Add Lycana's MCP address to your agent, or install the Lycana CLI. Then approve the connection in Lycana.
Your agent adds nodes, links, boundaries, and notes. They appear on the canvas as a proposal.

A node can name the folder or file it describes, and subcanvases go as deep as you need. Map the code again after a refactor and the diagram updates in place, without duplicates.
