documentation-generator

name	documentation-generator
description	Automatically generate documentation when user mentions needing API docs, README files, user guides, developer guides, or changelogs. Analyzes code and generates appropriate documentation based on context. Invoke when user mentions "document", "docs", "README", "API documentation", "guide", "changelog", or "how to document".

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

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 - PHPDoc/JSDoc for Drupal & WordPress
• README Template - Complete project README structure
• User Guide Template - End-user documentation
• Changelog Template - 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:

pip install zensical

Create new project:

zensical new my-documentation

Configuration (zensical.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:

# Local preview
zensical serve

# Production build
zensical build --clean

GitHub Actions deployment:

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

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:

1. **Category Name**
   - Sub-item 1
   - Sub-item 2

DO:

### Category Name

- Sub-item 1
- Sub-item 2

Use Headings for Section Titles

DON'T:

**Section Title:**
- Item 1
- Item 2

DO:

#### 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:

1. **Step Name**: Description
   - Detail 1
   - Detail 2

DO:

#### 1. Step Name

Description

- Detail 1
- Detail 2
