AG Kit

AG Kit is a comprehensive toolkit for expanding AI coding assistants with 47 skills, 20 specialist agents, and 13 production-ready workflows installable via CLI. It packages playbooks, guardrails, and domain expertise so AI agents work as a coordinated team rather than isolated chat windows. The toolkit includes specialist agents for frontend, backend, security, database, and mobile development, along with guided slash commands for brainstorming, planning, coding, testing, and deployment.

Designed for teams shipping features faster while maintaining safety, AG Kit uses merge-aware updates with three-way conflict detection and backups to preserve local changes during upgrades. Built for Google Antigravity as the primary runtime, it provides a managed workspace contract with persistent memory, orchestration, and a native safety hook that prevents destructive filesystem operations while allowing normal project cleanup.
