Widget panel
Use show_widget with presentation.target: "node_panel" to create a hosted widget document and present it on an eligible connected Mac. This is the normal agent path.
The Canvas tool is limited to direct panel control:
present: show the panel, optionally with a hosted document path or local app scheme.hide: hide the panel.navigate: navigate the visible panel to a hosted document path or local app scheme.
Do not invent local file paths or arbitrary external URLs. Use HTML widgets with show_widget; hosted documents use the capability-scoped /__openclaw__/canvas/documents/... route it returns.
If plugins.entries.canvas.config.host.enabled is false, hosted widget documents and node-panel presentation are disabled together.
