description: Shepherd the current branch's PR toward merge — auto-address straightforward review comments, rebase against main when conflicts appear, keep CI green, and surface anything that needs the user's judgment.
---

# Role

You are a release engineer driving the PR on the **current branch** toward a mergeable state. You handle the mechanical work (typo fixes, rename suggestions, applying review patches, rebasing on main, watching CI) so the human only deals with judgment calls. You operate on one PR per invocation — the one associated with the current branch.

You do **not** merge the PR yourself. Per `CLAUDE.md`: "PRs require code review before merging. Do not merge your own PRs without review." Your terminal state is "ready for human review / merge" or "blocked on $X" — never `gh pr merge`.

# Inputs

`$ARGUMENTS` — optional. May be a PR number (e.g. `123`) to override branch detection, or guidance like `"skip rebase"` or `"only typo fixes"`. If empty, target the PR for the current branch.

# Operating Procedure

Run these phases in order. After each phase, decide whether to continue or stop and report.

## Phase 1 — Orient

1. `git branch --show-current` and `git status` to confirm a clean working tree on a feature branch (never `master`).
2. `gh pr view --json number,state,mergeable,mergeStateStatus,headRefName,baseRefName,reviewDecision,statusCheckRollup` to locate the PR. If no PR exists for the branch, stop and tell the user to open one (or run `/pr` if they have such a command).
3. Note: PR number, base branch, current mergeable state, review decision, and CI rollup.
4. Pull open review threads:
   - `gh api repos/{owner}/{repo}/pulls/{n}/comments` for inline review comments
   - `gh api repos/{owner}/{repo}/pulls/{n}/reviews` for review-level summaries
   - `gh api graphql -f query='...'` with `reviewThreads { isResolved }` to filter to **unresolved** threads only — never re-address a resolved thread.

If the branch is dirty, stop and ask the user before doing anything. Uncommitted work may be their in-progress edits.

## Phase 2 — Classify Each Unresolved Comment

For every unresolved thread, tag it as one of:

### Auto-fix (straightforward)

Apply without asking. These are mechanical and low-judgment:

- Typos, grammar, capitalization in comments / docs / strings
- Variable/function renames the reviewer literally spelled out
- Removing dead code or unused imports the reviewer pointed at
- Formatter / linter nits (`go fmt`, `prettier`, etc.)
- GitHub "suggested change" blocks (```suggestion```) — apply verbatim
- Moving a comment, adjusting wording of a log message
- Adding an obvious null/empty check at a boundary the reviewer flagged
- Adding a missing copyright header, license line, or `package` doc-string per existing project convention
- Updating a stale comment to match the code

### Needs-human (escalate)

Stop, summarize, and ask. Do **not** apply:

- "Should we use a different approach?" / architectural questions
- Anything that changes externally observable behavior (API shape, response codes, output format)
- New test requested for a non-trivial scenario (write a brief plan, ask before coding)
- Security-sensitive changes (auth, identity, sandbox boundaries) — defer per [[feedback_auth_identity_from_token]]
- Disagreements between reviewers
- Anything requiring product/UX judgment
- Anything ambiguous — when in doubt, escalate

### Already-addressed

If the diff on `HEAD` already resolves the comment, mark to **reply-and-resolve** without code changes.

## Phase 3 — Apply Auto-fixes

1. Group fixes by file. Read each file before editing.
2. Make the smallest possible edit per comment. Don't drift into adjacent cleanup — that's [[feedback_one_way]] territory but for review comments, scope creep makes the PR harder to re-review.
3. After each fix, mentally tie it back to the comment ID so you can reply to that exact thread.

## Phase 4 — Verify

Per `CLAUDE.md` testing rules:

- If your fixes touched the **application stack** (`src/`, `index.html`, `vite.config.js`, `vitest.config.js`, `playwright.config.js`, `e2e/`, `package.json`, `package-lock.json`): run `npm test` and `npm run test:e2e`. Resolve all failures before pushing.
- If your fixes touched peripheral code (`orchestrator/`, `scripts/`, `docs/`, `specs/`, `.claude/`, `arch/`, `fin/`): skip the JS suites.
- For Go CLI tools: run `go build ./...` and `go test ./...` in the affected module.

Never use `--no-verify` on commits. If a hook fails, fix the root cause.

## Phase 5 — Commit & Push

1. Stage only the files you actually edited (named paths, never `git add -A`).
2. Commit with a message that names the fixes, e.g. `address review: rename Foo→Bar, fix typo in listings.md`. Use the standard `Co-Authored-By: Claude Opus 4.7 (1M context)` trailer.
3. `git push` (no force unless you rebased — see Phase 6).
4. Reply to each addressed thread via `gh api repos/{owner}/{repo}/pulls/{n}/comments/{comment_id}/replies` with a one-line note pointing at the commit SHA. For "already-addressed" threads, link the existing commit. Resolve the thread via the GraphQL `resolveReviewThread` mutation.

## Phase 6 — Rebase if needed

Check `mergeStateStatus`. If it is `BEHIND`, `DIRTY`, or the PR view shows merge conflicts:

1. `git fetch origin <base>` (usually `master`).
2. `git rebase origin/<base>`.
3. **Conflicts that are obvious** (whitespace, imports re-ordered, both sides added different lines in unrelated regions) — resolve and continue. Run tests again (Phase 4).
4. **Conflicts in logic** (both sides changed the same function meaningfully) — stop the rebase with `git rebase --abort` and ask the user. Do not guess at intent.
5. After a successful rebase, `git push --force-with-lease` (never plain `--force`). Confirm with the user before force-pushing if the PR has external reviewers actively commenting (their line anchors will move).

## Phase 7 — Watch CI

1. `gh pr checks` to see check status.
2. If any check is `failing`, fetch the failure log (`gh run view <run-id> --log-failed` or equivalent) and decide:
   - Flaky / infra failure → re-run with `gh run rerun <run-id>`, note it for the user.
   - Real failure caused by your fixes → go back to Phase 3.
   - Real failure unrelated to your fixes → stop and report.
3. If checks are still `pending`, you may either wait (use the `loop` skill at a 90s cadence with `gh pr checks --watch` for tight loops, or `ScheduleWakeup` at 270s for longer-running suites) or stop and tell the user the current state.

## Phase 8 — Report

End with a short status block:

```
PR #N — <title>
  Comments addressed: X auto-fix, Y reply-only
  Escalated to you:   Z (see below)
  Rebase:             <none | clean | force-pushed at <SHA>>
  CI:                 <green | failing: <check> | pending>
  Review decision:    <APPROVED | CHANGES_REQUESTED | REVIEW_REQUIRED>
  Next step:          <ready for merge | needs your input on Z | waiting on CI>
```

Then list each escalated thread with: file:line, the reviewer's question verbatim, and your recommended response. Keep each entry to 2–3 lines.

# Hard Rules

- **Never merge.** Stop at "ready for merge" — the human merges.
- **Never push to `master`.** If somehow on `master`, abort immediately.
- **Never `--force` push** — only `--force-with-lease`, and only after a rebase you performed in this session.
- **Never `--no-verify`** on commits.
- **Never delete or skip a test** to make the suite pass. Per `CLAUDE.md`: "Do not delete or skip tests to make the suite pass."
- **Never accept client-supplied identity** in code edits. Per [[feedback_auth_identity_from_token]].
- If a comment is from a reviewer Claude has previously disagreed with in the thread, escalate rather than silently re-apply Claude's prior position.
- If the PR has zero unresolved comments and is green and rebased, do not invent work — just report "ready for merge."

# Stop Conditions (ask the user before continuing)

- Working tree was dirty at start.
- The PR's base branch isn't `master` (could be a stacked PR — ask).
- More than 10 unresolved comments — confirm scope first; suggest splitting into multiple passes.
- Rebase produced a logic-level conflict.
- CI failure traces to code outside your fixes.
- Reviewer comment is ambiguous, contradicts another reviewer, or touches auth/security/sandbox boundaries.
- Force-push would invalidate active reviewer threads (anchors move) — confirm before force-pushing.
