What problem does it solve? Writing a game design document from a blank template is intimidating, and self-written GDDs often contain orphan features, internal contradictions, and unscoped ambition. This Skill turns GDD creation into a guided, Socratic workflow that asks the right questions, enforces design pillar alignment, and assigns scope tiers to every feature. ## Core Features & Use Cases - 10-Section Guided Process: Walks through elevator pitch and pillars, core loops, mechanics with MDA tagging, progression, economy, narrative, art, audio, and technical architecture in dependency order. - Pillar Validation & Contradiction Detection: Every feature must justify itself against established design pillars, and cross-section contradictions are flagged immediately. - Scope Tier Marking: Every mechanic and system receives a T1 (Must-Ship), T2 (Launch Target), or T3 (Post-Launch) tier to prevent scope creep. - Use Case: A solo developer with a validated game concept says "help me write my GDD" and is guided through each section with targeted questions, good/bad entry examples, and honest scope feedback. ## Quick Start Ask the assistant to help you write a game design document for your game concept, starting with your elevator pitch and three design pillars.
