What problem does it solve? Teams that start coding a new product without a shared definition end up with duplicated business logic, inconsistent terminology, unplanned database migrations, and security models bolted on after launch. This Skill runs a structured founding session that captures every critical decision in one PRODUCT_BRIEF.md document before a single line of code is written. ## Core Features & Use Cases - Nine-step guided interview: Walks through Amazon PRFAQ, Jobs To Be Done, Shape Up appetite and rabbit holes, business model and quotas, technical architecture, database schema, design tokens and terminology, distribution, and MVP scope. - Single source of truth output: Generates a complete PRODUCT_BRIEF.md covering pricing tables, secrets mapping, CORS policy, OWASP checklist, RLS policies, lifetime counters, approved terminology, and launch metrics. - Pre-code checklist: Enforces ten verification gates (constants file, secrets mapping, RLS, analytics events, pre-launch list) before development begins. - Use Case: A founder says "I want to build a new SaaS app." The Skill runs a 45-90 minute structured session, captures all 45 decisions, and outputs a PRODUCT_BRIEF.md that every future coding agent reads first. ## Quick Start Ask the assistant to run the new-product-brief founding session for your product idea and answer the nine stages of questions to generate your PRODUCT_BRIEF.md.
