What problem does it solve? Writing a Game Design Document from scratch is slow and inconsistent — sections get skipped, economies stay vague, and failure states are forgotten. This Skill produces a complete, cross-referenced GDD from a rough concept, flagging gaps honestly instead of inventing details. ## Core Features & Use Cases - 14-Section GDD Template: Covers game overview, core loop, mechanics, economy, progression, assets, factions, milestones, and monetization, with digital-only and physical-only sections applied as needed. - Gap Flagging System: Marks unknowns as [TBD], unproven beliefs as [ASSUMPTION], and balance concerns as [DESIGN RISK] so weak spots are visible. - Detailed Reference Guidance: Includes per-section examples from shipped GDDs (asymmetric card games, Web3 pet games) and a table of common anti-patterns to avoid. - Use Case: Describe a concept like "2-player asymmetric hacker vs defender card game" and receive a saved docs/GDD-<GameName>.md with completed sections, resource conversion chains, and flagged design risks. ## Quick Start Ask the AI to create a GDD for your game concept, for example a Web3 idle pet game on Avalanche with crafting and NFT evolution.
