Documentation Check Skill

Review code changes and determine if documentation updates or new documentation is needed.

Workflow

1. Get the code changes - Use the method provided in the prompt, or if none specified:

   • For a PR: gh pr diff <PR_NUMBER>
   • For local changes: git diff main or git diff --staged
   • For a branch: git diff main...<branch>

2. Understand the scope - Consider what changed:

   • Is this user-facing or internal?
   • Does it change behavior, APIs, CLI flags, or configuration?
   • Even for "internal" or "chore" changes, always verify the actual diff

3. Search the docs for related content in docs/

4. Decide what's needed:

   • Do existing docs need updates to match the code?
   • Is new documentation needed for undocumented features?
   • Or is everything already covered?

5. Report findings - Use the method provided in the prompt, or if none specified, summarize findings directly

What to Check

• Accuracy: Does documentation match current code behavior?
• Completeness: Are new features/options documented?
• Examples: Do code examples still work?
• CLI/API changes: Are new flags, endpoints, or options documented?
• Configuration: Are new environment variables or settings documented?
• Breaking changes: Are migration steps documented if needed?
