Use Codex as a second set of eyes, not as an automatic security certification.
The practical workflow
Review the diff for incorrect assumptions, null handling, auth checks, data leakage, race conditions, missing tests and costly queries. Request findings ordered by severity with paths, reproduction steps and suggested minimal fixes. Check each finding yourself.
Copy-and-adapt prompt
Review this diff for actionable defects. Prioritize regressions, security and correctness. Cite file and line context, explain impact and a reproducible scenario. Do not flag style-only issues unless they cause a concrete problem.
Review checklist and limitations
A clean AI review does not replace integration tests, dependency scanning or professional security review for sensitive systems.
What to do next
Choose a small issue, document the baseline and verify the result with a real test. Continue with the other Codex guides in the navigation menu.
