Purpose
Turn “the code seems done” into a reproducible release decision while preserving unrelated work and repository governance.
When it fires
- A change is ready to commit, push, open for review, merge, or deploy.
- The user asks for release, landing, PR, or Git/Vercel operations.
- A stale or failing PR needs evidence-based disposition.
Inputs
- Repository instructions, branch policy, and required checks.
- Exact diff, test results, review findings, deployment state, and rollback path.
- User authority for commit, push, merge, production, publication, and cleanup.
Workflow
- Verify path, repository root, origin, branch, and working-tree ownership.
- Inspect the complete diff and exclude unrelated user changes.
- Run proportionate tests, lint/type gates, secret scan, and diff checks.
- Use a preview deployment for web changes when the repository supports it.
- Record independent review findings and resolve blockers.
- Confirm mergeability, required checks, release notes, rollback, and post-merge monitoring.
- Execute only the authorized Git or deployment action; never force-push or rewrite shared history by default.
Output contract
Return revision, diff scope, gates and results, review status, preview/production state, known limitations, rollback, action taken, and remaining human decisions.
Tools & MCP
Use non-interactive Git, the repository’s CI, secret scanner, and hosting connector. Preserve dirty worktrees, avoid destructive reset/checkout commands, and stop session-owned servers.
Quality bar
- “Green” means required gates passed on the exact head revision.
- Skipped or unavailable checks are explicit.
- A successful preview is not called a production release.
- Merge or deployment follows branch protection and human authority.
Example
Input: “Land PR 21 if it is ready.”
Good output: verify the exact head, required CI and security reviews, run release smoke tests against the preview, resolve comments, merge using repository policy, verify production, and retain a rollback revision.
