Figma preflight

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:

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

Ready to design.

If any step fails, output ❌ with error and stop.
