Update docs

Update Documentation

Update human-edited markdown documentation files after completing a piece of work.

When to Use

Only when the user explicitly requests documentation updates (e.g., "update the docs", "sync documentation", "refresh the readme").

Process

1. Ask what to review - Before analyzing code, ask the user:

   • Uncommitted changes only (staged + unstaged)
   • Committed changes (all commits on current branch)
   • Both uncommitted and committed changes
   • Whole repo (review entire codebase, not just recent changes)

   For uncommitted/committed/both:

   • Use git diff for uncommitted changes
   • For committed changes, review all commits unique to the current branch (use git log main..HEAD or similar)
   • Focus documentation updates on what changed

   For "Whole repo" option:

   • Explore the codebase structure (key directories, main files, entry points)
   • Identify features, APIs, and components
   • Compare existing documentation against actual code
   • Look for undocumented features, outdated information, or missing sections
   • This is useful for documentation audits or when docs have drifted significantly from code

2. Identify documentation files - Search for:

   • README.md files (root and nested)
   • docs/ or documentation/ folders
   • agents.md, claude.md, or similar project-specific docs
   • Any other .md files that appear to be human-edited

3. Filter out auto-generated and special files - Skip:

   • Auto-generated documentation (look for generation comments/headers)
   • LICENSE, LICENSE.md
   • CONTRIBUTING.md
   • CHANGELOG.md, HISTORY.md
   • CODE_OF_CONDUCT.md
   • Files with "auto-generated" or "do not edit" markers

   If the user wants these files updated, ask for explicit confirmation first.

4. Review existing conventions - Before making changes:

   • Read the existing documentation style and formatting
   • Match the tone (formal vs casual)
   • Follow existing heading structures
   • Preserve any existing patterns for code examples, links, etc.

5. If no documentation exists - Work with the user to initialize:

   • Ask what documentation they want to create
   • Suggest a basic structure based on the project type
   • Start minimal and expand based on feedback

6. Make targeted updates:

   • For change-based reviews: only update sections relevant to the changes
   • For whole repo reviews: address gaps, outdated info, and missing documentation
   • Don't rewrite entire documents unnecessarily
   • Add new sections for undocumented features
   • Update existing sections if behavior differs from docs
   • Remove outdated information

What to Document

Based on the work completed, consider updating:

• Features/Usage: New functionality, how to use it, examples
• Installation/Setup: New dependencies, configuration options
• API Reference: New endpoints, functions, parameters
• Architecture: Structural changes, new components
• Examples: Working code snippets demonstrating changes

Guidelines

• Keep documentation concise and scannable
• Use code blocks with appropriate language tags
• Prefer examples over lengthy explanations
• Link to related documentation rather than duplicating
• Maintain consistent formatting with existing docs
