Scenario**: Need visual diff for markdown editor
**Step 1: Initial search** (3 min)
```bash
WebSearch: "react visual diff component side by side"
Results:
- react-diff-viewer (6.2k stars)
- react-diff-view (3.1k stars)
- monaco-diff-editor (part of Monaco)
```
**Step 2: Quick comparison** (5 min)
```bash
npm info react-diff-viewer
# Last publish: 8 months ago (okay)
# Downloads: 45k/week (popular)
# Dependencies: 4 (good)
npm info react-diff-view
# Last publish: 1 year ago (warning)
# Downloads: 8k/week (less popular)
# Dependencies: 3 (good)
Monaco: Heavy (500kb+), overkill for simple diff
```
**Step 3: Check examples** (2 min)
- react-diff-viewer: Has live demo, looks good
- react-diff-view: Examples look more complex
**Decision**: Try react-diff-viewer first (most popular, good docs)
**Step 4: Test** (10 min)
```bash
npm install react-diff-viewer
# Create test component
# Works in 10 min → Keep it
```
**Total time**: 20 minutes from "need diff viewer" to "working implementation"
## Remember
> "Perfect is the enemy of good. Pick something reasonable and move forward. You can always swap libraries later if needed."
The goal is **working software**, not the perfect tech stack. Spend 80% of time building, 20% researching.

# Rapid Full-Stack Prototyping
Build working full-stack web apps quickly (1-4 hours). Design first, code second, test third.
## When to Use
- User says "WEBAPP", "PROTOTYPE", "full-stack app", or "build a web application"
- Need both backend API + frontend UI
- Want speed + quality
## What You'll Build
- **Stack**: React + Vite + RESTful API (FastAPI/Express) + SQLite
- **Timeline**: 1-4 hours from idea to working app
- **Output**: Polished, functional prototype with keyboard shortcuts and clean UI
## The 3-Step Process
### Step 1: Design (5-10 min)
Create a text-based design showing:
```
UI LAYOUT:
[Header with Logo, Nav, Actions]
[Main Content - Left Sidebar | Center Panel | Right Info]
[Footer with Status]
USER INTERACTIONS:
1. Click "New" → Opens editor
2. Type text → Updates state
3. Press ⌘S → Saves via API
4. Click "History" → Opens panel
DATA MODELS:
- Item: {id, content, created_at}
- Revision: {id, item_id, content, timestamp}
API ENDPOINTS:
GET /api/items → List all
POST /api/items → Create new
GET /api/items/:id → Get one
PUT /api/items/:id → Update
GET /api/history/:id → Get revisions
```
### Step 2: Get Approval (30 sec)
Show the design → User says "looks good" → Start coding
### Step 3: Build (1-3 hours)
Use this stack (don't ask, just use):
- **Frontend**: React + Vite
- **Backend**: FastAPI (Python) or Express (Node)
- **Database**: SQLite
- **State**: useState + useEffect
Build in order:
1. Backend skeleton (30 min)
2. Core features (1-2 hours)
3. Polish + keyboard shortcuts (30 min)
4. Test with WEBTEST
---
## Rules for Claude
✅ **DO:**
- Design mock UI before any code
- Use React + RESTful API (default)
- Start coding immediately after approval
- Add keyboard shortcuts (⌘S, ⌘/, etc.)
❌ **DON'T:**
- Ask user to choose frameworks
- Skip the design phase
- Spend 30+ min researching simple features
- Build custom solutions for standard problems
## Core Principles
1. **Design Before Code** - Mock UI + interactions first, then build
2. **Use What You Know** - Familiar tools > "perfect" tools you don't know
3. **Single Source of Truth** - One state for each piece of data, sync explicitly
4. **Right Tool for Job** - Fighting a component's design? Wrong component
5. **Test Early** - Automated tests + real user feedback before launch
## Default Stack (Use This)
```
Frontend: React + Vite
Backend: FastAPI (Python) or Express (Node)
Database: SQLite
State: useState + useEffect
Styling: Vanilla CSS
```
**Why?** Fast setup, familiar patterns, good docs, zero config database.
**When to deviate:**
- User explicitly requests different stack → use their choice
- User needs SEO/SSR → use Next.js instead of Vite
- User says "no code" → suggest Bubble/Retool (explain trade-offs)
## Choosing Libraries
**When to add a library:**
- ✅ Would take > 1 hour to build from scratch
- ✅ Well-maintained (updated in last 6 months)
- ✅ You need > 30% of its features
**When to build it yourself:**
- ✅ Can be done in < 30 lines of code
- ✅ Only need 10% of library features
- ✅ Fighting the library's design
**Quick research (spend max 15 min):**
```bash
# 1. Search
WebSearch: "best [feature] library react 2025"
# 2. Check npm
npm info [package-name]
# Look at: downloads/week, last publish, dependencies count
# 3. Test
# Try basic example - works in 15 min? Keep it. Doesn't? Try next option.
```
**Examples:**
```javascript
// ❌ Don't need library for:
fetch() // axios is overkill
<textarea /> // don't force WYSIWYG when plain text works
Intl.DateTimeFormat // moment.js is heavy
// ✅ Use library for:
<MarkdownEditor /> // complex parsing + preview
<DiffViewer /> // diff algorithm is non-trivial
<CodeEditor /> // syntax highlighting + LSP
```

```
## Build Workflow
### Phase 0: Design (15-30 min)
See "The 3-Step Process" above - create text-based design with UI layout, interactions, data models, and API endpoints. Show to user → get approval → start coding.
### Phase 1: Backend + Frontend Skeleton (30 min)
**Backend:**
```python
# Define models → Create CRUD endpoints → Test with curl
# FastAPI example:
@app.get("/api/items")
async def list_items(): ...
@app.post("/api/items")
async def create_item(item: Item): ...
```
**Frontend:**
```bash
npm create vite@latest my-app -- --template react
cd my-app && npm install
# Configure vite.config.js proxy to backend
# Test connection with /api/health endpoint
```
### Phase 2: Core Features (1-2 hours)
- Build one feature at a time
- useState for local state, useEffect for side effects
- Single source of truth (one canonical state, sync others from it)
- Test each feature before moving to next
### Phase 3: Polish (30 min)
```javascript
// Add keyboard shortcuts
useEffect(() => {
const handleKeyDown = (e) => {
if (e.metaKey) {
if (e.key === 's') { e.preventDefault(); save(); }
if (e.key === '/') { e.preventDefault(); showHelp(); }
}
};
window.addEventListener('keydown', handleKeyDown);
return () => window.removeEventListener('keydown', handleKeyDown);
}, []);
```
- Add help modal (⌘/)
- Add button active states
- Add status feedback ("✓ Saved")
- Add tooltips with keyboard shortcuts
### Phase 4: Test (Use WEBTEST)
```bash
# Run automated tests
WEBTEST # Triggers testing-webapps skill
# Manual checks:
# - All buttons work
# - Data persists after save
# - No console errors
# - Keyboard shortcuts work
```
## Common Mistakes
### 1. Multiple Sources of Truth
```javascript
// ❌ Bad: Three states for same data
const [editorContent, setEditorContent] = useState('');
const [diffContent, setDiffContent] = useState('');
const [previewContent, setPreviewContent] = useState('');
// ✅ Good: One source, sync to views
const [content, setContent] = useState('');
useEffect(() => {
editorRef.current?.setContent(content);
}, [viewMode, content]);
```
### 2. Fighting Component Design
```javascript
// ❌ Bad: Complex CSS to hide UI elements
.editor .toolbar { display: none !important; }
.editor .tabs { visibility: hidden !important; }
// ✅ Good: Use simpler component
<textarea value={content} onChange={e => setContent(e.target.value)} />
```
### 3. Hardcoded Config
```javascript
// ❌ Bad
target: 'http://127.0.0.1:8765'
// ✅ Good
const port = process.env.VITE_BACKEND_PORT || '8765';
target: `http://127.0.0.1:${port}`
```
### 4. CORS Issues
```python
# ✅ FastAPI CORS setup
from fastapi.middleware.cors import CORSMiddleware
app.add_middleware(
CORSMiddleware,
allow_origins=["http://localhost:5173"],
allow_methods=["*"],
allow_headers=["*"],
)
```
## Code Patterns
### Button States
```css
.btn { background: #007bff; transition: 0.2s; }
.btn:hover { background: #0056b3; }
.btn.active { background: #28a745; box-shadow: 0 2px 4px rgba(0,0,0,0.2); }
```
### Status Feedback
```javascript
const save = async () => {
try {
await saveToBackend();
setStatus('✓ Saved');
setTimeout(() => setStatus(''), 2000);
} catch (error) {
setStatus('❌ Error');
}
};
```
### Help Modal
```jsx
{helpOpen && (
<div className="modal" onClick={() => setHelpOpen(false)}>
<div className="content" onClick={e => e.stopPropagation()}>
<h3>⌨️ Shortcuts</h3>
<kbd>⌘ S</kbd> Save
<kbd>⌘ /</kbd> Help
</div>
</div>
)}
```
## Launcher Script
Create a simple script to start both servers:
```python
#!/usr/bin/env python3
import subprocess, webbrowser, time
# Start backend
backend = subprocess.Popen(
["uvicorn", "server:app", "--port", "8000"],
cwd="./backend"
)
# Start frontend
frontend = subprocess.Popen(
["npm", "run", "dev"],
cwd="./frontend"
)
time.sleep(2)
webbrowser.open("http://localhost:5173")
try:
backend.wait()
except KeyboardInterrupt:
backend.terminate()
frontend.terminate()
```
Make executable: `chmod +x launcher`
## Quick Reference
### Testing Checklist
```bash
# Automated
WEBTEST # Use testing-webapps skill
# Manual
- [ ] All buttons work
- [ ] Keyboard shortcuts (⌘S, ⌘/)
- [ ] Data persists
- [ ] No console errors
```
### When to Add a Feature
1. Solves real problem? ✓
2. Can be done simply? ✓
3. Fits core purpose? ✓
If any = no → defer it
### When to Refactor
- Code duplicated 3+ times
- Fighting component design
- Adding features getting harder
### View Modes Pattern
```jsx
const [viewMode, setViewMode] = useState('edit');
const [content, setContent] = useState('');
{viewMode === 'edit' && <Editor value={content} onChange={setContent} />}
{viewMode === 'diff' && <DiffView content={content} previous={prev} />}
{viewMode === 'preview' && <Preview content={content} />}
```
### Debugging
1. Console errors (browser + terminal)
2. Network tab (API responses)
3. React DevTools (state flow)
4. Use right component for the job?
### Success Criteria
- ✅ Core features work end-to-end
- ✅ Keyboard shortcuts (⌘S, ⌘/)
- ✅ No console errors
- ✅ Data persists
- ✅ Clean UI, no glitches
## Real Example: mdedit (3 hours total)
**Stack**: React + Vite + FastAPI + SQLite
**Features**: 4 view modes, version history, visual diff, keyboard shortcuts
**Key Decisions** (38 min research):
- FastAPI > Flask (type hints, async)
- SQLite > Postgres (zero config)
- Toast UI Editor for rich editing, but **textarea for diff mode** (fighting component = wrong tool)
- react-diff-viewer (GitHub-style, simple)
- marked for preview (lightweight)
**Lesson**: Don't fight components with CSS. Use simpler alternatives when needed.
---
## Key Reminders
**Design → Code → Test**
- Mock UI + interactions first
- Use defaults (React + RESTful)
- WEBTEST when done
**Red Flags:**
- Complex CSS hiding → wrong component
- Multiple states for same data → refactor
- Fighting a library → use different one
- > 30 min on one bug → rethink approach
**Best Prototypes Are:**
1. Fast (1-4 hours)
2. Simple (easy to change)
3. Polished (shortcuts + help)
4. Tested (no errors)

name: Reflecting on Learnings
description: Analyzes conversations to identify learnings, patterns, and techniques for capture in skills/snippets. Proposes updates or new skills, shows preview before changes. Use when user says "reflect", "what did we learn", or after complex tasks.
---
# REFLECT: Capture Learnings from Conversations
## Triggers
- User says "REFLECT" or "what did we learn?"
- End of complex task with new techniques
- After solving tricky problems with insights
- After using multiple skills in a session
## Core Principle
**Learn from doing.** Capture discoveries (techniques, approaches, patterns) into skills/snippets for future sessions.
## Workflow
### 1. Track Skills Used
Before analyzing, document all skills invoked during the session:
- Which skills were executed (e.g., "using-github-cli", "building-artifacts")
- When they were invoked (early, middle, late in session)
- How effective they were for the task
- Any patterns in skill usage
- Skills that worked well together vs. conflicts
Create or update eval file in `evals/` with this metadata.
### 2. Analyze Conversation
Identify:
- Tasks completed, problems solved, techniques used
- New approaches that worked, mistakes/lessons learned
- Patterns, effective tool combinations
- Knowledge gaps filled, misunderstandings corrected
- How invoked skills contributed to the solutions
### 2.5. Analyze Quibbler Interactions
Consider what rules could improve Quibbler's behavior:
- What patterns did you notice that Quibbler missed or could have caught earlier?
- Are there project-specific checks Quibbler should enforce (e.g., "always run X test before claiming completion")?
- What guidance would help Quibbler make better decisions about code quality in this project?
- Are there false positives where Quibbler flagged something unnecessarily?
**Decision**: Plan rules for `.quibbler/rules.md` that guide Quibbler to be more effective and accurate.
### 3. Categorize Discoveries
For each discovery:
**Update existing?** → Which skill/snippet? Which section? Correction/addition/clarification?
**Create new?** → Distinct topic? Independent invocation? Fills gap?
**Skip?** → Too specific? Already covered? Adds noise?
### 4. Store Evaluation Data
Save findings to `~/.claude/plugins/marketplaces/warren-claude-code-plugin-marketplace/claude-context-orchestrator/evals/`:
**File format:** `evals/{date}_{session_name}_{context}.md`
Example: `evals/2025-10-22_main_database-optimization.md`
**Evaluation file structure:**
```json
{
"date": "YYYY-MM-DD",
"session_name": "[name]",
"context": "[brief_description]",
"reproducible_prompt": "[original user prompt]",
"skills_invoked": [
"skill-name-1",
"skill-name-2"
]
}
```
### 5. Present Report
```
# Reflection Report: [Topic]
## Summary
[What was accomplished and key learnings]
## Discoveries
### [Discovery Name]
**Learned:** [Description]
**Matters:** [Value]
**Action:** Update `skills/[name]/SKILL.md` [section] OR Create `skills/[new]/SKILL.md`
## Proposed Changes
**Updates:**
`skills/existing/SKILL.md`
```diff
+ Add section on [technique]
+ Include example: [from conversation]
! Correct misconception
```
**New:**
`skills/new-skill/SKILL.md` - [Purpose], [Triggers], [Content]
**Summary:** [N] updates, [N] new, [Impact]
---
**Proceed? (yes/no)**
```
### 6. Get Confirmation
**CRITICAL:** No changes without explicit approval. Ask: "Review above. Proceed?"
### 7. Apply Changes (After Approval)
**Update existing:**
- Read file → Edit tool → Preserve structure → Add to appropriate sections
**Create new:**
- Use templates → YAML frontmatter → Clear description/triggers → Add examples
**Verify:**
- Confirm changes → Show summary → Provide paths
### 8. Report Completion
```
✅ Reflection complete!
Eval stored: evals/2025-10-22_main_database-optimization.md
Updated: skills/skill-1/SKILL.md (added X)
Created: skills/new-skill/SKILL.md
Skills tracked: [skill-1, skill-2, skill-3]
Learnings captured for future sessions.
```
## Analysis Strategies
**Look for:**
- Explicit learnings ("I discovered...", "key insight was...")
- Problem → Solution patterns (reusable workflows)
- Comparisons ("X didn't work, Y did")
- User corrections (misunderstandings to document)
- Repeated patterns (done multiple times = pattern)
- Tool/technique combinations
**Identify:**
- Before/After states, decision points
- Debugging journeys, integration patterns
- Error corrections → insights
**Prioritize (✅) vs Skip (❌):**
- ✅ High reusability, fills gaps, corrects misconceptions, simplifies complexity, from real problem-solving
- ❌ Edge cases, already documented, obvious, adds noise
## Best Practices
**Analyzing:** Be selective. Focus on "aha moments" not procedures. Prioritize future value. Patterns > single instances.
**Proposing:** Be specific (exact files/sections). Show value. Use examples. Clear preview.
**Updating:** Minimal edits. Preserve structure. Add, don't replace (unless correcting). Match existing style.
## File Locations
**Skills directory:**
```
/Users/wz/.claude/plugins/marketplaces/warren-claude-code-plugin-marketplace/claude-context-orchestrator/skills/{skill-name}/SKILL.md
```
**Snippets directory:**

}
```
# Reflection Report: Wikimedia Commons Images
## Summary
Learned proper workflow: WebSearch → WebFetch → verify → embed. Key: don't guess URL structures.
Skills combination (fetching + building) was highly effective.
## Discoveries
### Proper Workflow
**Learned:** WebSearch for file page → WebFetch for URL → curl verify → use in HTML
**Matters:** Prevents broken links, ensures attribution
**Action:** Update `skills/building-artifacts/SKILL.md` "External Resources" section
### Common Mistake
**Learned:** Wikimedia uses hash directories (/commons/7/72/Image.jpg) - can't guess
**Matters:** Prevents 404 errors
**Action:** Create `snippets/workflows/fetching-images/SNIPPET.md`
## Proposed Changes
**Update:** `skills/building-artifacts/SKILL.md`
+ Add "Embedding Images" section with 4-step workflow
! Note pitfall: Don't guess URL structures
**New:** `snippets/workflows/fetching-images/SNIPPET.md`
Purpose: Image embedding reference
Triggers: "embed image", "wikimedia commons"
Content: WebSearch patterns, WebFetch prompts, verification, attribution
**Summary:** 1 update, 1 new. Impact: Prevents common embedding mistakes.
---
**Proceed? (yes/no)**
User: "yes"
✅ Reflection complete!
Eval stored: evals/2025-10-22_main_image-embedding.md
Updated: skills/building-artifacts/SKILL.md (image embedding)
Created: snippets/workflows/fetching-images/SNIPPET.md
```
## Decision Guide
**Add when:**
- ✅ Concrete workflows from practice, corrections, proven patterns, actual examples, common pitfalls
**Skip when:**
- ❌ Theoretical/untested, edge cases, already covered, generic advice, obscures content
**Update existing:** Fits scope, fills gap, corrects content, adds examples
**Create new skill:** Distinct topic, independent invocation, clear gap
**Create snippet:** Context-injected, quick reference, clear triggers, broadly applicable
## Meta
REFLECT improves over time: Track patterns, learn from feedback, adapt analysis, refine proposals.
**Skill Tracking for Continuous Improvement:**
- Evaluation files in `evals/` create a history of skill effectiveness
- Review evals periodically to identify:
- Which skills are most valuable in different contexts
- Skill combinations that work well together
- Skills that might need enhancement
- Gaps in available skills
- Use this data to improve existing skills and identify new ones to create
Works with: managing-skills, creating-skills, updating-skills, EXPLAIN
**Goal:** Capture insights for better future work. Focus on: save time, avoid mistakes, reusable patterns, simplify complexity. Build data on skill effectiveness over time.

name: Searching Deeply
description: Iterative parallel search strategy using WebSearch and Exa. Launch multiple searches simultaneously, learn from failures, and keep iterating until finding answers. Use for research, code examples, documentation, and technical information gathering.
---
# Searching Deeply
## Core Strategy
**Search in parallel. Learn from failures. Keep iterating.**
Never give up after one search round. Launch new searches based on what worked and what didn't.
## Available Tools
- **WebSearch** - General info, news, tutorials, overviews (free, fast)
- **mcp__exa__get_code_context_exa** - Code examples, implementations ($0.01/query)
- **mcp__exa__web_search_exa** - Academic papers, technical docs ($0.01/query)
## Related Skills & Snippets
- **google-scholar** skill - For academic paper research with citation tracking
- **DOWNLOAD** snippet - For downloading PDFs from Anna's Archive
- **document-skills:pdf** - For extracting text from downloaded papers
## Iterative Workflow
### Round 1: Launch Parallel Searches
Start with 3-5 searches from different angles:
**General topics:**
- WebSearch with variations of query
- Different phrasings, synonyms, related terms
- Add context: year "2024 2025", tech stack, keywords
**Code/implementation:**
- WebSearch for overview/tutorial
- mcp__exa__get_code_context_exa for real examples
**Academic/research:**
- WebSearch for overview
- mcp__exa__web_search_exa for papers
- Use google-scholar skill for deeper research
### Round 2: Analyze & Iterate
**What did you learn?**
- New terminology discovered?
- Specific authors/sources mentioned?
- Related topics to explore?
**What's missing?**
- Gaps in understanding
- Unanswered questions
- Need more examples/evidence
**Launch next round:**
- Reformulate queries with new terms
- Search for specific gaps
- Try broader or narrower scope
- 3-5 new parallel searches
### Round 3+: Keep Going
**Don't stop until:**
- Question fully answered
- Multiple sources confirm findings
- Examples found and verified
- All gaps identified and filled
**If stuck:**
- Try different keywords/synonyms
- Split complex query into parts
- Search related topics first
- Switch tools (WebSearch ↔ Exa)
- Check alternative sources
## Query Optimization
**Make queries specific:**
- ❌ "authentication"
- ✅ "JWT authentication Express.js tutorial 2025"
**Add context:**
- Technology: "Node.js", "Python", "React"
- Timeframe: "2024 2025" for recent
- Type: "tutorial", "example", "production", "best practices"
**Use domain filtering:**
- Academic: `allowed_domains: ["*.edu", "arxiv.org"]`
- Developer: `allowed_domains: ["github.com", "dev.to"]`
## Persistence Rules
**Never give up after one failed search.**
If results are poor:
1. Try different keywords
2. Broaden or narrow scope
3. Split into smaller questions
4. Switch tools
5. Search related topics first
**Keep iterating until satisfied.**
## Common Research Patterns
### Quick Answer
Single focused WebSearch with specific query
### General Research
- 3-5 parallel WebSearch with different angles
- Iterate based on results
### Code Research
- WebSearch for overview
- mcp__exa__get_code_context_exa for examples
- Iterate for edge cases, error handling
### Academic Research
- WebSearch for overview
- mcp__exa__web_search_exa for papers
- Use **google-scholar** skill for citations
- Use **DOWNLOAD** snippet for PDFs
- Use **document-skills:pdf** to extract content
## Example: Iterative Search
**Round 1:**
```
WebSearch: "Python async programming"
→ Learned: asyncio is the main library
```
**Round 2:**
```
WebSearch: "Python asyncio tutorial 2025"
WebSearch: "asyncio vs threading when to use"
mcp__exa__get_code_context_exa: "Python asyncio examples"
→ Learned: Good basics, but need error handling
```
**Round 3:**
```
WebSearch: "asyncio error handling best practices"
WebSearch: "asyncio common mistakes"
mcp__exa__get_code_context_exa: "asyncio exception handling"
→ Complete understanding achieved
```
## Validation
Cross-reference findings:
- Check multiple sources
- Verify recent dates (2024-2025)
- Look for authoritative sources
- Test code examples
- Confirm consistency
## Quick Reference
**Default:** 3-5 parallel WebSearch with different angles
**For code:** Add mcp__exa__get_code_context_exa
**For papers:** Add mcp__exa__web_search_exa or use google-scholar skill
**For PDFs:** Use DOWNLOAD snippet
**When stuck:** Reformulate, try new terms, iterate
**Remember:** Keep going until you find complete answers

name: Testing Webapps
description: Toolkit for interacting with and testing local web applications using Playwright. Supports verifying frontend functionality, debugging UI behavior, capturing browser screenshots, and viewing browser logs.
license: Complete terms in LICENSE.txt
---
# Web Application Testing
Write native Python Playwright scripts to test local webapps.
**Helper**: `scripts/with_server.py` manages server lifecycle. Run with `--help` first.
## Approach
**Static HTML**: Read file → identify selectors → write script
**Dynamic webapp**:
- Server not running: Use `with_server.py`
- Server running: Navigate → wait networkidle → inspect → act
## Server Management
```bash
# Single server
python scripts/with_server.py --server "npm run dev" --port 5173 -- python automation.py
# Multiple servers
python scripts/with_server.py \
--server "cd backend && python server.py" --port 3000 \
--server "cd frontend && npm run dev" --port 5173 \
-- python automation.py
```
## Script Patterns
**Automation**:
```python
from playwright.sync_api import sync_playwright
with sync_playwright() as p:
browser = p.chromium.launch(headless=True)
page = browser.new_page()
page.goto('http://localhost:5173')
page.wait_for_load_state('networkidle') # CRITICAL for dynamic apps
# automation logic here
browser.close()
```
**Reconnaissance**:
```python
page.screenshot(path='/tmp/inspect.png', full_page=True)
page.content() # Get HTML
page.locator('button').all() # Find elements
```
## Headless Mode + Trace Viewer (Recommended for macOS)
**Problem**: Headed mode steals window focus on macOS, disrupting workflow.
**Solution**: Run headless with trace recording:
```python
import os
headless = os.getenv('HEADED') != '1' # Default headless, override with HEADED=1
browser = p.chromium.launch(headless=headless)
context = browser.new_context()
context.tracing.start(screenshots=True, snapshots=True, sources=True)
page = context.new_page()
# ... test code ...
# Save trace on completion
context.tracing.stop(path="/tmp/trace_testname_SUCCESS.zip")
```
**Debug traces**:
```bash
playwright show-trace /tmp/trace_testname_SUCCESS.zip
```
**Why better than headed**: Step through at your own pace, inspect DOM at any point, see network requests, no window disruption.
## Selector Best Practices
**Emoji-safe text matching**:
```python
# ❌ Fails with emoji
page.locator('text="Mission Control"')
# ✅ Works with "Mission Control 🚀"
page.locator('text=/Mission Control/')
```
**Button-specific selectors**:
```python
# ❌ Too generic, matches any text
page.locator('text="Create World"')
# ✅ Specific to buttons
page.locator('button:has-text("Create World")')
```
**Form field specificity**:
```python
# ❌ Fragile, matches wrong element
page.locator('textarea').first
# ✅ Specific placeholder
page.locator('textarea[placeholder*="description"]')
page.locator('input[type="text"]').nth(2) # If index matters
```
**Wait for both visible AND enabled**:
```python
button = page.locator('button:has-text("Submit")')
expect(button).to_be_visible(timeout=5000)
expect(button).to_be_enabled(timeout=5000) # Critical for form buttons!
button.click()
```
## Form Testing Pattern
**Rule**: Fill → Wait for enabled → Click
**Wrong order (causes timeouts)**:
```python
# ❌ Button is disabled, causes "element not enabled" timeout
button.click()
textarea.fill("content")
```
**Correct order**:
```python
# ✅ Button becomes enabled after fill
textarea = page.locator('textarea[placeholder="description"]')
expect(textarea).to_be_visible(timeout=5000)
textarea.fill("content")
button = page.locator('button:has-text("Submit")')
expect(button).to_be_enabled(timeout=5000) # Now enabled
button.click()
```
**Why**: Most forms disable submit buttons until validation passes. Always fill first.
## Test Setup: Database State
**Pattern for clean test runs**:
```bash
# Reset database before tests
rm -f backend/database.db
cd backend && python -c "from src.database import init_db; import asyncio; asyncio.run(init_db())"
```
**In test runner**:
```python
from pathlib import Path
import subprocess
def setup_clean_database():
"""Reset database to clean state."""
db_path = Path("backend/database.db")
if db_path.exists():
db_path.unlink()
subprocess.run([
"python", "-c",
"from src.database import init_db; import asyncio; asyncio.run(init_db())"
], cwd="backend")
```
**Why**: Prevents UUID conflicts, UNIQUE constraint violations, and flaky tests from stale data.
## Debugging Triad: Screenshot + Trace + Console
**Always capture all three**:
```python
# Setup
context.tracing.start(screenshots=True, snapshots=True, sources=True)
logs = []
page.on("console", lambda msg: logs.append(f"[{msg.type}] {msg.text}"))
# During test - take screenshots at key steps
page.screenshot(path='/tmp/test_step1.png')
# On failure
context.tracing.stop(path="/tmp/trace_FAILED.zip")
print(f"Console logs (last 20):")
for log in logs[-20:]:
print(f" {log}")
```
**Why each matters**:
- **Screenshots**: Visual state at failure point
- **Trace**: Full interaction timeline, DOM snapshots, network activity
- **Console**: React errors, API failures, JavaScript warnings
**Debugging workflow**:
1. Check console logs for errors first (fastest)
2. View screenshot to understand visual state
3. Open trace with `playwright show-trace` to step through and inspect DOM
## Troubleshooting
### "Fix doesn't work" - Tests still fail after code change
**Symptom**: Fixed a bug but tests still fail with same error.
**Causes & Solutions**:
1. **Frontend hot reload hasn't applied changes**
- Verify file: `grep "new code" file.jsx`
- Check dev server console for reload confirmation
- Hard restart: Kill dev server, `npm run dev`
2. **Browser cache**
- Use `page.goto(..., wait_until='networkidle')`
- Or clear: `context.clear_cookies()`
### Generic selectors match wrong elements
**Symptom**: `textarea.first` or `button.last` fails unexpectedly or matches wrong element.
**Cause**: DOM structure changed or multiple matching elements exist.
**Solution**: Use attribute selectors:
```python
# ❌ Fragile - depends on DOM order
page.locator('textarea').first
# ✅ Robust - matches specific element
page.locator('textarea[placeholder="World description"]')
page.locator('button:has-text("Create")').first # If multiple, be specific
```
### "Element not enabled" timeouts
**Symptom**: `page.click()` times out with "element is not enabled".
**Cause**: Trying to click button before form validation passes.
**Solution**: Fill form first, then wait for enabled:
```python
# Fill all required fields first
input1.fill("value1")
input2.fill("value2")
# Then wait for button to enable
button = page.locator('button:has-text("Submit")')
expect(button).to_be_enabled(timeout=5000)
button.click()
```
## Critical Rules
- **Always** `page.wait_for_load_state('networkidle')` before DOM inspection
- **Default to headless** with trace recording for debugging without window disruption
- **Fill forms before clicking** submit buttons (they're usually disabled)
- **Use specific selectors** with attributes, not generic `.first`/`.last`
- **Capture triad**: screenshots + trace + console logs for debugging
- Close browser when done
- See `examples/` for more patterns

## Install
```bash
npm install -g @openai/codex
codex --version
```
## Config
`~/.codex/config.toml`:
```toml
model = "gpt-5-codex"
model_reasoning_effort = "high"
approval_policy = "never"
sandbox_mode = "workspace-write"
web_search = true
```
## Commands
**Interactive:** Real-time development
```bash
codex "Create a Python REST API"
```
**Exec:** Automation
```bash
codex exec "Task" --full-auto
```
---
## Bash Scripting
### Basic
```bash
#!/bin/bash
set -euo pipefail
cd /tmp/project
git init && git config user.email "bot@example.com" && git config user.name "Bot"
codex exec "Your task" --full-auto
```
### With Clean Output
```bash
codex exec "Your task" --full-auto --output-last-message /tmp/result.txt
cat /tmp/result.txt
```
### Idempotent
```bash
#!/bin/bash
set -euo pipefail
log() { printf '[%s] %s\n' "$(date +%H:%M:%S)" "$*"; }
ensure_tool() { command -v "$1" >/dev/null || { log "install $1"; exit 1; }; }
case "${1:-help}" in
bootstrap)
ensure_tool jq
[[ -f .ready ]] || { ./setup.sh && touch .ready; }
;;
ci)
for step in lint test build; do
log "running $step"
./scripts/$step.sh || exit 1
done
;;
watch)
ensure_tool entr
find src -type f | entr -r bash -lc './scripts/test.sh'
;;
*)
printf 'usage: %s {bootstrap|ci|watch}\n' "$0" >&2; exit 64
;;
esac
```
### Git Checkpoint
```bash
#!/bin/bash
set -euo pipefail
git add . && git commit -m "Before Codex" || true
codex exec "Run tests and fix failures" --full-auto || {
git reset --hard HEAD~1
exit 1
}
git add . && git commit -m "Codex: Fixed" || true
```
### Batch
```bash
#!/bin/bash
for project in project1 project2 project3; do
(
cd "$project"
git init && git config user.email "bot@example.com" && git config user.name "Bot" || true
if codex exec "Update dependencies" --full-auto; then
git add . && git commit -m "Updated" --allow-empty || true
echo "✓ $project"
else
git reset --hard HEAD~1
echo "✗ $project"
fi
)
done
```
---
## Web Search
Enable with `-c web_search=true`.
### Research with JSON
```bash
#!/bin/bash
cd /tmp/research
git init && git config user.email "bot@example.com"
task="Find top 3 bash patterns. Return ONLY valid JSON with: pattern, description, code_example."
codex exec "$task" \
-c web_search=true \
--full-auto \
--output-last-message /tmp/result.json
cat /tmp/result.json | jq .
```
### View Searches
```bash
codex exec "Research bash best practices" \
-c web_search=true \
--full-auto \
--json 2>/dev/null | \
jq -r 'select(.type=="web_search") | .item.query'
```
### View Reasoning
```bash
codex exec "Research X" \
-c web_search=true \
--full-auto \
--json 2>/dev/null | \
jq -r 'select(.type=="reasoning") | .item.text'
```
---
## Output Control
**`--output-last-message FILE`** - Writes final answer to FILE only.
```bash
codex exec "Task" --full-auto --output-last-message /tmp/answer.txt
cat /tmp/answer.txt
```
Result:
- FILE: Clean plaintext answer
- STDOUT: 5 lines metadata
- STDERR: Empty
**`--json`** - JSONL events: thread.started, turn.started, reasoning, web_search, agent_message, turn.completed.
```bash
codex exec "Task" --full-auto --json 2>/dev/null | jq '.type' | sort | uniq -c
```
**Suppress console:** Redirect to /dev/null
```bash
codex exec "Task" --full-auto --output-last-message /tmp/answer.txt >/dev/null 2>&1
cat /tmp/answer.txt
```
**Save audit log + clean output:**
```bash
codex exec "Task" --full-auto \
--output-last-message /tmp/answer.txt \
--json >/tmp/audit.jsonl 2>&1
cat /tmp/answer.txt
```
---
## Python
### Simple
```python
import subprocess
result = subprocess.run(
['codex', 'exec', 'Create test module', '--full-auto'],
cwd='/tmp/project',
capture_output=True,
text=True
)
print(result.stdout)
```
### Wrapper
```python
from dataclasses import dataclass
from typing import Optional
import subprocess
import os
@dataclass
class CodexResult:
returncode: int
stdout: str
stderr: str
task: str
@property
def success(self) -> bool:
return self.returncode == 0
class CodexCLI:
def __init__(self, model="gpt-5-codex", web_search=False):
self.model = model
self.web_search = web_search
def execute(self, task: str, cwd: Optional[str] = None) -> CodexResult:
output_file = f"/tmp/codex-{os.urandom(4).hex()}.txt"
cmd = [
'codex', 'exec', task,
'--full-auto',
'-m', self.model,
'--output-last-message', output_file
]
if self.web_search:
cmd.extend(['-c', 'web_search=true'])
result = subprocess.run(
cmd,
cwd=cwd or os.getcwd(),
capture_output=True,
text=True
)
try:
with open(output_file) as f:
output = f.read()
os.unlink(output_file)
except:
output = result.stdout
return CodexResult(
returncode=result.returncode,
stdout=output,
stderr=result.stderr,
task=task
)
# Usage
codex = CodexCLI(web_search=True)
result = codex.execute("Research X")
print(result.stdout)
```

## Flags
| Flag | Purpose |
|------|---------|
| `--full-auto` | Auto-approve, workspace-write sandbox |
| `-c web_search=true` | Enable web search |
| `--output-last-message FILE` | Write final answer to FILE |
| `--json` | Stream JSONL events |
| `-m, --model` | gpt-5 (fast), gpt-5-codex (code), o3 (powerful) |
| `-C, --cd` | Working directory |
---
## Patterns
**Research + JSON**
```bash
codex exec "Find X. Return JSON with: pattern, description, code." \
-c web_search=true --full-auto --output-last-message /tmp/result.json
```
**Batch docs**
```bash
for module in auth utils data; do
codex exec "Generate API docs for $module.py" \
--full-auto --output-last-message "/tmp/${module}_docs.md"
done
```
**Research → Generate → Commit**
```bash
codex exec "Research Python testing best practices 2025" \
-c web_search=true --full-auto --output-last-message /tmp/research.txt
codex exec "Using this research, generate test suite for module.py" --full-auto
git add . && git commit -m "Generated tests from latest best practices"
```
---
## Performance
| Task | Time | Success |
|------|------|---------|
| Simple | 30-60s | 99%+ |
| Web search | 60-120s | 95%+ |
| Complex | 120+s | 90%+ |
**Models:**
- `gpt-5`: Fast, cheap
- `gpt-5-codex`: Default, code-optimized
- `o3`: Powerful, slow
---
## Security
**Safe:**
- `workspace-write` sandbox (default)
- Git checkpoints before Codex
- Validate generated code
**Avoid:**
- `danger-full-access` without external sandboxing
- Running without git checkpoints
- Web search on untrusted domains
---
## Troubleshooting
| Problem | Solution |
|---------|----------|
| `codex not found` | `npm install -g @openai/codex` |
| Not in trusted directory | `git init` in working directory |
| Web search returns nothing | Rephrase as task ("Find X"), not question |
| Too much output | Use `--output-last-message FILE` |
| Can't parse output | Use `--json` with `jq` |
| Auth failed | `codex login` or set `OPENAI_API_KEY` |
---
## Quick Reference
```bash
# Basic
codex exec "Task" --full-auto
# Web search
codex exec "Research X" -c web_search=true --full-auto
# Clean output
codex exec "Task" --full-auto --output-last-message /tmp/out.txt
# View searches
codex exec "Task" -c web_search=true --full-auto --json 2>/dev/null | \
jq -r 'select(.type=="web_search") | .item.query'
# Token usage
codex exec "Task" --full-auto --json 2>/dev/null | \
jq 'select(.type=="turn.completed") | .usage'
# Different model
codex exec "Task" -m o3 --full-auto
# Specific directory
codex exec "Task" -C /path/to/project --full-auto
```

name: uv-debug
description: Troubleshooting and debugging problems with uv (Python package manager). Use when encountering uv installation issues, stale build cache, package not updating, or discrepancies between uv run and global installs.
---
# UV Debugging Skill
## Purpose
This skill provides systematic troubleshooting workflows for common `uv` (Python package manager) issues, with particular focus on build cache problems, installation discrepancies, and package update issues.
## When to Use This Skill
Use this skill when encountering:
- Code changes not appearing after `uv tool install`
- Discrepancy between `uv run <command>` and globally installed command
- New files/modules missing from installed package
- "Command not found" after installation
- Stale build cache issues
- Installation mode confusion (editable vs production)
## Core Concepts
### UV Installation Modes
**Production Install:**
```bash
uv tool install .
```
- Builds wheel package (cached snapshot)
- Fast to install, slow to update
- Requires reinstall after code changes
- Isolated from source directory
**Editable Install:**
```bash
uv tool install --editable .
```
- Creates symlinks to source directory
- Changes reflect immediately
- Best for active development
- Less isolated
**Local Environment:**
```bash
uv sync # Setup environment
uv run <command> # Execute from source
```
- No global install needed
- Always uses current source code
- Fastest iteration cycle
- Recommended for development
### Build Cache Location
**Global tool installs:**
```
~/.local/share/uv/tools/<package-name>/
```
**Build artifacts:**
```
build/ - Temporary build files
dist/ - Built wheels (.whl) and source distributions
*.egg-info/ - Package metadata and file manifest
```
## Troubleshooting Workflows
### Workflow 1: Code Changes Not Appearing
**Symptoms:**
- Ran `uv tool install .` or `make install`
- Code changes don't appear in installed command
- New files/modules missing
**Diagnostic Steps:**
1. **Verify the discrepancy:**
```bash
# Check which version is running
which <command>
# Test local version
uv run <command> --help
# Test global version
<command> --help
```
2. **Check for stale build artifacts:**
```bash
ls -la build/ dist/ *.egg-info 2>/dev/null
```
3. **Identify installation mode:**
```bash
# Check if editable install
ls ~/.local/share/uv/tools/<package>/ | grep -i editable
```
**Solutions (in order of preference):**
**Solution A: Clean and Reinstall (Recommended)**
```bash
# Remove stale artifacts
rm -rf build/ dist/ *.egg-info
# Force fresh build
uv tool install --force .
# Verify
<command> --help
```
**Solution B: Use Makefile Pattern**
```makefile
install: clean
uv tool install --force .
clean:
rm -rf build/ dist/ *.egg-info
find . -type d -name __pycache__ -exec rm -rf {} + 2>/dev/null || true
```
**Solution C: Switch to Local Environment**
```bash
# Setup once
uv sync
# Use for development
uv run <command>
```
**Solution D: Use Editable Mode**
```bash
uv tool install --editable .
```
### Workflow 2: New Module Not Found
**Symptoms:**
- Added new Python file (e.g., `mypackage/commands/new_cmd.py`)
- `ModuleNotFoundError` or command not recognized
- `uv run` works but global install doesn't
**Root Cause:**
Wheel package built before new file existed. Package metadata (`*.egg-info/RECORD`) doesn't list the new file.
**Solution:**
```bash
# 1. Clean build artifacts
rm -rf build/ dist/ *.egg-info
# 2. Reinstall with force
uv tool install --force .
# 3. Verify new module appears
<command> <new-subcommand> --help
```
**Prevention:**
Add to Makefile:
```makefile
install: clean
uv tool install --force .
```
### Workflow 3: Debugging Installation Location
**Symptoms:**
- Unsure which version is running
- Multiple installations conflict
- Changes not appearing despite reinstall
**Diagnostic Commands:**
```bash
# 1. Check which executable
which <command>
# 2. Check Python import location
python3 -c "import <package>; print(<package>.__file__)"
# 3. List all installations
find ~/.local/share/uv/tools -name "<package>*"
# 4. Check if editable install
cat ~/.local/share/uv/tools/<package>/*/site-packages/*.pth 2>/dev/null
```
**Interpretation:**
If `which <command>` shows:
- `~/.local/share/uv/tools/` → Global uv install
- `/usr/local/bin/` → System-wide install (pip)
- `<project>/.venv/bin/` → Virtual environment
If `.pth` file exists → Editable install (points to source)
### Workflow 4: Entry Point Not Updating
**Symptoms:**
- Changed command name or added new subcommand
- Entry point not updating in installed version
**Root Cause:**
Entry points defined in `pyproject.toml` are baked into wheel at build time.
**Solution:**
1. **Verify entry point definition:**
```bash
# Read pyproject.toml
grep -A 10 "\[project.scripts\]" pyproject.toml
```
2. **Clean and rebuild:**
```bash
rm -rf build/ dist/ *.egg-info
uv tool install --force .
```
3. **Verify entry points installed:**
```bash
ls ~/.local/share/uv/tools/<package>/*/bin/
```
### Workflow 5: Dependency Issues
**Symptoms:**
- Import errors for dependencies
- Version conflicts
- `ModuleNotFoundError` for installed packages
**Diagnostic:**
```bash
# Check installed dependencies
uv pip list
# Check project dependencies
grep -A 20 "dependencies" pyproject.toml
# Check dependency resolution
uv pip tree
```
**Solution:**
```bash
# Sync dependencies
uv sync --all-extras
# Or for global install
uv tool install --force --reinstall-package <package> .
```
## Decision Tree
```
Code changes not appearing?
├─ Does `uv run <cmd>` work?
│ ├─ Yes → Stale build cache
│ │ └─ Solution: rm -rf build/ dist/ *.egg-info && uv tool install --force .
│ └─ No → Code issue, not cache
│ └─ Debug the code itself
│
├─ New file/module missing?
│ └─ Solution: Clean build artifacts and reinstall
│
├─ Entry point not found?
│ └─ Check pyproject.toml [project.scripts], then clean and reinstall
│
└─ Dependency missing?
└─ Run uv sync or uv tool install --reinstall-package
```
## Best Practices
### Development Workflow
**Option 1: Local Environment (Recommended)**
```bash
# Setup once
uv sync
# Develop with instant updates
uv run <command>
uv run pytest
```
**Option 2: Editable Install**
```bash
# Install once
uv tool install --editable .
# Changes reflect immediately
<command> # Always uses latest source
```
**Option 3: Production Build with Makefile**
```bash
# Makefile ensures clean builds
make install
# Reinstall after each change
make install
```
### Testing Installation
Before distributing or deploying:
```bash
# 1. Clean environment
rm -rf build/ dist/ *.egg-info
# 2. Production build
uv tool install --force .
# 3. Test from clean shell
<command> --help
<command> <subcommand>
# 4. Verify all entry points
ls ~/.local/share/uv/tools/<package>/*/bin/
```
## Common Mistakes
### Mistake 1: Assuming `--force` Cleans Cache
**Wrong:**
```bash
uv tool install --force . # Doesn't clean build artifacts!
```
**Right:**
```bash
rm -rf build/ dist/ *.egg-info
uv tool install --force .
```
**Why:** `--force` reinstalls but may reuse cached wheel from `dist/`.
### Mistake 2: Editing Global Install Directly
**Wrong:**
```bash
# Editing files in ~/.local/share/uv/tools/<package>/
vim ~/.local/share/uv/tools/<package>/.../myfile.py
```
**Right:**
```bash
# Edit source, then reinstall
vim mypackage/myfile.py
make install
```
### Mistake 3: Mixing Installation Methods
**Problem:**
```bash
uv tool install . # Production install
# Later...
uv tool install --editable . # Now editable
# Changes behavior unpredictably
```
**Solution:**
Pick one method and stick with it, or uninstall first:
```bash
uv tool uninstall <package>
uv tool install --editable .
```
## Advanced Debugging
### Inspecting Wheel Contents
```bash
# Build wheel
uv build
# List contents
unzip -l dist/*.whl
# Extract and examine
unzip dist/*.whl -d /tmp/wheel-inspect
ls -la /tmp/wheel-inspect/<package>/
```
### Checking Package Metadata
```bash
# View installed package info
uv pip show <package>
# View RECORD file (manifest of installed files)
cat ~/.local/share/uv/tools/<package>/*/*.dist-info/RECORD
```
### Debugging Import Paths
```python
import sys
print("Python path:")
for p in sys.path:
print(f" {p}")
import <package>
print(f"\nPackage location: {<package>.__file__}")
```
## Reference: Build Process
Understanding what happens during `uv tool install .`:
1. **Read metadata** - Parse `pyproject.toml` for package info
2. **Collect files** - Find all Python files in package
3. **Build wheel** - Create `.whl` in `dist/`
4. **Write manifest** - Record all files in `*.egg-info/RECORD`
5. **Install wheel** - Copy to `~/.local/share/uv/tools/<package>/`
6. **Create entry points** - Generate executables in `bin/`
**Key insight:** Steps 3-4 create a snapshot. New files added after this won't be included until rebuild.
## Quick Reference
**Check what's running:**
```bash
which <command>
uv run <command> --version
<command> --version
```
**Clean build cache:**
```bash
rm -rf build/ dist/ *.egg-info
```
**Fresh install:**
```bash
uv tool install --force .
```
**Development mode:**
```bash
uv sync && uv run <command>
```
**Inspect installation:**
```bash
ls ~/.local/share/uv/tools/<package>/
uv pip show <package>
```

# Python Build Cache Deep Dive
## Overview
This document explains in detail how Python's packaging system caches builds, why this causes "code not updating" issues, and the technical mechanisms behind different installation modes.
## The Build Process
### Standard Build (Non-Editable)
When running `uv tool install .` or `pip install .`:
```
Source Code → setup.py/pyproject.toml → Build Backend → Wheel → Installation
```
**Step-by-step breakdown:**
1. **Parse metadata:**
- Read `pyproject.toml` or `setup.py`
- Extract: name, version, dependencies, entry points
- Determine which files to include
2. **Collect source files:**
- Find all `.py` files in package
- Apply MANIFEST.in rules (if exists)
- Apply `pyproject.toml` includes/excludes
3. **Build wheel (.whl):**
- Compile C extensions (if any)
- Copy Python files
- Generate metadata files
- Create ZIP archive named `<package>-<version>-py3-none-any.whl`
- Store in `dist/` directory
4. **Generate metadata:**
- Create `<package>.egg-info/` directory
- Write `SOURCES.txt` (list of source files used)
- Write `RECORD` (list of files to install)
- Write `entry_points.txt` (console scripts)
- Write `requires.txt` (dependencies)
5. **Install wheel:**
- Extract wheel to installation directory
- Create entry point executables in `bin/`
- Update Python's package registry
**Key files created:**
```
build/
├── lib/
│ └── mypackage/
│ └── (compiled files)
└── bdist.*/
└── (platform-specific builds)
dist/
└── mypackage-1.0.0-py3-none-any.whl ← The cached snapshot
mypackage.egg-info/
├── SOURCES.txt ← Source files at build time
├── RECORD ← Files to install
├── entry_points.txt ← Console scripts
└── requires.txt ← Dependencies
```
### Why It's a Snapshot
**The wheel is a frozen moment in time:**
```python
# At build time (t=0):
mypackage/
├── __init__.py ← Included in wheel
├── cli.py ← Included in wheel
└── commands/
├── send.py ← Included in wheel
└── read.py ← Included in wheel
# After adding new file (t=1):
mypackage/
├── __init__.py
├── cli.py
└── commands/
├── send.py
├── read.py
└── workflows.py ← NOT in wheel! Built at t=0
```
**The wheel still contains only files from t=0:**
```bash
$ unzip -l dist/mypackage-1.0.0-py3-none-any.whl
mypackage/__init__.py
mypackage/cli.py
mypackage/commands/send.py
mypackage/commands/read.py
# workflows.py is MISSING
```
**Even `--force` reinstall uses this stale wheel:**
```bash
uv tool install --force .
# Still installs the old wheel from dist/!
```
## Installation Locations
### UV Tool Install
```
~/.local/share/uv/tools/<package>/
├── bin/
│ └── <command> ← Executable entry point
├── lib/
│ └── python3.x/
│ └── site-packages/
│ ├── <package>/ ← Package code
│ └── <package>-<version>.dist-info/
│ ├── RECORD
│ ├── entry_points.txt
│ └── METADATA
```
### Editable Install
**Instead of copying files, creates pointer:**
```
~/.local/share/uv/tools/<package>/
├── bin/
│ └── <command>
└── lib/
└── python3.x/
└── site-packages/
├── __editables__/
│ └── <package>.pth ← Points to source directory
└── <package>-<version>.dist-info/
```
**The `.pth` file contains:**
```
/absolute/path/to/source/directory
```
**Python's import system:**
1. Reads `.pth` file
2. Adds path to `sys.path`
3. Imports directly from source directory
4. New files appear immediately (no reinstall)
### Local Environment (uv run)
**No global installation at all:**
```
project/
├── .venv/
│ ├── bin/
│ │ └── python ← Local Python interpreter
│ └── lib/
│ └── python3.x/
│ └── site-packages/ ← Dependencies only
├── mypackage/ ← Source code (NOT installed)
└── pyproject.toml
```
**How `uv run` works:**
```bash
uv run mycommand
```
Internally executes:
```bash
PYTHONPATH=/path/to/project:$PYTHONPATH \
.venv/bin/python -m mypackage.cli
```
**Import resolution:**
1. Check `PYTHONPATH` first (finds `mypackage/` in project root)
2. Import directly from source
3. No build, no cache, always latest
## Why --force Doesn't Help
**Common misconception:**
```bash
uv tool install --force . # "Force should rebuild, right?"
```
**What `--force` actually does:**
- Uninstalls existing package
- Reinstalls from available sources
- **Does NOT** delete `build/` or `dist/`
**The problem:**
```bash
# 1. First install (builds wheel)
uv tool install .
# Creates: dist/mypackage-1.0.0-py3-none-any.whl
# 2. Add new file
touch mypackage/commands/workflows.py
# 3. Force reinstall
uv tool install --force .
# Finds existing wheel in dist/
# Reinstalls OLD wheel (still no workflows.py!)
```
**Why it finds the old wheel:**
UV's build process:
1. Check if wheel exists in `dist/` matching current version
2. If yes, use that wheel (fast!)
3. If no, build new wheel
**The version in `pyproject.toml` hasn't changed**, so UV reuses the cached wheel.
## How to Force Fresh Build
**Option 1: Clean first**
```bash
rm -rf build/ dist/ *.egg-info
uv tool install --force .
```
**Option 2: Bump version**
```toml
[project]
version = "1.0.1" # Changed from 1.0.0
```
```bash
uv tool install --force .
# No matching wheel in dist/, builds fresh
```
**Option 3: Build explicitly**
```bash
uv build --force
uv tool install --force .
```
## Metadata Files Deep Dive
### RECORD File
Lists every file installed, with checksums:
```
mypackage/__init__.py,sha256=abc123...,1234
mypackage/cli.py,sha256=def456...,5678
mypackage/commands/send.py,sha256=ghi789...,9012
mypackage/commands/read.py,sha256=jkl012...,3456
```
**New files aren't in RECORD = won't be installed**
### entry_points.txt
Defines console scripts:
```
[console_scripts]
gmail = mypackage.cli:main
```
**This is read at install time to create executables in `bin/`**
Changes to entry points require rebuild.
### SOURCES.txt
Lists source files used during build:
```
mypackage/__init__.py
mypackage/cli.py
mypackage/commands/send.py
mypackage/commands/read.py
setup.py
pyproject.toml
```
**Diagnostic use:** If a file is missing here, it wasn't included in the build.
## Debugging Cache Issues
### Check if wheel is stale
```bash
# 1. List files in wheel
unzip -l dist/*.whl | grep -i workflows
# If empty, file not in wheel
# 2. Check SOURCES.txt
cat *.egg-info/SOURCES.txt | grep workflows
# If empty, file wasn't included in build
# 3. Check build timestamp
ls -la dist/*.whl
# If older than source files, rebuild needed
```
### Compare local vs installed
```bash
# Source files
find mypackage -name "*.py" | sort
# Installed files
find ~/.local/share/uv/tools/mypackage -name "*.py" | sort
# Diff them
diff <(find mypackage -name "*.py" | sort) \
<(find ~/.local/share/uv/tools/mypackage -name "*.py" | sed 's|.*mypackage|mypackage|' | sort)
```
### Verify import source
```python
import mypackage
print(mypackage.__file__)
# Should point to installed location, not source
```
## Performance Trade-offs
### Why Caching Exists
**Without caching (rebuild every time):**
- Slow: Parsing, file collection, wheel building (seconds to minutes)
- Wasteful: Rebuilding unchanged code
- Inconsistent: Different builds might produce different results
**With caching (reuse wheel):**
- Fast: Just extract and copy (milliseconds)
- Efficient: Build once, install many
- Reproducible: Same wheel = same result
**The trade-off:**
- Development: Need to rebuild after changes (overhead)
- Production: Install is fast and predictable (benefit)
## Best Practices by Use Case
### Active Development
```bash
# Option 1: No install (recommended)
uv sync
uv run mycommand
# Option 2: Editable install
uv tool install --editable .
# Option 3: Makefile automation
make install # (with clean dependency)
```
### Testing Production Build
```bash
# Clean environment
rm -rf build/ dist/ *.egg-info
# Fresh build
uv tool install --force .
# Test
mycommand --help
```
### Distribution
```bash
# Build wheel
uv build
# Upload to PyPI
uv publish
# Users install
uv tool install mypackage
# (Downloads from PyPI, no source needed)
```
## Common Scenarios
### Scenario 1: Added New Subcommand
**Problem:**
```bash
# Added mypackage/commands/workflows.py
uv tool install --force .
mycommand workflows # Command not found
```
**Why:**
- Entry point might need updating in `pyproject.toml`
- Or file just not in cached wheel
**Solution:**
```bash
# 1. Check entry points
grep -A 5 "\[project.scripts\]" pyproject.toml
# 2. Clean and rebuild
rm -rf build/ dist/ *.egg-info
uv tool install --force .
```
### Scenario 2: Updated Dependency
**Problem:**
```bash
# Updated pyproject.toml dependencies
uv tool install --force .
# Still using old dependency version
```
**Why:**
- Wheel metadata includes dependency list
- Cached wheel has old requirements
**Solution:**
```bash
rm -rf build/ dist/ *.egg-info
uv tool install --force --reinstall-package <dependency> .
```
### Scenario 3: Moved Files
**Problem:**
```bash
# Moved mypackage/utils.py → mypackage/helpers/utils.py
uv tool install --force .
# Import still finds old location
```
**Why:**
- Old wheel still has `mypackage/utils.py`
- New file at `mypackage/helpers/utils.py` not in wheel
**Solution:**
```bash
rm -rf build/ dist/ *.egg-info
uv tool install --force .
```
## Wheel Internals
### Wheel Format
A wheel is a ZIP archive with structure:
```
mypackage-1.0.0-py3-none-any.whl
├── mypackage/ ← Package code
│ ├── __init__.py
│ └── cli.py
└── mypackage-1.0.0.dist-info/ ← Metadata
├── WHEEL ← Wheel version, tags
├── METADATA ← Package info (name, version, deps)
├── RECORD ← File checksums
└── entry_points.txt ← Console scripts
```
### Wheel Naming Convention
```
{distribution}-{version}-{python}-{abi}-{platform}.whl
```
Example: `mypackage-1.0.0-py3-none-any.whl`
- `mypackage` - Distribution name
- `1.0.0` - Version
- `py3` - Python 3 compatible
- `none` - No ABI requirement
- `any` - Any platform
**Pure Python wheels use `py3-none-any`**
**Compiled extensions use specific tags (e.g., `cp311-cp311-macosx_11_0_arm64`)**
## Comparison: Other Package Managers
### npm (Node.js)
```bash
npm install # Installs to node_modules/
npm link # Similar to editable install
```
**npm doesn't cache builds** - packages are just copied
**No build cache issues** - source and installed are always in sync
### cargo (Rust)
```bash
cargo build # Builds to target/
cargo install # Installs from crates.io
```
**cargo caches compiled artifacts** but rebuilds on source changes
**Incremental compilation** - only rebuilds changed files
### pip/uv (Python)
```bash
pip install . # Builds wheel, installs
pip install -e . # Editable install
```
**Caches wheels** - can cause stale installs
**Requires explicit rebuild** for changes to appear
## Summary
**Key Takeaways:**
1. **Wheels are snapshots** - Frozen at build time, don't auto-update
2. **Build artifacts cache** - `build/`, `dist/`, `*.egg-info` persist
3. **`--force` doesn't clean** - Reinstalls but may reuse cached wheel
4. **Editable mode works differently** - Uses symlinks, not copies
5. **`uv run` bypasses install** - Runs directly from source
6. **Clean before rebuild** - Only way to guarantee fresh build
**Mental Model:**
```
Source Code ──build──> Wheel (snapshot) ──install──> Installation
↓ ↑ ↓
Change Cached! Stale!
↓ ↑ ↓
Must clean cache to force rebuild
```
**When in doubt:**
```bash
rm -rf build/ dist/ *.egg-info && uv tool install --force .
```

# UV CLI Reference for Troubleshooting
## Overview
This reference covers UV commands and flags commonly used for troubleshooting package installation and build issues.
## Cache Management
### uv cache clean
Remove all or specific cache entries:
```bash
# Remove ALL cache entries
uv cache clean
# Remove cache for specific package
uv cache clean <package-name>
# Example: Clean numpy cache
uv cache clean numpy
```
**When to use:**
- Suspected stale cache causing installation issues
- After manually editing cache (not recommended)
- When builds succeed locally but fail in CI
### uv cache prune
Remove unused cache entries:
```bash
# Remove all unused cache entries
uv cache prune
# CI-optimized: Remove pre-built wheels, keep source-built wheels
uv cache prune --ci
```
**When to use:**
- Disk space optimization
- CI pipelines (use `--ci` flag)
- After resolving dependency conflicts
**Difference from `clean`:**
- `clean`: Removes everything (or specific package)
- `prune`: Removes only unused entries
- `prune --ci`: Keeps wheels built from source
## Cache Refresh Options
### --refresh
Force revalidation of all cached data:
```bash
# Refresh all dependencies
uv sync --refresh
# Refresh during install
uv pip install --refresh <package>
# Refresh tool installation
uv tool install --refresh <package>
```
**When to use:**
- After package update on PyPI
- Suspected outdated cached metadata
- Testing with latest available versions
### --refresh-package
Target specific package for revalidation:
```bash
# Refresh only numpy
uv sync --refresh-package numpy
# Refresh multiple packages
uv sync --refresh-package numpy --refresh-package pandas
```
**When to use:**
- Know specific package is outdated
- Avoid full cache revalidation overhead
- Testing specific package update
### --reinstall
Ignore existing installed versions:
```bash
# Reinstall everything
uv sync --reinstall
# Reinstall specific package
uv pip install --reinstall <package>
```
**When to use:**
- Installation corrupted
- Different version needed
- Testing clean installation
**Difference from `--refresh`:**
- `--refresh`: Revalidates cache, may reuse if valid
- `--reinstall`: Forces fresh installation regardless
## Build Isolation Control
### --no-build-isolation-package
Disable build isolation for specific packages:
```bash
# Disable isolation for one package
uv pip install --no-build-isolation-package chumpy chumpy
# Disable for multiple packages
uv pip install --no-build-isolation-package pkg1 --no-build-isolation-package pkg2 pkg1 pkg2
```
**When to use:**
- Package build script needs system dependencies
- Import errors during build
- Build backend requires pre-installed modules
**Prerequisite:** Install build dependencies first:
```bash
uv pip install pip setuptools wheel
uv pip install --no-build-isolation-package <package> <package>
```
### --no-build-isolation

- Switching between editable/production modes
- After source code changes (non-editable mode)
### --editable
Install in editable mode:
```bash
# Install current directory as editable
uv tool install --editable .
# Install specific package as editable
uv pip install --editable /path/to/package
```
**When to use:**

```
**When to use:**
- Outdated build dependencies causing failures
- Known incompatible build dependency versions
- Reproducible build environments
### --constraint
Apply version constraints during resolution:
```bash

## Common Troubleshooting Workflows
### Workflow 1: Resolve Build Failure
```bash
# 1. Identify if UV-specific
uv venv -p 3.13 --seed
source .venv/bin/activate
pip install --use-pep517 --no-cache --force-reinstall 'package==version'
# 2. If pip fails too, install build dependencies
apt install build-essential # Ubuntu/Debian
# or
brew install gcc # macOS
# 3. Try again with UV
uv pip install <package>
# 4. If still fails, disable build isolation
uv pip install pip setuptools
uv pip install --no-build-isolation-package <package> <package>
```
### Workflow 2: Fix Stale Cache
```bash
# 1. Clean cache for specific package
uv cache clean <package>
# 2. Force refresh
uv pip install --refresh <package>
# 3. If still issues, clean all cache
uv cache clean
# 4. Reinstall
uv pip install --reinstall <package>
```
### Workflow 3: Debug Tool Installation
```bash
# 1. Uninstall old version
uv tool uninstall <package>
# 2. Clean build artifacts in source
cd /path/to/source
rm -rf build/ dist/ *.egg-info
# 3. Fresh install
uv tool install --force .
# 4. Verify installation
which <command>
<command> --version
```
### Workflow 4: Test Production Build
```bash
# 1. Create clean environment
uv venv test-env
source test-env/bin/activate # or `test-env\Scripts\activate` on Windows
# 2. Install with no cache
uv pip install --no-cache --reinstall <package>
# 3. Test functionality
python -c "import <package>; print(<package>.__version__)"
# 4. Deactivate and cleanup
deactivate
rm -rf test-env

# Writing Scripts
Best practices for Python and Bash automation scripts with language-specific references for deep-dive topics.
## When to Use This Skill
Use this skill when:
- Writing new automation scripts (Python or Bash)
- Debugging subprocess errors and shell parsing issues
- Implementing error handling and validation patterns
- Choosing between Python and Bash for a task
- Setting up script templates with proper structure
## Quick Decision: Python vs Bash
### Use Bash For
- **Simple CLI orchestration** (< 100 lines)
- Piping commands: `grep pattern file | sort | uniq`
- System administration tasks
- Quick file operations
- **Performance-critical shell operations** (3-5x faster than Python)
### Use Python For
- **Complex logic** (> 100 lines)
- Data processing and transformation
- Cross-platform compatibility
- API calls and HTTP requests
- Testing and debugging requirements
### Decision Matrix
| Task | Bash | Python |
|------|------|--------|
| Chain CLI tools | ✅ | ❌ |
| < 100 lines | ✅ | 🟡 |
| Data manipulation | ❌ | ✅ |
| Cross-platform | ❌ | ✅ |
| Testing needed | ❌ | ✅ |
| Complex logic | ❌ | ✅ |
| API calls | 🟡 | ✅ |
## Core Principles
### 1. Safety First
- Always implement error handling (Python: try/except, Bash: set -Eeuo pipefail)
- Provide dry-run mode for destructive operations
- Create automatic backups before modifications
- Validate inputs and check for required commands
### 2. Self-Documenting Output
- Print clear progress messages
- Show what the script is doing at each step
- Use structured output (headers, separators)
- Write errors to stderr, not stdout
### 3. Maintainability
- Keep scripts under 500 lines (split if larger)
- Use functions for repeated logic
- Document non-obvious patterns
- Include usage examples in help text
## Language-Specific References
For detailed patterns and examples, read the appropriate reference file:
### Python Reference (`references/python.md`)
Load when working with Python scripts. Contains:
- Subprocess patterns (two-stage, avoiding shell=True)
- Debugging subprocess failures
- Error handling with try/except
- Argparse patterns for CLI arguments
- Environment variable management
- File processing patterns
- URL verification examples
- Common pitfalls and solutions
**Read this when:** Writing Python scripts, debugging subprocess issues, setting up CLI arguments
### Bash Reference (`references/bash.md`)
Load when working with Bash scripts. Contains:
- Error handling (set -Eeuo pipefail, trap)
- String escaping for LaTeX and special characters
- Variable quoting rules
- Function patterns and documentation
- Script directory detection
- Configuration file loading
- Parallel processing patterns
- Common pitfalls (unquoted variables, escape sequences)
**Read this when:** Writing Bash scripts, handling LaTeX generation, debugging string escaping issues
## Common Patterns Across Languages
### Dry-Run Mode
Provide a way to preview changes before applying:
**Python:**
```python
parser.add_argument('--force', action='store_true',
help='Apply changes (dry-run by default)')
args = parser.parse_args()
dry_run = not args.force
if dry_run:
print(f"→ Would rename {old} → {new}")
else:
print(f"✓ Renamed {old} → {new}")
apply_change()
```
**Bash:**
```bash
DRY_RUN=true
[[ "${1}" == "--force" ]] && DRY_RUN=false
if $DRY_RUN; then
echo "→ Would delete $file"
else
echo "✓ Deleted $file"
rm "$file"
fi
```
### Automatic Backups
Create timestamped backups before modifications:
**Python:**
```python
from datetime import datetime
import shutil
timestamp = datetime.now().strftime('%Y%m%d_%H%M%S')
backup_path = f"{config_path}.backup.{timestamp}"
shutil.copy2(config_path, backup_path)
print(f"✓ Backup created: {backup_path}")
```
**Bash:**
```bash
backup_file="${config}.backup.$(date +%Y%m%d_%H%M%S)"
cp "$config" "$backup_file"
echo "✓ Backup created: $backup_file"
```
### Check Required Commands
**Python:**
```python
import shutil
if not shutil.which('jq'):
print("Error: jq is required but not installed", file=sys.stderr)
sys.exit(1)
```
**Bash:**
```bash
if ! command -v jq &> /dev/null; then
echo "Error: jq is required but not installed" >&2
exit 1
fi
```
## Validation Tools
### Python
```bash
python3 -m py_compile script.py # Check syntax
pylint script.py # Lint
black script.py # Format
mypy script.py # Type check
```
### Bash
```bash
bash -n script.sh # Check syntax
shellcheck script.sh # Static analysis
bash -x script.sh # Debug mode
```
## How to Use This Skill
1. **Start here** - Use the decision matrix to choose Python or Bash
2. **Read language reference** - Load `references/python.md` or `references/bash.md` for detailed patterns
3. **Apply core principles** - Implement safety, documentation, and maintainability patterns
4. **Validate** - Run syntax checkers and linters before using the script
The references contain detailed code examples, debugging workflows, and common pitfalls specific to each language. Load them as needed to avoid cluttering context when working on single-language scripts.

# Bash Scripting Reference
Detailed patterns and examples for Bash automation scripts.
## Error Handling
### Essential Settings
Put these at the top of **every** Bash script:
```bash
#!/usr/bin/env bash
set -Eeuo pipefail
trap cleanup SIGINT SIGTERM ERR EXIT
cleanup() {
trap - SIGINT SIGTERM ERR EXIT
# Cleanup code here (remove temp files, etc.)
}
```
### Flag Breakdown
**`-E` (errtrap):** Error traps work in functions
```bash
trap 'echo "Error"' ERR
func() { false; } # Trap fires (wouldn't without -E)
```
**`-e` (errexit):** Stop on first error
```bash
command_fails # Script exits here
never_runs # Never executes
```
**`-u` (nounset):** Catch undefined variables
```bash
echo "$TYPO" # Error: TYPO: unbound variable (not silent)
```
**`-o pipefail`:** Detect failures in pipes
```bash
false | true # Fails (not just last command status)
```
**`trap`:** Run cleanup on exit/error/signal
## String Escaping for LaTeX and Special Characters
**Problem:** Bash interprets escape sequences in double-quoted strings, which corrupts LaTeX commands and special text.
**Dangerous sequences:** `\b` (backspace), `\n` (newline), `\t` (tab), `\r` (return)
### Example Failure
```bash
# ❌ Wrong: Creates backspace character
echo "\\begin{document}" >> file.tex # Becomes: <backspace>egin{document}
echo "\\bibliographystyle{ACM}" >> file.tex # Becomes: <backspace>ibliographystyle{ACM}
```
### Safe Approaches
**1. Single quotes** (Best for simple cases):
```bash
echo '\begin{document}' >> file.tex # ✅ No interpretation
echo '\bibliographystyle{ACM-Reference-Format}' >> file.tex # ✅ Safe
```
**2. Double backslashes** (When variables needed):
```bash
echo "\\\\begin{document}" >> file.tex # ✅ 4 backslashes → \b
cmd="begin"
echo "\\\\${cmd}{document}" >> file.tex # ✅ Works with variables
```
**3. Printf** (More predictable):
```bash
printf '%s\n' '\begin{document}' >> file.tex # ✅ Literal strings
printf '%s\n' '\bibliographystyle{ACM-Reference-Format}' >> file.tex
```
**4. Heredoc** (Best for multi-line LaTeX):
```bash
cat >> file.tex << 'EOF' # ✅ Note quoted delimiter
\begin{document}
\section{Title}
\bibliographystyle{ACM-Reference-Format}
\end{document}
EOF
```
### Quick Reference
| Character | Echo double-quotes | Echo single-quotes | Heredoc |
|-----------|-------------------|-------------------|---------|
| `\b` | ❌ Backspace | ✅ Literal | ✅ Literal |
| `\n` | ❌ Newline | ✅ Literal | ✅ Literal |
| `\t` | ❌ Tab | ✅ Literal | ✅ Literal |
| Variables | ✅ Work | ❌ Don't expand | ✅ With `"EOF"` |
**Rule of thumb:** For LaTeX, use single quotes or heredocs to avoid escape sequence interpretation.
## Variable Quoting
### Always Quote Variables
```bash
# ✅ Always quote variables
file="my file.txt"
cat "$file" # Correct
# ❌ Unquoted breaks on spaces
cat $file # WRONG: tries to cat "my" and "file.txt"
```
### Array Expansion
```bash
files=("file 1.txt" "file 2.txt")
# ✅ Quote array expansion
for file in "${files[@]}"; do
echo "$file"
done
# ❌ Unquoted splits on spaces
for file in ${files[@]}; do
echo "$file" # WRONG: treats spaces as separators
done
```
## Script Directory Detection
```bash
# Get directory where script is located
script_dir=$(cd "$(dirname "${BASH_SOURCE[0]}")" &>/dev/null && pwd -P)
# Use for relative paths
source "${script_dir}/config.sh"
data_file="${script_dir}/../data/input.txt"
```
## Functions
### Function Template
```bash
# Document functions with comments
# Args:
# $1 - input file
# $2 - output file
# Returns:
# 0 on success, 1 on error
process_file() {
local input="$1"
local output="$2"
if [[ ! -f "$input" ]]; then
echo "Error: Input file not found: $input" >&2
return 1
fi
# Process file
grep pattern "$input" > "$output"
}
# Call function
if process_file "input.txt" "output.txt"; then
echo "Success"
else
echo "Failed" >&2
exit 1
fi
```
### Local Variables
Always use `local` for function variables:
```bash
process_data() {
local data="$1" # ✅ Local to function
local result
result=$(transform "$data")
echo "$result"
}
```
## Error Messages
### Write Errors to Stderr
```bash
# ✅ Write errors to stderr
echo "Error: File not found" >&2
# ✅ Exit with non-zero code
exit 1
# ❌ Don't write errors to stdout
echo "Error: File not found"
```
### Structured Error Handling
```bash
error() {
echo "Error: $*" >&2
exit 1
}
warn() {
echo "Warning: $*" >&2
}
# Usage
[[ -f "$config" ]] || error "Config file not found: $config"
[[ -w "$output" ]] || warn "Output file not writable: $output"
```
## Checking Commands Exist
```bash
if ! command -v jq &> /dev/null; then
echo "Error: jq is required but not installed" >&2
exit 1
fi
# Check multiple commands
for cmd in curl jq sed; do
if ! command -v "$cmd" &> /dev/null; then
echo "Error: $cmd is required but not installed" >&2
exit 1
fi
done
```
## Parallel Processing
```bash
# Run commands in parallel, wait for all
for file in *.txt; do
process_file "$file" &
done
wait
echo "All files processed"
```
### Parallel with Error Handling
```bash
pids=()
for file in *.txt; do
process_file "$file" &
pids+=($!)
done
# Wait and check exit codes
failed=0
for pid in "${pids[@]}"; do
if ! wait "$pid"; then
((failed++))
fi
done
if [[ $failed -gt 0 ]]; then
echo "Error: $failed jobs failed" >&2
exit 1
fi
```
## Configuration Files
### Loading Config
```bash
# Load config file if exists
config_file="${script_dir}/config.sh"
if [[ -f "$config_file" ]]; then
source "$config_file"
else
# Default values
LOG_DIR="/var/log"
BACKUP_DIR="/backup"
fi
```
### Safe Config Sourcing
```bash
# Validate config before sourcing
validate_config() {
local config="$1"
# Check syntax
if ! bash -n "$config" 2>/dev/null; then
echo "Error: Invalid syntax in $config" >&2
return 1
fi
return 0
}
if validate_config "$config_file"; then
source "$config_file"
else
exit 1
fi
```
## Argument Parsing
### Simple Pattern
```bash
# Parse flags
VERBOSE=false
FORCE=false
while [[ $# -gt 0 ]]; do
case "$1" in
-v|--verbose)
VERBOSE=true
shift
;;
-f|--force)
FORCE=true
shift
;;
-o|--output)
OUTPUT="$2"
shift 2
;;
*)
echo "Unknown option: $1" >&2
exit 1
;;
esac
done
```
### Usage Function
```bash
usage() {
cat << EOF
Usage: $0 [OPTIONS] INPUT OUTPUT
Process files with various options.
OPTIONS:
-v, --verbose Verbose output
-f, --force Force operation
-o, --output Output file
-h, --help Show this help
EXAMPLES:
$0 input.txt output.txt
$0 -v --force input.txt output.txt
EOF
}
# Show usage on error or -h
[[ "$1" == "-h" || "$1" == "--help" ]] && usage && exit 0
[[ $# -lt 2 ]] && usage && exit 1
```
## Temporary Files
### Safe Temp File Creation
```bash
# Create temp file
tmpfile=$(mktemp)
trap "rm -f '$tmpfile'" EXIT
# Use temp file
curl -s "$url" > "$tmpfile"
process "$tmpfile"
# Cleanup happens automatically via trap
```
### Temp Directory
```bash
# Create temp directory
tmpdir=$(mktemp -d)
trap "rm -rf '$tmpdir'" EXIT
# Use temp directory
download_files "$tmpdir"
process_directory "$tmpdir"
```
## Common Patterns
### File Existence Checks
```bash
# Check file exists
[[ -f "$file" ]] || error "File not found: $file"
# Check directory exists
[[ -d "$dir" ]] || error "Directory not found: $dir"
# Check file readable
[[ -r "$file" ]] || error "File not readable: $file"
# Check file writable
[[ -w "$file" ]] || error "File not writable: $file"
```
### String Comparisons
```bash
# Check empty string
[[ -z "$var" ]] && error "Variable is empty"
# Check non-empty string
[[ -n "$var" ]] || error "Variable not set"
# String equality
[[ "$a" == "$b" ]] && echo "Equal"
# Pattern matching
[[ "$file" == *.txt ]] && echo "Text file"
```
### Numeric Comparisons
```bash
# Greater than
[[ $count -gt 10 ]] && echo "More than 10"
# Less than or equal
[[ $count -le 5 ]] && echo "5 or fewer"
# Equal
[[ $count -eq 0 ]] && echo "Zero"
```
## Common Pitfalls
### ❌ Unquoted Variables
```bash
file=$1
cat $file # Breaks with spaces
```
### ✅ Always Quote
```bash
file="$1"
cat "$file"
```
### ❌ Escape Sequences in LaTeX
```bash
# Corrupts \begin, \bibitem, etc.
echo "\\begin{document}" >> file.tex # Creates <backspace>egin
```
### ✅ Use Single Quotes or Heredocs
```bash
echo '\begin{document}' >> file.tex
# Or:
cat >> file.tex << 'EOF'
\begin{document}
EOF
```
### ❌ No Error Handling
```bash
#!/bin/bash
command_that_might_fail
continue_anyway
```
### ✅ Fail Fast
```bash
#!/usr/bin/env bash
set -Eeuo pipefail
command_that_might_fail # Script exits on failure
```
### ❌ Unvalidated User Input
```bash
rm -rf /$user_input # DANGER
```
### ✅ Validate Input
```bash
# Validate directory name
if [[ ! "$user_input" =~ ^[a-zA-Z0-9_-]+$ ]]; then
error "Invalid directory name"
fi
```
## Validation Tools
```bash
# Check syntax
bash -n script.sh
# Static analysis with shellcheck
brew install shellcheck # macOS
apt install shellcheck # Ubuntu
shellcheck script.sh
# Run with debug mode
bash -x script.sh
```

# Python Scripting Reference
Detailed patterns and examples for Python automation scripts.
## Subprocess Patterns
### Two-Stage Subprocess (Avoid Shell Parsing)
**Problem:** Using `shell=True` with complex patterns causes shell parsing issues.
**❌ Don't: shell=True with complex patterns**
```python
cmd = 'curl -s "url" | grep -oE "pattern(with|parens)"'
subprocess.run(cmd, shell=True, ...)
```
**✅ Do: Separate calls with input= piping**
```python
curl_result = subprocess.run(['curl', '-s', url],
capture_output=True, text=True)
grep_result = subprocess.run(['grep', '-oE', pattern],
input=curl_result.stdout,
capture_output=True, text=True)
```
### Why List Arguments Work
- Python executes command directly (no shell interpretation)
- Arguments passed as literal strings
- Special chars like `|(){}` treated as text, not operators
### When shell=True Is Needed
Only use for hard-coded commands that require shell features:
- `*` wildcards
- `~` home directory expansion
- `&&` operators
- Environment variable expansion
```python
# Hard-coded command only
subprocess.run('ls *.txt | wc -l', shell=True, ...)
```
## Debugging Subprocess Failures
### Workflow
1. **Test command in bash first** - Verify it works outside Python
2. **Add debug output:**
```python
result = subprocess.run(cmd, ...)
print(f"stdout: {result.stdout[:100]}")
print(f"stderr: {result.stderr}")
print(f"returncode: {result.returncode}")
```
3. **Check stderr for shell errors** - Syntax errors indicate shell parsing issues
4. **Rewrite without shell=True** - Use list arguments and two-stage pattern
### Common Errors
| Error | Cause | Solution |
|-------|-------|----------|
| `syntax error near unexpected token '('` | Shell parsing regex/parens | Two-stage subprocess |
| `command not found` | PATH issue or typo | Check command exists with `which` |
| Empty stdout | Command construction error | Debug with stderr output |
### Debugging Invisible Characters
**Problem:** Files with invisible characters (backspace, null bytes) cause mysterious errors.
**Symptoms:**
- LaTeX: `Unicode character ^^H (U+0008) not set up for use with LaTeX`
- Commands fail with "invalid character" but file looks normal
**Detection:**
```bash
# Show all characters including invisible ones
od -c file.txt
# Check specific line range
sed -n '10,20p' file.txt | od -c
# Find backspaces
grep -P '\x08' file.txt
```
**Example output:**
```
0000000 % % f i l e . \n \b \ b e g i
^^^ backspace character
```
**Fix:**
```bash
# Remove all backspace characters
tr -d '\b' < corrupted.tex > clean.tex
# Remove all control characters (preserve newlines)
tr -cd '[:print:]\n' < file.txt > clean.txt
```
**Prevention:** Use proper quoting when generating files (see Bash reference for LaTeX string escaping).
## Error Handling
### Basic Pattern
```python
import sys
import subprocess
try:
result = subprocess.run(['command'],
capture_output=True,
text=True,
check=True) # Raises on non-zero exit
except subprocess.CalledProcessError as e:
print(f"Error: Command failed with exit code {e.returncode}", file=sys.stderr)
print(f"stderr: {e.stderr}", file=sys.stderr)
sys.exit(1)
except FileNotFoundError:
print("Error: Command not found in PATH", file=sys.stderr)
sys.exit(1)
```
### File Operations
```python
try:
with open(file_path, 'r') as f:
content = f.read()
except FileNotFoundError:
print(f"Error: File not found: {file_path}", file=sys.stderr)
sys.exit(1)
except PermissionError:
print(f"Error: Permission denied: {file_path}", file=sys.stderr)
sys.exit(1)
except IOError as e:
print(f"Error reading file: {e}", file=sys.stderr)
sys.exit(1)
```
## Argparse Patterns
### Multi-Mode Scripts
```python
import argparse
parser = argparse.ArgumentParser(description='Script description')
parser.add_argument('input', nargs='?', help='Input file or topic')
parser.add_argument('--url', help='Direct URL mode')
parser.add_argument('--verify', action='store_true', help='Verify output')
args = parser.parse_args()
# Validate combinations
if not args.input and not args.url:
parser.error("Provide either input or --url")
```
### Common Flag Patterns
```python
parser.add_argument('-v', '--verbose', action='store_true',
help='Verbose output')
parser.add_argument('-f', '--force', action='store_true',
help='Force operation')
parser.add_argument('-o', '--output', default='output.txt',
help='Output file')
parser.add_argument('--count', type=int, default=5,
help='Number of items')
parser.add_argument('--config', type=str,
help='Config file path')
```
### Mutually Exclusive Groups
```python
group = parser.add_mutually_exclusive_group()
group.add_argument('--json', action='store_true')
group.add_argument('--yaml', action='store_true')
```
## Environment Variables
```python
import os
# ✅ Never hardcode credentials
API_KEY = os.getenv('API_KEY')
if not API_KEY:
print("Error: API_KEY environment variable not set", file=sys.stderr)
sys.exit(1)
# ✅ Provide defaults
LOG_LEVEL = os.getenv('LOG_LEVEL', 'INFO')
OUTPUT_DIR = os.getenv('OUTPUT_DIR', './output')
# ✅ Type conversion with defaults
MAX_RETRIES = int(os.getenv('MAX_RETRIES', '3'))
TIMEOUT = float(os.getenv('TIMEOUT', '30.0'))
```
## File Processing Patterns
### Process Files Matching Pattern
```python
import glob
import sys
def process_files(pattern: str) -> list[str]:
"""Find and process files matching pattern."""
files = glob.glob(pattern, recursive=True)
results = []
for file in files:
try:
with open(file, 'r') as f:
content = f.read()
results.append(process(content))
except IOError as e:
print(f"Error reading {file}: {e}", file=sys.stderr)
return results
```
### Safe File Writing
```python
import tempfile
import shutil
def safe_write(file_path: str, content: str):
"""Write to temp file first, then atomic move."""
# Write to temp file in same directory
dir_name = os.path.dirname(file_path)
with tempfile.NamedTemporaryFile(mode='w', dir=dir_name,
delete=False) as tmp:
tmp.write(content)
tmp_path = tmp.name
# Atomic move
shutil.move(tmp_path, file_path)
```
## URL Verification
```python
import subprocess
def verify_url(url: str) -> bool:
"""Verify URL is accessible with HTTP HEAD request."""
result = subprocess.run(['curl', '-I', '-s', url],
capture_output=True, text=True)
if 'HTTP/2 200' in result.stdout or 'HTTP/1.1 200' in result.stdout:
if 'content-type:' in result.stdout.lower():
return True
return False
```
## Automation Script Patterns
### Dry-Run Mode
```python
import argparse
parser = argparse.ArgumentParser()
parser.add_argument('--force', action='store_true',
help='Apply changes (dry-run by default)')
args = parser.parse_args()
dry_run = not args.force
# Use dry_run flag throughout script
for item in items:
change_description = f"Would rename {item['old']} → {item['new']}"
if dry_run:
print(f"→ {change_description}")
else:
print(f"✓ {change_description}")
apply_change(item)
```
### Backup-First Pattern
```python
from datetime import datetime
import shutil
def backup_before_modify(config_path: str) -> str:
"""Create timestamped backup before modifications."""
timestamp = datetime.now().strftime('%Y%m%d_%H%M%S')
backup_path = f"{config_path}.backup.{timestamp}"
shutil.copy2(config_path, backup_path)
print(f"✓ Backup created: {backup_path}")
return backup_path
# Use in operations
if not dry_run:
backup_before_modify(config_path)
update_config(config_path)
```
### Self-Documenting Output
```python
print("=" * 70)
print("CONFIGURATION MIGRATION")
print("=" * 70)
print()
print("Step 1: Analyzing input files")
print("-" * 70)
files = find_files()
print(f"Found: {len(files)} files")
for f in files[:5]:
print(f" • {f}")
print()
print("Step 2: Validating configuration")
print("-" * 70)
errors = validate_config()
if errors:
print(f"✗ Found {len(errors)} errors")
for error in errors:
print(f" • {error}")
else:
print("✓ Configuration valid")
```
## Common Pitfalls
### ❌ Using shell=True Unnecessarily
```python
# Vulnerable and error-prone
subprocess.run(f'rm -rf {user_input}', shell=True) # DANGER
```
### ✅ Use List Arguments
```python
subprocess.run(['rm', '-rf', user_input]) # Safe
```
### ❌ Not Handling Encoding
```python
result = subprocess.run(['cmd'], capture_output=True)
print(result.stdout) # bytes, not string
```
### ✅ Specify text=True
```python
result = subprocess.run(['cmd'], capture_output=True, text=True)
print(result.stdout) # string
```
### ❌ Ignoring Errors
```python
result = subprocess.run(['cmd'])
# No error handling
```
### ✅ Check Exit Code
```python
result = subprocess.run(['cmd'], capture_output=True, text=True)
if result.returncode != 0:
print(f"Error: {result.stderr}", file=sys.stderr)
sys.exit(1)
```
## Validation Tools
```bash
# Check syntax
python3 -m py_compile script.py
# Lint with pylint
pip install pylint
pylint script.py
# Format with black
pip install black
black script.py
# Type check with mypy
pip install mypy
mypy script.py
```
