What problem does it solve? Turning a feature idea into structured requirements that align a team is slow and error-prone; this Skill guides discovery and produces complete PRDs, feature specs, and user stories, or audits existing specs for gaps and anti-patterns. ## Core Features & Use Cases - Spec Writing Modes: Generate PRDs, feature specs, or user stories with acceptance criteria through a four-round discovery process covering problem, scope, success metrics, and behavioral detail. - Spec Audit Mode: Review an existing document against anti-pattern checklists (vague goals, happy-path-only specs, epics disguised as stories) and receive severity-rated findings with rewrite suggestions. - Story Decomposition: Break specs into INVEST-compliant user stories using splitting patterns by workflow step, CRUD operation, persona, or rollout phase. - Use Case: A founder says "spec out our self-serve billing feature" and receives a full feature spec with user flows, system states, edge cases, and testable acceptance criteria. ## Quick Start Ask the assistant to write a PRD for your next feature idea and answer its discovery questions to get a complete markdown spec document.
