Codex PR Review Loop

Overview

Run a 5-minute polling loop for PR review threads, act only when new review updates appear, fix issues found, commit+push, post a standalone @codex review PR comment, and repeat until Codex reports no major issues, then merge to remote main and pull locally.

Workflow (Loop)

Preconditions

1. PR already exists.
2. gh is authenticated.
3. You are allowed to push/merge as part of this explicit user-requested workflow.

Step 0: Identify PR

• Prefer current branch PR: gh pr view --json number.
• If ambiguous, ask for PR number.

Step 1: Poll review threads and PR issue comments

Run:

GH_OWNER=<owner>
GH_REPO=<repo>
PR_NUMBER=<number>
 
gh api graphql -f owner="$GH_OWNER" -f name="$GH_REPO" -F number=$PR_NUMBER -f query='query($owner:String!,$name:String!,$number:Int!){repository(owner:$owner,name:$name){pullRequest(number:$number){reviewThreads(first:100){nodes{isResolved path line originalLine comments(first:50){nodes{author{login} body createdAt reactions(content: THUMBS_UP){totalCount}}}}} comments(first:100){nodes{author{login} body createdAt reactions(content: THUMBS_UP){totalCount}}}}}}}'

Step 2: Wait for updates (repeat until update)

• Do not proceed unless review threads or PR issue comments have new updates since the last poll (new comments, new threads, or updated timestamps).
• If no updates are found, wait 5 minutes and poll again. Continue doing this automatically until updates appear.

Step 3: Decide

• If any review thread comment OR PR issue comment contains Codex Review: Didn't find any major issues (exact phrase) OR a thumbs-up signal:
• thumbs-up signal = comment body includes 👍 or :+1: OR reactions(content: THUMBS_UP).totalCount > 0
• You may merge to remote main, then pull locally. Proceed to Step 6.
• Else: treat updated review thread feedback as actionable. Proceed to Step 4.

Step 4: Fix bugs or requested changes

• Apply fixes in code.
• Add/adjust tests for regressions.
• Run relevant verification commands.
• Commit changes locally.
• Push to update the PR.

Step 5: Reply and wait

• Post a separate PR issue comment (not a thread reply) with exactly @codex review.
• Use: gh pr comment <PR_NUMBER> --body "@codex review"
• After replying, immediately return to Step 2 (wait 5 minutes, poll again until updates appear).

Step 6: Merge and sync

• Merge PR to main on remote (e.g., gh pr merge --merge or project-required strategy).
• Pull latest main locally.

Guardrails

• Do not merge until review thread content or PR issue comments explicitly include: Codex Review: Didn't find any major issues or a thumbs-up signal (see Step 3).
• Do not take any action (fix/respond/merge) unless review threads have new updates since the last poll.
• If no updates are found, you MUST keep waiting in 5-minute increments until updates appear.
• Always run tests appropriate to the change before pushing.
• Follow repo rules (e.g., no git push unless this skill is explicitly requested).
• If merging/pushing requires confirmation in the current environment, ask for explicit confirmation.
