jackin-merge-pr

Sequence the jackin❯ pre-merge gates fail-closed, retire the roadmap item into docs, then squash-merge. Reuses the .github/ agent rules (auto-loaded) and PULL_REQUESTS.md — sequences them, never restates them.

When to use

• Operator runs jackin-merge-pr [<PR>] to merge a jackin❯ PR (defaults to the current branch's PR).

When NOT to use

• Opening or iterating a PR → jackin-create-pr / jackin-propose.

Arguments

• --no-poll — do not wait on pending CI; stop and report instead.
• --admin <check> — authorize bypassing one named failing check (still needs the high-blast-radius confirm).

Red flags — STOP

• No clear authorization for this PR and it is high-blast-radius → STOP, confirm first.
• Any required CI check failing → STOP (no --admin bypass without --admin <check> + confirm).
• Roadmap item not retired / not status-moved when the PR ships or advances it → STOP, fix first.

Process

1. Resolve PR. Current branch's PR or the arg. Read gh pr view and gh pr diff.
2. Blast-radius classify. High if the diff touches a versioned schema, auth/security surface, .github/workflows/**, or needs a force-push / --admin. High → pause for one explicit confirm. Normal → proceed (invoking the skill is the go).
3. CI gate. gh pr checks <PR>: if pending, poll until green (unless --no-poll); if any check fails, STOP. Trust CI — which runs cargo xtask schema-check plus the test/clippy/fmt jobs — no local re-run.
4. Roadmap retirement. Does this PR ship the last piece of its roadmap item?
   • Yes → [bin] cargo xtask roadmap retire <slug> --plan prints the worklist: the page content, every inbound link (grep <slug>), and the meta.json entry. [agent] Do the judgment moves — operator detail → guides//commands/, design detail → reference/, write the ## Completed bullet in roadmap/index.mdx, repoint inbound links; commit docs:. [bin] cargo xtask roadmap retire <slug> --apply removes the meta.json entry, deletes the .mdx, runs the audit, and fails if any inbound link still points at the dead slug. Run the bun docs gate; push.
   • Partial → cargo xtask roadmap retire <slug> --partial sets **Status**: Partially implemented and keeps the page; name the remaining phases; commit; push.
5. Metadata reconcile. Title/body match the final diff? Squash writes the title verbatim into history. Fix via gh pr edit if stale; surface the change in your reply.
6. Squash-merge. Build a body file (prose summary, no checklists), append trailers via cargo run -p jackin-pr-trailers -- --body-file, then gh pr merge <PR> --squash --body-file. Confirm the title carries (#N).
7. Report. Merged SHA and what retirement did.

Common mistakes

• Carrying a prior session's "just merge everything" as authorization — it does not carry forward.
• Merging on pending/failing CI, or --admin-bypassing without explicit per-check opt-in.
• Leaving a Status: Resolved roadmap page instead of retiring it into docs.
• Squash title missing the (#N) suffix or the DCO / Co-authored-by trailers.

Tooling

Bundles jackin-pr-trailers. cargo xtask roadmap retire <slug> --plan gives the agent the retirement worklist; --apply does the mechanical removal + audit and fails on a dangling link; --partial sets the Status. The content moves themselves are the agent's judgment. CI runs cargo xtask schema-check (the 5-artifact gate); this skill only reads its result.
