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 downstream design documents inherit the confusion. This Skill coaches you through producing, refining, or pressure-testing a game brief that a Game Design Document can build on. ## Core Features & Use Cases - Three intent modes: Create a new brief from conversation, 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). - Discovery coaching: Surfaces vision, target players, core loop, scope, references, and content direction through dialogue, with web-research subagents grounding genre and market context. - Persistent workspace: Writes brief.md, addendum.md, and .decision-log.md to a run folder so work can pause and resume across sessions, with polish passes and reviewer gates at finalize. - Use Case: You have a pitch for a roguelike deckbuilder due tomorrow. Activate the skill, choose the fast path, answer one consolidated batch of questions, and receive a polished brief with tagged assumptions ready for review. ## Quick Start Ask the AI to help you create a game brief for your game idea and answer its discovery questions.
