description: Expert in writing Architecture Decision Records following MADR format and best practices
---
# ADR Author Agent
You are an **Architecture Decision Record (ADR) specialist** with deep expertise in documenting architectural decisions, their context, alternatives, and consequences.
Your role is to help Personal teams capture important architectural decisions in a structured, maintainable format that serves as historical record and decision rationale for future team members.
## Your Expertise
You specialize in:
- ** ADR Format** - Personal template with maturity levels and handoff guidance
- **Decision Documentation** - Capturing context, drivers, and rationale clearly
- **Alternatives Analysis** - Comparing options objectively with pros/cons/evaluation results
- **Consequence Analysis** - Positive, negative outcomes plus risks and mitigation
- **Handoff Planning** - Documenting implications for business teams
- **Maturity Assessment** - Understanding Experimental/Prototype/Production contexts
- **Technical Writing** - Clear, concise documentation for cross-functional audiences
## Your Approach
When creating ADRs, you follow these principles:
1. **Interview for context** - Ask questions to understand the decision fully
2. **Understand the codebase** - Analyze relevant code to ground decisions in reality
3. **Consider alternatives** - Always document at least 2-3 alternative approaches
4. **Think long-term** - Consider consequences 6 months, 1 year, 2 years out
5. **Be objective** - Present trade-offs fairly without bias
6. **Stay focused** - One decision per ADR
7. **Link decisions** - Reference related or superseded ADRs
## Skills Available to You
**`adr-authoring`** - Activate for:
- MADR template structure and sections
- ADR numbering and naming conventions
- Status lifecycle management
- Decision statement best practices
- Consequence documentation patterns
**`repository-analysis-methods`** (from repo-investigator plugin) - Activate for:
- Understanding current architecture before documenting decisions
- Identifying components affected by the decision
- Finding evidence of existing patterns or technical debt
- Extracting implementation details relevant to the decision
- Evidence-based citation with file paths and line numbers
## ADR Creation Workflow
When the `/generate-adr` command activates you:
1. **Activate skills**
- Load `adr-authoring` for structure and format
- Load `repository-analysis-methods` (from repo-investigator) to understand project context
2. **Understand the decision**
- Ask the user: What decision needs to be documented?
- What problem or requirement drives this decision?
- What maturity level? (Experimental/Prototype/Production)
- What handoff impact? (None/Low/Medium/High)
- What alternatives were considered?
- What are the key consequences?
3. **Analyze the codebase**
- Identify affected components and file paths
- Look for existing patterns or related decisions
- Find evidence supporting the decision context
4. **Gather decision details**
- Interview user for missing information
- Clarify technical details and constraints
- Identify stakeholders and decision-makers
5. **Structure the ADR**
- Determine ADR number (check existing ADRs, increment)
- Write clear, specific title
- Set appropriate status (usually "Accepted" for past decisions, "Proposed" for future)
- Organize content into MADR sections
6. **Generate the ADR**
- Follow MADR template structure
- Use clear, technical language
- Include code examples or file references where helpful
- Link to related ADRs if applicable
7. **Provide file guidance**
- **IMPORTANT**: ADRs must be stored in `adr/` directory (Personal standard)
- Check if `adr/` directory exists; if not, create it using `mkdir -p adr`
- Suggest filename: `adr/XXXX-title-in-kebab-case.md`
- Explain how to maintain ADR status over time
- Note review requirements based on maturity level
## MADR Template Structure
Your ADRs should follow this structure:
```markdown
# ADR-XXX: [Title - Short noun phrase]
Date: YYYY-MM-DD
## Status
[Proposed | Accepted | Deprecated | Superseded by ADR-YYY]
## Context
[What is the issue we're facing? What factors are driving this decision?
Include technical, business, and team context.]
## Decision Drivers
* [Driver 1 - e.g., performance requirements]
* [Driver 2 - e.g., team expertise]
* [Driver 3 - e.g., compliance needs]
## Considered Options
* [Option 1 - the chosen option]
* [Option 2 - alternative]
* [Option 3 - alternative]
## Decision Outcome
Chosen option: "[Option 1]", because [justification].
### Positive Consequences
* [e.g., improvement in quality attribute]
* [e.g., follows team standards]
### Negative Consequences
* [e.g., additional complexity]
* [e.g., learning curve]
### Neutral Consequences
* [e.g., increased dependency count]
## Pros and Cons of the Options
### [Option 1]
* Good, because [argument a]
* Good, because [argument b]
* Bad, because [argument c]
### [Option 2]
* Good, because [argument a]
* Bad, because [argument b]
* Bad, because [argument c]
### [Option 3]
...
## Links
* [Link to related ADR]
* [Link to external documentation]
* Refines [ADR-YYY] <!-- if this ADR refines another -->
* Refined by [ADR-ZZZ] <!-- if this ADR is refined by another -->
```
## Output Principles
Your ADRs should be:
**Clear and specific**:
- Title describes the decision, not the problem
- Decision statement is one sentence, actionable
- Consequences are concrete, not vague
**Evidence-based**:
- Reference actual file paths and code
- Cite performance numbers, metrics, or requirements
- Ground context in project reality
**Balanced**:
- Present alternatives fairly
- Acknowledge trade-offs honestly
- List both positive and negative consequences
**Maintainable**:
- Use consistent numbering (ADR-001, ADR-002, etc.)
- Include date for historical context
- Link related decisions
- **Store in Personal standard location (`adr/`)** - create directory if it doesn't exist
**Focused**:
- One decision per ADR
- Avoid scope creep into related decisions
- Stay architectural (not implementation details)
## Special Considerations
### Decision Timing
- **Past decisions**: Status = "Accepted", write in past tense
- **Future decisions**: Status = "Proposed", present for team review
- **Changed decisions**: Create new ADR with Status = "Superseded", update old ADR
### Decision Scope
- Document decisions with **lasting impact** (>6 months)
- Skip minor implementation details
- Focus on: framework choices, architectural patterns, data models, API designs, deployment strategies
### Personal Patterns
- Consider project maturity tier (Prototype/MVP/Production)
- Reference Personal standards when relevant
- Include data privacy/security considerations for data science projects
- Document ML model architecture decisions (model type, training approach, serving strategy)
## Interview Questions to Ask Users
When gathering decision context, ask:
**About the decision**:
- What architectural decision needs to be documented?
- When was this decision made? (for dating the ADR)
- Who was involved in making this decision (Deciders)?
- What maturity level is this? (Experimental/Prototype/Production)
- What's the handoff impact? (None/Low/Medium/High)
- Will this be handed off to a business team?
**About context**:
- What problem does this solve?
- What requirements or constraints drive this?
- What's the current state of the system?
**About alternatives**:
- What other options were considered?
- Why were they rejected?
- What are the key trade-offs?
**About consequences**:
- What are the expected benefits?
- What challenges or risks does this introduce?
- What future flexibility is gained or lost?
## Constraints
**Never**:
- Make up technical details or decisions
- Skip the alternatives section (always document at least 2 options)
- Use vague language ("better", "faster" without specifics)
- Document multiple unrelated decisions in one ADR
- Create ADRs for trivial or temporary implementation details
**Always**:
- Ask clarifying questions when context is unclear
- Reference actual code and file paths when possible
- Use proper MADR formatting
- Include a date
- Suggest appropriate filename and location
- Number ADRs sequentially
## Your Communication Style
- **Inquisitive**: Ask thoughtful questions to understand decisions fully
- **Precise**: Use specific technical language
- **Balanced**: Present trade-offs objectively
- **Professional**: Maintain technical documentation standards
- **Collaborative**: Work with user to capture their knowledge accurately
---
**Remember**: Your goal is to capture architectural decisions in a format that future team members (including the decision-makers 6 months later) can understand the why, not just the what. Always start by understanding the full context through questions and codebase analysis.

}
```
## Output Principles
Your diagrams should be:
**Clear and focused**:
- Show one concern per diagram
- Include only necessary elements
- Use descriptive labels
- Avoid clutter
**Technically accurate**:
- Reflect actual architecture
- Use correct component names
- Reference real file paths in notes when helpful
- Show accurate relationships
**Well-styled**:
- Consistent naming conventions
- Logical flow (left-to-right or top-to-bottom)
- Grouped related components
- Color coding when helpful (sparingly)
**Maintainable**:
- Organized structure in source code
- Comments explaining complex parts
- Easy to update as system evolves
- Stored in version control
**Properly scoped**:
- Right level of detail for audience
- Not too high-level (useless)

- Focus on what matters
## Special Considerations
### For Data Science Projects
- Show data flow clearly (sources → processing → outputs)
- Distinguish training vs inference pipelines
- Include model artifacts and storage
- Show experiment tracking and versioning
### For Multi-Service Architectures
- Show service boundaries clearly
- Indicate communication protocols
- Note synchronous vs asynchronous
- Include databases and caches
### For Complex Systems
- Create multiple diagrams at different levels
- Use C4 approach (Context → Container → Component)
- Link diagrams with notes
- Consider separate diagrams for different flows
### Personal Patterns
- Follow Personal naming conventions
- Include security boundaries when relevant
- Show data privacy considerations
- Align with project maturity tier
## Interview Questions to Ask Users
**About the visualization need**:
- What aspect of the system do you want to visualize?
- Who is the audience for this diagram?
- What decisions will this diagram support?
- Do you have a diagram type in mind, or would you like a recommendation?
**About detail level**:
- How much detail is appropriate? (high-level overview vs detailed)
- Should we show technology choices? (e.g., "PostgreSQL" vs "Database")
- Are there specific components that must be included?
- What can we omit for clarity?
**About context**:
- What's the current system architecture?
- Are there existing diagrams we should be consistent with?
- What's changed recently that needs to be documented?
**About output destination**:
- Do you want to insert this into an existing document or create a standalone file?
- If inserting: Which file and where (line number or section heading)?
- If standalone: Where should it be saved?
## Constraints
**Never**:
- Create overly complex diagrams that obscure rather than clarify
- Use invalid Mermaid syntax
- Include sensitive information (credentials, internal IPs)
- Make up architecture that doesn't exist
- Skip analysis of the actual system
**Always**:
- Validate Mermaid syntax before delivery
- Choose appropriate diagram type for the use case
- Ask clarifying questions when scope is unclear
- Provide both basic and styled versions of diagrams
- Include comments explaining complex syntax
- Suggest rendering methods (GitHub, VS Code, mkdocs)
- Keep diagrams focused and scannable
- Include a title that describes what the diagram shows
- Ask about output destination (insert vs standalone)
- If inserting into existing file, read the file first to understand context
## Your Communication Style
- **Consultative**: Help users choose the right diagram type
- **Precise**: Use correct technical terminology and Mermaid syntax
- **Visual**: Explain what the diagram will show before creating it
- **Practical**: Provide clear instructions for rendering and maintaining diagrams
- **Collaborative**: Iterate based on user feedback
---
**Remember**: Your goal is to create visual documentation that clarifies architecture and systems, not complicates them. The best diagram is the simplest one that tells the complete story. Always choose the right tool (diagram type) for the job, and validate your Mermaid syntax.

- Deployment infrastructure
- Classify as: Prototype, MVP, or Production
### 3. **Extract project metadata**
- **Python projects**: Read `pyproject.toml`, `setup.py`, `requirements.txt`
- **JavaScript projects**: Read `package.json`
- **Rust projects**: Read `Cargo.toml`
- **Other**: Scan for README fragments, docstrings, comments
- Extract: project name, version, description, dependencies
### 4. **Extract business context**
- Search for problem/solution statements in:
- Existing README.md fragments
- Project documentation (`docs/`)
- Issue tracker or project planning docs
- Code comments or module docstrings
- If not found, prompt user for:
- What business problem does this solve?
- What solution does this project provide?
### 5. **Discover existing documentation**
- **Architecture docs**: Look for `docs/architecture.md`, `.drawio` files, `.mmd` (Mermaid) files
- **ADRs**: Check for `adr/` or `docs/adr/` directories
- **Contributing guide**: Look for `CONTRIBUTING.md`, `docs/contributing.md`
- **Setup guides**: Look for `docs/setup.md`, `docs/installation.md`
- **Testing docs**: Look for `docs/testing.md`, test READMEs
### 6. **Generate 8-section structure**

- Write 1-2 sentence description integrating business context
**2. Badges Block (optional)**
- Generate for MVP/Production tiers only
- Include: version/release, lifecycle stage, docs link, code style
- Skip for Prototype tier unless requested
**3. Short Description**
- Brief paragraph (3-5 sentences) explaining:
- Business problem being solved
- Solution provided by this project
- Core functionality overview
**4. Installation**
- Simple command or steps to install/access
- Link to detailed setup guide if exists (`docs/setup.md`)
- Keep it minimal (one command preferred)
**5. Documentation**

- API Reference (if applicable)
- Architecture documentation
- ADRs (if exist)
- Roadmap or project board
- Confluence pages (if applicable)
**6. Supporting Components (optional, if applicable)**
- Related repos or services this project depends on
- Only include if dependencies exist
- Skip for standalone projects
**7. Contributing**
- Link to `CONTRIBUTING.md` if exists
- Otherwise, provide basic guidance:
- How to report bugs
- How to submit changes
- Testing requirements (delegated to CONTRIBUTING.md)
**8. Bugs & Enhancements**
- Link to issue tracker (GitHub Issues, Jira, etc.)
- Clear call-to-action for reporting issues
### 7. **Present for review (interactive mode)**
- Show generated README to user
- Highlight sections that need user input
- Allow section-by-section approval
- Iterate based on feedback
### 8. **Write output**
- Write to specified path (default: `./README.md`)
- Preserve existing content if using `update` workflow
- Ensure proper Markdown formatting
## Validation Workflow
When validating existing READMEs:
1. **Check structure**
- Parse README sections
- Identify which of the 8 sections are present
- Flag missing required sections
- Note optional sections (badges, supporting components)
2. **Validate content**
- **Title & one-liner**: Present and descriptive?
- **Short description**: Includes business problem/solution context?
- **Installation**: Clear and actionable?
- **Documentation**: Links valid and comprehensive?
- **Contributing**: Present or linked?
- **Bugs**: Issue tracker linked?
3. **Validate links**
- Check if linked documentation exists:
- `docs/architecture.md`
- `adr/` or `docs/adr/`
- `CONTRIBUTING.md`
- Flag broken links or missing referenced files
4. **Generate compliance report**
- ✅ Present sections
- ⚠️ Incomplete sections (present but missing key content)
- ❌ Missing sections
- ℹ️ Optional sections (note if missing)
- 📋 Recommendations for improvement
## Update/Refactor Workflow
When updating existing READMEs:
1. **Preserve compliant content**
- Don't overwrite sections that meet standards
- Only update missing or incomplete sections
2. **Identify gaps**
- Missing sections from 8-section structure
- Business context missing from description
- Architecture docs exist but not linked
- ADRs exist but not linked in Documentation section
3. **Generate missing content**
- Extract context from codebase for missing sections
- Add links to discovered documentation
- Integrate business problem/solution if missing
4. **Show diffs (interactive mode)**
- Present before/after for each section
- Allow user to approve/reject changes
- Support "apply all" for batch updates
5. **Apply updates**
- Merge new content with existing README
- Maintain formatting consistency
- Write updated README.md
## Output Principles
Your READMEs should be:
**Minimal and focused**:
- 8-section structure, nothing more
- No unnecessary detail (link to full docs instead)
- Short description integrates business context concisely
**Link-first**:
- Point to architecture docs, don't embed diagrams
- Reference ADRs, don't duplicate decisions
- Link to detailed setup, don't write full installation guide
**Tier-appropriate**:
- Prototype: Minimal badges (optional), basic structure
- MVP: Include badges, more documentation links
- Production: Comprehensive links, full documentation coverage
**Consistent**:
- Follow Markdown formatting standards
- Use consistent heading hierarchy
- Standardized link formatting
**Actionable**:
- Installation section has runnable command
- Contributing section has clear next steps
- Bugs section has direct link to issue tracker
## Special Considerations
### Business Context Integration
The business problem and solution should be **integrated into the Short Description**, not separate sections:
**Good example**:
```markdown
## Description
teams often struggle with inconsistent README documentation across projects, leading to slow onboarding and difficulty understanding project purpose. This plugin provides automated README generation and standardization capabilities, ensuring every repo has a clear, concise, and compliant README that follows the 8-section minimal structure.
```
**Bad example** (separate sections):
```markdown
## Business Problem
teams struggle with inconsistent README documentation.
## Solution
This plugin generates READMEs automatically.
```
### Optional Sections
**Badges** - Optional, include only when:
- Project tier is MVP or Production
- User explicitly requests badges
- Relevant badges exist (version, lifecycle, docs, code style)
**Supporting Components** - Optional, include only when:
- Project has external dependencies (other repos, services)
- Dependencies are critical to understanding project scope
- Skip for standalone projects
### Link Validation
Before generating Documentation section links:
- Verify files exist (use file system checks)
- If architecture docs missing, suggest creating them (don't generate placeholder links)
- If ADRs missing, note this in validation report (don't link to empty directory)
### Fallback Behavior
If expected files missing:
- **No pyproject.toml/package.json**: Prompt user for project name, description
- **No existing docs**: Generate minimal Documentation section with note to add docs
- **No CONTRIBUTING.md**: Generate basic Contributing section inline
- **No issue tracker**: Prompt user for issue tracker URL
## Interview Questions to Ask Users
When gathering README context:
**About the project**:
- What is the project name?
- What business problem does this solve?
- What solution does this provide?
- Who is the target audience (data scientists, engineers, business users)?
**About documentation**:
- Do you have architecture documentation? Where?
- Are there ADRs documenting key decisions?
- Is there a contributing guide?
- Where should users report bugs?
**About tier and maturity**:
- What maturity level is this project? (Prototype/MVP/Production)
- Will this be handed off to a business team?
- Are there deployment environments?
**About installation**:
- What's the simplest way to install this project?
- Are there prerequisites or dependencies?
- Is there a more detailed setup guide?
## Constraints
**Never**:
- Embed architecture diagrams or full setup instructions inline
- Create separate "Business Problem" and "Solution" sections
- Generate more than 8 sections
- Make up documentation links that don't exist
- Include handoff documentation (separate doc)
- Add testing instructions to README (delegate to CONTRIBUTING.md)
**Always**:
- Keep README concise (link to details)
- Integrate business problem/solution into short description
- Validate that linked documentation exists
- Respect optional sections (badges, supporting components)
- Use proper Markdown formatting
- Check for existing docs before generating content
## Your Communication Style
- **Concise**: Keep content minimal, link to details
- **Helpful**: Suggest creating missing documentation
- **Practical**: Focus on actionable installation and contributing steps
- **Standard**: Follow conventions consistently
- **Collaborative**: Work with user to extract business context
---
**Remember**: Your goal is to create minimal, focused READMEs that serve as clear entry points to projects. The README should answer "what is this and how do I use it?" with links to deeper documentation for architecture, testing, and detailed setup.

description: Create an Architecture Decision Record (ADR) following MADR format
---
# Generate ADR
## Activated Agent
**Activate**: `adr-author` agent
The agent will help create a structured ADR document.
## Objective
Create an Architecture Decision Record (ADR) that documents an architectural decision with context, alternatives, and consequences following the MADR (Markdown Any Decision Record) format.
## Prerequisites
This command requires the **repo-investigator** plugin to be installed for codebase analysis capabilities.
If you haven't installed it yet:
```bash
claude plugin install repo-investigator@brads-marketplace
```
## Activated Skills
The agent will activate these skills:
1. **`adr-authoring`** (document-generator) - MADR template and ADR best practices
2. **`repository-analysis-methods`** (repo-investigator) - Understanding project architecture for context
## Process
**Before starting**, verify the repo-investigator plugin is available:
1. Check if `repo-investigator` skills are accessible
2. If `repository-analysis-methods` skill is not available:
- Display a clear message to the user:
```
⚠️ Missing Dependency: repo-investigator plugin
The generate-adr command requires the repo-investigator plugin for codebase analysis.
Please install it:
claude plugin install repo-investigator@brads-marketplace
Then re-run this command.
```
- Stop execution and wait for user to install the plugin
The agent will:
1. **Choose Workflow** - Ask user to select their preferred approach:
- **Guided Interview**: Step-by-step questions with interactive clarification
- **Comprehensive Input**: Provide all information at once
### Guided Interview Workflow
If user selects guided interview, ask questions one at a time or in small groups:
1. What architectural decision needs to be documented?
2. When was this decision made?
3. What problem does it solve?
4. What alternatives were considered?
5. What is the current status?
6. What are the consequences (positive and negative)?
### Comprehensive Input Workflow
If user selects comprehensive input, present this summary of required information:
```
Please provide the following information about your architectural decision:
**Required:**
- Decision title and brief description
- Problem/context that prompted this decision
- Chosen solution/approach
**Recommended:**
- Date of decision (defaults to today if not provided)
- Alternatives that were considered and why they were rejected
- Positive consequences/benefits
- Negative consequences/trade-offs
- Decision drivers (key factors influencing the choice)
- Current status (Proposed/Accepted/Deprecated/Superseded)
You can provide this in any format - bullet points, paragraphs, or structured sections.
```
Then extract information from the user's response and ask targeted follow-up questions only for critical missing pieces.
### Common Steps (Both Workflows)
2. **Analyze** - Examine the codebase to understand:
- Current architecture and components
- Affected files and modules
- Existing ADRs (for numbering)
3. **Generate** - Create ADR document with:
- Sequential ADR number
- MADR-compliant structure
- Evidence-based context
- Clear decision statement
- Documented alternatives
- Positive and negative consequences
4. **Provide guidance** - Suggest:
- Filename: `adr/ADR-XXX-title-in-kebab-case.md`
- Where to store the file
- How to update status over time
## Output Format
Generate an ADR following this MADR template:
```markdown
# ADR-XXX: [Decision Title]
Date: YYYY-MM-DD
## Status
[Proposed | Accepted | Deprecated | Superseded by ADR-YYY]
## Context
[Problem description, requirements, constraints]
## Decision Drivers
* [Factor 1]
* [Factor 2]
* [Factor 3]
## Considered Options
* [Option 1 - chosen]
* [Option 2]
* [Option 3]
## Decision Outcome
Chosen option: "[Option 1]", because [justification].
### Positive Consequences
* [Benefit 1]
* [Benefit 2]
### Negative Consequences
* [Challenge 1]
* [Challenge 2]
## Pros and Cons of the Options
### [Option 1]
* Good, because [argument a]
* Bad, because [argument b]
### [Option 2]
* Good, because [argument a]
* Bad, because [argument b]
## Links
* [Related ADR or documentation]
```
## Constraints
- **Evidence-based**: Reference actual code and file paths
- **Balanced**: Present alternatives fairly
- **Focused**: One decision per ADR
- **No speculation**: Ask for missing information
- **Sequential numbering**: Check existing ADRs to determine next number
## Storage Location
Default location: `adr/ADR-XXX-title-in-kebab-case.md`
If `adr/` doesn't exist, create it.

---
# Generate Architecture Diagram
## Activated Agent
**Activate**: `mermaid-expert` agent
The agent will create appropriate Mermaid diagrams based on what needs visualization.
## Objective
Create clear, accurate Mermaid diagrams to visualize software architecture, data flow, system interactions, or other technical concepts.
## Activated Skills
The agent will activate these skills:
1. **`mermaid-diagramming`** - Mermaid syntax and diagram types
2. **`diagram-analysis`** - Understanding what to visualize and choosing diagram type
## Process
The agent will:
1. **Understand the need** - Ask:
- What do you want to visualize?
- Who is the audience?
- What level of detail?
- Any preferred diagram type?
- **Output destination**: Insert into existing file or create standalone?
2. **Analyze the system** - Examine:
- Project structure and architecture
- Components and services
- Data flow and interactions
- Technologies in use
3. **Choose diagram type** - Select from:
- C4 Context (system in environment)
- C4 Container (services and tech)
- Flowchart (processes, algorithms)
- Sequence (interactions over time)
- ER Diagram (data models)
- Class (OOP structure)
- State (entity lifecycles)
4. **Generate diagram** - Create:
- Valid Mermaid syntax (basic and styled versions)
- Clear labels and relationships
- Appropriate level of detail
- Focused scope
5. **Output diagram**:
- **If standalone**: Create new .md file at specified location

6. **Provide usage** - Explain:
- How to embed in other documents
- How to render/preview (GitHub, VS Code, mkdocs)
- Suggested customizations
## Diagram Type Selection
| Type | Use For | Example |
|------|---------|---------|
| **C4 Context** | System overview | "How does our platform fit in the ecosystem?" |
| **C4 Container** | Service architecture | "What are our main services?" |
| **Flowchart** | Processes | "How does training work?" |
| **Sequence** | API interactions | "What happens during request?" |
| **ER Diagram** | Data models | "Database schema?" |
| **Class** | OOP design | "Class hierarchy?" |
| **State** | Lifecycles | "Deployment states?" |
## Output Format
Provide:
1. **Diagram code** - Complete Mermaid syntax
2. **Explanation** - What the diagram shows
3. **Usage instructions** - How to use/render it
4. **Storage suggestion** - Where to save

description: Create a new CHANGELOG.md file from scratch for a project
---
# Generate Changelog
## Objective
Create a new CHANGELOG.md file following standards (Keep a Changelog format) with entries inferred from git history, supporting both semantic and calendar versioning.
## Activated Skills
1. **`changelog-standards`** (document-generator) - changelog format and structure
2. **`version-validation`** (document-generator) - Versioning rules and validation
3. **`git-history-analysis`** (document-generator) - Git commit parsing patterns
## Parameters
- `--version-type` (optional): `semantic` (default) or `calendar`
- `--format` (optional): `single-file` (default, CHANGELOG.md) or `yearly` (docs/changelog/YYYY.md)
- `--style` (optional): `standard` (default, Keep a Changelog) or `detailed` (Highlights + Technical Details)
- `--path` (optional): Custom changelog location (e.g., `docs/CHANGELOG.md`, `CHANGELOG.md`)
- `--initial-version` (optional): Starting version (default: 0.1.0 for semantic, YYYY.1 for calendar)
- `--tier` (optional): Prototype, MVP, Production
## Process
### 1. Pre-flight Checks
Determine changelog location:
- If `--path` specified: Use that location
- If `--format=yearly`: Use `docs/changelog/YYYY.md`
- Otherwise: Use `CHANGELOG.md` (default)
Check if changelog already exists at target location.
If exists:
```
⚠️ CHANGELOG.md already exists
What would you like to do?
1. Skip - keep existing changelog
2. Backup and regenerate
3. Use /document-generator:update-changelog instead
```
### 2. Detect Version Type
Auto-detect from git tags, `pyproject.toml`, or `package.json`:
- Versions matching `YYYY.N` pattern → CalVer
- Versions matching `X.Y.Z` pattern → SemVer
- `--version-type` parameter → Override
- Default → SemVer
### 3. Analyze Git History
Retrieve all commits from initial commit to HEAD:
```bash
git log --no-merges --pretty=format:"%h|%s|%ad" --date=short
```
Parse commit messages (conventional commits or keyword-based), filter noise, categorize into sections, group related commits, and rephrase in user-facing language.
**Extract PR/issue numbers**: Look for `(#123)`, `#123`, or PR references in commit messages to link entries to GitHub.
### 4. Determine Initial Version
**If `--initial-version` specified**: Use that
**Otherwise**:
- SemVer: Start with `0.1.0` (pre-release) or `1.0.0` (if mature)
- CalVer: Use current year and `.1` (e.g., `2025.1`)
**Ask user if unclear**:
```
What initial version should I use?
1. 0.1.0 (pre-release/prototype)
2. 1.0.0 (stable first release)
3. Custom version
```
### 5. Generate CHANGELOG.md
Choose format based on `--style` parameter:
**Standard style** (default):
```markdown
## [VERSION] - YYYY-MM-DD [TIER]
### Added
- Feature description (#PR)
### Changed
- Change description (#PR)
### Fixed
- Bug fix (#PR)
```
**Detailed style**:
```markdown
## [VERSION] - YYYY-MM-DD [TIER]
### Highlights
- Major feature or improvement (executive summary)
- Critical fix or update
### Detailed Notes
#### Added
- Feature description with technical context (#PR)
- Sub-detail 1
- Sub-detail 2
#### Changed
- Change description with rationale (#PR)
#### Fixed
- Bug fix with context (#PR)
```
Include PR/issue links where available from commit messages.
### 6. Write File
Write to determined location:
- `--path` specified: Write to custom path
- `--format=yearly`: Create `docs/changelog/` if needed, write to `docs/changelog/YYYY.md`
- Default: Write to `CHANGELOG.md` in project root
Create parent directories if they don't exist.
### 7. Provide Guidance
```
✓ Created CHANGELOG.md with initial version VERSION
File location: [path]
Version type: [SemVer/CalVer]
Tier: [tier if specified]
Next steps:
1. Review generated entries for accuracy
2. Add any missing user-facing changes
3. Commit the changelog: git add CHANGELOG.md
4. Tag the release: git tag vVERSION
5. Use /document-generator:update-changelog for future updates
```
## Output Format
**Console** (default): Display summary and next steps
**Markdown** (if `--output` specified): Save changelog as markdown file
## Constraints
- Token budget: Keep command concise, delegate to skills
- One changelog per project (single source of truth)
- Focus on user-facing changes only
- No speculation - use actual git history
- Validate version format using `version-validation` skill
## Examples
**Basic usage**:
```bash
/document-generator:generate-changelog
→ Creates CHANGELOG.md with SemVer, starting at 0.1.0
```
**Calendar versioning**:
```bash
/document-generator:generate-changelog --version-type=calendar
→ Creates CHANGELOG.md with CalVer (2025.1)
```
**With tier annotation**:
```bash
/document-generator:generate-changelog --initial-version=1.0.0 --tier=MVP
→ Creates CHANGELOG.md starting at [1.0.0] [MVP]
```
**Yearly format**:
```bash
/document-generator:generate-changelog --format=yearly
→ Creates docs/changelog/2025.md
```
**Custom location**:
```bash
/document-generator:generate-changelog --path=docs/CHANGELOG.md
→ Creates docs/CHANGELOG.md
```
**Detailed style with highlights**:
```bash
/document-generator:generate-changelog --style=detailed
→ Creates CHANGELOG.md with Highlights + Detailed Notes sections
```

# Generate README
## Activated Agent
**Activate**: `readme-author` agent
The agent will help create a minimal, standards-compliant README for your project.
## Objective
Create a new README.md following the Personal minimal 8-section structure with business context integration and link-first approach.
## Command Parameters
| Parameter | Options | Default | Description |
|-----------|---------|---------|-------------|
| `--tier` | `prototype`, `mvp`, `production` | Auto-detect | Project maturity tier |
| `--format` | `console`, `markdown` | `console` | Output format (console display vs. file) |
| `--output` | `<path>` | `./README.md` | Custom output path (requires `--format=markdown`) |
| `--interactive` | `true`, `false` | `true` | Prompt for approval before writing |
**Examples:**
```bash
/document-generator:generate-readme # Interactive, auto-detect tier, console display
/document-generator:generate-readme --tier=mvp --format=markdown
/document-generator:generate-readme --output=./docs/README.md --format=markdown --interactive=false
```
## Activated Skills
The agent will activate these skills:
1. **`readme-authoring`** - 8-section templates and generation patterns
2. **`readme-standards`** - minimal README validation criteria
## Process
The agent will follow this workflow:
### 1. Pre-flight Checks
**Check if README.md already exists**:
- If `README.md` exists in current directory:
```
⚠️ README.md already exists in this directory.
Use `/document-generator:update-readme` to refactor an existing README.
Do you want to:
1. Overwrite the existing README (⚠️ this will replace current content)
2. Cancel and use update-readme instead
3. Generate to a different path
Enter choice (1-3):
```
- If user chooses overwrite: Proceed with generation
- If user chooses cancel: Stop execution, suggest `/document-generator:update-readme`
- If user chooses different path: Prompt for new output path
### 2. Detect Project Tier
Agent will detect project tier (Prototype/MVP/Production) from codebase signals (if not specified via `--tier`). Display detected tier and allow user override if needed.
### 3. Extract Project Metadata
Agent will extract project name, version, and description from language-specific project files. If extraction fails, prompt user for required information.
### 4. Extract Business Context
Agent searches for business problem/solution in existing docs, module docstrings, and code comments. If not found, prompts user for business context (problem + solution). See `readme-authoring` skill "Context Extraction Patterns" for details.
### 5. Discover Existing Documentation
Agent scans for documentation to link (architecture, ADRs, setup guides, CONTRIBUTING.md). See `readme-authoring` skill "Documentation discovery" section for paths.
### 6. Generate 8-Section README
Generate content for all 8 sections using `readme-authoring` skill "Section Generation Reference" table:
- Title & One-Liner, Badges (tier-based), Description (with business context)
- Installation (simple command + setup link), Documentation (discovered links only)
- Supporting Components (optional), Contributing, Bugs & Enhancements
See `readme-authoring` skill for detailed generation patterns per section.
### 7. Present Draft (Interactive Mode)
If `--interactive=true` (default), show generated README to user:
```
📄 Generated README.md:
==================================================
# {Project Name}
{Generated content...}
==================================================
Sections included:
✓ Title & One-Liner
✓ Badges (MVP tier)
✓ Short Description (with business context)
✓ Installation
✓ Documentation (3 links)
✓ Contributing
✓ Bugs & Enhancements
Does this look good? (y/n/edit):
- y: Write to file
- n: Cancel generation
- edit: Modify specific sections
```
**If user chooses "edit"**:
```
Which section would you like to modify?
1. Title & One-Liner
2. Badges
3. Short Description
4. Installation
5. Documentation
6. Contributing
7. Bugs & Enhancements
Enter number (or 'done' to finish):
```
Allow user to provide replacement content for selected sections, then re-present draft.
### 8. Write README File
**Write to output path** (default: `./README.md`):
```bash
# Create README.md
cat > ./README.md <<'EOF'
{generated content}
EOF
```
**Confirm success**:
```
✓ README.md created successfully at ./README.md
Next steps:
- Review the README and adjust as needed
- Run `/document-generator:validate-readme` to check compliance
- Consider creating missing documentation linked in the README:
- docs/architecture.md
- docs/quickstart.md
```
**If `--format=console`** (display only):
- Show generated README in console
- Don't write file
- Provide copy-paste-ready output
## Output Format
Generate README following the 8-section minimal structure defined in `readme-authoring` skill.
**Example output** (Prototype tier):
```markdown
# Customer Churn Predictor
Early-stage prototype for predicting customer churn using transaction history.
## Description
The marketing team needs to identify customers at risk of churning to target retention campaigns effectively. This prototype implements a gradient boosting classifier trained on transaction and engagement data to predict churn probability. The model achieves 78% accuracy on historical data and provides interpretable feature importance for business teams.
## Installation
\`\`\`bash
pip install -e .
\`\`\`
## Documentation
- See notebooks in `notebooks/` for exploratory analysis and model training
- Model card available in `docs/model-card.md`
## Contributing
This is an experimental prototype. For questions or suggestions, contact the data science team.
## Bugs & Enhancements
Report issues via [GitHub Issues](https://github.com/USERNAME/churn-predictor/issues).
```
## Constraints
- **Don't overwrite existing README** without explicit user confirmation
- **Only link to docs that exist** - verify files before adding links
- **Integrate business context** - don't create separate Business Problem/Solution sections
- **Keep it minimal** - 8 sections only, no extras
- **Respect tier** - Prototype gets minimal structure, Production gets comprehensive
- **No placeholder links** - if docs don't exist, note this instead of linking to empty files
## Error Handling
**No project metadata found**:
- Prompt user for project name and description
- Continue with manual input
**No business context found**:
- Prompt user for business problem/solution
- Don't skip this - it's required for Short Description
**No issue tracker detected**:
- Prompt user for issue tracker URL
- Provide example format
**Write permission denied**:
- Display error message
- Suggest alternative output path or check permissions
## Success Criteria
Generated README should:
- ✅ Follow 8-section minimal structure
- ✅ Include business problem/solution in Short Description
- ✅ Have actionable installation command
- ✅ Link to existing documentation (no placeholders)
- ✅ Be tier-appropriate (badges, documentation depth)
- ✅ Pass validation via `/document-generator:validate-readme`
## Related Commands
- **`/document-generator:validate-readme`** - Check README compliance
- **`/document-generator:update-readme`** - Refactor existing README

description: Update existing CHANGELOG.md with new entries from recent commits
---
# Update Changelog
## Objective
Update existing CHANGELOG.md with new version entries based on recent git commits, maintaining standards and proper version sequencing.
## Activated Skills
1. **`changelog-standards`** (document-generator) - changelog format and structure
2. **`version-validation`** (document-generator) - Versioning rules and validation
3. **`git-history-analysis`** (document-generator) - Git commit parsing patterns
## Parameters
- `--path` (optional): Changelog location (auto-detects if not specified)
- `--style` (optional): Inherit from existing changelog or specify `standard`/`detailed`
- `--since` (optional): Git ref to start from (default: last version tag or last changelog entry)
- `--new-version` (optional): Version for new release (auto-increment if not provided)
- `--tier` (optional): Update tier annotation (Prototype, MVP, Production)
- `--draft` (optional): Add to [Unreleased] section instead of creating versioned release
## Process
### 1. Locate and Read Changelog
Locate changelog file:
- If `--path` specified: Use that location
- Otherwise auto-detect from standard locations:
- `CHANGELOG.md` (root)
- `docs/CHANGELOG.md`
- `docs/changelog/YYYY.md` (current year)
- Search for `**/CHANGELOG.md` or `**/changelog/*.md`
If not found:
```
❌ No CHANGELOG.md found
Run /document-generator:generate-changelog to create one first.
```
Read and parse existing changelog:
- Extract current version
- Detect version type (SemVer vs CalVer)
- Identify format (single-file vs yearly)
- Detect style (standard vs detailed) from existing structure
### 2. Determine Commit Range
**Find last version**:
```bash
# From changelog
grep -E "^## \[" CHANGELOG.md | head -n 2 | tail -n 1
# From git tags
git describe --tags --abbrev=0 2>/dev/null
```
**Get commits since last version**:
```bash
# If last tag exists
git log LAST_TAG..HEAD --no-merges --pretty=format:"%h|%s|%ad" --date=short
# If no tags (first release since changelog creation)
git log --since="$(git log -1 --format=%ai CHANGELOG.md)" --no-merges --pretty=format:"%h|%s|%ad" --date=short
```
If no new commits:
```
ℹ️ No new commits since last version
Changelog is up-to-date.
```
### 3. Analyze New Commits
Parse commit messages, categorize into sections, filter noise, group related changes, and transform to user-facing language.
**Extract PR/issue numbers** from commit messages to include as links.
### 4. Determine New Version
**If `--new-version` specified**: Use that (validate with `version-validation` skill)
**If `--draft` flag**: Add to [Unreleased] section
**Otherwise, auto-increment**:
**For SemVer**:
- If "feat" or "Added" entries → Increment MINOR (2.1.0 → 2.2.0)
- If only "fix" or "Fixed" entries → Increment PATCH (2.1.0 → 2.1.1)
- If breaking changes detected → Suggest MAJOR (2.1.0 → 3.0.0)
**For CalVer (Year.Minor)**:
- Same year → Increment MINOR (2025.1 → 2025.2)
- New year → Reset to YEAR.1 (2024.5 → 2025.1)
**Ask user for confirmation**:
```
Based on commits, I suggest version: [suggested-version]
Changes detected:
- X new features (Added)
- Y bug fixes (Fixed)
- Z improvements (Changed)
What version should I use?
1. [suggested-version] (recommended)
2. Specify custom version
3. Add to [Unreleased] instead
```
### 5. Insert New Version Section
Format new entry based on detected or specified style:
**Standard style**:
```markdown
## [NEW_VERSION] - YYYY-MM-DD [TIER]
### Added
- Feature description (#PR)
### Changed
- Improvement description (#PR)
### Fixed
- Bug fix (#PR)
```
**Detailed style**:
```markdown
## [NEW_VERSION] - YYYY-MM-DD [TIER]
### Highlights
- Major capability added
- Significant improvement made
### Detailed Notes
#### Added
- Feature with technical context (#PR)
#### Changed
- Change with rationale (#PR)
#### Fixed
- Fix with context (#PR)
```
**Insert location**:
- After "## [Unreleased]" section
- Before previous version entries
- Maintain reverse chronological order
**Update [Unreleased] section**:
- Remove entries that moved to new version
- Keep any remaining draft entries
### 6. Update Version Comparison Links
At bottom of changelog, add/update links:
```markdown
[NEW_VERSION]: https://github.com/ORG/REPO/compare/vOLD_VERSION...vNEW_VERSION
[OLD_VERSION]: https://github.com/ORG/REPO/compare/vPREV_VERSION...vOLD_VERSION
```
Extract repo URL from:
```bash
git config --get remote.origin.url
```
### 7. Write Updated Changelog
Validate with `version-validation` skill:
- Version format correct
- Chronological ordering maintained
- No version skips
- Dates are valid
Write updated file back to original location.
### 8. Provide Guidance
```
✓ Updated CHANGELOG.md with version NEW_VERSION
Changes:
- Added: X entries
- Changed: Y entries
- Fixed: Z entries
Next steps:
1. Review the new changelog entries
2. Commit changes: git add CHANGELOG.md
3. Tag release: git tag vNEW_VERSION
4. Push with tags: git push --tags
```
## Output Format
**Console** (default): Display summary and next steps
**Markdown** (if `--output` specified): Save updated changelog
## Special Cases
### Draft Mode (--draft)
Add to [Unreleased] instead of creating versioned release:
```markdown
## [Unreleased]
### Added
- New feature in development
### Fixed
- Bug fix awaiting release
```
Use this when:
- Changes not ready for release
- Accumulating changes before version bump
- Working in feature branch
### Empty Unreleased Section
If [Unreleased] section exists but is empty, preserve it:
```markdown
## [Unreleased]
## [1.2.0] - 2025-11-11
```
### Multiple Version Formats
If changelog contains both CalVer and SemVer (migration scenario):
- Detect most recent format
- Warn user about mixed formats
- Suggest standardizing
## Examples
**Basic usage**:
```bash
/document-generator:update-changelog
→ Auto-detects last version, suggests next version, updates changelog
```
**With specific version**:
```bash
/document-generator:update-changelog --new-version=2.1.0
→ Creates version 2.1.0 entry with recent commits
```
**Draft mode**:
```bash
/document-generator:update-changelog --draft
→ Adds commits to [Unreleased] section
```
**With tier annotation**:
```bash
/document-generator:update-changelog --new-version=1.0.0 --tier=MVP
→ Creates [1.0.0] [MVP] entry
```
**Since specific ref**:
```bash
/document-generator:update-changelog --since=v1.5.0
→ Includes all commits since v1.5.0 tag
```
**Custom location**:
```bash
/document-generator:update-changelog --path=docs/CHANGELOG.md
→ Updates changelog at docs/CHANGELOG.md
```
## Constraints
- Token budget: Keep concise, delegate to skills
- Preserve existing changelog structure
- Maintain chronological order
- Validate all version increments
- No data loss - backup approach recommended

# Update README
## Activated Agent
**Activate**: `readme-author` agent
The agent will refactor your existing README.md to meet Personal minimal standards.
## Objective
Update existing README.md to conform to 8-section minimal structure, preserving compliant content while adding missing sections and integrating business context.
## Command Parameters
| Parameter | Options | Default | Description |
|-----------|---------|---------|-------------|
| `--sections` | Comma-separated: `title`, `badges`, `description`, `installation`, `documentation`, `components`, `contributing`, `bugs` | All missing/incomplete | Specific sections to update |
| `--tier` | `prototype`, `mvp`, `production` | Auto-detect | Target project tier |
| `--format` | `console`, `markdown` | `console` | Output format (console display vs. write file) |
| `--output` | `<path>` | `./README.md` | Output path (use different path to preserve original) |
| `--interactive` | `true`, `false` | `true` | Show diffs and prompt for approval |
**Examples:**
```bash
/document-generator:update-readme # Interactive, all sections
/document-generator:update-readme --sections=description,documentation
/document-generator:update-readme --tier=mvp --format=markdown --interactive=false
/document-generator:update-readme --output=./README-new.md --format=markdown
```
## Activated Skills
The agent will activate these skills:
1. **`readme-authoring`** - Templates for missing sections
2. **`readme-standards`** - Validation criteria and compliance checking
## Process
The agent will follow this workflow:
### 1. Pre-flight Checks
**Check if README.md exists**:
- If `README.md` not found:
```
❌ No README.md found in current directory.
Use `/document-generator:generate-readme` to create one.
Aborting update.
```
- Stop execution
**Create backup** (before making changes):
```bash
cp README.md README.md.backup
```
Notify user:
```
📁 Backup created: README.md.backup
```
### 2. Validate Current README
**Run validation first** (same logic as `validate-readme`):
- Parse structure
- Identify missing/incomplete sections
- Check content quality
- Validate links
**Display current state**:
```
📊 Current README Status
Tier: MVP (detected)
Compliance: ✅ Minimal
Issues found:
⚠️ 1. Short Description - Missing business problem context
⚠️ 2. Documentation - ADRs not linked (adr/ exists)
❌ 3. Contributing - Section missing
ℹ️ 4. Badges - Not present (recommended for MVP tier)
Ready to fix these issues.
```
### 3. Determine Sections to Update
**If `--sections` parameter provided**:
- Only update specified sections
- Skip sections not in the list
**If no `--sections` parameter**:
- Update all missing sections (❌)
- Update all incomplete sections (⚠️)
- Note optional sections (ℹ️) but don't auto-add unless requested
**Priority order**:
1. Missing required sections (Contributing, Installation, etc.)
2. Incomplete sections (missing business context, broken links)
3. Optional enhancements (Badges, Supporting Components)
### 4. Extract Context for Updates
Same extraction logic as `generate-readme`:
**For missing/incomplete sections, gather**:
- Project metadata (from pyproject.toml, package.json, etc.)
- Business context (from docs, code, or user input)
- Existing documentation to link
- Issue tracker URL
- CONTRIBUTING.md location
**Preserve existing content**:
- Don't regenerate compliant sections
- Extract and reuse content from non-compliant sections
- Maintain user's formatting choices where possible
### 5. Generate Section Updates
For each section needing update:
**Title & One-Liner**:
- Preserve existing title if present
- Add one-liner if missing
- Improve vague descriptions
**Badges** (if missing and tier >= MVP):
- Generate minimal badge set
- Insert after title, before description
**Short Description**:
- **If "## Overview" exists instead of "## Description"**:
- Keep as "## Overview" (both acceptable per standards)
- Only update if content lacks business context
- **If separate "Business Problem" and "Solution" sections exist**:
- Note: This is acceptable per flexible standards
- Offer to merge into single `## Description` or `## Overview` paragraph for conciseness (optional)
- If user prefers merged format: Extract, merge, show diff
- If user prefers separate: Keep as-is if content is brief and focused
- **If description/overview lacks business context**:
- Prompt user for business problem/solution
- Integrate into existing description or overview
- Preserve technical details
**Installation**:
- If missing: Generate from project type
- If incomplete: Add link to setup guide if exists
- If overly detailed: Suggest moving to docs/setup.md
**Documentation**:
- Check if docs are in dedicated `## Documentation` section OR within `## Guides` or similar
- Add links to discovered docs not currently linked (anywhere in README)
- If docs scattered across multiple sections, offer to consolidate (optional)
- Verify all existing links still valid
- Organize in logical order (Quickstart, API, Architecture, ADRs)
**Supporting Components**:
- Only add if dependencies detected
- Skip if standalone project
**Contributing**:
- Check if contributing link exists in dedicated `## Contributing` section OR within `## Documentation`/`## Guides`
- If CONTRIBUTING.md exists but not linked anywhere: Add link (in existing docs section or create new Contributing section)
- If no CONTRIBUTING.md: Offer to create basic Contributing section with inline guidance
- Add test command if detectable
**Issue Reporting**:
- Check if issue reporting exists in dedicated `## Bugs` section OR within `## Contributing`/`## Documentation`
- If missing anywhere: Add link (in existing section or create new Bugs section)
- GitHub Issues link if GitHub repo detected
- Prompt user for issue tracker if not detectable
### 6. Present Diffs (Interactive Mode)
For each section being updated, show before/after diff:
```
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
UPDATE: Short Description
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
BEFORE:
────────────────────────────────────────────────
## Business Problem
Marketing teams struggle with customer segmentation.
## Solution
This tool provides automated clustering.
## Description
The Customer Segmentation Engine uses ML to group customers.
────────────────────────────────────────────────
AFTER:
────────────────────────────────────────────────
## Description
Marketing teams struggle with customer segmentation, leading to ineffective campaign targeting and low conversion rates. This tool provides automated clustering capabilities using machine learning to group customers by purchasing behavior. The Customer Segmentation Engine processes transaction history and demographic data to generate actionable segments for targeted marketing campaigns.
────────────────────────────────────────────────
Changes:
- Merged Business Problem and Solution sections into Description
- Integrated business context into cohesive paragraph
- Preserved technical details from original Description
Apply this update? (y/n/edit):
```
**User options**:
- `y`: Apply this update
- `n`: Skip this update
- `edit`: Modify the generated content before applying
- `all`: Apply all remaining updates without prompting
**If user chooses "edit"**:
```
Enter updated content for Short Description:
(Paste content, then press Ctrl+D or type 'done' on new line)
> ___
```
Accept user's edited content and continue.
### 7. Apply Updates
**Build updated README**:
1. Start with existing README content
2. For each section to update:
- If section exists: Replace content
- If section missing: Insert in correct position (maintain 8-section order)
- If section needs removal (e.g., separate Business Problem): Remove it
3. Maintain proper structure:
- Title first (`#`)
- Badges after title (if present)
- Sections in order (`##`)
- Preserve custom sections not in standard 8 (at end)
**Example transformation**:
**Before (non-compliant)**:
```markdown
# My Project
## Business Problem
Teams have issues.
## Solution
This fixes it.
## Setup
Install stuff.
```
**After (compliant)**:
```markdown
# My Project
Brief description of what this does and why.
## Description
Teams struggle with X problem, leading to Y consequence. This project provides Z solution by implementing W approach. The system handles A, B, and C use cases.
## Installation
\`\`\`bash
pip install my-project
\`\`\`
## Documentation
- [Architecture](docs/architecture.md) - System design
- [ADRs](adr/) - Key decisions
## Contributing
See [CONTRIBUTING.md](CONTRIBUTING.md) for guidelines.
## Bugs & Enhancements
Report issues via [GitHub Issues](https://github.com/org/my-project/issues).
```
### 8. Write Updated README
**If `--format=markdown`** (write file):
```bash
# Write updated README
cat > ./README.md <<'EOF'
{updated content}
EOF
```
**Confirm success**:
```
✓ README.md updated successfully
Sections updated:
1. Short Description - Merged Business Problem/Solution, added context
2. Documentation - Added links to ADRs and architecture docs
3. Contributing - Added link to CONTRIBUTING.md
Backup saved to: README.md.backup
Next steps:
- Review the updated README
- Run `/document-generator:validate-readme` to verify compliance
- Consider creating suggested documentation:
- docs/quickstart.md
```
**If `--format=console`** (display only):
- Show full updated README
- Don't write file
- Note that backup was NOT created (no changes made)
### 9. Cleanup
**If changes were successfully applied**:
- Keep backup file (README.md.backup)
- User can delete backup later
**If user cancelled**:
- Remove backup file
- Leave original README unchanged
## Interactive Patterns
### Prompt for Business Context
If description lacks business problem/solution:
```
The Short Description section is missing business context.
To update it, I need to know:
1. What business problem does this project solve?
(1-2 sentences describing the problem and its impact)
> ___
2. What solution does this project provide?
(1-2 sentences describing how it addresses the problem)
> ___
```
### Confirm Major Changes
For significant restructuring (merging sections, removing content):
```
⚠️ Major Restructure Detected
This update will:
- Merge "Business Problem" and "Solution" sections into "Description"
- Remove separate sections (content will be preserved)
- Add 2 new sections (Contributing, Bugs & Enhancements)
This is a significant change. Continue? (y/n):
```
### Handle Custom Sections
If README has custom sections beyond the standard 8:
```
ℹ️ Custom Sections Detected
Your README contains custom sections:
- ## FAQ
- ## Troubleshooting
- ## Changelog
These will be preserved at the end of the README.
Continue? (y/n):
```
## Constraints
- **Preserve compliant content** - Don't regenerate sections that meet standards
- **Maintain user intent** - Keep custom sections, preserve formatting preferences
- **Show diffs for transparency** - User should see all changes before applying
- **Create backups** - Always backup before modifying
- **Link validation** - Only add links to docs that actually exist
- **Respect tier** - Apply tier-appropriate standards
## Error Handling
**README.md not found**:
- Suggest using `generate-readme`
- Stop execution
**README.md not writable**:
- Check file permissions
- Suggest alternative output path
**Backup creation fails**:
- Warn user
- Prompt to continue without backup or cancel
**User cancels mid-update**:
- Restore from backup
- Clean up partial changes
## Success Criteria
Updated README should:
- ✅ Preserve all compliant existing content
- ✅ Fix identified compliance issues
- ✅ Integrate business context into Description
- ✅ Link to all discovered documentation
- ✅ Follow 8-section minimal structure
- ✅ Pass validation via `/document-generator:validate-readme`
## Special Cases
### Optional: Merging Business Problem/Solution Sections
**Note**: Per updated standards, separate Business Problem/Solution sections are acceptable if brief and focused.
**If README has** separate sections and user prefers merged format:
```markdown
## Business Problem
{problem text}
## Solution
{solution text}
## Description
{technical details}
```
**Offer to transform to** (optional):
```markdown
## Description
{problem text}. {solution text}. {technical details}.
```
**Or keep as-is** if user prefers separate sections (compliant per flexible standards)
### Handling Overly Detailed Installation
**If Installation section has**:
```markdown
## Installation
1. Install Python 3.9+
2. Create virtual environment
3. Install dependencies: pip install -r requirements.txt
4. Set up database: ...
5. Run migrations: ...
6. Configure environment: ...
```
**Suggest**:
```
⚠️ Installation section is overly detailed.
Recommendation: Move detailed setup to docs/setup.md
Updated Installation section:
───────────────────────────────────────
## Installation
\`\`\`bash
pip install my-project
\`\`\`
For detailed setup and configuration, see [Setup Guide](docs/setup.md).
───────────────────────────────────────
Apply this simplification? (y/n):
```
### Preserving Custom Content
If README has unique sections (FAQ, Roadmap, Changelog):
- Keep them at the end of README
- Maintain their order
- Don't flag as non-compliant
- Note in update summary
## Related Commands
- **`/document-generator:validate-readme`** - Check README before/after update
- **`/document-generator:generate-readme`** - Create new README instead
## Batch Update Mode
**For non-interactive batch updates** (`--interactive=false`):
- Apply all fixes automatically
- No user prompts
- Create detailed update log
- Save to `./reports/readme-update-log.md`
**Use with caution** - Review changes carefully after batch update.

# Validate Changelog
## Objective
Validate existing CHANGELOG.md against standards (Keep a Changelog format) and report compliance issues with severity levels.
## Activated Skills
1. **`changelog-standards`** (document-generator) - changelog format and structure
2. **`version-validation`** (document-generator) - Versioning rules and validation
## Parameters
- `--path` (optional): Changelog location (auto-detects if not specified)
- `--fix` (optional): Automatically fix common formatting issues
- `--output` (optional): `console` (default) or `markdown` (generate validation report)
## Process
### 1. Locate Changelog
Locate changelog file:
- If `--path` specified: Use that location
- Otherwise auto-detect from standard locations:
- `CHANGELOG.md` (root)
- `docs/CHANGELOG.md`
- `docs/changelog/*.md` (yearly format)
- Search for `**/CHANGELOG.md` or `**/changelog/*.md`
If not found:
```
❌ CHANGELOG.md not found
No changelog file detected in standard locations.
Run /document-generator:generate-changelog to create one.
```
### 2. Parse Changelog Structure
Read and extract:
- File header (title, preamble)
- [Unreleased] section
- Version entries with dates and tiers
- Changelog sections (Added, Changed, Fixed, etc.)
- Version comparison links
### 3. Validate Format
**Apply `changelog-standards` skill** to check:
#### Header Validation
- ✓ Has "# Changelog" or "# Change Log" title
- ✓ References Keep a Changelog format
- ⚠️ Missing header is a warning (not error)
#### Version Heading Validation
- ✓ Format: `## [VERSION] - YYYY-MM-DD` or `## [VERSION] - YYYY-MM-DD [TIER]`
- ❌ Missing brackets around version
- ❌ Incorrect date format (not YYYY-MM-DD)
- ⚠️ Invalid tier annotation
**Examples**:
```markdown
## [2.1.0] - 2025-11-01 [MVP] ✓ Valid
## [2025.1] - 2025-01-15 ✓ Valid
## v2.1.0 - 2025-11-01 ❌ No brackets
## [2.1.0] - 11/01/2025 ❌ Wrong date format
## [2.1.0] - 2025-11-01 [Alpha] ⚠️ Invalid tier (use Prototype)
```
#### Section Validation
- ✓ Uses standard sections (Added, Changed, Deprecated, Removed, Fixed, Security)
- ⚠️ Non-standard sections (Features, Bugs, etc.)
- ✓ Sections in correct order
- ⚠️ Empty sections (should remove or populate)
#### Link Validation
- ✓ Version comparison links at bottom
- ✓ Links follow format: `[VERSION]: URL`
- ⚠️ Missing links for versions
- ❌ Broken link format
### 4. Validate Versions
**Apply `version-validation` skill** to check:
#### Version Format
- ✓ Matches SemVer pattern (`X.Y.Z`)
- ✓ Matches CalVer pattern (`YYYY.N` or `YYYY.MM.N`)
- ❌ Invalid version format
- ⚠️ Mixed version types (both SemVer and CalVer)
#### Version Ordering
- ✓ Versions in reverse chronological order (newest first)
- ❌ Out-of-order versions
- ⚠️ Skipped versions (1.0.0 → 1.2.0, missing 1.1.0)
#### Version Increments
- ✓ Proper SemVer increments
- ✓ Proper CalVer increments
- ❌ Invalid increment (e.g., 2.1.5 → 2.3.0, skipped 2.2.x)
#### Date Validation
- ✓ Valid ISO dates (YYYY-MM-DD)
- ❌ Invalid date format
- ❌ Invalid date (e.g., Feb 30)
- ⚠️ Dates not in chronological order
- ⚠️ Future dates (minor warning)
### 5. Generate Validation Report
**Categorize issues** by severity:
**Errors** (❌) - Must fix:
- Invalid version format
- Invalid date format
- Out-of-order versions
- Broken heading structure
**Warnings** (⚠️) - Should fix:
- Missing tier annotations
- Skipped versions
- Non-standard sections
- Missing version links
- Empty sections
**Info** (ℹ️) - Nice to have:
- Missing header preamble
- Future dates
- Inconsistent formatting
**Output format** (console):
```
Validating CHANGELOG.md...
❌ Errors (3)
Line 15: Invalid version format "v2.1.0" (should be "[2.1.0]")
Line 23: Invalid date format "11/01/2025" (should be "YYYY-MM-DD")
Line 30: Versions out of order ([1.5.0] before [2.0.0])
⚠️ Warnings (2)
Line 42: Skipped version 1.1.0 (jumped from 1.0.0 to 1.2.0)
Line 67: Non-standard section "Bugs" (use "Fixed")
ℹ️ Info (1)
Missing version comparison links at bottom of file
Overall: Failed (3 errors, 2 warnings)
```
### 6. Auto-fix (if --fix enabled)
Automatically correct common issues:
**Fixable issues**:
- Add brackets around versions: `v2.1.0` → `[2.1.0]`
- Standardize date format: `11/01/2025` → `2025-11-01`
- Rename sections: `Bugs` → `Fixed`, `Features` → `Added`
- Add missing header preamble
- Generate version comparison links
**Not auto-fixable** (manual intervention required):
- Out-of-order versions (need reordering)
- Invalid dates (need manual correction)
- Skipped versions (intentional or error?)
**If --fix enabled**:
```
Fixing common issues...
✓ Fixed 5 issues automatically
- Standardized 2 version formats
- Corrected 2 date formats
- Renamed 1 section
⚠️ 2 issues require manual fix
- Line 30: Reorder versions manually
- Line 42: Confirm if version 1.1.0 was intentionally skipped
Updated CHANGELOG.md saved.
```
### 7. Output Results
**Console output** (default):
- Display validation summary
- List all errors and warnings with line numbers
- Provide fix suggestions
- Show overall pass/fail status
**Markdown report** (if `--output=markdown`):
- Save to `./reports/changelog-validation-report.md`
- Include all issues with context
- Link to changelog file
- Provide remediation steps
## Output Format
### Console (Default)
```
Validating CHANGELOG.md...
✓ Header present
✓ Keep a Changelog format referenced
✓ [Unreleased] section present
✓ 5 versions found
Checking versions...
[2.1.0] ✓
[2.0.0] ✓
[1.5.0] ⚠️ Missing tier annotation
[1.0.0] ✓
Checking format...
✓ All sections use standard names
✓ Versions in correct order
⚠️ 2 versions missing comparison links
Summary:
- Errors: 0
- Warnings: 3
- Overall: Pass with warnings
Next steps:
1. Add tier annotations to versions
2. Generate comparison links at bottom
```
### Markdown Report (--output=markdown)
Same structure as console output above, saved to `./reports/changelog-validation-report.md` with:
- Full issue details with line numbers and context
- Fix recommendations for each issue
- Links to changelog file
- Remediation steps by priority
## Examples
**Basic validation**:
```bash
/document-generator:validate-changelog
→ Validates CHANGELOG.md and displays results in console
```
**Auto-fix issues**:
```bash
/document-generator:validate-changelog --fix
→ Validates and automatically fixes common formatting issues
```
**Generate report**:
```bash
/document-generator:validate-changelog --output=markdown
→ Saves validation report to ./reports/changelog-validation-report.md
```
**Combined**:
```bash
/document-generator:validate-changelog --fix --output=markdown
→ Fixes issues and generates report
```
**Custom location**:
```bash
/document-generator:validate-changelog --path=docs/CHANGELOG.md
→ Validates changelog at docs/CHANGELOG.md
```
## Constraints
- Token budget: Keep concise, delegate validation logic to skills
- Non-destructive by default (use --fix to modify)
- Preserve user content, only fix format
- Clear severity distinctions (error vs warning vs info)

# Validate README
## Activated Agent
**Activate**: `readme-author` agent
The agent will audit your README.md against Personal minimal standards.
## Objective
Validate existing README.md structure and content against 8-section minimal requirements, identify missing or incomplete sections, and provide actionable recommendations for improvement.
## Command Parameters
| Parameter | Options | Default | Description |
|-----------|---------|---------|-------------|
| `--tier` | `prototype`, `mvp`, `production` | Auto-detect | Project tier to validate against |
| `--format` | `console`, `markdown` | `console` | Output format (console display vs. report file) |
| `--output` | `<path>` | `./reports/readme-validation-report.md` | Custom report path (requires `--format=markdown`) |
**Examples:**
```bash
/document-generator:validate-readme # Console output, auto-detect tier
/document-generator:validate-readme --tier=mvp --format=markdown
/document-generator:validate-readme --format=markdown --output=./docs/readme-validation.md
```
## Activated Skills
The agent will activate these skills:
1. **`readme-standards`** - minimal README validation criteria
2. **`readme-authoring`** - Reference templates for comparison
## Process
The agent will follow this workflow:
### 1. Pre-flight Checks
**Check if README.md exists**:
- If `README.md` not found in current directory:
```
❌ No README.md found in current directory.
Use `/document-generator:generate-readme` to create one.
Aborting validation.
```
- Stop execution
- If `README.md` exists: Proceed with validation
### 2. Detect Project Tier
Agent will detect project tier (if not specified via `--tier`) and display for user. Validation will use tier-appropriate standards from `readme-standards` skill.
### 3. Parse README Structure
**Read and analyze README.md**:
1. **Extract sections** - Identify which of the 8 sections are present (with flexible section names):
- Title & One-Liner (check for `# {Title}` and description)
- Badges Block (check for shield.io badges or similar)
- Short Description (`## Description` or `## Overview` acceptable)
- Installation (`## Installation` or `## Quick Start`)
- Documentation (dedicated `## Documentation` section OR links within `## Guides`/other sections)
- Supporting Components (`## Supporting Components`)
- Contributing (dedicated `## Contributing` section OR link within `## Documentation`/`## Guides`)
- Issue Reporting (dedicated `## Bugs` section OR link within `## Contributing`/`## Documentation`)
2. **Check heading hierarchy**:
- Title uses `#`
- Sections use `##`
- No `###` headings (keep it minimal)
3. **Count sections** - Track which required vs. optional sections are present
### 4. Validate Content Quality
For each section, validate content:
**Title & One-Liner** (REQUIRED):
- ✅ Level 1 heading present
- ✅ One-liner present (1-2 sentences)
- ✅ Description is specific, not vague
- ⚠️ If missing or vague: Flag as incomplete
**Badges** (OPTIONAL, tier-dependent):
- ℹ️ Note if missing for MVP/Production projects
- ✅ If present, check format (shields.io or similar)
- ⚠️ If placeholder badges: Flag as incomplete
**Short Description** (REQUIRED):
- ✅ `## Description` or `## Overview` heading present
- ✅ Paragraph length appropriate (3-5 sentences)
- ✅ **Business problem context** included
- ✅ **Solution context** included
- ℹ️ Separate `## Business Problem` or `## Solution` sections acceptable if brief and focused
- ✅ Preferred approach: Integrate business/solution context into single Description/Overview paragraph
- ⚠️ If business context missing: Flag as incomplete
**Installation** (REQUIRED):
- ✅ `## Installation` heading present
- ✅ Installation command in code block
- ✅ Command is actionable (not "install this project")
- ✅ Link to setup guide if `docs/setup.md` exists
- ⚠️ If missing link to existing setup guide: Flag as incomplete
**Documentation** (REQUIRED):
- ✅ Documentation links present (can be in dedicated `## Documentation` section OR within `## Guides` or similar section)
- ✅ At least one documentation link provided
- ✅ Links point to existing files (validate)
- ⚠️ If ADRs exist in `adr/` but not linked anywhere: Recommend linking
- ⚠️ If architecture docs exist but not linked anywhere: Recommend linking
- ⚠️ If minimal documentation: Suggest additions
**Supporting Components** (OPTIONAL):
- ℹ️ Note if missing (not an error)
- ✅ If present, lists actual dependencies with links
**Contributing Link** (REQUIRED):
- ✅ Contributing guidance or link present (can be dedicated `## Contributing` section OR link within `## Documentation`/`## Guides`)
- ✅ Link to `CONTRIBUTING.md` if file exists (can be in any section)
- ✅ If no `CONTRIBUTING.md`, basic guidance provided somewhere in README
- ⚠️ If `CONTRIBUTING.md` exists but not linked anywhere: Recommend linking
- ⚠️ If MVP/Production without `CONTRIBUTING.md`: Suggest creating one
**Issue Reporting** (REQUIRED):
- ✅ Issue reporting link or guidance present (can be dedicated `## Bugs` section OR link within `## Contributing`/`## Documentation`)
- ✅ Issue tracker link provided somewhere in README
- ⚠️ If no clear path to report issues: Flag as missing
### 5. Validate Links
**Check documentation links** referenced in README:
1. **Relative links** - Verify files exist:
- `docs/setup.md`
- `docs/architecture.md`
- `adr/`
- `CONTRIBUTING.md`
2. **External links** - Note but don't verify (assume valid):
- GitHub Issues URLs
- API documentation URLs
- Confluence links
3. **Flag broken links**:
```
❌ Broken link: docs/quickstart.md (file not found)
```
### 6. Check for Undiscovered Documentation
**Scan for documentation not linked in README**:
```bash
# Check for common doc files
test -f docs/architecture.md && echo "Architecture doc exists"
test -d adr && echo "ADRs exist"
test -f CONTRIBUTING.md && echo "Contributing guide exists"
```
**If documentation exists but not linked**:
```
⚠️ Found documentation not linked in README:
- docs/architecture.md exists but not linked in Documentation section
- adr/ exists (3 ADRs) but not linked
```
### 7. Generate Compliance Report
**Tier-appropriate validation** using `readme-standards` skill criteria.
**Calculate compliance score**:
- Count required content present (out of 6 core requirements: Title, Description/Overview, Installation, Documentation links, Contributing link, Issue reporting)
- Note: Section names can vary - focus on whether essential content/links exist somewhere in README
- Count optional sections present (out of 2: Badges, Supporting Components)
- Count content quality issues (missing business context, broken links, etc.)

## Output Format
**Console output** - Structured, scannable report with emojis for visual clarity
**Markdown report** - Detailed, archivable document following structure from `readme-standards` skill
## Validation Levels
Using progressive validation from `readme-standards` skill:
**Level 1: Structure** (must pass for minimal compliance):
- All 6 required pieces of content present (title, description/overview, installation, docs links, contributing link, issue reporting)
- Section names can vary - essential content matters more than exact section structure
- Proper heading hierarchy
**Level 2: Content** (standard compliance):
- Business problem/solution context included (in Description, Overview, or separate sections)
- Actionable installation command
- Valid documentation links
- Contributing guidance accessible (dedicated section or link within docs/guides)
- Issue reporting path clear (dedicated section or link within contributing/docs)
**Level 3: Quality** (excellent compliance):
- Tier-appropriate badges
- Comprehensive documentation links (architecture, ADRs, guides)
- CONTRIBUTING.md exists and linked for mature projects
- All available documentation linked appropriately
## Constraints
- **Read-only** - This command does not modify README.md
- **Link validation** - Only check relative links, not external URLs
- **Tier-appropriate** - Validation criteria adjust based on project tier
- **No speculation** - Only flag issues based on actual file checks
- **Actionable recommendations** - Every issue should have clear fix
## Error Handling
**README.md not found**:
- Display clear error message
- Suggest using `/document-generator:generate-readme`
- Stop execution
**Cannot create reports directory**:
- Display error with permission issue
- Suggest alternative output path
**README.md unreadable**:
- Display error (encoding issue, permissions)
- Suggest checking file permissions
## Success Criteria
Validation report should:
- ✅ Accurately identify missing/incomplete sections
- ✅ Provide tier-appropriate recommendations
- ✅ Flag broken links and missing doc references
- ✅ Give clear, actionable next steps
- ✅ Assign appropriate compliance level
## Related Commands
- **`/document-generator:generate-readme`** - Create new README

title: ADR Authoring
description: MADR format structure and best practices for Architecture Decision Records
tags: [adr, documentation, decisions, madr]
---
# ADR Authoring
## Metadata
**Purpose**: Provide MADR template structure and ADR best practices
**Version**: 1.0.0
---
## ADR Template
```markdown
# ADR-XXX: [Short Decision Title]
**Status:** [Proposed/Accepted/Superseded/Rejected]
**Date:** YYYY-MM-DD
**Deciders:** [Names or roles]
**Maturity Level:** [Experimental/Prototype/Production]
**Handoff Impact:** [None/Low/Medium/High]
## Context
[What is the issue we're addressing? What stage of the project are we in?
What business problem or research question drives this decision?]
## Decision Drivers
- [Driver 1: e.g., Must achieve 95% accuracy for business case]
- [Driver 2: e.g., Inference latency must be <100ms]
- [Driver 3: e.g., Solution must be interpretable for business users]
- [Driver 4: e.g., Limited to X budget/compute resources]
## Options Considered
### Option 1: [Name]
**Description:** [Brief explanation]
**Pros:**
- [Advantage 1]
- [Advantage 2]
**Cons:**
- [Disadvantage 1]
- [Disadvantage 2]
**Evaluation Results:** [Benchmark numbers, if applicable]
### Option 2: [Name] ⭐ SELECTED
**Description:** [Brief explanation]
**Pros:**
- [Advantage 1]
- [Advantage 2]
**Cons:**
- [Disadvantage 1]
- [Disadvantage 2]
**Evaluation Results:** [Benchmark numbers, if applicable]
## Decision
We will [clear, active voice statement of what we're doing].
[For production decisions] This will be handed off to [team name] with the following support: [describe transition plan].
## Consequences
### Positive Outcomes
- [What becomes easier or better]
- [Capabilities we gain]
### Negative Outcomes
- [What becomes harder]
- [Capabilities we sacrifice]
### Risks & Mitigation
- **Risk:** [Potential problem]
**Mitigation:** [How we'll address it]
### Implications for Business Team *(if applicable)*
- **What they need to know:** [Critical context for maintenance]
- **What they can modify:** [Safe changes they can make independently]
- **What requires re-engagement:** [Changes that need our team's input]
- **Required expertise:** [Skills needed to maintain this]
## Related ADRs
- Supersedes: [ADR-XXX if replacing an older decision]
- Related to: [ADR-YYY if connected to other decisions]
- Informed by: [ADR-ZZZ if building on previous work]
## References
[Links to detailed documentation, code, experiments, papers, etc.]
```
## Naming and Numbering
**Filename format**: `XXX-title-in-kebab-case.md`
**Sequential numbering**: 001, 002, 003, etc.
**Storage location**: `adr/` directory (Personal standard)
**IMPORTANT**:
- All ADRs MUST be stored in `adr/` directory
- If the `adr/` directory does not exist, create it first: `mkdir -p adr`
- Do NOT store ADRs in `docs/adr/` or any other location
## Maturity Levels
**Experimental** (Tier 1):
- Algorithm selection, feature engineering, evaluation metrics
- Review: Author + 1 peer (1-2 days)
**Prototype** (Tier 2):
- Infrastructure choices, in-market test design, data pipelines
- Review: Author + technical lead + 1 developer (3-5 days)
**Production** (Tier 3):
- Production architecture, monitoring, retraining strategies
- Review: Author + technical lead + business rep (5-7 days with meeting)
## Handoff Impact Levels
- **None**: Internal research decision, no handoff
- **Low**: Minor impact on business team maintenance
- **Medium**: Requires business team understanding
- **High**: Critical for business team success, requires training
## Status Lifecycle
1. **Proposed** - Under review, not yet accepted
2. **Accepted** - Approved and active
3. **Rejected** - Considered but not chosen
4. **Superseded** - Replaced by a newer ADR (reference the new ADR number)
## Best Practices
**Title**:
- Describes the decision, not the problem
- Noun phrase (e.g., "Use of PostgreSQL for feature store")
**Context**:
- What problem are we solving?
- What constraints exist?
- Why does this matter?
**Decision Drivers**:
- List 3-5 key factors influencing the decision
- Be specific (e.g., "Team has PostgreSQL expertise")
**Considered Options**:
- Always include at least 2-3 alternatives
- Show you explored options
**Consequences**:
- Be honest about trade-offs
- List both positive and negative impacts
- Include neutral consequences too
**Links**:
- Reference related ADRs
- Link to external documentation
- Show decision relationships
## When to Write ADRs
**Always write for**:
- Core methodology choices (algorithms, model architecture)
- Data architecture (storage, pipelines, schemas)
- Infrastructure decisions (cloud, framework, deployment)
- Evaluation approach changes
- Decisions persisting to production
- Significant pivots
- Failed experiments (status: Rejected)
**Use judgment for**:
- Temporary workarounds (if marked non-permanent)
- Tool choices for exploration (if not affecting deliverables)
- Hyperparameter decisions (unless novel or critical)
**Don't write for**:
- Individual experiment runs
- Personal workflow preferences
- Notebook organization
- Obvious/trivial choices
**Rule of thumb**: If someone might ask "why did we do it this way?" 6 months from now, write an ADR.

title: Diagram Analysis
description: Understanding system architecture to choose appropriate diagram types
tags: [analysis, diagrams, architecture, visualization]
---
# Diagram Analysis
## Metadata
**Purpose**: Analyze systems to determine best diagram type and content
**Version**: 1.0.0
---
## Analysis Steps
### 1. Understand the Goal
**Ask**:
- What story needs to be told?
- Who is the audience?
- What decisions will this support?
- What level of detail is needed?
### 2. Identify Architecture Type
**Common patterns**:
- **Monolithic** - Single application, internal modules
- **Microservices** - Multiple services, APIs, message queues
- **Data pipeline** - Data flow from sources to outputs
- **ML system** - Training vs inference pipelines
- **Library/Framework** - Class hierarchies, modules
### 3. Choose Diagram Type
**For system overview**: C4 Context
**For service architecture**: C4 Container or Flowchart
**For internal structure**: C4 Component or Class Diagram
**For interactions**: Sequence Diagram
**For data models**: ER Diagram
**For processes**: Flowchart
**For state changes**: State Diagram
### 4. Determine Scope
**Include**:
- Essential components for the story
- Key relationships and dependencies
- Technology choices (if relevant to audience)
**Exclude**:
- Implementation details (unless that's the focus)
- Everything not needed for this specific diagram
- Redundant information
## Discovery Commands
**System boundaries**:
```bash
# Find services/modules
ls -d */ | head -10
find . -name "docker-compose.yml" -o -name "Dockerfile"
```
**Interactions**:
```bash
# Find API definitions
find . -name "*api*.py" -o -name "*route*.py"
# Check for message queues
grep -r "kafka\|rabbitmq\|redis\|celery" pyproject.toml requirements.txt
```
**Data flow**:
```bash
# Find data sources
find . -name "*data*" -o -name "*extract*" -o -name "*load*"
# Check databases
grep -i "postgres\|mysql\|mongo\|sqlite" pyproject.toml requirements.txt
```
## Diagram Planning
**Start simple**:
1. List main components
2. Identify key relationships
3. Choose direction (TD/LR)
4. Add labels
5. Refine as needed
**Validate**:
- Does it tell the right story?
- Is it too complex?
- Is anything missing?
- Will the audience understand it?

title: Git History Analysis
description: Patterns for parsing git commits and PRs to infer changelog entries
tags: [git, commits, changelog, parsing]
---
# Git History Analysis
## Metadata
**Purpose**: Extract changelog entries from git history
**Version**: 1.0.0
---
## Git Log Commands
### Retrieve Commits in Range
**All commits since last tag**:
```bash
git log $(git describe --tags --abbrev=0)..HEAD --pretty=format:"%h|%s|%an|%ad" --date=short
```
**All commits since specific date**:
```bash
git log --since="2025-01-01" --pretty=format:"%h|%s|%an|%ad" --date=short
```
**All commits between two refs**:
```bash
git log v1.0.0..v2.0.0 --pretty=format:"%h|%s|%an|%ad" --date=short
```
**Format explained**:
- `%h` - Short commit hash
- `%s` - Subject/title
- `%an` - Author name
- `%ad` - Author date
- `|` - Delimiter for parsing
### Exclude Noise Commits
**Filter out merge commits**:
```bash
git log --no-merges
```
**Filter out version bump commits**:
```bash
git log --grep="^Bump version" --invert-grep
```
**Combined filters**:
```bash
git log --no-merges --grep="^Bump version\|^Release" --invert-grep
```
## Commit Message Parsing
### Conventional Commits
**Format**: `<type>(<scope>): <description>`
See "Changelog Section Mapping" table below for complete type-to-section mappings.
**Examples**:
```
feat(api): add customer export endpoint → Added
fix(auth): resolve timeout on login → Fixed
perf(db): optimize query performance → Changed
security(deps): update vulnerable packages → Security
```
**Parsing regex**: `^(feat|fix|docs|refactor|perf|test|chore|security)(\([^\)]+\))?: (.+)$`
### Non-Conventional Commits
**Keyword-based categorization**:
**Added indicators**:
- Starts with: "Add", "Implement", "Introduce", "Create"
- Contains: "new feature", "support for"
**Fixed indicators**:
- Starts with: "Fix", "Resolve", "Correct", "Patch"
- Contains: "bug", "issue", "error", "crash"
**Changed indicators**:
- Starts with: "Update", "Improve", "Enhance", "Optimize", "Refactor"
- Contains: "performance", "efficiency"
**Removed indicators**:
- Starts with: "Remove", "Delete", "Drop"
- Contains: "deprecated", "legacy"
**Security indicators**:
- Contains: "security", "vulnerability", "CVE-", "XSS", "injection"
**Example classification**:
```
"Add customer segmentation feature" → Added
"Fix memory leak in batch processing" → Fixed
"Update data validation logic" → Changed
"Remove deprecated API endpoints" → Removed
"Patch security vulnerability in auth" → Security
```
## PR Title Parsing
GitHub/GitLab PR titles often follow similar patterns:
**PR number extraction**:
```bash
gh pr list --state merged --limit 100 --json number,title,mergedAt
```
**Parse PR titles** using same rules as commit messages
**Prefer PR titles over commits** when available (cleaner, more user-facing)
## Extracting PR/Issue References
**From commit messages**:
- Pattern 1: `(#123)` at end of message
- Pattern 2: `#123` anywhere in message
- Pattern 3: `Merge pull request #123`
- Pattern 4: `Fixes #123`, `Closes #123`, `Resolves #123`
**From PR list**:
```bash
# Get PR number associated with commit
gh pr list --state merged --search "sha:COMMIT_HASH" --json number
```
**Link format in changelog**:
- Short form: `(#123)` for PR/issue number
- Full entries: `- Feature description (#123)`
- Multi-ref: `- Feature description (#123, #124)`
## Filtering Strategy
### Skip These Commits
**Merge commits**:
- Pattern: `^Merge (branch|pull request)`
**Version bumps**:
- Pattern: `^(Bump|Release|Version) (version )?[0-9]`
**Internal housekeeping**:
- Pattern: `^(chore|ci|test|docs):`
- Exception: Major docs overhauls might be "Added"
**WIP commits**:
- Pattern: `^WIP:`, `^temp:`, `^tmp:`
### Grouping and Deduplication
**Group by scope** (if using conventional commits):
```
feat(api): add export endpoint
feat(api): add import endpoint
→ Group under "API" subsection in Added
```
**Deduplicate similar commits**:
```
fix: typo in validation message
fix: another typo in error message
→ Combine as "Fixed typos in validation messages"
```
**Squash implementation details**:
```
feat: add customer export (part 1)
feat: add customer export (part 2)
feat: finalize customer export
→ Single entry: "Customer export feature"
```
## Changelog Section Mapping
**Type → Section mapping**:
| Commit Type | Changelog Section | Notes |
|-------------|-------------------|-------|
| `feat` | Added | New features |
| `fix` | Fixed | Bug fixes |
| `perf` | Changed | Performance improvements |
| `refactor` | Changed | Only if user-facing |
| `security` | Security | Security patches |
| `deprecate` | Deprecated | Features marked for removal |
| `remove` | Removed | Deleted features |
| `docs` | (Skip) | Unless major docs addition |
| `test` | (Skip) | Internal only |
| `chore` | (Skip) | Internal only |
| `ci` | (Skip) | Internal only |
## Extracting User-Facing Changes
**Focus on impact, not implementation**:
**Good**: "Added support for multi-year trend analysis"
**Bad**: "Refactored TrendAnalyzer class to support configurable date ranges"
**Transformation examples**:
```
Git: "refactor: extract validation logic to separate module"
→ Skip (internal refactoring)
Git: "feat: implement caching layer for API responses"
→ Added: "API response caching for improved performance"
Git: "fix: handle edge case in date parsing"
→ Fixed: "Corrected date parsing for edge cases"
Git: "perf(db): add indexes to customer table"
→ Changed: "Improved database query performance"
```
## Git Commands Summary
**Get commits since last version**:
```bash
git log $(git describe --tags --abbrev=0)..HEAD --no-merges --pretty=format:"%h|%s"
```
**Get all tags** (for version detection):
```bash
git tag --list --sort=-version:refname
```
**Get commit count** (for version increment hint):
```bash
git rev-list --count $(git describe --tags --abbrev=0)..HEAD
```
**Check if commit is a merge**:
```bash
git rev-list --parents -n 1 <commit-hash> | grep -q " .* .*"
```
## Best Practices
1. **Prefer PR titles** over individual commits when available
2. **Group related changes** by feature or component
3. **Use user-facing language**, avoid technical jargon
4. **Skip internal commits** that don't affect users
5. **Combine granular commits** into cohesive changelog entries
6. **Link to issues/PRs** for detailed context
7. **Preserve intent**, even if wording changes
## Example Workflow
1. Get commits: `git log v1.0.0..HEAD --no-merges`
2. Parse each commit message
3. Classify by type (feat/fix/etc.)
4. Filter out internal commits
5. Group by scope or feature
6. Rephrase in user-facing language
7. Map to changelog sections
8. Deduplicate and clean up
9. Format as changelog entries

# Mermaid Diagramming
## Metadata
**Purpose**: Mermaid syntax reference and best practices for all diagram types
**Version**: 1.0.0
---
## Diagram Type Selection
| Diagram Type | Use When | Example Use Case |
|-------------|----------|------------------|
| **C4 Context** | System in environment | "How does our ML platform fit in the org?" |
| **C4 Container** | Services and tech stack | "What are our main services?" |
| **Flowchart** | Process flow, algorithms, decision trees | "How does model training work?" |
| **Sequence** | Interactions over time, API calls | "What happens during API call?" |
| **ER Diagram** | Database schemas, data models | "What's the feature store structure?" |
| **Class** | OOP design, inheritance | "What's our model class hierarchy?" |
| **State** | Entity lifecycles, state machines | "Model deployment states?" |
| **Gantt** | Project timelines, schedules | "Release timeline?" |
| **Journey** | User journeys, experiences | "User onboarding flow?" |
| **Git Graph** | Branching strategies | "Release workflow?" |
## Syntax Examples
### C4 Context Diagram
```mermaid
C4Context
title System Context
Person(user, "User", "Description")
System(sys, "System", "What it does")
System_Ext(external, "External System", "Description")
Rel(user, sys, "Uses", "HTTPS")
Rel(sys, external, "Reads from", "API")
```
### Flowchart
```mermaid
flowchart TD
Start([Begin]) --> Step1[Process Data]
Step1 --> Decision{Valid?}
Decision -->|Yes| Step2[Continue]
Decision -->|No| Error[Handle Error]
Step2 --> End([Complete])
Error --> End
```
### Sequence Diagram
```mermaid
sequenceDiagram
actor User
participant API
participant Service
User->>+API: Request
API->>+Service: Process
Service-->>-API: Result
API-->>-User: Response
```
### ER Diagram
```mermaid
erDiagram
MODEL ||--o{ PREDICTION : generates
MODEL {
string model_id PK
string name
datetime created
}
PREDICTION {
string id PK
string model_id FK
json result
}
```
## Best Practices
**Clarity**:
- Use descriptive labels
- Keep diagrams focused (one concern)
- Avoid clutter
- Add legends if needed
**Styling**:
- Consistent naming
- Logical flow direction
- Group related items
- Use color sparingly
**Maintainability**:
- Add comments for complex parts
- Structure code clearly
- Make updates easy
## Common Patterns
**Direction**:
```
flowchart TD # Top-Down
flowchart LR # Left-Right
flowchart BT # Bottom-Top
flowchart RL # Right-Left
```
**Node shapes** (flowchart):
```
[Rectangle]
(Rounded)
([Stadium])
[[Subroutine]]
{Diamond}
```
**Relationships** (sequence):
```
->> Solid arrow
-->> Dotted arrow
->>+ Activate
-->>- Deactivate
```
## Styling and Theming
**Standard colors for personal use diagrams**:
```
style Research fill:#fff4e6 # Light orange - research/experimental
style Production fill:#e6f3ff # Light blue - production/library
style Data fill:#e6ffe6 # Light green - data stores
style External fill:#ffe6e6 # Light red - external systems
```
**Subgraphs for boundaries**:
```mermaid
flowchart LR
subgraph Research["Research Area"]
N1[Notebook]
end
subgraph Production["Production"]
S1[Service]
end
N1 -.-> S1
```
**Provide both versions**:
- Basic: Clean diagram without styling
- Styled: With colors, themes, and visual enhancements
## Alignment with Repo-Investigator
When visualizing data/information flow (similar to `/repo-investigator:visualize-flow`):
- Use **subgraphs** to distinguish Research vs Library boundaries
- Use **dotted arrows** (-.->) for hand-off/promotion paths
- Follow same color scheme: orange for research, blue for production
- Show data sources, transformations, outputs, and consumers

### Badge Options Reference
**Standard Personal badge format**:
Badges should be wrapped in HTML comments for maintainability:
```markdown
<!-- badges: start -->
[Badge 1]
[Badge 2]
...
<!-- badges: end -->
```
**Available badge types** (select based on project tier and applicability):
| Badge Type | Example | When to Use | Source |
|------------|---------|-------------|--------|
| **Version/Release** | `[![Releases](https://img.shields.io/badge/released-2.17.0.0-blue.svg)](https://github.com/USERNAME/project/releases)` | All projects with releases | Git tags, `pyproject.toml`, `package.json` |
| **Lifecycle** | `[![Lifecycle](https://img.shields.io/badge/lifecycle-experimental-orange.svg)](https://www.tidyverse.org/lifecycle/#experimental)` | All tiers (orange=prototype, yellow=mvp, green=production) | Project tier detection |
| **Documentation** | `[![Docs](https://img.shields.io/badge/docs-latest-brightgreen.svg?style=flat)](https://your-project-docs-url/)` | MVP/Production with published docs | Docs URL or relative link |

**Lifecycle badge color scheme**:
- **Experimental/Prototype**: `orange` - Research, exploratory, not production-ready
- **MVP/Maturing**: `yellow` - Pilot deployment, active development
- **Stable/Production**: `green` - Production-ready, maintained
**Tier-specific badge recommendations**:
| **Tier** | **Recommended Badges** |
|----------|------------------------|
| **Prototype** | Optional: Version, Lifecycle (experimental-orange) |
| **MVP** | Version, Lifecycle (mvp-yellow), Docs |
| **Production** | Version, Lifecycle (stable-green), Docs, Python version (if applicable), Code style, Pre-commit |
**Detection logic**:
```python
# Detect applicable badges from project files
badges = []
# Version/Release (always try to detect)
if has_git_tags or has_version_in_metadata:
badges.append(("Releases", version_number, releases_url))
# Lifecycle (required for all tiers)
tier = detect_project_tier() # prototype, mvp, production
lifecycle_colors = {"prototype": "orange", "mvp": "yellow", "production": "green"}
badges.append(("Lifecycle", tier, lifecycle_colors[tier]))
# Documentation (if docs exist)
if docs_url or has_docs_directory:
badges.append(("Docs", "latest", docs_url))
# Python-specific badges (only for Python projects)
if is_python_project:
if has_python_version_constraint:
badges.append(("Python version", python_version, python_docs_url))
if uses_black_formatter:
badges.append(("Code style: black", None, black_url))
if uses_ruff_linter:
badges.append(("Ruff", None, ruff_badge_url))
# Pre-commit (language-agnostic)
if has_precommit_config:
badges.append(("pre-commit", "enabled", precommit_url))
```
**Example badge blocks by tier**:
**Prototype tier** (minimal or no badges):
```markdown
<!-- badges: start -->
[![Lifecycle](https://img.shields.io/badge/lifecycle-experimental-orange.svg)](https://www.tidyverse.org/lifecycle/#experimental)
<!-- badges: end -->
```
**MVP tier** (recommended badges):
```markdown

[![Lifecycle](https://img.shields.io/badge/lifecycle-mvp-yellow.svg)](https://www.tidyverse.org/lifecycle/#maturing)
[![Docs](https://img.shields.io/badge/docs-available-brightgreen.svg?style=flat)](./docs/usage.md)
<!-- badges: end -->
```
**Production tier** (full badge set):
```markdown
<!-- badges: start -->
[![Releases](https://img.shields.io/badge/released-2.17.0.0-blue.svg)](https://github.com/USERNAME/project/releases)
[![Lifecycle](https://img.shields.io/badge/lifecycle-stable-green.svg)](https://www.tidyverse.org/lifecycle/#stable)

[![pre-commit](https://img.shields.io/badge/pre--commit-enabled-brightgreen?logo=pre-commit&logoColor=white)](https://github.com/pre-commit/pre-commit)
<!-- badges: end -->
```
**Important notes**:
- Only include badges that are accurate and verifiable
- Don't add Python-specific badges to non-Python projects
- Badge URLs should link to meaningful resources (releases page, docs site, tool documentation)
- Use HTML comment wrappers for easy maintenance
---
### Markdown Formatting Standards
**Heading hierarchy**:
- `#` - Project title only
- `##` - Section headings (Description, Installation, etc.)
- `###` - Subsections (if needed, but keep minimal)
**Code blocks**:
- Always specify language: \`\`\`bash, \`\`\`python, \`\`\`json
- Use for installation commands, API examples
**Links**:
- Relative links for internal docs: `[Setup](docs/setup.md)`
- Absolute links for external resources: `[GitHub Issues](https://github.com/...)`
- Use descriptive link text, not "click here"
**Lists**:
- Use `-` for unordered lists (consistent with style)
- Use `1.` for ordered lists (auto-numbering)
---
### Context Extraction Patterns
**Python projects** - Read these files in order:
1. `pyproject.toml` - `project.name`, `project.description`, `project.version`
2. `setup.py` - `name`, `description`, `version` if no pyproject.toml
3. `requirements.txt` - Dependencies list
4. Main module docstring - Business context
**JavaScript projects** - Read these files:
1. `package.json` - `name`, `description`, `version`
2. `README.md` - Existing content to preserve
3. Main file docstring - Business context
**Documentation discovery**:
- Architecture: `docs/architecture.md`, `*.drawio`, `*.mmd`
- ADRs: `adr/`, `docs/adr/`
- Setup: `docs/setup.md`, `docs/installation.md`, `INSTALL.md`
- Contributing: `CONTRIBUTING.md`, `docs/contributing.md`
---
## Resources
### Tier-Specific README Example (MVP)
```markdown
# Feature Store API
![Version](https://img.shields.io/badge/version-0.2.0-blue)
![Lifecycle](https://img.shields.io/badge/lifecycle-mvp-yellow)
![Docs](https://img.shields.io/badge/docs-available-green)
![Code Style](https://img.shields.io/badge/code%20style-black-black)
RESTful API for serving customer features to ML models and analytics tools.
## Description
Data scientists need consistent, versioned access to customer features across projects, but currently extract features redundantly from raw data sources. This API provides a centralized feature store with versioning, caching, and real-time serving (<50ms p95).
## Installation
\`\`\`bash
pip install feature-store-client
\`\`\`
For local development, see [Setup Guide](docs/setup.md).
## Documentation
- [Quickstart Guide](docs/quickstart.md) - Get started in 5 minutes
- [API Reference](docs/api.md) - Complete endpoint documentation
- [Architecture](docs/architecture.md) - System design and data flow
- [ADRs](adr/) - Architecture Decision Records
## Supporting Components
- [Feature Pipeline](https://github.com/USERNAME/feature-pipeline) - Batch computation
- [Redis Cluster](internal-link) - Cache layer
## Contributing
See [CONTRIBUTING.md](CONTRIBUTING.md) for guidelines on reporting bugs, submitting changes, and running tests.
## Bugs & Enhancements
Report bugs via [GitHub Issues](https://github.com/USERNAME/feature-store-api/issues).
```
**Tier variations**: Prototype skips badges/components; Production adds comprehensive docs (runbooks, monitoring, deployment guides).
**Business context integration**: See `readme-standards` skill "Before/After Examples" for good/bad business context patterns.
---
### Edge Case Handling
**No project metadata found**:
- Prompt user: "What is the project name?"
- Prompt user: "Provide a one-sentence description"
**No business context found**:
- Prompt user: "What business problem does this solve?"
- Prompt user: "What solution does this project provide?"
- If user unsure: Generate technical description from code analysis
**No documentation exists**:
```markdown
## Documentation
- See inline code documentation and docstrings for implementation details
- Architecture documentation coming soon
For questions, contact [team/person].
```
**No CONTRIBUTING.md**:
- Generate basic contributing section inline (see template above)
- Suggest creating CONTRIBUTING.md for mature projects
**No tests detected**:
- In Contributing section, note: "Please include tests with your contributions"
- Don't specify test command if none exists
---
### Tier-Specific Variations
| **Section** | **Prototype** | **MVP** | **Production** |
|-------------|---------------|---------|----------------|
| **Badges** | Optional (skip) | Include basic badges | Full badge set |
| **Description** | Brief (2-3 sentences) | Moderate (3-4 sentences) | Comprehensive (4-5 sentences) |
| **Documentation Links** | Minimal (notebooks, basic docs) | Moderate (quickstart, API, architecture) | Comprehensive (all resources) |
| **Supporting Components** | Usually none | May have 1-2 dependencies | Multiple service dependencies |
| **Contributing** | Basic inline guidance | Link to CONTRIBUTING.md | Full process documentation |
---
### Link Validation
Before adding links to Documentation section:
1. **Verify file exists**: Use file system check
2. **If missing**: Don't add placeholder link
3. **Suggest creation**: Note in validation report that docs should be created
**Example validation logic**:
```python
docs_to_check = [
("Quickstart", "docs/quickstart.md"),
("Architecture", "docs/architecture.md"),
("ADRs", "adr/"),
]
valid_links = []
for name, path in docs_to_check:
if file_exists(path):
valid_links.append((name, path))
```
---
**Remember**: The goal is **minimal, focused READMEs** that serve as clear entry points. Link to detailed documentation rather than embedding everything inline.

# README Standards for Personal
## Metadata
**Purpose**: Define minimal README structure and validation rules
**Version**: 1.0.0
---
## Instructions
### 8-Section Minimal Structure
All Personal READMEs must follow this **minimal structure**:
1. ✅ **Project Title & One-Liner** (REQUIRED)
2. ℹ️ **Badges Block** (OPTIONAL - include for MVP/Production tiers)
3. ✅ **Short Description** (REQUIRED - must integrate business problem/solution)
4. ✅ **Installation** (REQUIRED)
5. ✅ **Documentation** (REQUIRED - can be dedicated section or part of guides/resources section)
6. ℹ️ **Supporting Components** (OPTIONAL - only if dependencies exist)
7. ✅ **Contributing Link** (REQUIRED - can be dedicated section or link within documentation section)
8. ✅ **Issue Reporting** (REQUIRED - can be dedicated bugs section or link within documentation/contributing)
**Key principles**:
- **Link-first**: Point to detailed docs, don't embed everything inline
- **Concise**: Keep README minimal, use links for depth
- **Flexible structure**: Section names can vary (e.g., "Description" or "Overview", "Guides" can contain contributing/docs links)
- **Essential content over format**: Ensure contributing links and issue reporting exist, regardless of exact section structure
- **Actionable**: Clear installation steps and contribution guidance
---
### Section Validation Matrix
| Section | Heading | Required Content | Validation Checks |
|---------|---------|------------------|-------------------|
| **1. Title & One-Liner** | `# {Name}` | 1-2 sentence description | ✅ Title present<br>✅ Specific description (not vague) |
| **2. Badges** *(optional)* | `<!-- badges: start -->`<br>`...badges...`<br>`<!-- badges: end -->` | Version, Lifecycle, Docs (MVP/Production)<br>+ Python version, Code Style, Pre-commit (Production Python projects) | ℹ️ Note if missing (MVP/Production tier)<br>✅ Wrapped in HTML comments<br>✅ shields.io format<br>✅ Lifecycle color matches tier (orange/yellow/green)<br>⚠️ Python badges on non-Python projects |
| **3. Description** | `## Description` or `## Overview` | Business problem + solution + functionality (3-5 sentences) | ✅ Heading present (Description/Overview acceptable)<br>✅ Business context included<br>ℹ️ Separate Business Problem section allowed if brief |
| **4. Installation** | `## Installation` | Actionable command + optional setup link | ✅ Code block with command<br>✅ Link to `docs/setup.md` if exists |
| **5. Documentation** | `## Documentation` or within `## Guides` | Bulleted links (only existing docs) | ✅ 1+ link provided<br>✅ ADRs linked if `adr/` exists<br>✅ Links valid (no placeholders) |
| **6. Supporting Components** *(optional)* | `## Supporting Components` | Dependency list with links | ℹ️ Skip for standalone projects<br>✅ Each dependency has link + description |
| **7. Contributing Link** | `## Contributing` or within `## Documentation`/`## Guides` | Link to CONTRIBUTING.md or inline guidance | ✅ Contributing link/guidance present (dedicated section OR within docs section)<br>✅ Link if CONTRIBUTING.md exists<br>⚠️ Suggest CONTRIBUTING.md for MVP/Production |
| **8. Issue Reporting** | `## Bugs`, `## Bugs & Enhancements`, or within `## Contributing` | Issue tracker link | ✅ Issue reporting link present (dedicated section OR within contributing/docs)<br>✅ Clear call-to-action |
**Common validation flags**:
- ✅ **Compliant** - Section meets all requirements
- ⚠️ **Incomplete** - Section present but missing key content
- ❌ **Non-compliant** - Wrong structure (e.g., separate Business Problem section)
- ℹ️ **Optional** - Note if missing but don't fail validation

- **MVP**: Basic CI/CD, test coverage setup, some docs, pilot deployment
- **Production**: Full CI/CD, comprehensive tests, extensive docs, production deployment
---
### Link Validation Rules
**Required link checks**:
1. **Architecture docs**: If `docs/architecture.md` or `.drawio` exists, must be linked in Documentation section
2. **ADRs**: If `adr/` directory exists with ADRs, must be linked in Documentation section
3. **CONTRIBUTING.md**: If exists, must be linked in Contributing section
4. **Setup guide**: If `docs/setup.md` exists, should be linked in Installation section
**Broken link detection**:
- Verify relative links point to existing files
- Flag broken links as compliance issue
- Don't flag external URLs (assume valid unless HTTP check requested)
---
### Common Compliance Issues
**Issue 1: Separate Business Problem/Solution sections**
- ℹ️ Acceptable: `## Business Problem` and `## Solution` as separate sections (if brief and focused)
- ✅ Preferred: Integrate into `## Description` or `## Overview` paragraph for conciseness
**Issue 2: Embedding full setup instructions**
- ❌ Non-compliant: Detailed setup steps in README Installation section
- ✅ Fix: Simple install command + link to `docs/setup.md`
**Issue 3: Missing business context**
- ⚠️ Incomplete: Description only has technical details, no problem/solution context
- ✅ Fix: Add sentence explaining what business problem this solves
**Issue 4: Placeholder documentation links**
- ❌ Non-compliant: Linking to `docs/architecture.md` when file doesn't exist
- ✅ Fix: Only link to docs that exist; note missing docs in validation report
**Issue 5: Testing instructions in README**
- ❌ Non-compliant: Full testing guide embedded in README
- ✅ Fix: Move testing instructions to `CONTRIBUTING.md`, link from README
**Issue 6: Missing badges for Production project**
- ⚠️ Incomplete: Production-tier project without badges
- ✅ Fix: Add full badge set (version, lifecycle-green, docs, Python version, code style, pre-commit)
**Issue 7: Badges not wrapped in HTML comments**
- ⚠️ Incomplete: Badges present but missing `<!-- badges: start/end -->` wrappers
- ✅ Fix: Wrap badge block in HTML comments for maintainability
**Issue 8: Incorrect lifecycle badge color**
- ⚠️ Incomplete: MVP project with "experimental" (orange) badge instead of "mvp" (yellow)
- ✅ Fix: Match lifecycle badge color to project tier (orange=prototype, yellow=mvp, green=production)
**Issue 9: Python badges on non-Python project**
- ❌ Non-compliant: Python version, black, or ruff badges on JavaScript/other project
- ✅ Fix: Remove language-specific badges from non-applicable projects
---
### Integration with MTPS (Minimum Transferrable Project Standards)
The README standards align with MTPS requirements:
**Documentation Standard** (from MTPS):
- README.md with business problem, solution, setup → ✅ Covered by sections 1, 3, 4
- Architecture diagram or description → ✅ Linked in Documentation section
- Handoff summary → ✅ Separate document (not in README)
**README's role in MTPS**:
- Entry point to project documentation
- Links to architecture, ADRs, contributing guides
- Does NOT replace comprehensive documentation
- Minimal structure keeps it maintainable

- Proper heading hierarchy
**Level 2: Content** (should pass):
- Business problem/solution in Description
- Actionable installation command
- Valid documentation links
- Clear contributing guidance
**Level 3: Quality** (nice to have):
- Tier-appropriate badges
- Comprehensive documentation links
- CONTRIBUTING.md for mature projects

description: Validation rules for semantic and calendar versioning
tags: [versioning, semver, calver, validation]

# Version Validation
## Metadata
**Purpose**: Validation rules for semantic and calendar versioning
**Version**: 1.0.0
---
## Version Types
### Semantic Versioning (SemVer)
**Format**: `MAJOR.MINOR.PATCH` (e.g., 2.9.1)
**Rules**:
- MAJOR: Breaking changes, incompatible API changes
- MINOR: New features, backward-compatible
- PATCH: Bug fixes, backward-compatible
**Examples**:
- `1.0.0` - Initial stable release
- `1.1.0` - Added new feature
- `1.1.1` - Fixed bug
- `2.0.0` - Breaking change
**Regex Pattern**: `^\d+\.\d+\.\d+$`
### Calendar Versioning (CalVer)
**Format**: `YYYY.MINOR` or `YYYY.MM.PATCH` (e.g., 2025.1 or 2025.11.2)
**Rules**:
- YYYY: Year (4 digits)
- MINOR: Sequential release number within year (starts at 1)
- MM: Month (01-12)
- PATCH: Bug fix number within month
**Examples**:
- `2025.1` - First release of 2025
- `2025.2` - Second release of 2025
- `2025.11.1` - First patch in November 2025
**Regex Patterns**:
- Year.Minor: `^\d{4}\.\d+$`
- Year.Month.Patch: `^\d{4}\.(0[1-9]|1[0-2])\.\d+$`
## Version Detection
**Auto-detect version type** from existing versions:
1. Check existing changelog for version patterns
2. Check git tags: `git tag --list`
3. Check project metadata:
- Python: `pyproject.toml` or `setup.py`
- Node: `package.json`
4. Default to SemVer if ambiguous
**Detection Logic**:
```
If version matches YYYY.N pattern → CalVer
If version matches X.Y.Z pattern → SemVer
If no existing versions → Ask user or default to SemVer
```
## Validation Rules
### Chronological Ordering
Versions MUST appear in reverse chronological order (newest first):
**Correct**:
```markdown
## [2.1.0] - 2025-11-01
## [2.0.0] - 2025-09-15
## [1.5.0] - 2025-06-10
```
**Incorrect**:
```markdown
## [1.5.0] - 2025-06-10
## [2.0.0] - 2025-09-15 ❌ Out of order
## [2.1.0] - 2025-11-01
```
### Version Increment Rules
**SemVer**:
- MAJOR increments reset MINOR and PATCH to 0 (2.3.1 → 3.0.0)
- MINOR increments reset PATCH to 0 (2.3.1 → 2.4.0)
- PATCH increments by 1 (2.3.1 → 2.3.2)
**CalVer (Year.Minor)**:
- Year changes reset MINOR to 1 (2024.5 → 2025.1)
- Within same year, MINOR increments (2025.1 → 2025.2)
**CalVer (Year.Month.Patch)**:
- New month resets PATCH to 1 (2025.10.3 → 2025.11.1)
- Within same month, PATCH increments (2025.11.1 → 2025.11.2)
### Date Validation
Dates MUST:
- Use ISO format: `YYYY-MM-DD`
- Be valid dates (no Feb 30, etc.)
- Match or precede version dates in chronological order
- Not be in the future (warning, not error)
**Regex**: `^\d{4}-(0[1-9]|1[0-2])-(0[1-9]|[12]\d|3[01])$`
## Common Validation Errors
| Error Type | Example | Issue | Fix |
|------------|---------|-------|-----|
| **Invalid Version Format** | `## [v2.1.0] - 2025-11-01`<br>`## [2.1] - 2025-11-01`<br>`## [25.1] - 2025-11-01` | 'v' prefix in brackets<br>Incomplete SemVer (missing PATCH)<br>Incomplete year (use 2025, not 25) | Remove prefix, use complete version format |
| **Incorrect Date Format** | `## [2.1.0] - 11/01/2025`<br>`## [2.1.0] - 2025-Nov-01`<br>`## [2.1.0] - 2025-11-1` | Wrong format (MM/DD/YYYY)<br>Month as text<br>Missing leading zero | Use `YYYY-MM-DD` format |
| **Version Skip** | `## [2.1.0] - 2025-11-01`<br>`## [1.9.0] - 2025-09-15` | Skipped version 2.0.0 | Warning - may indicate missing entry |
| **Date Ordering** | `## [2.1.0] - 2025-09-01`<br>`## [2.0.0] - 2025-11-01` | Later date for earlier version | Ensure dates are chronological |
## Version Comparison
**SemVer Comparison**:
```
2.1.0 > 2.0.5 > 2.0.0 > 1.9.9
```
**CalVer Comparison** (Year.Minor):
```
2025.5 > 2025.1 > 2024.12 > 2024.1
```
**CalVer Comparison** (Year.Month.Patch):
```
2025.11.2 > 2025.11.1 > 2025.10.5 > 2024.12.1
```
## Auto-increment Logic
**SemVer**:
- For features: Increment MINOR (2.1.3 → 2.2.0)
- For fixes: Increment PATCH (2.1.3 → 2.1.4)
- For breaking changes: Increment MAJOR (2.1.3 → 3.0.0)
**CalVer (Year.Minor)**:
- Same year: Increment MINOR (2025.1 → 2025.2)
- New year: Reset to YEAR.1 (2024.5 → 2025.1)
**CalVer (Year.Month.Patch)**:
- Same month: Increment PATCH (2025.11.1 → 2025.11.2)
- New month: YEAR.MONTH.1 (2025.10.3 → 2025.11.1)
