Back to Seatbelt

Start with /seatbelt

Install with npx, latch the AI-built app you're shipping, then run your first check. Seatbelt sits next to your agent: a check as fast as your agent ships.

  1. 01Install tooling

    Node 22+. Wires the Seatbelt MCP into whichever agents you have (Cursor, Claude Code, Antigravity, and Codex) and installs the /seatbelt skill and commands where the agent supports it. Reload MCP and confirm Seatbelt shows connected or ask your agent.

  2. 02Latch your app

    Run inside the app you're shipping, not the monorepo. Creates .seatbelt/ so re-checks remember what changed. Say yes to the enforcement layer when offered.

  3. 03Run your first check

    You get a plain-English verdict, a report link, and a next move. Run /seatbelt fix to apply fixes, then re-run /seatbelt until you're cleared. Every command and MCP tool is on the Commands page.

Every command and MCP tool, with what each one does: Commands reference.
