Richie 2205862c2f Add workflow tooling: claude2figma skills, Storybook addons, Figma permissions
Install @storybook/addon-designs for embedding Figma frames in stories
and claude2figma skills (preflight, component-rules, style-binding,
reference-interpreter) for enforcing design token compliance when
writing to Figma. Add PostToolUse hook for use_figma QA reminders and
pre-allow Figma MCP + Code Connect tools in settings.json.

# Figma Preflight
Run at the start of every design session. Do NOT start design work until all steps pass.
**Prerequisite:** Load `figma-use` skill before any `use_figma` call.
---
## Step A — Connection + Config (parallel)
Run these two in parallel:
1. **MCP Connection:** Call `mcp__figma__whoami`. Must return user email and plan. Fail → stop, re-authenticate.
2. **CLAUDE.md:** Read CLAUDE.md. Extract Figma file URL (required — stop if missing), font families, session goal. If fonts field is a placeholder, auto-populate after Step C using STRING variables starting with "Family".
---
## Step B — File + Libraries (parallel)
Parse `fileKey` from the Figma URL, then run in parallel:
1. **File Access:** Call `get_metadata` with extracted nodeId and fileKey. Must return file name and pages.
2. **Libraries:** Call `get_libraries` with fileKey. Store subscribed libraries as **Library Registry** (name, libraryKey, description). These enable `search_design_system` to find library styles and components during design work.
---
## Step C — Styles + Variables + Components (single use_figma call)
Combine all three inventories in one script:
```javascript
const textStyles = await figma.getLocalTextStylesAsync();
const paintStyles = await figma.getLocalPaintStylesAsync();
const collections = await figma.variables.getLocalVariableCollectionsAsync();
const variables = await figma.variables.getLocalVariablesAsync();
const grouped = {};
for (const v of variables) {
const key = v.resolvedType;
if (!grouped[key]) grouped[key] = [];
grouped[key].push({ name: v.name, scopes: v.scopes });
}
const components = {};
for (const page of figma.root.children) {
await figma.setCurrentPageAsync(page);
const sets = page.findAll(n => n.type === "COMPONENT_SET");
const solos = page.findAll(n => n.type === "COMPONENT" && n.parent.type !== "COMPONENT_SET");
if (sets.length > 0 || solos.length > 0) {
components[page.name] = {
sets: sets.map(c => c.name),
solos: solos.map(c => c.name).slice(0, 15),
};
}
}
return {
textStyles: textStyles.map(s => s.name),
paintStyles: paintStyles.map(s => s.name),
collections: collections.map(c => c.name),
variableCount: variables.length,
byType: Object.fromEntries(
Object.entries(grouped).map(([type, vars]) => [type, vars.map(v => v.name)])
),
components
};
```
Store **names only** in context. IDs are looked up on-demand during design work. Library styles/variables are discovered via `search_design_system`.
---
## Token Map
After Step C, derive a semantic index from variables grouped by `scopes`:
| Role | Scope | Example names |
|---|---|---|
| Background fill | `FRAME_FILL`, `SHAPE_FILL` | `background/surface`, `color/neutral-100` |
| Text color | `TEXT_FILL` | `text/primary`, `color/neutral-900` |
| Border / stroke | `STROKE_COLOR` | `border/default`, `color/neutral-300` |
| Gap | `GAP` | `gap/sm`, `spacing/xxs` |
| Padding | `PADDING` | `padding/md`, `spacing/section-xl` |
| Border radius | `CORNER_RADIUS` | `radius/sm`, `radius/full` |
