SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) and assets (resource) components.

What problem does it solve?

Forge a complete Game Design Document from a vague idea by guiding an adaptive, pillar-by-pillar interview that yields a vault-grounded design contract (GDD.md) plus a rendered PDF and a decisions registry.

Core Features & Use Cases

  • Adaptive Socratic interview across pillars (Pitch, Loop Economy, Gameplay, Visual/UI Identity, Environment, Audio Identity, Vertical Slice) with an adversarial audit to stress-test decisions.
  • Vault-grounded: every design choice is anchored to MOCs and vault notes, producing a coherent GDD that includes moodboards, beat sheets, and the production plan.
  • Output bundle includes GDD.md, GDD.pdf, decisions.yaml, and a .gdd-scratch.md for resumable sessions; supports retrofit/resume/confront-only modes.

Quick Start

Start a new project: say "let's design a game" and let forge-gdd guide the interview to lock a complete GDD in Vault/40-Projects/<slug>.

FAQPage Schema
How do I create a Game Design Document from a vague game idea?

To create a Game Design Document from a vague idea, you can use an adaptive Socratic interview process that guides you pillar-by-pillar through Pitch, Gameplay, and Visual Identity to forge a complete GDD.

What is the best way to structure a GDD using a knowledge vault?

The best way to structure a vault-grounded GDD is to anchor your design choices to existing MOCs and vault notes, ensuring design coherence across moodboards, beat sheets, and the final production plan.

How do I stress-test game design decisions before production?

You can stress-test game design decisions before production by running an adversarial audit during the interview process, which confronts and validates each pillar choice against your vault knowledge graph.

Can I resume a game design document interview if I stop halfway?

Yes, you can resume a game design document interview because the process saves a .gdd-scratch.md file for resumable sessions, supporting both resume and retrofit routing modes to continue your work.

What files do I need to generate a complete GDD bundle?

To generate a complete GDD bundle, the process outputs a GDD.md file, a rendered GDD.pdf, a decisions.yaml registry, and a .gdd-scratch.md file directly into your Vault/40-Projects directory.

Does the GDD interview process cover game audio and vertical slice planning?

Yes, the GDD interview process covers game audio and vertical slice planning by systematically interviewing across Audio Identity and Vertical Slice pillars alongside core gameplay and economy loops.
