Codex can help inspect a change, trace affected paths, and describe potential problems. A good review request defines the comparison, the properties that matter, and the level of evidence required for a finding.
Define the review surface
Name the branch, commit, pull request, or working-tree change you want reviewed. Add the context that the diff cannot show, such as a compatibility promise or a production incident the change is meant to prevent.
- Specify the exact change to compare.
- Call out security or data-integrity properties.
- Identify supported environments and versions.
- Ask for file and line references for every finding.
Separate evidence from speculation
Ask Codex to trace each candidate issue through the code path and to discard findings that depend on impossible states. Severity should follow the real impact and likelihood, not the vocabulary of the bug pattern.
Turn findings into decisions
Read each finding against the code, reproduce the behavior when practical, and decide whether the suggested fix protects the existing contract. After changes, rerun the focused checks and review the final diff.
- Can the triggering input reach this code?
- Does a guard already prevent the outcome?
- Would the fix introduce a compatibility break?
- Is the regression test tied to observable behavior?
