cowart-open-canvas

name	cowart-open-canvas
description	Open the Cowart infinite canvas (tldraw) in Vetta Desktop. Use when the user asks to open, launch, view, or work in the Cowart canvas or wants an infinite canvas for visual planning/image work.

Cowart Open Canvas (Vetta 1:1)

Host mapping

Codex	Vetta
MCP App widget (ui://widget/...)	Activity panel tab with full tldraw App
window.cowartMcp bridge	Plugin installs the same bridge via ctx.fs + conversation.sendPrompt
Canvas files under project	<projectDir>/canvas/ (shared with MCP tools)

Workflow

1. Call plugin tool open_cowart_canvas (opens the Cowart activity tab at max width).
2. Optionally call MCP render_cowart_canvas_widget with projectDir = user workspace to confirm storage paths.
3. Canvas data:

canvas/cowart-canvas.json
canvas/pages/<page-id>/cowart-canvas.json
canvas/pages/<page-id>/assets/
canvas/cowart-selection.json
canvas/cowart-view-state.json

4. User draws/annotates in the panel. Agent uses MCP tools (get_cowart_*, insert_cowart_image, …) for programmatic canvas IO. UI AI actions send follow-up prompts into the active conversation.

Image tools (when UI / user asks for bitmaps)

Intent	Tool
New image	generate_image
Edit / annotation revise	edit_image

Then place with MCP insert_cowart_image. Do not use an imagegen skill.

Constraints

• Never pass the plugin install directory as projectDir.
• Prefer open_cowart_canvas for the interactive UI; MCP tools remain available for agent-side canvas edits.
