FAQPage Schema
How do I get an independent code review for my git diff?

To get an independent code review, run a CLI wrapper against your current git diff to perform a diff-based assessment with a pass/fail gate. This provides a brutally honest second opinion on your code changes before merging.

Can I run adversarial prompts to try to break my code automatically?

Yes, you can run adversarial prompts to try to break your code using a dedicated challenge mode. This mode executes adversarial challenges against your code changes to actively probe for weaknesses and potential failures.

Do I need the codex CLI installed to use this code assessment wrapper?

Yes, you need the codex CLI installed to use this code assessment wrapper. The tool requires the codex CLI to be present in your environment and also supports the Bash, Read, Write, Glob, Grep, and AskUserQuestion tools.

How does session continuity improve AI-assisted code consult feedback?

Session continuity improves AI-assisted code consult feedback by maintaining context across multiple interactions. This retained context allows the AI-assistant to provide higher quality follow-up answers during consult-style prompts.

What is the best way to challenge AI-generated code suggestions before merging?

The best way to challenge AI-generated code suggestions is to use an adversarial CLI wrapper to run challenge prompts. This provides an independent, brutally honest second opinion that actively tries to break the code changes before approval.
