---name: figma-usedescription: **MANDATORY prerequisite** — you MUST invoke this skill BEFORE every `use_figma` tool call. NEVER call `use_figma` directly without loading this skill first. Skipping it causes common, hard-to-debug failures. Trigger whenever the user wants to perform a write action or a unique read action that requires JavaScript execution in the Figma file context — e.g. create/edit/delete nodes, set up variables or tokens, build components and variants, modify auto-layout or fills, bind variables to properties, or inspect file structure programmatically.disable-model-invocation: false---

use_figma — Figma Plugin API Skill

Execute JavaScript in Figma files via the Plugin API. Always pass skillNames: "figma-use" when calling use_figma (logging parameter, doesn't affect execution).

If the task involves building or updating a full page, screen, or multi-section layout in Figma from code, also load figma-generate-design. It provides the workflow for discovering design system components via search_design_system, importing them, and assembling screens incrementally. Both skills work together: this one for the API rules, that one for the screen-building workflow.

If the task involves creating or building a component in Figma (even a single component), also load figma-generate-library. It owns the component-creation workflow — variable foundations first, variant sets, then design token bindings — that figma-use alone doesn't cover. Build the token/variable foundation before the component, then bind the component's fills/cornerRadius/spacing to those variables rather than inlining literals where a token exists.

IMPORTANT: Whenever you work with design systems, start with working-with-design-systems/wwds.md to understand the key concepts, processes, and guidelines for working with design systems in Figma. Then load the more specific references for components, variables, text styles, and effect styles as needed.

$fig — the plan-based builder API (ALL NODE CREATION MUST USE THIS)

$fig is a global that is responsible for all node creation. It auto-flushes at script end (no $fig.done() needed), handles font preloading, batches mutations, and orders property assignment correctly. Use it for all node creation and mutation operations. Never use figma.createFrame(), figma.createText() or any figma.create* methods. They do not exist in this environment.

Copy these patterns

Build an auto-layout frame with children — single call:

$fig.autoLayout(
  // fixed width; omit height to hug vertically
  { name: 'Todo List', layoutMode: 'VERTICAL', width: 480 },
  ['item 1', 'item 2', 'item 3'].map((item) =>
    $fig.autoLayout(
      // Set `layoutSizingHorizontal` to FILL since auto-layout is hug x hug by default
      { name: 'Todo Item', layoutSizingHorizontal: 'FILL' },
      [$fig.text({ characters: item, fontName: { family: 'Inter', style: 'Bold' } })],
    ),
  ),
).screenshot() // Screenshot new node trees to verify. Prefer `.screenshot()` over `get_screenshot` call after `use_figma`.

N parallel items for repeated small UI elements like swatches, list items, etc.:

const ITEMS = [
  { name: 'A', bg: hex('#ffffff'), accent: hex('#0969da') },
  { name: 'B', bg: hex('#fff8f1'), accent: hex('#bf5af2') },
  // ...add more here
]
ITEMS.forEach((v, i) => $fig.autoLayout({ name: v.name, x: i * 410, width: 390, fills: [{ type:'SOLID', color: v.bg }] }, [
  $fig.text({ characters: v.name, fills: [{ type:'SOLID', color: v.accent }] }),
]))

Update existing nodes — by query or by id:

$fig.query('FRAME[name=Header] TEXT[name=Title]').set({ characters: 'New Title', fontSize: 24 })
$fig.get('1:42').set({ opacity: 0.8, cornerRadius: 12 })

Add a node inside an existing node

$fig.get('1:42').append($fig.autoLayout({ name: 'New Frame' }))

Create a component with a few different variants

const SIZES = ['Small', 'Medium', 'Large']
$fig.variants({ name: 'Button' }, SIZES.map((size) => $fig.component({ name: `Size=${size}`, layoutMode: 'HORIZONTAL', /** other props */ })))

⚠️ $fig.variants does not position the variants — they stack at (0,0) and the set renders as one collapsed, overlapping element. You must grid the variants and resize the set afterward. See fig-builder.md for the required follow-up recipe.

Building a component — even a single one? Binding tokenized values is part of finishing the job, not a preference. A component is not complete while any value that has a corresponding design token — one that already exists in the file, or that you created from the source — is still a hardcoded literal. When a token exists for a fills color / cornerRadius / padding / itemSpacing, bind it: build a $fig.varCollection (primitive tier + semantic tier aliased to it) and pass the variable handle straight into the property. Anti-pattern to avoid: do NOT copy resolved token values into local JS constants (e.g. const VARIANTS = [{ bg: '#2c2c2c' }]) and paint with hex(...) — that silently bypasses variables even though the source defines tokens. This applies to a single component as much as a full design system. Only bind values that actually have a token — values with genuinely no token (one-off geometry, icon pixel sizes, static 1px dividers) correctly stay literal; don't invent tokens to bind. If you create the variables in one use_figma call and build the component in a later one, rehydrate the handles first ($fig.getVar(id) or figma.variables.getVariableByIdAsync using the IDs you returned) — a handle from a previous call isn't in scope. Worked recipe: fig-builder.md → Building a component with bound variables.

Create an instance of a component

// First arg can be a node ID ('1:2') OR a library asset key
// from `search_design_system` results (the `componentKey` field).
$fig.instance('1:2', { name: 'Cancel Btn', props: { label: 'Cancel'}})

Consume styles/variables

$fig.autoLayout({ name: 'Card', itemSpacing: spacingVar, fills: fillStyle })

// Looked up by asset key from `search_design_system` (the `key` field)
$fig.autoLayout({ fills: $fig.getStyle(BG_STYLE_KEY) })
$fig.rectangle({ fills: [{ type: 'SOLID', color: $fig.getVar(BRAND_VAR_KEY) }] })

Use design-system assets by key (from search_design_system)

search_design_system returns componentKey for components and component sets, and key for styles and variables. Pass these straight into the unified $fig lookup — the plan queues the library import automatically, so you don't need a separate await figma.importComponentByKeyAsync(...) / importStyleByKeyAsync(...) / importVariableByKeyAsync(...) step.

// One call site, many input shapes — node IDs, real variable/style ids,
// AND 40-char asset keys (e.g. '49c8754d4b898e176148650df612a47998a8c4a1')
const btn        = $fig.get(BUTTON_KEY)                    // component / component set
const instance   = $fig.instance(BUTTON_SET_KEY, {         // create an instance from a set
  props: { Size: 'md', Variant: 'primary' },
})
const heading    = $fig.getStyle(HEADING_TEXT_STYLE_KEY)   // paint / text / effect / grid style
const brand      = $fig.getVar(BRAND_COLOR_VAR_KEY)        // variable

$fig.text({ characters: 'Hello', textStyle: heading })
$fig.rectangle({ fills: [{ type: 'SOLID', color: brand }] })

Discover a set's variant props from its key — search_design_system returns a set's componentKey, not its variant properties. This is two use_figma calls: call 1 returns the set's property definitions and its variants so their props come back to you in the tool result; then, knowing the valid props, call 2 instantiates the variant you want.

const setHandle = $fig.get(BUTTON_SET_KEY)
await $fig.done()
const set = setHandle.node
if (!set || set.type !== 'COMPONENT_SET') {
  throw new Error(`Key ${BUTTON_SET_KEY} is not a COMPONENT_SET`)
}
return {
  componentPropertyDefinitions: set.componentPropertyDefinitions,
  variants: set.children
    .filter((c) => c.type === 'COMPONENT')
    .map((c) => ({ name: c.name, variantProperties: c.variantProperties })),
}

// Call 2 — instantiate with props you picked from call 1's output
$fig.instance(BUTTON_SET_KEY, { props: { Size: 'Large', Kind: 'Secondary' } })

Bulk component swap — $fig.query().set():

const chevron = $fig.get('CHEVRON_KEY')
$fig.query('INSTANCE[name=arrow_drop_down]').set({ mainComponent: chevron })

.query() and .values() for search and projecting child values

const menuArrows = $fig
  .query('PAGE[name=Menu] INSTANCE[mainComponent.name*=arrow], PAGE[name=Menu] INSTANCE[mainComponent.name*=chevron]')
  .values(['id', 'name', 'mainComponent.name', 'mainComponent.id']);

// Use quotes for multi-word selector values
const expandComponents = $fig
  .query('COMPONENT[name*=expand], COMPONENT[name*=chevron_down], COMPONENT[name*=chevron_up], COMPONENT[name*="multi word name"]')
  .values(['id', 'name']);

Perform operations on another page:

// Switch to a specific page (loads its content)
const targetPage = figma.root.children.find((p) => p.name === "My Page");
await figma.setCurrentPageAsync(targetPage);
$fig.query('INSTANCE[name=arrow_drop_down]').set({ ... })

Gradient via helper — no manual transform matrix needed:

$fig.gradient(node, 'LINEAR', [
  { position: 0, color: { r: 0, g: 0, b: 0 } },
  { position: 1, color: { r: 1, g: 1, b: 1 } },
])

Hex helper at script top:

const hex = h => { const n = parseInt(h.replace('#',''), 16); return { r:((n>>16)&255)/255, g:((n>>8)&255)/255, b:(n&255)/255 } }
// then: color: hex('#2563eb')

Chaining on plan nodes — alternative to children array:

const card = $fig.autoLayout({ name: 'Card', layoutMode: 'VERTICAL' })
card.text({ characters: 'Title', fontSize: 20 })
card.text({ characters: 'Description', fontSize: 14 })

$fig create + mutate API (full surface)

• Create: $fig.autoLayout / .frame / .text / .rectangle / .ellipse / .polygon / .star / .line / .vector / .section / .component / .page — all (opts?, children?). Plan nodes are chainable.
• Create from SVG — the preferred ICON path: $fig.svg(svgStr, opts?) builds a vector node tree from an SVG string. Prefer real vector icons: import the icon's SVG source (inline <svg>, the .svg asset, or the source icon-library glyph — e.g. lucide/heroicons) via $fig.svg(...) rather than approximating an icon with a typed emoji/Unicode glyph (★ ⚙ 🔍 ☰ ▾) or a plain rectangle. A simple glyph or shape is a fine fallback when the real SVG genuinely can't be obtained — just reach for the SVG first. (Don't reconstruct an icon from rotated line/rect primitives, though — that renders broken.) Full recipe (viewBox+width/height sizing, currentColor, INSTANCE_SWAP for design-system icons): figma-generate-design → Icons.
• Create an instance of a component: $fig.instance(compRef, opts?) — compRef is a component plan node, a node ID string, OR a library asset key (componentKey from search_design_system); the import is queued in the plan automatically.
• Grouping/boolean: $fig.group / .union / .subtract / .intersect / .exclude / .variants — all (opts?, children?).
• Read: $fig.get(id) wraps an existing SceneNode — id can be a real node ID OR a library asset key (componentKey from search_design_system); the import is queued in the plan automatically. $fig.query(selector, scope?) returns { length, values(paths), first(), last(), each(fn), filter(fn), set(props), moveTo(parent, idx?), remove() }. Selectors are CSS-like (e.g. 'FRAME[name*=Card] TEXT'). $fig.getStyle(nameOrIdOrKey) and $fig.getVar(nameOrIdOrKey) accept the matching key values from search_design_system.
• Mutate: $fig.set(target, props), .delete(...nodes), .move(target, parent, idx?), .clone(target, props?), .append(parent, child), .addAt(parent, idx, child), .replace(old, new), .reorder(parent, children), .gradient(node, type, stops, transform?), .image(node, hash, scaleMode?).
• Plan-node methods (chainable): .set(), .remove(), .clone(), .moveTo(parent, idx?), .append(child), .query(selector), .screenshot({scale?, contentsOnly?}), and the .node getter for the materialized SceneNode (null pre-flush).

When to use the raw Figma Plugin API

Only these cases — and even then, mix raw API with $fig in the same script:

• Mid-script async result needed: await figma.setCurrentPageAsync(...), await figma.loadFontAsync(...) — must complete before subsequent plan steps can use the result. (Importing library components is NOT one of these cases: pass the componentKey straight into $fig.get(...) / $fig.instance(...) and pass variant property values in props. $fig queues the library import in the plan and resolves the variant for you.)
• Mid-script real node state read: measured width / height after auto-layout, computed colors, getStyledTextSegments — materialize mid-script, then read .node on the plan node. See references/fig-builder.md for the mid-script inspection pattern.
• Things $fig genuinely doesn't expose: node.setRangeFontName(...), etc. — access via planNode.node (see references/fig-builder.md).

Critical Rules

1. Only use $fig for creating / bulk-editing nodes ($fig.autoLayout(...), $fig.text(...), $fig.query(...).set(...)). Raw Plugin API is the fallback — use it only when $fig can't express the operation (intermediate node-state reads, non-SceneNode types like Variables). Library components are NOT a reason to leave $fig: $fig.get(componentKey) / $fig.instance(componentSetKey, { props }) queue the library import and resolve the variant for you. See references/fig-builder.md and references/critical-rules-deep.md for worked WRONG/RIGHT examples.

2. Do not use findOne, findAll, findAllWithCriteria, findChildren, findChild directly for node searching They are more verbose, error-prone, and less efficient than query(). Additionally, do not use recursion to search.

3. Avoid return / $fig.done() if only using $fig — runtime auto-flushes and returns a FigDoneResult with created/updated node IDs. Use return if you need raw plugin API mid-script or other data.

4. Build up larger designs incrementally by section. Refer to the figma-generate-design skill for the placeholder + replace workflow. Create screens with placeholders inside, e.g. $fig.autoLayout({ name: 'Header', layoutSizingHorizontal: 'FILL', placeholder: true }), then make subsequent use_figma calls to replace them and screenshot: $fig.get("PLACEHOLDER_ID_FROM_PREVIOUS_STEP").replace( ... ).screenshot(). You can make up to 5 .screenshot() calls per tool call. If you need to make more screenshots, you are doing too much work and need to break down the task into multiple use_figma calls.

5. Plain JS with top-level await. Code is auto-wrapped in async. Do NOT wrap in (async () => {})().

6. Colors are 0–1 RGB; ALL fields required. {r, g, b} — no hex:, no a: in color. Opacity goes outside color: {type:'SOLID', color:{r,g,b}, opacity: 0.5}. Hex helper: const hex = h => { const n = parseInt(h.replace('#',''), 16); return { r:((n>>16)&255)/255, g:((n>>8)&255)/255, b:(n&255)/255 } }. See references/critical-rules-deep.md for WRONG/RIGHT.

7. No curl / wget / Read of Figma URLs from Bash. Figma file access ONLY via use_figma and mcp__figma__* tools. After get_screenshot, the image is inlined in the tool result — do NOT re-fetch or re-Read it.

8. Empty / unsupported responses are terminal. Accept and move on — don't try alternative bypass paths.

9. Verify node-type before touching a property. Only FRAME / COMPONENT / COMPONENT_SET / INSTANCE / GROUP / SECTION / PAGE have .children. GROUP has no fills / strokes / cornerRadius. TEXT has no cornerRadius / padding* / layoutMode. layoutPositioning='ABSOLUTE' needs parent with layoutMode !== 'NONE'. Check '<prop>' in node or grep references/plugin-api-standalone.d.ts. Full list in references/critical-rules-deep.md.

10. Don't re-query the same info. get_metadata / get_comments on the same target twice yields the same result. Cache mentally.

11. Be decisive once you have enough info. Don't keep gathering — the marginal information from a 3rd screenshot or 4th metadata call is near-zero.

12. "An unexpected error occurred" from use_figma is server-side, not your script bug. Don't retry unchanged — change approach (smaller batch, different selector, drop one node-prop).

13. NEVER call mcp__figma__get_design_context. FORBIDDEN. This tool requires a selection (no selection exists in this environment), so every call will fail. The error is not recoverable — calling it just burns a tool slot and forces a retry. For structured reads of the file, use mcp__figma__get_metadata (for top-level frame discovery) and use_figma with $fig.query() instead. Never call get_design_context for any reason.

14. ≤3 codebase Read calls when the task references source code. Beyond that, grep only. The 4th codebase Read is forbidden — write your use_figma script with what you have.

15. 3 retries of the same error → switch approach. Most often: switch to $fig (which handles ordering automatically). Patching the raw API isn't working.

16. Must use auto-layout unless you have a compelling reason not to. Create auto-layout frames with $fig.autoLayout(...) instead of absolutely-positioning nodes. New auto-layout frames are created with both axes hugging content. Explicitly assign layoutSizingHorizontal or layoutSizingVertical to 'FILL' for auto-layout children if you want them to fill the auto-layout container's counter axis.

17. Gradient paints need ALL fields: type, gradientStops, gradientTransform (a [[a,b,tx],[c,d,ty]] matrix). Missing any throws validation error. See references/critical-rules-deep.md.

18. Discover available fonts, esp. for style variations. Use await figma.listAvailableFontsAsync() to discover available fonts for $fig.text({ fontName: ... }).

19. Set variable scopes explicitly when creating variables. The default ALL_SCOPES pollutes every property picker. Use specific scopes — ['FRAME_FILL', 'SHAPE_FILL'] for backgrounds, ['TEXT_FILL'] for text, ['GAP'] for spacing, ['CORNER_RADIUS'] for radii; primitives that shouldn't appear in pickers get []. In $fig, pass scopes to colorVar / numVar; in the raw API, set variable.scopes. See references/variable-patterns.md.

Bulk mutation of existing nodes (swap/update/replace) is COMPLETE in 3 use_figma calls

For tasks like "swap N icons", "update M colors", "replace K instances":

1. DISCOVER + MUTATE in one script (find via figma.currentPage.query(), import any components, mutate via $fig.query(...).each(...), return count).
2. VERIFY (optional) — read-only .query() count.
3. FINAL REPORT in assistant text, no tool call. STOP.

NO 4th call. NO chasing the last 20% of edge cases. If Call 1 errors, fix and redo — that's still your one mutation call. Full template in references/critical-rules-deep.md.

Node property gotchas

Do not guess node properties or assume CSS-like properties. Accessing non-existent properties will throw TypeError: node.foo: no such property 'foo' on TYPE node. Each throw burns a retry. plugin-api-standalone.index.md contains the list of all symbols in the API. Use that file and grep the full API typings in plugin-api-standalone.d.ts for the full definitions.

• Only FRAME / COMPONENT / COMPONENT_SET / INSTANCE / GROUP / SECTION / PAGE have .children. RECTANGLE, TEXT, ELLIPSE, POLYGON, STAR, VECTOR, LINE, SLICE, STICKY, SHAPE_WITH_TEXT, STAMP, CONNECTOR, TABLE, WIDGET, EMBED, MEDIA do NOT. Check 'children' in node before accessing a node's children.
• GROUP has NO fills / strokes / cornerRadius. Apply paints/radii on the child shapes inside.
• Figma auto-layout != CSS flexbox. There is no such thing as margin.
• TEXT DOES NOT HAVE container properties. Text has font / size / decoration / fills. Do not use container properties like padding, layout mode, item spacing, etc.
• INSTANCE descendants are read-only for structural ops — you cannot appendChild / insertChild into an instance child. Edit the source COMPONENT or detach first.
• **Never use primaryAxisSizingMode or counterAxisSizingMode on a node. ** Use layoutSizingHorizontal or layoutSizingVertical with 'FIXED' | 'HUG' | 'FILL'. Use 'FILL' only when the parent has auto-layout.
• There is NO instance.swapMainComponent(...). Use instance.setProperties({...}) with the component-property variant value, OR $fig.query(...).set({props: {...}}). There IS instance.swapComponent(component) (different method name).
