What problem does it solve? Ambiguous PRDs and requirement descriptions cause AI coding agents to make wrong assumptions. This Skill interrogates the requirement until flows, boundaries, exceptions, and key concepts are unambiguous, then persists a clarification document before any technical design begins. ## Core Features & Use Cases - Ambiguity Detection: Finds vague wording, undefined concepts, missing information, contradictions, and unspecified implementation-relevant points, then asks grouped, answerable questions. - Iterative Clarification: Refines follow-up questions based on user answers until the requirement is fully clear, without making business assumptions on the user's behalf. - Structured Output & Handoff: Writes a Markdown clarification document (background, scope, key flows, boundaries, concept definitions, acceptance criteria, open questions) to .Knowledge/req-docs/ and automatically chains into the f2s-req-tech technical design step. - Use Case: Paste a rough PRD for a review-template feature; the agent asks targeted questions about states, permissions, and edge cases, saves the clarification document, and proceeds to the technical plan. ## Quick Start Ask the agent to clarify this PRD and resolve all ambiguities before producing a technical design.
