tldraw offline Skill

Work with the tldraw offline desktop app (offline.tldraw.com): read the open canvas, make edits, and write document scripts — JavaScript embedded in a .tldraw file that runs on load and gives the file durable behavior. The app runs a local HTTP API (default localhost:7236) that a coding agent drives with plain curl from its terminal — this is exactly how the app's own homepage demo (Codex editing a canvas live) works. The agent does NOT use computer-use / GUI clicking, and does NOT hand-edit the .tldraw file directly. Keep tldraw offline open while you work.

When to Use

• The user has tldraw offline open and asks you to build or modify a canvas (diagrams, wireframes, layouts).
• You want to add durable behavior to a drawing (reactive shapes, interactive buttons, animation, connection logic) via an embedded document script.
