Diagnose TermCanvas agentmux nodes that fail to appear and terminal canvases that become janky, resize repeatedly, or show corrupted/unreadable xterm text as terminal count grows, plus duplicate terminal views created after a release relaunch. Use when a child agent is missing, restored terminals duplicate or move to the wrong canvas, a folderless canvas stops syncing, UI or TUI redraws recur every few seconds, WebGL glyphs degrade, or a smoke probe reports no text.
Manage TermCanvas agentmux agents on a canvas. Use this whenever the user wants to inspect a TermCanvas canvas, operate the agent graph, spawn child agents, connect agents, delegate with ask, send prompts, read logs, stop or delete agents, understand AGENTMUX_* session state, or operate TermCanvas as an agent control plane from Codex, Claude Code, OpenCode, Cursor, or another coding agent.
