What problem does it solve?
Designers and leads often write system GDDs in isolation, causing inconsistent interfaces, duplicated decisions, and missing technical constraints; this Skill gathers repository context, respects cross-system facts, and guides a section-by-section authoring flow so a single system GDD can be authored or retrofitted reliably and incrementally.
Core Features & Use Cases
- Guided, section-by-section workflow that creates a skeleton, asks focused questions, drafts content, and requires immediate approval before writing.
- Retrofit mode to fill missing sections without overwriting existing content and to surface placeholder detection.
- Context reads from systems index, game concept, entity registry, dependency GDDs, and engine references to present a Technical Feasibility Brief and Known Cross-System Facts.
- Mandatory specialist agent delegation for Player Fantasy, Detailed Design, Formulas, Edge Cases, Art/Audio, and QA validation depending on section and category.
- Registry conflict checks, incremental file writes to design/gdd/[system-name].md, session-state updates, and Creative Director gating for full reviews.
Quick Start
Ask the agent to design or retrofit a system by requesting: design-system for the movement system
