            Is all documentation still 100% accurate?

            INSTRUCTIONS:
            1. Fact-check all documentation against the current codebase
            2. Look for:
               - Outdated API references
               - Deprecated functions or components still documented
               - Missing documentation for new features
               - Incorrect code examples
               - Broken internal references
               - Configuration examples that no longer work
               - Documentation that contradicts actual implementation
            3. Update any inaccurate or outdated documentation
            4. Add documentation for significant undocumented features
            5. Ensure all code examples are valid and tested against current code

            Focus on these key areas:
            - docs/**/*.md (all documentation files)
            - CLAUDE.md (project guidelines)
            - README.md files throughout the repository
            - .claude/commands/*.md (Claude command documentation)

            Make changes directly to the documentation files as needed.
            DO NOT modify any source code files unless absolutely necessary for documentation accuracy.

            After making all changes, create a comprehensive PR message summary:
            1. Write a detailed PR body to /tmp/pr-body-${{ github.run_id }}.md in markdown format
            2. Include:
               - ## Summary section with bullet points of what was changed
               - ## Changes Made section with details organized by category
               - ## Review Notes section with any important context
            3. Be specific about which files were updated and why
            4. If no changes were needed, write a brief message stating documentation is up to date
