SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

It prevents slow, inconsistent game design documentation by guiding you through writing a complete GDD for one system using existing project context and dependency awareness.

Core Features & Use Cases

  • Guided, section-by-section GDD writing: prompts you to author Overview, Player Fantasy, Rules, Formulas, Edge Cases, Dependencies, Tuning Knobs, and Acceptance Criteria in sequence.
  • Context-aware and dependency-safe: reads the game concept, systems index, entity registry, and relevant GDDs to ensure your design respects established cross-system facts.
  • Incremental retrofit support: detects which sections are missing or placeholder-only in an existing GDD file and fills only the gaps without overwriting complete content.

Quick Start

Use /design-system movement to generate an informed, incremental GDD for the movement system.

FAQPage Schema
How do I write a game design document without contradicting existing systems?▼

Guide section-by-section GDD authoring while reading the game concept, systems index, entity registry, and relevant GDDs to ensure your design respects established cross-system facts and prevents inconsistencies.

Can I fill in missing sections of an incomplete GDD without overwriting existing content?▼

Yes, you can retrofit incomplete GDD files by detecting which sections are missing or contain only placeholders, then filling only those gaps incrementally without overwriting your complete content.

What sections should a complete system GDD include?▼

A complete system GDD should include Overview, Player Fantasy, Rules, Formulas, Edge Cases, Dependencies, Tuning Knobs, and Acceptance Criteria, authored in sequence with explicit approval gates for each section.

How do I map dependencies before writing a system design document?▼

Map dependencies by performing multi-source reads across the systems index and relevant GDDs, executing feasibility pre-checks and argument resolution to establish cross-system facts before creating the GDD skeleton.

Does context-aware GDD writing support incremental edits and approval gates?▼

Context-aware GDD writing supports controlled incremental edits and explicit approval gates for each section, performing feasibility pre-checks and argument resolution before moving to the next documented system component.
