Gotchas

  • Codex review is non-deterministic — same code with different invocations gets different priority orderings; pin model version when reproducibility matters.
  • Codex doesn't see staged-but-uncommitted changes by default — pass them explicitly via --include-staged or piped diff.
  • Diff-only review misses cross-file effects — a renamed function's callsite in another file isn't in the diff, so the rename's blast radius isn't surfaced.
  • Review output ranks by Codex's internal severity heuristic — not by user-defined priority; re-rank manually for project-specific concerns.
  • Whitespace-only diffs trigger reviews — pass --ignore-whitespace or you get noise.
  • Large diffs (>500 LOC) get summarized, not reviewed line-by-line — split into focused reviews per file group.
