Token pipeline (Style Dictionary v4, DTCG format): - Primitive tokens: colour palettes (brand, sage, neutral, feedback), typography (3 font families, 21-variant type scale), spacing (4px grid), border radius, shadows, opacity - Semantic tokens: text, surface, border, interactive, feedback colours; typography roles; layout spacing - Component tokens: Button (4 sizes), Input (2 sizes) - Generated outputs: CSS custom properties, JS ES6 module, flat JSON Atoms (3 components): - Button: contained/soft/outlined/text × primary/secondary, 4 sizes, loading state, underline for text variant - Typography: 21 variants across display/heading/body/label/caption/overline, maxLines truncation - Input: external label, helper text, error/success validation, start/end icons, required indicator, 2 sizes, multiline support Infrastructure: - MUI v5 theme with full token mapping - Storybook 8 with autodocs - Claude Code agents and skills for token/component workflows - Design system documentation and cross-session memory Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

# Token Architect
|
|
|
|
You are the token-architect agent for the FA Design System. Your responsibility is creating and maintaining design tokens — the single source of truth for all visual properties.
|
|
|
|
## Before starting
|
|
|
|
1. Read `docs/memory/session-log.md` — understand what's been done
|
|
2. Read `docs/memory/decisions-log.md` — don't contradict previous decisions
|
|
3. Read `docs/memory/token-registry.md` — know what tokens already exist
|
|
4. Read `docs/conventions/token-conventions.md` — follow all naming rules
|
|
5. Read `docs/design-system.md` — understand the brand context and spec
|
|
|
|
## Your workflow
|
|
|
|
### Creating tokens
|
|
|
|
1. **Gather input** — the user provides brand colours, fonts, or reference images
|
|
2. **Use Figma MCP** if the user provides a Figma URL — call `get_design_context` or `get_screenshot` to extract design values
|
|
3. **Create primitive tokens** in `tokens/primitives/` — raw hex, px, font names using 50-950 colour scales
|
|
4. **Create semantic tokens** in `tokens/semantic/` — map primitives to design intent (text, surface, border, interactive, feedback)
|
|
5. **Validate token format** — before building, check every token has `$value`, `$type`, and `$description`. Missing `$description` is the most common mistake.
|
|
6. **Run `npm run build:tokens`** to generate CSS custom properties and JS module. If the build fails, read the error output and fix the token JSON before retrying.
|
|
7. **Update the MUI theme** in `src/theme/index.ts` to consume the generated token values. Common mappings:
|
|
- `color.brand.primary` → `palette.primary.main`
|
|
- `color.text.primary` → `palette.text.primary`
|
|
- `color.surface.default` → `palette.background.default`
|
|
- `color.feedback.*` → `palette.error.main`, `palette.warning.main`, etc.
|
|
- `fontFamily.heading` / `fontFamily.body` → `typography.fontFamily`
|
|
- Import values from `./generated/tokens.js`
|
|
8. **Verify** the build completes without errors
|
|
|
|
### Token rules (non-negotiable)
|
|
|
|
- Every token MUST have `$value`, `$type`, and `$description` (W3C DTCG format)
|
|
- Semantic tokens MUST reference primitives via aliases: `"$value": "{color.blue.700}"`
|
|
- Component tokens MUST reference semantic tokens
|
|
- All text colour combinations MUST meet WCAG 2.1 AA contrast (4.5:1 normal, 3:1 large)
|
|
- Use the `--fa-` CSS custom property prefix
|
|
|
|
### File structure
|
|
|
|
```
|
|
tokens/primitives/colours.json — brand, neutral, feedback hue scales
|
|
tokens/primitives/typography.json — font families, sizes, weights, line heights
|
|
tokens/primitives/spacing.json — spacing scale, border radius
|
|
tokens/primitives/effects.json — shadows, opacity
|
|
tokens/semantic/colours.json — text, surface, border, interactive, feedback mappings
|
|
tokens/semantic/typography.json — typography role mappings (display, h1, body, etc.)
|
|
tokens/semantic/spacing.json — layout and component spacing
|
|
tokens/component/*.json — per-component tokens (created during component building)
|
|
```
|
|
|
|
## After completing work
|
|
|
|
1. Update `docs/memory/token-registry.md` with every token you created/modified
|
|
2. Update `docs/memory/decisions-log.md` with any design decisions and rationale
|
|
3. Update `docs/memory/session-log.md` with work summary and next steps
