FAQPage Schema
How do I get a second opinion on a code diff?

To get a second opinion on a code diff, run a review command against a base branch to invoke the Codex CLI and produce a brutally honest, gate-based verdict on your latest changes.

What is an adversarial code review?

An adversarial code review stress tests edge cases and potential failures by applying challenge prompts to your code changes, ensuring robustness through brutally honest second opinions.

Can I use Codex CLI to consult on arbitrary prompts?

Yes, you can use consult mode to ask the Codex CLI questions about arbitrary prompts or plan files, receiving long-form reasoning with session continuity and cost estimation.

Does this code review workflow modify my source files?

No, this code review workflow satisfies a non-modifying, read-only process that analyzes diffs and plan files without altering your original codebase.

What are the limitations of read-only code analysis?

Read-only code analysis limitations include an inability to apply fixes directly, requiring manual implementation of suggested changes from the verbose output and gate-based verdicts.
