AG KIT

AG Kit is an open-source engineering toolkit designed primarily for Google Antigravity agent workspaces. It installs a structured .agents environment containing rules, skills, workflows, specialist agents, and persistent memory. The toolkit provides intelligent routing across 20 role definitions and includes repeatable commands for planning, debugging, testing, deploying, and orchestration. MCP configuration guidance helps agents connect to external tools while preserving reviewable workspace settings. A native pre-tool safety gate blocks high-confidence destructive commands without interfering with normal project cleanup. Merge-aware updates preserve local changes, create backups, and support rollback. Built-in validation, doctor checks, regression tests, and reproducible manifests help teams maintain reliable agent configurations.
