Goals

• Ensure the PR is conflict-free with main.
• Keep CI green and fix failures when they occur.
• Squash-merge the PR once checks pass.
• Do not yield to the user until the PR is merged; keep the watcher loop running unless blocked.
• No need to delete remote branches after merge; the repo auto-deletes head branches.

Preconditions

• gh CLI is authenticated.
• You are on the PR branch with a clean working tree.

Steps

1. Locate the PR for the current branch.
2. Confirm the full validation suite is green locally:

   go build ./...
   go test ./... -count=1
   go vet ./...
   test -z "$(gofmt -l .)"
   

3. If the working tree has uncommitted changes, commit with the commit skill and push with the push skill before proceeding.
4. Check mergeability and conflicts against main.
5. If conflicts exist, use the pull skill to fetch/merge origin/main and resolve conflicts, then use the push skill to publish the updated branch.
6. If a .github/workflows/*codex* workflow exists, ensure Codex review comments are acknowledged and any required fixes are handled before merging. Otherwise, skip the Codex review wait.
7. Watch checks until complete.
8. If checks fail, pull logs, fix the issue, commit with the commit skill, push with the push skill, and re-run checks.
9. When all checks are green and review feedback is addressed, squash-merge and delete the branch using the PR title/body for the merge subject/body.
10. Context guard: Before implementing review feedback, confirm it does not conflict with the user's stated intent or task context. If it conflicts, respond inline with a justification and ask the user before changing code.
11. Pushback template: When disagreeing, reply inline with: acknowledge + rationale + offer alternative.
12. Ambiguity gate: When ambiguity blocks progress, use the clarification flow (assign PR to current GH user, mention them, wait for response). Do not implement until ambiguity is resolved.
    • If you are confident you know better than the reviewer, you may proceed without asking the user, but reply inline with your rationale.
13. Per-comment mode: For each review comment, choose one of: accept, clarify, or push back. Reply inline (or in the issue thread for Codex reviews) stating the mode before changing code.
14. Reply before change: Always respond with intended action before pushing code changes (inline for review comments, issue thread for Codex reviews).

Commands

# Ensure branch and PR context
branch=$(git branch --show-current)
pr_number=$(gh pr view --json number -q .number)
pr_title=$(gh pr view --json title -q .title)
pr_body=$(gh pr view --json body -q .body)

# Check mergeability and conflicts
mergeable=$(gh pr view --json mergeable -q .mergeable)

if [ "$mergeable" = "CONFLICTING" ]; then
  # Run the `pull` skill to handle fetch + merge + conflict resolution.
  # Then run the `push` skill to publish the updated branch.
fi

# Watch checks
if ! gh pr checks --watch; then
  gh pr checks
  # Identify failing run and inspect logs
  # gh run list --branch "$branch"
  # gh run view <run-id> --log
  exit 1
fi

# Squash-merge (remote branches auto-delete on merge in this repo)
gh pr merge --squash --subject "$pr_title" --body "$pr_body"

Async Watch Helper

Preferred: use the asyncio watcher to monitor review comments, CI, and head updates in parallel:

python3 .codex/skills/land/land_watch.py

Exit codes:

• 2: Review comments detected (address feedback)
• 3: CI checks failed
• 4: PR head updated (autofix commit detected)

Failure Handling

• If checks fail, pull details with gh pr checks and gh run view --log, then fix locally, commit with the commit skill, push with the push skill, and re-run the watch.
• Use judgment to identify flaky failures. If a failure is a flake (e.g., a timeout on only one platform), you may proceed without fixing it.
• If CI pushes an auto-fix commit (authored by GitHub Actions), it does not trigger a fresh CI run. Detect the updated PR head, pull locally, merge origin/main if needed, add a real author commit, and force-push to retrigger CI, then restart the checks loop.
• If mergeability is UNKNOWN, wait and re-check.
• Do not merge while review comments (human or Codex review) are outstanding.

Review Handling

• Human review comments are blocking and must be addressed (responded to and resolved) before requesting a new review or merging.
• If multiple reviewers comment in the same thread, respond to each comment (batching is fine) before closing the thread.
• Fetch review comments via gh api and reply with a prefixed comment.
• Use review comment endpoints (not issue comments) to find inline feedback:
  • List PR review comments:

    gh api repos/{owner}/{repo}/pulls/<pr_number>/comments
    

  • PR issue comments (top-level discussion):

    gh api repos/{owner}/{repo}/issues/<pr_number>/comments
    

  • Reply to a specific review comment:

    gh api -X POST /repos/{owner}/{repo}/pulls/<pr_number>/comments \
      -f body='[codex] <response>' -F in_reply_to=<comment_id>
    

• in_reply_to must be the numeric review comment id (e.g., 2710521800), not the GraphQL node id (e.g., PRRC_...), and the endpoint must include the PR number (/pulls/<pr_number>/comments).
• All GitHub comments generated by this agent must be prefixed with [codex].
• If feedback requires changes:
  • Reply with intended fixes ([codex] ...) as an inline reply to the original review comment.
  • Implement fixes, commit, push.
  • Reply with the fix details and commit sha in the same place.

Scope + PR Metadata

• The PR title and description should reflect the full scope of the change, not just the most recent fix.
• If review feedback expands scope, decide whether to include it now or defer it. You can accept, defer, or decline feedback.
• Correctness issues raised in review comments should be addressed. If you plan to defer or decline a correctness concern, validate first and explain why the concern does not apply.
• Classify each review comment as one of: correctness, design, style, clarification, scope.
• Prefer a single consolidated "review addressed" root-level comment after a batch of fixes instead of many small updates.
