name: figma-extract description: Pull a Figma file's node tree, design tokens, and embedded assets into the project cwd as a structured snapshot. od: scenario: figma-migration mode: extract

Figma extract

Spec §10 / §21.3.1: the figma-migration scenario starts with a Figma file URL + an OAuth token. This atom turns that pair into the authoritative on-disk record subsequent stages (token-map, generate, critique) operate on.

Inputs

Source	Required	Notes
Figma file URL or node-id	yes	Provide via the figma-oauth GenUI surface or od plugin apply --input fileUrl=…
Figma OAuth token	yes	Routed through oauth-prompt with oauth.route='connector' and connectorId='figma'; the daemon never stores the token in SQLite

Output

The atom writes a deterministic, JSON-shaped extract under the project cwd:

project-cwd/
├── figma/
│   ├── tree.json        # canonical node tree (id / type / parent / children / box / fills / text)
│   ├── tokens.json      # color + typography + spacing tokens lifted off the file
│   ├── assets/          # rasterised exports of every leaf node that the file marks for export
│   │   └── <node-id>.<png|svg|webp>
│   └── meta.json        # { fileUrl, version, lastModified, exportedAt, atomDigest }

figma/tree.json is the canonical pivot for every downstream atom. figma/tokens.json is the input to token-map. assets/ is the input to generate's media stage.

Convergence

The atom completes when figma/tree.json exists and is non-empty. The until evaluator reads figma.tree.nodes >= 1; if the figma file is empty or the OAuth token expired, the atom emits a clear error event and the run aborts (the user fixes auth or picks a different file).

Anti-patterns the prompt fragment forbids

• Synthesising a tree from screenshots when the OAuth path failed — always re-prompt the user; never make up node ids.
• Dropping unsupported node types silently; record them in meta.json.unsupportedNodes[] so the human can audit gaps.
• Treating component instances as duplicates; record componentRef links so token-map can de-duplicate at the right boundary.

Status

Implemented by the daemon runner in apps/daemon/src/plugins/atoms/figma-extract.ts. It fetches and walks the Figma REST tree, records unsupported nodes, lifts tokens, and rasterizes supported assets.
