second-opinion

Automated code reviews using an AI CLI are executed by running the Codex CLI in your project directory, selecting a review mode, and receiving independent pass/fail assessments with critical P1 findings in a verbatim output block.

Adversarial testing in code review is a challenge mode that attempts to break edge cases in your code. It works by applying adversarial prompts to your diffs, identifying vulnerabilities, and presenting critical findings for security-focused audits.

No, you do not need an API key to use Codex CLI for independent code review. You must authenticate using a ChatGPT Business subscription, which enforces safety and ensures verifiable outputs without API key configuration.

Yes, you can use AI code review for pre-merge diffs and security audits. The tool operates in review, challenge, or consult modes, applying structured analysis and adversarial prompts to diverse repositories for educational exploration or security-focused audits.

The best way to get a second opinion on code from a different LLM is using cross-LLM review tools. This Skill automates independent, multi-turn consults with session persistence via Codex CLI, providing structured feedback and P1 findings.

The primary limitation of using ChatGPT Business authentication for code review is the strict requirement for a ChatGPT Business subscription. It never uses standard API keys, meaning access is blocked without this specific subscription type.
