Render any board content you compose from native primitives. Provide elements (shape, sticky, frame, text, connector); the server owns ids and styling, but YOU own the layout — give explicit x/y/width/height so nothing overlaps. LAYOUT RULES: (1) Stickies are ALWAYS square; the side equals the width you send (height is ignored), so reserve a square footprint and leave >=40px gaps between boxes. (2) Lay diagrams out on a clean grid (left-to-right or top-to-bottom) and connect adjacent boxes; do NOT place any shape on the straight line between two boxes you connect, or the arrow will cross it. (3) For a branch/decision, offset the branch target to the side or below with clear space so its connector has an empty corridor — the server routes arrows from the nearest edges with elbow bends, which only stays clean when you leave room. Use this for anything that does not fit a named template. THINKING SIGNAL: when you START handling the user's request, call this once with empty elements: [] so the board shows your cursor 'thinking'; then call it again with the real elements once you have composed the answer.

Apply a named, adaptive template (cjm, swot, raci, retro, bmc, kanban). You provide the structure (lanes and stages of any size); the server owns the layout and inherits the preset style. The grid grows to fit your content. Call with { list: true } to see available templates and their structure.

Manage board pages: list available pages, create a new one, or switch the active page. Returns pages, the active page id and the current session binding.

Read the canvas and return a text summary. Scope: image (images on the page), page (the whole page), or selection. Does not modify the board.

Revert the last AI batch of the active runtime session.
