Can I ask general prompts about my repository state and keep session continuity?

Yes, you can ask general prompts about your repository state using consult mode, which provides quick guidance and maintains session continuity for follow-up questions.

How does a blunt AI code review challenge my security assumptions?

A blunt AI code review challenges security assumptions by independently evaluating your project diffs and adversarial prompts, providing an unbiased gate verdict rather than simple validation.
