Design System — Design System Architecture

Activate When

• User invokes /godmode:designsystem
• User says "design system," "design tokens," "theme architecture," "Figma to code"
• Creating a shared component library or establishing token architecture
• Building theme support (light/dark, multi-brand) or Figma-to-code pipeline
• Versioning/distributing a design system package or auditing for consistency

Workflow

Step 1: Assess Current State

DESIGN SYSTEM ASSESSMENT:
Project: <name>  Framework: <React/Vue/Angular/Svelte/Web Components>
Existing system: <none/partial/mature>
Token coverage: Colors/Spacing/Typography/Shadows/Borders/Motion — <defined/partial/none> each
Theme support: <none/light-dark/multi-brand>
Component count: <N>  Storybook: <yes/no>  Figma integration: <yes/no>
Maturity: NONE | STARTER | GROWING | MATURE

Step 2: Token Architecture

Three-tier architecture is mandatory:

TIER 1: PRIMITIVES (raw values)      --primitive-blue-500: #3b82f6;
TIER 2: SEMANTIC (meaning)           --color-primary: var(--primitive-blue-500);
TIER 3: COMPONENT (specific)         --button-bg: var(--color-primary);

Colors: Neutral scale (50-950), brand scale, feedback (red/green/amber). Semantic: bg, surface, text-primary/secondary/tertiary, primary/hover/active, error/success/warning, border/border-strong/border-focus.

Spacing: 4px base unit scale: 0, px, 0.5, 1, 1.5, 2, 3, 4, 5, 6, 8, 10, 12, 16, 20, 24 (in rem).

Typography: Font families (sans, mono), sizes (xs-5xl modular 1.25 scale), weights (400-700), line heights (tight/normal/relaxed).

Shadows: xs through 2xl + inner + focus ring.

Step 3: Component API Standards

STANDARDS:
- variant: "primary"|"secondary"|"ghost"|"danger"  size: "sm"|"md"|"lg"
- Extend native HTML element props. Export all prop types.
- forwardRef on every component wrapping native elements. Set displayName.
- Compound components: <Card><Card.Header/><Card.Body/></Card>
- Defaults: variant="primary", size="md"
- on<Event> convention. Support controlled and uncontrolled modes.
- className always accepted as escape hatch.

Step 4: Theme System

Light/dark via CSS custom properties on [data-theme]. ThemeProvider with system preference detection, localStorage persistence, flash-free SSR. Multi-brand via [data-brand] overriding primitive tokens.

Step 5: Design-to-Code Pipeline

Figma Variables/Tokens Studio -> tokens.json (W3C format) -> Style Dictionary -> outputs (CSS variables, TypeScript constants, Tailwind config). CI automation: Figma webhook -> generate -> PR -> visual regression test.

Step 6: Versioning & Distribution

Semantic versioning: MAJOR (remove token/component, rename, change defaults), MINOR (add component/token/variant), PATCH (fix values/bugs). Package structure: dist/css/, dist/js/, dist/tokens/. Release: version bump -> build -> changelog -> publish -> deploy Storybook.

Step 7: Storybook Documentation

Initialize with essential addons (a11y, viewport, docs, designs). Structure: Introduction > Foundations (Colors, Typography, Spacing, Shadows) > Components (Atoms, Molecules, Organisms) > Patterns > Theming.

Step 8: Audit Report

DESIGN SYSTEM AUDIT:
  Token Coverage: Colors/Spacing/Typography/Shadows — <N>/<N> used, <N> hardcoded
  Component API Compliance: <N>/<N> standards-compliant
  Theme System: Light/Dark/System preference/Persistence/Flash-free
  Pipeline: Figma sync automated/manual/none
  Documentation: Storybook coverage <X>%
  Score: <N>/100  Maturity: NONE | STARTER | GROWING | MATURE

Step 9: Remediation Plan

Priority 1 (Critical): blocks adoption. Priority 2 (High): degrades consistency. Priority 3 (Medium): improves DX. Priority 4 (Low): polish.

Step 10: Commit

Commit per area: "designsystem: <tokens|theme|pipeline|storybook> — <description>"
Transition: Run /godmode:ui for component audit, /godmode:a11y for accessibility

Key Behaviors

1. Tokens are the single source of truth. Every visual decision is a token.
2. Three-tier architecture is mandatory. Primitives -> Semantic -> Component.
3. Keep component APIs predictable. Same prop naming, composition, typing everywhere.
4. Theming is infrastructure. Dark mode requires complete semantic token layer.
5. Automate the pipeline. Manual sync guarantees drift.
6. Version like a product. Semver, changelogs, migration guides.
7. Storybook is the documentation. If not in Storybook, it does not exist.

Flags & Options

Flag	Description
--audit	Audit existing design system maturity
--tokens	Token architecture only
--theme	Theme system setup
--pipeline	Figma-to-code pipeline setup
--storybook	Storybook documentation setup
--init	Initialize complete design system from scratch

# Build and test design system
npx storybook build --ci
npx chromatic --exit-zero-on-changes
npx style-dictionary build

IF token coverage < 90%: audit for hardcoded values. WHEN Storybook build fails: fix imports, check addon compatibility. IF visual regression detected: review diff, update baseline if intentional.

HARD RULES

• NEVER use raw hex/rgb in component code — always reference semantic tokens
• NEVER skip the semantic token layer
• NEVER create a component without a Storybook story
• NEVER publish without a CHANGELOG entry
• NEVER modify token values affecting layout without MAJOR version bump
• ALL components MUST forward refs and accept className

Auto-Detection

1. Scan for tailwind.config, CSS :root/[data-theme], tokens.json, style-dictionary config, .storybook/
2. Detect component library: shadcn/ui, radix, chakra, mantine, MUI
3. Check for Figma integration: .figma*, figma-tokens.json
4. Determine maturity: NONE (>10 hardcoded) | STARTER (<50% coverage) | GROWING | MATURE

Multi-Agent Dispatch

Agent 1 (tokens): Build/audit token architecture — primitives, semantics, themes
Agent 2 (components): Audit component API compliance — ref forwarding, prop naming
Agent 3 (pipeline): Configure Figma-to-code pipeline — Style Dictionary, CI
Agent 4 (docs): Set up Storybook — foundation stories, component stories
MERGE: All -> visual regression test -> unified report

TSV Logging

Log to .godmode/designsystem-results.tsv: timestamp\tskill\ttarget\taction\ttokens_count\tcomponents_count\tcoverage_pct\tstatus

Success Criteria

1. All tokens in single source (Style Dictionary/Figma Tokens)
2. Semantic layer between primitives and components
3. Every component references only semantic tokens
4. Light + dark themes work by swapping tokens only
5. Every component has Storybook story with all variants
6. Token pipeline generates CSS custom properties
7. Token coverage >= 90%

<!-- tier-3 -->

Error Recovery

• Tokens out of sync with Figma: Re-export, rebuild, diff, update only if changed.
• Theme switching breaks: Check semantic token usage, verify data-theme attribute, inspect computed styles.
• Storybook fails: Check imports, addon compatibility, clear cache.
• Visual regression false positives: Font rendering diffs, update baselines, use threshold tolerance.

Platform Fallback

Run sequentially if Agent() or EnterWorktree unavailable. Branch per task: git checkout -b godmode-designsystem-{task}. See adapters/shared/sequential-dispatch.md.

Output Format

Print: DesignSystem: {tokens} tokens, {components} components. Theme: {light_dark|single}. Storybook: {passing|failing}. Status: {DONE|PARTIAL}.

Keep/Discard Discipline

After EACH design system change:
  KEEP if: all components use semantic tokens AND Storybook builds AND visual regression passes
  DISCARD if: primitive token used directly OR Storybook breaks OR visual regression detected
  On discard: revert. Fix token mapping before retrying.

Stop Conditions

Loop until target or budget. Never ask to continue — loop autonomously.
Measure before/after. Guard: test_cmd && lint_cmd.
On failure: git reset --hard HEAD~1.

STOP when ALL of:
  - All components reference semantic tokens only
  - Storybook builds and deploys successfully
  - Theme switching works (light/dark) without layout breaks
  - Visual regression baseline established
