# SpecRail PR Gate Use this skill before saying a PR is merge-ready. ## Steps 1. Collect current PR evidence. Prefer the read-only adapter when available: ```sh python3 checks/github_pr_evidence.py --github-repo <owner/repo> --pr <pr-number> --json > <evidence.json> ``` 2. Run the offline gate: ```sh python3 checks/pr_gate.py --repo . --evidence <evidence.json> --json ``` 3. Confirm evidence includes linked issue, current PR head SHA, CI/check rollup, review decision, review-thread resolution, merge state, and human merge authorization. 4. Interpret decisions precisely: - `allowed`: evidence satisfies the local merge-readiness policy. - `needs_human`: deterministic evidence passed, but a human gate is missing. - `blocked`: do not merge. 5. Report the evidence file path, decision, blockers, and stale or missing data. ## Boundaries - Do not merge from this skill. - Do not treat green CI alone as merge readiness. - Do not ignore unresolved review threads. - Do not replace maintainer final review or human merge authorization.
