50+ native tools across 12 categories: file operations (read, write, edit, glob), code search (grep, symbol search, AST queries), execution (shell, test runner, linter), git (status, diff, commit), web (search, fetch, API requests), AWS monitoring (CloudWatch, ECS, RDS, Lambda), browser automation (Playwright), knowledge (document chunking, vector search), and more. Each tool is a sandboxed Node.js function — fast, type-safe, and workspace-scoped.
