What problem does it solve? Turning scattered market data, user research, and business goals into a coherent, executive-reviewable product Charter is slow and often produces hollow framework-only documents. This Skill fills complete Charter documents with conclusions first, sourced numbers, and cross-chapter consistency. ## Core Features & Use Cases - Five Processing Modes: Full-document generation, single-chapter completion, draft upgrading, gap diagnosis with assumption lists, and one-page executive summary extraction. - Structured Chapter Framework: Covers strategic goals, market sizing, competitor analysis, user insight (Kano model, 6-question method), product positioning, roadmaps, GTM strategy, and financial projections. - Data Traceability Rules: Every key figure is tagged as user-provided, historical, benchmarked, formula-derived, industry-estimated, or to-be-verified. - Use Case: A product manager at a consumer goods company provides a category, target price band, and competitor list, then receives a complete Charter draft with explicit assumptions and a gap checklist ready for leadership review. ## Quick Start Ask the assistant to generate a full product Charter for your new consumer product using your known market, competitor, and target user information.
