Claude Code + Figma: A Deterministic Design Handoff Pipeline

Screenshot prompting has a ceiling. You paste the design, the model makes a plausible approximation, you correct it, and on the next turn it drifts again. Nothing is anchored. The model has no source of truth to check itself against between turns. A context bundle changes the contract. Instead of a pixel reference the model has to interpret every time, you get a structured, referenceable set of files — design tokens, layout IR, component inventory, UI strings — that stay in the session and stay consistent. Claude Code can read them, implement from them, and check its own output against them on demand. This post walks the full pipeline, from bundle export to a reviewed, token-verified implementation, using figmascope , a browser tool that turns any Figma file into exactly that bundle. What makes this deterministic Three things make the bundle referenceable rather than interpretable: Tokens are typed and keyed. tokens.json maps semantic names ( spacing.16 , color.7f5cfe ) to exact values. The model can check its output against the file without re-processing the design. The IR is a tree, not pixels. screens/home.json describes the layout in terms of stack/overlay/absolute/leaf nodes — the same abstraction the implementation target (Compose, React, etc.) uses. There's no visual interpretation step. The bundle is stable across turns. Once it's in the repo, every prompt in the session can reference the same files. Token drift is detectable: ask the model to compare its output against tokens.json and it can do it mechanically. Step 1: Generate the bundle Open figmascope.dev in your browser. Paste your Figma file URL. The exporter runs client-side using the Figma REST API — your Figma personal access token is stored in localStorage and never sent to figmascope's servers. Click Export Agent Context . The page exports top-level frames, resolves design tokens, builds the IR, and downloads context-bundle.zip .
