What problem does it solve? Unstructured ideation with AI specs too early, forgets prior decisions, and never defines a finish line. This Skill runs a disciplined explore → pressure-test → converge funnel that ends in one living CONCEPT_BRIEF.md holding a locked concept, honest verdict, and phased roadmap. ## Core Features & Use Cases - Structured ideation funnel: Frame, diverge with 5-7 comparable options, pressure-test with a red-team battery, then lock decisions one at a time into a persistent brief edited in place. - Two modes: Greenfield for blank-slate ideas and refinement for evaluating or rebuilding an existing repo, with a parity contract and pre-mortem to prevent drift. - Honest-advisor stance: Forces a success metric and kill criterion before any roadmap, gives independent verdicts before asking for the user's view, and hands off cleanly to the prompt-pack skill for building. - Use Case: A founder says "I have an idea for a shared-inbox tool — is it worth building?" The Skill pressure-tests viability, locks a beachhead persona and scope, and produces docs/CONCEPT_BRIEF.md ready for build-prompt generation. ## Quick Start Ask the AI to pressure-test your idea and turn it into a locked concept brief with a success metric, kill criterion, and phased roadmap.
