# Design System

> Guided, section-by-section GDD authoring for a single game system. Gathers context from existing docs, walks through each required section collaboratively, cross-references dependencies, and writes incrementally to file.

# Design System

This is a full-fidelity Codex port of a large upstream studio workflow. Its
detailed phases, templates, checks, and handoff prompts live in
[`references/full-workflow.md`](references/full-workflow.md) to keep skill
discovery lightweight.

## Required procedure

1. Read `references/full-workflow.md` completely before executing this skill.
2. Follow its phases in order and preserve all approval, review, testing, and
   evidence gates.
3. Adapt shell syntax to the detected platform; use PowerShell on Windows and
   POSIX syntax on macOS/Linux.
4. Inherit the active Codex model and permission mode. Never weaken sandbox,
   approval, provenance, or human creative-control boundaries.
5. If a referenced project artifact is absent, report the gap and use the
   documented fallback instead of inventing completion evidence.
