What problem does it solve? Product concepts often fail because teams commit resources before validating the customer problem, feasibility, and risks. This Skill stress-tests a concept using Amazon's Working Backwards PRFAQ method, forcing customer-first clarity before any PRD or build work begins. ## Core Features & Use Cases - Five-stage coaching workflow: Ignition, Press Release, Customer FAQ, Internal FAQ, and Verdict, each with reference files that challenge vague answers and demand specifics. - Research-grounded drafting: Parallel artifact-analyzer and web-researcher subagents scan project documents and current market data to inform competitive and feasibility claims. - Headless mode: Accepts --headless / -H with a structured input schema (customer, problem, stakes, solution) to autonomously produce a first-draft PRFAQ. - Use Case: A founder with a rough product idea runs the PRFAQ challenge, survives devil's-advocate customer and stakeholder questions, and walks away with a complete PRFAQ document plus a token-efficient distillate ready to feed PRD creation. ## Quick Start Ask the assistant to run the PRFAQ challenge on your product concept, providing who the customer is, their problem, why it matters, and your solution idea.
