GoKawiilNew tool 'drawgent' links Claude Code, Codex and opencode to Excalidraw canvas
Drawgent is a new open-source utility that connects existing installations of Claude Code, Codex or opencode agents to a live Excalidraw whiteboard. Users can request diagrams via a chat panel or annotate a drawing with an 'AGENT:' note, and the connected agent reads the canvas, makes edits, verifies the result, and marks the task done. Setup runs a one-time check per agent, installs ACP adapters and, if needed, a headless Chrome renderer, storing configuration locally.
GoKawiil's interpretation of the reporting above, not reported fact.
By using a developer's own agent CLI, login and repo rather than a hosted service, drawgent could appeal to developers wary of sending code or credentials to third-party platforms. The reliance on existing coding agents suggests the project is positioning itself as a lightweight integration layer rather than a standalone AI product, which may lower adoption barriers for teams already using these tools.
- Drawgent bridges Claude Code, Codex or opencode to a live Excalidraw canvas for diagram editing.
- It uses the user's own agent installation, login and repo rather than a hosted backend.
- Setup installs ACP adapters and, if necessary, a headless Chrome renderer locally.
