FAQPage Schema
How do I get an independent second opinion on code changes during review?

Adversarial code review analyzes your diffs to actively challenge implementations and attempt to break the solution. This approach surfaces edge cases and gaps that standard review processes might miss, providing a brutally honest assessment of code changes.

What's the best way to challenge my implementation and find edge cases?

Adversarial code review analyzes your diffs to actively challenge implementations and attempt to break the solution. This approach surfaces edge cases and gaps that standard review processes might miss, providing a brutally honest assessment of code changes.

Do I need the Codex CLI installed to run an AI code review?

Yes, the Codex CLI must be installed and accessible in the shell to execute this AI-assisted code review. The CLI processes your code context and diffs to generate the independent review output within your development workflow.

Can I use consult mode for follow-up questions after a code review?

Yes, consult mode provides session continuity for iterative refinement after an initial code review. You can ask follow-up questions to further analyze diffs and refine the proposed alternatives or address surfaced edge cases.

How do I integrate an AI second opinion into my development workflow?

You integrate an AI second opinion into your development workflow by using a CLI tool that surfaces guidance directly within your existing environment. This allows you to obtain independent reviews on code changes seamlessly as you build and test.
