A practical Codex workflow: from issue to tested patch

Tutorial · 1 min read

Terms in this guide: Acceptance criteria · Verification

Reliable agent-assisted work is a sequence of small decisions. This workflow keeps the request, investigation, implementation, and evidence connected so the final patch is easier to trust.

1. Translate the issue into behavior

Write the current behavior, desired behavior, and conditions that trigger the problem. Separate observed facts from guesses about the cause.

2. Inspect before editing

Ask Codex to locate the relevant path, read nearby tests and instructions, and present the smallest plausible plan. A plan is useful when it makes scope and assumptions visible.

3. Implement and verify

Make the focused change, add a test when it protects meaningful behavior, and run checks in increasing scope. Review the final diff for accidental churn before recording the result.

  • Focused reproduction or test passes.
  • Related tests still pass.
  • The diff contains only intended files.
  • The summary names any check that could not run.
