Status Key Mode
- session — Status is shared across all surfaces in a workspace. A single agent status applies globally. Used by Claude Code.
- surface — Status is per-surface. Each pane tracks its own agent state independently. Used by all other agents.
Notification Support
Agents with notification support emit desktop notifications when:
- The agent completes a task (focus-suppressed)
- The agent needs user input (permission request, question)
Agents without native notification support (Codex, Mistral Vibe, Pi Agent) do not forward desktop notifications through Séance.
Hermes Agent achieves notification parity through custom handlers (llm-complete, approval-request) rather than the standard notification hook.
Antigravity CLI emits its own notifications (permission requests and idle transitions) directly from the status-line callback rather than a hook.
clear_status_on_end
When true, agent status is removed from the sidebar when the session ends. When false (Hermes Agent only), status persists after the session ends because the TUI session may outlive individual agent processes.
