description: Generate focused documentation for components, functions, APIs, and features
allowed-tools: Read, Grep, Glob, Write, Bash
argument-hint: "[what to document] [format: inline/api/guide/external]"

/document - Focused Documentation Generation

Triggers

• Documentation requests for specific components, functions, or features
• API documentation and reference material generation needs
• Code comment and inline documentation requirements
• User guide and technical documentation creation requests

Usage

/document [what to document - can specify inline comments, API docs, user guide, etc.]

Behavioral Flow

1. Analyze: Examine target component structure, interfaces, and functionality
2. Identify: Determine documentation requirements and target audience context
3. Generate: Create appropriate documentation content
4. Format: Apply consistent structure and organizational patterns
5. Integrate: Ensure compatibility with existing project documentation ecosystem

Key behaviors:
- Code structure analysis with API extraction and usage pattern identification
- Multi-format documentation generation (inline, external, API reference, guides)
- Consistent formatting and cross-reference integration
- Project-specific documentation patterns for React and Phoenix

Tool Coordination

• Read: Component analysis and existing documentation review
• Grep: Reference extraction and pattern identification
• Write: Documentation file creation with proper formatting
• Glob: Multi-file documentation projects and organization
• Bash (psql cli): Database structure analysis for data model documentation

Key Patterns

• Inline Documentation: Code analysis → JSDoc/docstring generation → inline comments
• API Documentation: Interface extraction → reference material → usage examples
• User Guides: Feature analysis → tutorial content → implementation guidance
• External Docs: Component overview → detailed specifications → integration instructions

Examples

Inline Code Documentation

/document src/auth/login.js with inline JSDoc comments
# Generates JSDoc comments with parameter and return descriptions
# Adds comprehensive inline documentation for functions and classes

API Reference Generation

/document GraphQL API endpoints in docs/api.md
# Creates comprehensive API documentation with endpoints and schemas
# Generates usage examples and integration guidelines

User Guide Creation

/document payment module user guide for docs/
# Creates user-focused documentation with practical examples
# Focuses on implementation patterns and common use cases

Component Documentation

/document React components with external docs in frontend/docs/
# Generates external documentation files for component library
# Includes props, usage examples, and integration patterns

Feature Documentation

/document user management feature in docs/features/
# Creates comprehensive feature documentation with workflows and usage
# Includes user stories, technical implementation, and integration points

Boundaries

Will:
- Generate focused documentation for specific components and features
- Create multiple documentation formats based on target audience needs
- Integrate with existing documentation ecosystems and maintain consistency

Will Not:
- Generate documentation without proper code analysis and context understanding
- Override existing documentation standards or project-specific conventions
- Create documentation that exposes sensitive implementation details
