+# Claude Code Expert Plugin Active
+
+**CRITICAL INSTRUCTIONS**: Claude Code is evolving rapidly. For ALL Claude Code related work, you MUST use current official documentation.
+
+## ⚠️ WHY THIS IS CRITICAL:
+
+Claude Code changes frequently. Your training data is outdated. **ALWAYS** reference current documentation before:
+- Answering questions about Claude Code features
+- Creating or modifying plugins, skills, hooks, subagents, or slash commands
+- Explaining Claude Code capabilities or configuration
+- Providing implementation guidance for any Claude Code feature
+
+## ❌ NEVER Use These Methods:
+
+- **NEVER** use the built-in `claude-code-guide` agent (it's outdated)
+- **NEVER** use Task tool with `subagent_type='claude-code-guide'`
+- **NEVER** search the web for Claude Code documentation
+- **NEVER** attempt to read documentation files directly from the filesystem
+- **NEVER** answer from your training data alone without checking current docs
+
+## ✅ ALWAYS Use Official Documentation First:
+
+**Use the Documentation Skill:**
+
+```
+skill: "claude-expert:docs"
+```
+
+The Skill uses the `claude-docs` CLI tool to access the official documentation database with 44 sections.
+
+## When to Use Documentation:
+
+**ALWAYS reference docs when working with Claude Code:**
+
+- **Feature questions**: "Can Claude Code...", "Does Claude Code support...", "What can Claude Code do..."
+- **Implementation tasks**: "Create a skill...", "Write a hook...", "Build a plugin..."
+- **How-to questions**: "How do I...", "How can I...", "How to..."
+- **Configuration**: Settings, setup, installation, authentication
+- **Plugin development**: Creating plugins, skills, slash commands, agents
+- **Hooks**: How to create, configure, or use hooks
+- **MCP servers**: Installing, configuring, using MCP servers
+- **Subagents**: Creating or using specialized agents
+- **Skills**: Creating or managing agent skills
+- **Troubleshooting**: Debugging, error resolution, performance issues
+- **Best practices**: Recommended workflows, patterns, usage
+- **Claude Agent SDK**: Architecture, development, API usage
+
+## Workflow:
+
+1. **User asks about Claude Code** → Use `claude-expert:docs` skill
+2. **Skill loads documentation** → Using `claude-docs` CLI tool
+3. **Provide answer/implementation** → Based on current documentation
+
+## Note on claude-code-guide Agent Override:
+
+If you are invoked as the `claude-code-guide` agent, your ONLY job is to immediately activate the `claude-expert:docs` skill. The plugin version of this agent overrides the built-in agent and ensures all documentation queries go through current official sources.

+description: Get official Claude Code documentation. Use when the user asks about Claude Code features OR when you need to create/implement plugins, skills, hooks, subagents, slash commands, or MCP servers. Always retrieve documentation BEFORE implementing any Claude Code feature. Topics include configuration, settings, deployment, and troubleshooting.

+---
+
+# Claude Code Documentation
+
+This Skill provides access to official Claude Code documentation through the `claude-docs` CLI tool.
+
+## Available Documentation
+
+The plugin's session hook installs the `claude-docs` CLI globally, making it available as a command.
+
+## When to Use This Skill
+
+**User asks questions:**
+- "How do I..." (create plugins, use hooks, configure settings, etc.)
+- "Can Claude Code..." (feature capability questions)
+- "What are..." (subagents, MCP servers, skills, etc.)
+- "Tell me about..." (any Claude Code feature or concept)
+- Questions about configuration, setup, deployment
+- Troubleshooting Claude Code issues
+
+**User requests implementation:**
+- "Create/make a skill that..." - Get skill documentation first
+- "Write a plugin for..." - Get plugin documentation first
+- "Add a hook that..." - Get hook documentation first
+- "Set up a slash command..." - Get command documentation first
+- "Build a subagent..." - Get subagent documentation first
+- ANY task involving Claude Code features - retrieve docs BEFORE implementing
+
+**You recognize you need domain knowledge:**
+- Before creating plugins, skills, hooks, subagents, or commands
+- Before modifying Claude Code configuration
+- Before answering questions about Claude Code capabilities
+- When you're unsure about the correct way to implement a Claude Code feature
+
+## How to Use the CLI Tool
+
+### Step 1: Identify what documentation is needed
+
+Determine the topic from the user's question:
+- plugins, hooks, skills, mcp, agents, slash commands, settings, etc.
+
+### Step 2: Load ALL related documentation
+
+**Common topics and their related slugs (load ALL):**
+- **plugins** → `plugins`, `plugin-marketplaces`, `plugins-reference`
+- **hooks** → `hooks-guide`, `hooks`
+- **skills** → `skills`
+- **mcp** → `mcp`
+- **agents/subagents** → `sub-agents`
+- **slash commands** → `slash-commands`
+- **settings** → `settings`
+- **security/iam** → `security`, `iam`
+- **monitoring** → `monitoring-usage`, `analytics`, `costs`
+
+### Step 3: Use the CLI tool with Bash
+
+**Load full documents (default approach):**
+```bash
+claude-docs get plugins
+claude-docs get plugin-marketplaces
+claude-docs get plugins-reference
+```
+
+**Browse document structure (if needed):**
+```bash
+# See list of all available docs
+claude-docs list
+
+# See table of contents for a specific document
+claude-docs list plugins
+```
+
+**Search for specific topics:**
+```bash
+claude-docs search 'oauth'
+claude-docs search 'environment variables'
+```
+
+**Get specific section (only if specifically requested):**
+```bash
+claude-docs get 'plugins#quickstart'
+```
+
+## Key Principles
+
+1. **Load full documents first** - `get <slug>` loads the entire document including all sections
+2. **Load ALL related docs** - Don't load just one if multiple exist for a topic
+3. **Avoid anchors unless needed** - Full documents are usually better than subsections
+4. **Be comprehensive** - When in doubt, load more documentation rather than less
+
+## What NOT to Do
+
+- ❌ Don't answer from training data without checking current docs
+- ❌ Don't use anchors (`get <slug>#<anchor>`) unless user specifically requests a section
+- ❌ Don't load just one doc when multiple related ones exist
+- ❌ Don't search the web before checking official documentation
+
+## Example Workflows
+
+**User asks:** "How do I create a plugin with hooks?"
+
+1. Identify topics: plugins + hooks
+2. Load all related documentation:
+   ```bash
+   claude-docs get plugins
+   claude-docs get plugin-marketplaces
+   claude-docs get plugins-reference
+   claude-docs get hooks-guide
+   claude-docs get hooks
+   ```
+3. Provide comprehensive answer from loaded docs
+
+**User asks:** "What are Skills?"
+
+1. Identify topic: skills
+2. Load documentation:
+   ```bash
+   claude-docs get skills
+   ```
+3. Explain Skills concept from documentation
+
+**User asks:** "Can you help me set up MCP servers?"
+
+1. Identify topic: mcp
+2. Load documentation:
+   ```bash
+   claude-docs get mcp
+   ```
+3. Provide setup instructions from docs
+
+## Remember
+
+- The `claude-docs` CLI is installed globally (managed by the plugin's session hook)
+- Always load documentation BEFORE implementing Claude Code features
+- Documentation is locally cached and fast to retrieve
+- Full documents are comprehensive - you usually don't need subsections
+- After loading docs, provide answers based on official information
+
+This Skill ensures you always have accurate, up-to-date Claude Code documentation when needed.
