## Summary

Drawgent is a new tool that bridges coding agents like Claude Code, Codex, and opencode with Excalidraw whiteboards. It allows developers to request diagrams via a chat panel or by writing "AGENT:" notes directly on the canvas. The agent views the scene, makes live edits, and marks the task as done.

The tool requires users to have their own agent installation and login. Setup involves installing Node.js and configuring an ACP bridge, with specific adapters for Claude and Codex. It uses a headless Chrome instance for rendering and supports connecting to existing excalidraw.com rooms, where human collaborators can interact with the agent in real-time. Traffic in these rooms is end-to-end encrypted.

Drawgent is built with Rust and includes an MCP server for canvas tools. It supports local development and Docker deployment. Limitations include the need for Chrome for rendering and the fact that Claude Code attachment works via forking rather than direct injection. The project is open-source, with code available for building from source.

## Key points

- Drawgent links Claude Code, Codex, or opencode to Excalidraw for live diagram editing.
- Users can trigger agent actions via chat or by writing AGENT: notes on the canvas.
- The tool supports joining excalidraw.com rooms with end-to-end encrypted collaboration.

## Why it matters

It enables visual collaboration between developers and AI coding agents, allowing for real-time diagram creation and modification within existing whiteboard workflows.
