codex-bug-reproducer

Find likely software bugs in a codebase, rank concrete bug candidates, and prove or reject them with focused regression tests before proposing a fix. Also turn bug reports, stack traces, screenshots, failing behavior, support tickets, and regressions into minimal reproducible cases with red-to-green evidence. Use when Codex needs to hunt for unknown bugs, audit code for correctness defects, test suspicious edge cases, reproduce a reported failure, isolate root cause, or verify that an approved fix works without regressions. Always require explicit approval before creating reproduction files and separate approval before changing production code.
