# Documentation Generator

Automatically generate documentation for code, APIs, and projects.

## Philosophy

Good documentation is as critical as good code.

### Core Beliefs

1. **Code Documents What, Docs Explain Why**: Documentation provides context code cannot
2. **Documentation Enables Adoption**: Well-documented code gets used, undocumented code gets replaced
3. **Up-to-Date Beats Comprehensive**: Better to have accurate basics than stale details
4. **Multiple Audiences Need Different Docs**: Users need guides, developers need API references

### Why Documentation Matters

- **Onboarding**: New team members get productive faster
- **Maintenance**: Future developers (including yourself) understand intent
- **Adoption**: Users can actually use your features
- **Professional Quality**: Documentation signals production-ready software

## When to Use This Skill

Activate this skill when the user:
- Says "I need to document this"
- Asks "how do I write docs for this API?"
- Mentions "README", "documentation", or "user guide"
- Shows code and asks "what docs should I write?"
- Says "need API documentation"
- Asks about changelog or release notes
- Mentions "developer guide" or "setup instructions"

## Decision Framework

Before generating documentation, determine:

### What Type of Documentation Is Needed?

1. **API Documentation** - Code interfaces, parameters, return values → PHPDoc/JSDoc
2. **User Guide** - End-user instructions, screenshots → Markdown guide
3. **Developer Documentation** - Setup, architecture, contributing → README + guides
4. **Changelog** - Release notes, version history → Keep a Changelog format
5. **Inline Documentation** - Code comments, function docs → Language-specific format
6. **Documentation Site** - Multi-page documentation with search and navigation → Zensical site

### Who Is the Audience?

- **Developers** - Technical details, code examples, architecture
- **End Users** - Simple language, step-by-step instructions, screenshots
- **Contributors** - Setup instructions, coding standards, PR process
- **Stakeholders** - High-level overview, features, roadmap

### What's the Scope?

- **Single function/class** → Inline PHPDoc/JSDoc
- **Module/component** → Component documentation
- **Feature** → User guide + API docs
- **Entire project** → README + developer guide + API reference
- **Release** → Changelog entry

### What Already Exists?

**Check for**:
- Existing README → Update vs. create new
- Existing API docs → Append vs. regenerate
- CHANGELOG.md → Add new entry vs. create file
- Documentation site → Match existing format

### What Level of Detail?

- **Minimal** - Function signature, brief description → Quick reference
- **Standard** - Parameters, return values, usage example → Full API docs
- **Comprehensive** - Architecture, examples, edge cases, troubleshooting → Complete guide

### Decision Tree

```
User requests documentation
    ↓
Identify documentation type
    ↓
Determine audience (dev/user/contributor)
    ↓
Check for existing docs
    ↓
Assess scope (function/module/project)
    ↓
Generate appropriate documentation
    ↓
Format for platform (CMS-specific if needed)
```

## Workflow

### 1. Determine Documentation Type

**API Documentation** - For code interfaces:
- Functions, methods, classes
- Parameters and return types
- Examples and usage

**README** - For project overview:
- Installation instructions
- Quick start guide
- Features and requirements

**User Guide** - For end users:
- How to use features
- Screenshots and examples
- Troubleshooting

**Developer Guide** - For contributors:
- Architecture overview
- Setup and development
- Coding standards

**Changelog** - For releases:
- Version history
- What changed
- Migration guides

### 2. Analyze the Code/Project

**For API Docs**:
- Scan function signatures
- Identify parameters and return types
- Find existing comments
- Detect dependencies

**For README**:
- Check for package managers (composer.json, package.json)
- Identify framework (Drupal, WordPress, etc.)
- Find entry points and main features

**For Guides**:
- Understand user workflows
- Identify key features
- Note prerequisites

## Documentation Templates

Complete templates are available for reference:

- **[API Documentation Templates](templates/api-docs.md)** - PHPDoc/JSDoc for Drupal & WordPress
- **[README Template](templates/readme.md)** - Complete project README structure
- **[User Guide Template](templates/user-guide.md)** - End-user documentation
- **[Changelog Template](templates/changelog.md)** - Version history (Keep a Changelog format)

Use these templates as starting points, customizing for the specific project needs.

## Documentation Site Generation

For comprehensive documentation sites, use **Zensical** - a modern static site generator from the creators of Material for MkDocs.

### When to Use Zensical

- **Multi-page documentation** - Organize docs across multiple pages
- **Search functionality** - Built-in search for documentation
- **Modern theming** - Professional appearance with customization
- **Navigation** - Organized navigation with sections and subsections
- **GitHub Pages deployment** - Automated deployment via GitHub Actions

### Zensical Setup

**Install:**
```bash
pip install zensical
```

**Create new project:**
```bash
zensical new my-documentation
```

**Configuration (`zensical.toml`):**
```toml
[project]
site_name = "Project Name"
site_description = "Brief description"
site_url = "https://yoursite.github.io/project/"
docs_dir = "docs"
site_dir = "site"

nav = [
  {"Home" = "index.md"},
  {"Getting Started" = [
    "installation.md",
    "quick-start.md"
  ]},
  {"API Reference" = "api/index.md"}
]

[project.theme]
variant = "modern"
```

**Build and serve:**
```bash
# Local preview
zensical serve

# Production build
zensical build --clean
```

**GitHub Actions deployment:**
```yaml
name: Deploy Documentation
on:
  push:
    branches: [main]
jobs:
  build:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v4
      - uses: actions/setup-python@v5
        with:
          python-version: '3.x'
      - run: pip install zensical
      - run: zensical build --clean
      - uses: actions/upload-pages-artifact@v4
        with:
          path: ./site
```

## Generation Strategy

### 1. Gather Information

Ask clarifying questions:
- "What documentation type do you need?"
- "Who is the audience? (developers, end users, admins?)"
- "What specific features should be documented?"

### 2. Analyze Code

For API docs:
- Read function signatures
- Extract existing comments
- Identify dependencies
- Find usage examples

### 3. Structure Document

Follow standard patterns:
- Overview/introduction
- Prerequisites
- Main content (organized logically)
- Examples
- Troubleshooting
- Resources

### 4. Add Examples

Include:
- Code examples
- Screenshots (placeholder references)
- Before/after comparisons
- Common use cases

## Integration with CMS Cultivator

This skill complements the `/docs-generate` slash command:

- **This Skill**: Automatically triggered during conversation
  - "How do I document this function?"
  - "Need docs for this API"
  - Quick single-function documentation

- **`/docs-generate` Command**: Explicit batch generation
  - Generate full project documentation
  - Create comprehensive README
  - Build complete user guides

## Quick Response Patterns

### For API Documentation

When user shows a class or function:

1. Identify the type (Drupal service, WordPress function, JS module)
2. Generate appropriate docblock format
3. Include:
   - Description of purpose
   - Parameter documentation
   - Return type documentation
   - Usage example in @code block
   - Related functions (@see tags)

### For README

When user asks for project documentation:

1. Scan project structure (composer.json, package.json)
2. Identify platform (Drupal/WordPress/standalone)
3. Generate sections in order:
   - Title and description
   - Features list
   - Requirements
   - Installation (Composer first)
   - Quick start example
   - Links to detailed docs

### For User Guides

When user needs end-user documentation:

1. Ask about target audience
2. Identify main workflows
3. Structure with:
   - Overview
   - Prerequisites checklist
   - Step-by-step instructions
   - Screenshots placeholders
   - Troubleshooting section
   - FAQs

### For Changelogs

When user needs version history:

1. Use Keep a Changelog format
2. Categories: Added, Changed, Deprecated, Removed, Fixed, Security
3. Include version numbers and dates
4. Link to GitHub comparisons

## Example Interactions

**Example 1: API documentation**
```
User: "I need to document this service class"
[Shows DataProcessor class]

Skill: "I'll generate API documentation for your DataProcessor service.
I see it has 3 public methods and uses dependency injection.
I'll create docblocks with:
- Class description with usage example
- Constructor documentation
- Method documentation with @param and @return
- @code examples for each method

[Generates documented code following Drupal standards]

This follows Drupal documentation standards. Each method includes
parameter types, return types, and usage examples."
```

**Example 2: README**
```
User: "Need a README for my custom module"

Skill: "I'll create a comprehensive README for your module.
Let me check the project structure...

I see:
- Drupal 10 module
- Composer-based
- Custom services and admin routes

I'll generate a README with:
- Installation via Composer
- Feature list
- Configuration steps
- API usage examples
- Links to extended docs

[Generates README.md]"
```

**Example 3: Changelog Entry**
```
User: "What should I add to CHANGELOG for this release?"

Skill: "Based on your recent commits, I'll generate a changelog entry
following Keep a Changelog format:

## [1.2.0] - 2025-01-15

### Added
- User profile export functionality (#234)
- Bulk operations support

### Changed
- Improved query performance (30% faster)

### Fixed
- Permission check on admin pages (#145)

Would you like me to add this to your CHANGELOG.md?"
```

## Best Practices

1. **Clear and Concise** - Write for your audience's level
2. **Examples** - Always include working code examples
3. **Up to Date** - Document current functionality, not planned features
4. **Structured** - Use consistent headings and format
5. **Searchable** - Include keywords users will search for
6. **Complete** - Cover common use cases and edge cases

## Platform-Specific Guidelines

### Drupal Documentation
- Use PHPDoc format with @param, @return, @throws
- Include @code examples in docblocks
- Document services with usage examples
- Reference related APIs with @see tags
- Follow Drupal API documentation standards

### WordPress Documentation
- Use PHPDoc with @since tags
- Document hooks and filters
- Include usage examples in docblocks
- Reference WordPress functions
- Follow WordPress inline documentation standards

### JavaScript Documentation
- Use JSDoc format
- Document parameters and return types
- Include examples
- Document React components with PropTypes
- Follow project-specific standards (ESDoc, TSDoc)

### Markdown Style for Zensical Documentation

When generating markdown documentation for Zensical sites (like this plugin's documentation), follow these guidelines for proper rendering:

#### Use Headings, Not Bold Lists

**DON'T:**
```markdown
1. **Category Name**
   - Sub-item 1
   - Sub-item 2
```

**DO:**
```markdown
### Category Name

- Sub-item 1
- Sub-item 2
```

#### Use Headings for Section Titles

**DON'T:**
```markdown
**Section Title:**
- Item 1
- Item 2
```

**DO:**
```markdown
#### Section Title

- Item 1
- Item 2
```

#### Heading Hierarchy

- `#` - Document title (once at top)
- `##` - Major sections
- `###` - Subsections
- `####` - Categories, steps, or sub-subsections

#### For Step-by-Step Instructions

**DON'T:**
```markdown
1. **Step Name**: Description
   - Detail 1
   - Detail 2
```

**DO:**
```markdown
#### 1. Step Name

Description

- Detail 1
- Detail 2
```

**Complete style guide:** See [Markdown Style Guide](../docs/reference/markdown-style-guide.md) for full details and examples.
