name: create-documentation description: Generate markdown documentation for a module or feature

You are creating proper markdown documentation for a module or feature in the library.

Read WRITING_STYLE.md first for tone, formatting conventions, and anti-patterns to avoid.

Your Task

1. Identify the scope - Based on the conversation context, determine what module, feature, or file needs documentation. Ask the user if unclear.
2. Read the source code - Understand the public API, types, and behavior
3. Read existing docs - Check content/docs/ for documentation to update
4. Write comprehensive documentation - Create or update MDX docs

Documentation Structure

This project uses Fumadocs for documentation. All docs live in content/docs/ as MDX files.

Where to Put Documentation

| Type | Location | When to use | | ------------------- | ----------------------------------- | ---------------------------------------------------- | | API Reference | content/docs/api/<class>.mdx | Documenting a class like PDF, PDFPage, PDFForm | | Feature Guide | content/docs/guides/<feature>.mdx | How-to guides for features (forms, signatures, etc.) | | Concept | content/docs/concepts/<topic>.mdx | Explaining PDF concepts (structure, objects, etc.) | | Getting Started | content/docs/getting-started/ | Installation and first steps |

Navigation (meta.json)

Each directory has a meta.json that controls navigation order:

{
  "title": "API Reference",
  "pages": [
    "index",
    "---Classes---",
    "pdf",
    "pdf-page",
    "pdf-form",
    "annotations",
    "---Other---",
    "errors"
  ]
}

• Use ---Label--- for section dividers
• Order determines sidebar appearance

<Callout type="error">Error/danger message</Callout>

Guidelines

See WRITING_STYLE.md for complete guidelines. Key points:

• Tone: Direct, second-person, no emojis
• Examples: Progressive complexity, all must be valid TypeScript
• Tables: Use Sharp-style nested parameter tables (see WRITING_STYLE.md)
• Callouts: Use sparingly for warnings, beta features, security
• Cross-references: Link related docs, add "See Also" sections
• Navigation: Update meta.json when adding new pages

Process

1. Explore the code - Read source files to understand the API
2. Check existing docs - Look in content/docs/ for related pages
3. Identify the audience - Who will read this? What do they need?
4. Draft the structure - Outline sections before writing
5. Write content - Fill in each section with examples
6. Update navigation - Add to relevant meta.json if new page
7. Add cross-references - Link from related docs

Begin

Analyze the conversation context to determine the documentation scope, read the relevant source code, and create comprehensive MDX documentation in content/docs/.
