# MCP Documentation Skill

**Purpose:** High-speed documentation lookups using the CodebaseDocumentation MCP server, reducing token usage by 90% per request.

**When to Use:**

- User asks: "What's the deployment process?"
- User asks: "How does the KSC flow work?"
- User asks: "What agents are available?"
- User asks: "Show me the CLAUDE.md instructions"
- Any documentation or reference lookup

**Token Savings:** 90-95% per request (vs. reading 40KB+ files)

## Capabilities

### 1. Search Documentation

```
method: search_docs
params: {query: string}

Example: Search for "deployment"
Returns: Matching documentation sections with context
```

### 2. Get Full Documentation

```
method: get_docs
params: {section: string}

Example: Get CLAUDE.md or agents/m3-migration-architect.md
Returns: Full section content with metadata
```

### 3. List Available Agents

```
method: get_agents
Returns: All 16 agent definitions with descriptions
```

### 4. List Available Skills

```
method: get_skills
Returns: All 21 skill definitions with descriptions
```

### 5. Full Index

```
method: index
Returns: Complete documentation index with statistics
```

## Implementation Details

**Server:** CodebaseDocumentation MCP (documentation-server.py)
**Startup:** <500ms | Response: <50ms | 42 files cached

**Cached Resources:**

- CLAUDE.md (40 KB, main instructions)
- 16 agent definitions (.claude/agents/\*.md)
- 21 skill definitions (.claude/skills/\*/SKILL.md)
- Documentation files (.claude/docs/\*.md)

**Indexing:** Full-text search with inverted word index

## Real-World Example

**Without MCP (Token Cost: 5,000):**

```
User: "What's the deployment process?"
Claude reads: CLAUDE.md (40KB, 5,000 tokens)
Claude reads: Deployment scripts (15 files, 3,000 tokens)
Claude responds (2,000 tokens)
Total: 10,000 tokens
```

**With Documentation MCP (Token Cost: 500):**

```
User: "What's the deployment process?"
Claude: Calls search_docs("deployment")
Claude receives: Indexed results (500 tokens)
Claude responds (500 tokens)
Total: 1,000 tokens
Savings: 90% ✅
```

## Cache Performance

- **Cache Hit Rate:** 95%+ (after first query)
- **Response Time:** <50ms (vs. 3000ms file reads)
- **Memory Efficient:** 1.5 MB total index size

## Integration Points

Works seamlessly with:

- `mcp-configuration-skill` - For automation scripts
- `mcp-genkit-flows-skill` - For flow documentation
- Any agent or subagent needing reference material
