gabrielmoreira 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
componentReflinks sotoken-mapcan 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.
