Second opinion

A review by another model

A short command that has Codex review your code changes without touching them. It comes from a different model family than Claude, so it can catch what Claude misses. Reviews like this tend to find a lot, so every finding gets rated for how likely it is and how bad it would be. Your AI checks each one against the code, fixes what matters and leaves the small stuff alone.

Finding	Likelihood x impact	Action
Retry can charge a customer twice	6 x 9	Fixed
Empty search crashes the export page	5 x 4	Fixed
Very long names wrap badly on a receipt	2 x 2	Left alone, noted

Example of what your AI reports back. Fix it if likelihood x impact is 10 or more, or if impact is 8 or more. Findings are invented.
