What problem does it solve? Turning a raw game idea into a playable prototype often fails due to uncontrolled scope, unclear design goals, and missing quality checks. This Skill structures the journey from a one-sentence idea to a tested, playable build with explicit gates. ## Core Features & Use Cases - Scoped Prototype Design: Clarifies player fantasy, core verb, success/fail conditions, session length, and non-goals before any code is written. - Gated Implementation Workflow: Runs toolchain diagnosis, recommends an engine, and builds in thin vertical slices with a playable build after each slice. - Seven Production Gates: Enforces rights/licensing, format validation, visual consistency, runtime performance, playability tests, regression evidence, and human approval before production promotion. - Use Case: A designer with a one-sentence platformer idea and a two-week deadline uses this Skill to get a scoped prototype plan, an approved engine route, and a playable build with controls sheet and test evidence. ## Quick Start Use the prompt-to-game skill to turn my game idea into a scoped playable prototype with approval gates and test evidence.
