PullPlane turns a collaborative card into the working brief for Codex, gives the run an isolated repository workspace, and keeps the resulting change inside the team's normal branch and pull-request review flow.
Codex inside the delivery workflow
A Codex run reads the card brief, checks out the connected repository, and works on the card branch inside a dedicated sandbox. PullPlane surfaces the live terminal, changed files, git diff, preview when available, and pull request instead of reducing the result to a chat answer.
Workspace owners can configure Codex with an OpenAI API key or a connected ChatGPT subscription. The selected model and supported reasoning effort are chosen for the run.
Where Codex fits best
The focused-fix starter recipe uses Codex for a tightly scoped implementation, followed by a Reviewer pass. The research-build-review recipe also uses Codex after a Research agent has documented the code paths, risks, and recommended approach.
- Reproducible bugs with an explicit expected behavior
- Focused engineering changes with regression coverage
- Implementation after a separate evidence-gathering step
Review the artifact, not the agent label
Codex output remains a proposal. Review the changed code, test evidence, unresolved assumptions, and pull request checks before merging. PullPlane can add specialist QA and Security gates for projects that need those checks on matching card priorities.
