<integration>
**Integration with Technical Writer Agent**:
- Uses this skill for documentation generation
- Ensures documentation quality
- Validates completeness

**Integration with Developer Agent**:

- Generates API documentation
- Creates inline documentation
- Updates docs with code changes
  </integration>

<best_practices>

1. **Extract from Code**: Use code as source of truth
2. **Include Examples**: Provide working examples
3. **Keep Updated**: Sync docs with code
4. **Clear Structure**: Organize logically
5. **User-Focused**: Write for users, not system

## Memory Protocol (MANDATORY)

**Before starting:**
Read `.claude/context/memory/learnings.md`

**After completing:**
- New pattern -> `.claude/context/memory/learnings.md`
- Issue found -> `.claude/context/memory/issues.md`
- Decision made -> `.claude/context/memory/decisions.md`

> ASSUME INTERRUPTION: If it's not in memory, it didn't happen.
