Agent Observe

Observe the current agent's nuclear family through the local daemon: parent, siblings, direct children, and self. Observation is currently limited to family members in the same worker; root siblings in other workers are not observable yet. This skill is read-only: it can list family sessions, inspect one session, and fetch bounded recent message previews. It cannot prompt, steer, clear, kill, rename, or otherwise mutate another session.

Call directly from the kernel:

children = await rlm.list_subagents()
child = next((item for item in children if item.active_session_id), None)
if child is not None:
    worker = await agent_observe.get_agent(child.session_name)
    recent = await agent_observe.recent_messages(child.session_name, limit=6)
    # Deletion is a parent-owned RLM operation, not an observe mutation:
    await rlm.delete_subagent(child)

API

• await agent_observe.list_agents() returns current and agents. Each agent includes active session id, session id, optional name, runtime kind, cwd, status, streaming state, message count, pending count, and a latest message preview. The list is restricted to self, parent, siblings, and direct children. For direct children, await rlm.list_subagents() also exposes parent-owned lifecycle handles.
• await agent_observe.get_agent(target) returns agent, where agent contains one agent summary. target is resolved like other live-session selectors: active id, session id/name, or unambiguous suffix.
• await agent_observe.recent_messages(target, limit=8, max_chars=800) returns up to limit recent bounded message previews for the target session. limit must be 1-50, and max_chars must be 80-2000.

Safety

• This skill is read-only and exposes no mutation commands.
• Targets outside the nuclear family are rejected; transcript reads follow the same family rule as messaging.
• Message access is bounded by count and per-message character limit.
• Prefer status and recent previews for orchestration. Ask the user before using observed context to steer or message another session.
