generate_canvas_image

act imperative

Generates or replaces one AI visual layer for a selected canvas card after the human asks. Inline illustrations and full-card backdrops are stored independently; generating either must preserve the card text, citations, source thumbnails, layout, and the other visual layer. Generated artwork is visibly labeled and never treated as source evidence.

Input schema

Property	Type	Required	Description
`blockId`	string	yes	—
`prompt`	string	yes	Art direction based on the human's comment, card meaning, and canvas mood. Do not ask for text inside the image.
`alt`	string	no	Concise accessible description of the intended image.
`placement`	string	no	Use background only when the human explicitly requests a full-card backdrop; otherwise use inline.
