Summary

Turns feature ideas into structured PRDs with a smart two-step flow: asks you 3-5 multiple choice questions about goals, scope, and target users, then generates a markdown doc with user stories, acceptance criteria, and functional requirements. Saves to tasks/prd-[feature-name].md so you can hand it off to whoever's building it. The user stories include a nice touch where UI changes automatically get a "verify in browser" acceptance criterion. It explicitly tells Claude not to start implementing, which is good because jumping straight to code without planning is how you end up rewriting everything. Best for greenfield features where you need to think through requirements before writing a line of code.
