The Deploy Agent takes the built project out of the sandbox and ships it. Its system prompt names the mandate: “Owner of the publish-and-deploy pipeline for a single project.” It runs a preflight production build, pushes the code to GitHub, creates or reuses the Vercel project, syncs environment variables, and polls the deployment to completion. When a build breaks, it applies up to three targeted fix iterations before asking you, and it keeps a cumulative deploy ledger so every release is accounted for. The result is your product live on its own URL, with the code in a repo you own. Projects ship to {slug}.product-os.app, or to a custom domain.

What it reads and produces

Reads: the built project in the sandbox; environment variables; the deployment target. Produces: a live production deployment on its own URL; a GitHub repo with your code; a cumulative deploy ledger.

​
Where it sits in the pipeline

Deploy is an on-demand action, not a stage: you trigger it whenever you want to ship, and you can redeploy as often as you like. It is the last agent in the chain, downstream of the Fullstack Builder that wrote the code and, ideally, a passing run from the QA Agent. The Orchestrator can also poll live deployment state directly with check_deploy_status, so you can ask about a release without triggering a new one. The sequence is deliberately defensive. check_recent_deploy runs first so the agent never deploys blind over an in-flight or just-finished release, and preflight_build runs the production build inside the sandbox before anything is pushed, so most failures are caught and fixed before they ever reach Vercel. For domains and deployment details beyond the agent itself, see deployments and domains.

​
Working with it

Run the QA Agent before you deploy. The Deploy Agent’s self-fix loop is scoped to build failures: it reads the Vercel build logs and repairs what breaks compilation, up to three iterations. It does not judge whether your signup flow works. A QA pass first means the thing that goes live is verified end to end, not just buildable.
