What its author says it does

Copied from the file, not written here

Discover and import design tokens from SUBSCRIBED Figma team libraries into the current file. Use when the user wants to reuse tokens that live in a shared library: triggers 'list library variables', 'what tokens are in our shared library', 'import a variable from our design system library', 'pull in the brand color token from the library'. Works on ANY plan via the Plugin API teamLibrary methods. For LOCAL variables use export-tokens-figma / manage-variables-figma.

library-variables-figma — discover & import team-library variables

Browse the variables published by libraries the current file subscribes to, then import the ones you need. Imported variables get a local id that behaves like any local variable (bind it, read it, reference it).

Skill boundaries

  • use_figma rules — load the official figma-use skill first; it is the full Figma Plugin API reference. Essentials these scripts rely on: plain JS with top-level await + return (no IIFE, no figma.closePlugin(); console.log is not returned), inputs inlined as const at the top of each script, colors in 0–1 range, load fonts before any text op, await figma.getNodeByIdAsync(...), and atomic errors (a failed script applies nothing — read the error, fix, retry).
  • Local (non-library) variables → export-tokens-figma, manage-variables-figma.

Workflow

  1. Discover. Run scripts/list-library-variables.js via use_figma (skillNames: "library-variables-figma"). Optionally set the LIBRARY_NAME / COLLECTION_NAME / TYPE filters. It returns each subscribed collection and the key of every variable in it.
  2. Import. Put the variable key(s) into scripts/import-library-variable.js and run it. It returns the new localId for each. Re-importing is idempotent (same local id).
  3. Use. Bind the imported variable to node properties or reference it from local semantic tokens (see figma-use / manage-variables-figma for binding).

Notes

  • Only subscribed libraries appear. If a collection is missing, enable the library in the file's library settings first (a manual Figma step).
  • getVariablesInLibraryCollectionAsync takes the collection key, not its id.
  • Library variables are read-only references to the source — edit values in the library file, not here.
