new_canvas

Create a moodboard canvas without showing it, and get its canvasId. Fill it, then show it once, finished, with open_canvas.

Plan	Quota	Changes data	Hints
All. Free owns at most 3 boards	Counts toward the canvas limit	Yes	not idempotent

The skills use this instead of open_canvas so you never watch an empty board fill up. They call it only when none of your recent boards fits the request.

Inputs

Name	Type	Required	Limits	What it does
`title`	string	No	1 to 80 characters	Board title. Default: made from the brief, else “Untitled moodboard”
`brief`	string	No	1 to 500 characters	The design brief, saved on the board
`taste`	string[]	No	1 to 5 words, each up to 40 characters	Style words. Searches on this board use them

Example call

{
  "name": "new_canvas",
  "arguments": {
    "title": "Coffee launch page",
    "brief": "launch page for a specialty coffee roaster",
    "taste": ["grainy", "big typography"]
  }
}

Example output

Taste for searches: grainy, big typography.
Next: pass this canvasId to bend_brief and search_references, place results with add_to_canvas, then call open_canvas with this canvasId to show the finished board.
