Steer Design

Generate or refine docs/steering/DESIGN.md — the design guidelines document. This document is the canonical reference for design decisions, the system in use, tokens, patterns, and accessibility requirements that every designer and implementer must follow.

The shared steering-doc flow (exists-check → research → interview → draft → review → write → wiki sync → continue) lives in ../references/steering-doc-process.md. Follow that process with the skill-specific inputs below.

• Doc path: docs/steering/DESIGN.md
• Template: references/design-template.md
• Display name / wiki page: WTF-Design.md
• Commit message: docs: add design guidelines steering document

Step 2 — Research checklist

Use the Agent tool to extract design facts. Do not ask the user for things you can read:

• Design system: Storybook config, component library imports, design-system packages in package.json
• Tokens: CSS custom properties (--color-, --spacing-), Tailwind config, theme files, token definition files
• Components: existing UI components (check components/, ui/, src/components/)
• Figma links: any Figma URLs in README, existing issues, or docs/
• Accessibility: existing WCAG references, axe configs, jest-axe usage
• Responsive breakpoints: Tailwind config, CSS media queries, layout files
• docs/steering/VISION.md if it exists — extract any design principles already stated there

Produce a draft of Stack, Tokens, and Component Patterns from research alone where possible.

Step 3 — Gap-topic list

Ask only about items research could not determine. For each unanswered item, call AskUserQuestion (per ../references/questioning-style.md):

1. Design principles — question: "What 3–5 principles guide every design decision for this product?" / header: "Design principles" / options: pre-fill from VISION.md or any existing design docs.
2. Design system — question: "What design system are you using? Do you have a Figma library?" / header: "Design system" / options: pre-fill with anything found in the codebase or imports.
3. Token gaps — question: "Are there tokens not yet defined in code that designers rely on?" / header: "Token gaps" / options: pre-fill with gaps inferred from design-system research.
4. Responsive strategy — question: "How does the layout adapt across breakpoints?" / header: "Responsive strategy" / options: pre-fill with breakpoints found in the codebase.
5. Accessibility target — question: "Are there accessibility requirements beyond WCAG 2.1 AA?" / header: "Accessibility target" / options: pre-fill with any existing a11y config found.

Step 4 — Writing rules

• Apply strict STE per ../references/ste-writing.md before you write any durable body (shared process Step 4 also requires this).
• Tokens must reflect what is actually defined in the codebase. Do not use aspirational values.
• Component patterns reference real component paths where they exist.
• Accessibility section always includes the baseline rules from the project's CLAUDE.md (if present) plus any additions.
• Principles are written as design directives. They are not engineering constraints.
