Based on SOC occupation classification
Babysit a GitHub pull request after creation by continuously polling review comments, CI checks/workflow runs, and mergeability state until the PR is merged/closed or user help is required. Diagnose failures, retry likely flaky failures up to 3 times, auto-fix/push branch-related issues when appropriate, and keep watching open PRs so fresh review feedback is surfaced promptly. Use when the user asks Codex to monitor a PR, watch CI, handle review comments, or keep an eye on failures and feedback on an open PR.

| description | Change size guidance (800 lines) |
Unless the change is mechanical the total number of changed lines should not exceed 800 lines. For complex logic changes the size should be under 500 lines.
If the change is larger, explain whether it can be split into reviewable stages and identify the smallest coherent stage to land first. Base the staging suggestion on the actual diff, dependencies, and affected call sites.
