What problem does it solve? Teams at hackathons waste hours writing bloated product documents that nobody reads; this Skill turns an idea brief plus a short interview into a tight PRD that acts as the contract between the team and the clock. ## Core Features & Use Cases - Guided Interview: Asks only the questions the idea brief does not answer, one at a time, capped at six, covering demo user, core loop, demo moment, scale gate, constraints, and non-goals. - Five-Question PRD Structure: Produces PROBLEM, USER & CORE LOOP, DEMO NARRATIVE, SCOPE (MUST/SHOULD/CUT/NON-GOALS), and SUCCESS sections with strict traceability between demo beats and scope items. - QUICK and FULL Modes: Outputs a one-page PRD for small fast builds (≤24h, ≤2 builders) or a three-page FULL version, with vocabulary frozen so code, schema, UI copy, and pitch use identical nouns. - Use Case: During a hackathon kickoff, feed the Skill your idea brief, answer its interview questions, and receive a docs/PRD.md that still gives clear orders at hour 20 and feeds a pre-ranked cut list to scope-guard. ## Quick Start Ask the assistant to run the prd-writer skill on your idea brief to produce a hackathon PRD at docs/PRD.md.
