What problem does it solve? Turning a raw game idea into a clear, right-sized game brief is hard: assumptions go unexamined, scope balloons, and the resulting document fails as a foundation for the Game Design Document. This Skill coaches you through producing, refining, or pressure-testing a game brief that downstream design work can build on. ## Core Features & Use Cases - Three intent modes: Create a new brief through guided discovery, Update an existing brief against a change signal with a mandatory decision log, or Validate a brief against a quality bar (single-sentence core fantasy, 2-4 pillars, clear core loop, minimal MVP). - Conversational discovery with research grounding: Brain-dump friendly elicitation with web-research subagents for genre landscape, comparable titles, and market context, plus Fast path and Coaching path working modes. - Persistent workspace and audit trail: Writes brief.md, addendum.md, and .decision-log.md to a run folder, supports resume across sessions, headless JSON operation, and external handoffs (e.g., Confluence) at finalize. - Use Case: You have a pitch meeting tomorrow. Invoke the skill, choose the Fast path, answer one consolidated batch of questions, and receive a polished brief.md with [ASSUMPTION] tags to review before the meeting. ## Quick Start Ask the assistant to help you create a game brief for your game idea and answer its discovery questions.
