- Babysit PrOpenAIOfficialBabysit 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.
- Code ReviewOpenAIOfficialRun a final code review on a pull request
- Code Review TestingOpenAIOfficialTest authoring guidance
- Codex Pr BodyOpenAIOfficialUpdate the title and body of one or more pull requests.
- ImagegenOpenAIOfficialGenerate or edit raster images when the task benefits from AI-created bitmap visuals such as photos, illustrations, textures, sprites, mockups, or transparent-background cutouts. Use when Codex should create a brand-new image, transform an existing image, or derive visual variants from references, and the output should be a bitmap asset rather than repo-native code or vector.
- Openai DocsOpenAIOfficialUse for Codex models/pricing, scheduled tasks, skills, settings, setup, troubleshooting, customization, automations, and self-knowledge—including 'you,' 'your,' 'this app,' or 'this coding agent' when they refer to Codex—and for OpenAI APIs/products and ChatGPT Work. Also use for model choice/migration, prompting, SDKs, Responses, Realtime, agents, evals, and Chat/Work/Codex comparisons.
- Review AgentOpenAIOfficialPerform a read-only, defect-first review of a specified code change and return every actionable finding. Use when another agent delegates review of uncommitted changes, a base-branch diff, a commit, or custom review instructions.
- Skill CreatorOpenAIOfficialCreate or update a Codex skill with appropriately scoped instructions and any needed supporting resources.
- Skill InstallerOpenAIOfficialInstall Codex skills into $CODEX_HOME/skills from a curated list or a GitHub repo path. Use when a user asks to list installable skills, install a curated skill, or install a skill from another repo (including private repos).
- Test TuiOpenAIOfficialGuide for testing Codex TUI interactively
