Canvas chat agent

The chat in the sidebar is one agent for the whole project. It edits nodes and, through frame tools, what is inside a frame. The editor’s Chat tab posts to the same thread, so a turn shows in both (ADR 0013).

  • One thread per project and user.
  • It sees what you select. The editor sends the selected frame, selection, playhead and mode; the agent can look at and check the selected frame.
  • Frame tools by name. The agent lists and describes frame tools on demand rather than loading all of them, then calls them through the same runner MCP uses.
  • Comments. @feega in a canvas comment starts the agent on the pinned node.
  • Spending. Generation and some ops use credits. Self-hosted instances have no credit limits (Self-hosting).

Outside agents get the same surface through MCP: the edit ops and view.
