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.
