# design-os-figma-plugin

> Free Figma plugin + CLI so Claude Code, Codex or any shell agent can read and edit the Figma file you have open. Local WebSocket, one undo step per mutation, no seat.

A lightweight bridge allowing AI coding agents to inspect, manipulate, and generate Figma canvas nodes in real-time through the official Public Plugin API on Figma Free, without cloud tokens or paid seats.

## Key Capabilities

- **Figma Free Compatible**: Uses the Public Plugin API in Figma Desktop. No paid seat, no access token.
- **Local WebSocket Broker**: Runs locally on ports 9410–9419 with strict origin isolation.
- **Atomic Undo**: Each mutation seals its own undo step so ⌘Z rolls back one atomic operation, not a whole session.
