This one turns Claude into a relentless interviewer for your design decisions. Instead of just nodding along, it walks through every branch of your plan, asking pointed questions about user flows, edge cases, and dependencies until you've actually thought things through. What's smart is it checks your codebase and existing components first before asking, so you're not rehashing stuff that's already decided. Each question comes with a recommended answer, which helps when you're stuck. Use it when you've got a half-baked idea that needs stress-testing or when you know there are gaps in your thinking but can't pinpoint them. It's like having a skeptical coworker who actually cares about helping you ship something solid.
