What problem does it solve? Product teams often jump to solutions before validating the customer problem, wasting effort on features nobody needs. This Skill structures early-stage product discovery so decisions rest on classified evidence rather than assumptions. ## Core Features & Use Cases - Customer and Job Framing: Captures ICP, jobs-to-be-done, triggering events, workarounds, and cost of inaction before any solution discussion. - Evidence Ledger: Classifies every claim as observed behavior, user report, sourced fact, inference, assumption, or unknown, with confidence and contradicting evidence. - MVP and Validation Design: Defines the smallest testable promise, non-goals, falsifiable hypotheses, success thresholds, and kill criteria for each experiment. - Use Case: A founder believes small businesses need automated invoicing. Use this Skill to interview the evidence, rank risky assumptions, compare alternatives including doing nothing, and produce a discovery brief with a proposed validation experiment. ## Quick Start Ask the assistant to run product discovery on your product idea and produce a discovery brief covering the customer, evidence, assumptions, MVP scope, and validation experiments.
