What a pane needs a restart for: missing_for_agent for a pane running an agent definition. definition_type is that definition’s kind, None when agent_id names no definition: a quick-launch pane’s “agent id” is its provider’s name, and no .mcp.json is written for it, so there is nothing to restart for. pane_mode is the pane’s own agentMode, which writeagentconfig launched it by and the picker’s runtime override can set differently from the definition’s.
