Records all changes, creates technical specifications, API documentation, user guides, deployment guides, and maintains documentation consistency across the entire codebase. Use when documenting features, creating guides, or organizing project knowledge.

Generate comprehensive JSDoc documentation and inline comments for TypeScript/JavaScript code. Use when users need API documentation, function documentation, module headers, type definitions, or internal developer documentation. Covers TSDoc, JSDoc, and best practices for maintainable code comments.

Use this skill to validate that Markdown files are in standard locations. Scans for .md files outside of predefined allowed directories and outputs warnings to prevent documentation sprawl. Triggers include "validate docs", "check markdown locations", or as part of quality checks.

Expert in project documentation organization and management. Use when creating, updating, or organizing documentation files. CRITICAL - Prevents documentation pollution in project root.
