Agent Message

Send direct messages within the current agent's nuclear family through the local daemon: parent, siblings, and direct children only. Roots are siblings. The daemon derives your sender identity from the current session; do not try to include a from field.

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:
    receipt = await agent_message.send(
        "Please inspect the latest result.",
        receiver_role="child",
        receiver_name=child.session_name,
    )
    # Keep the child until this follow-up finishes so its result remains observable.

API

• await agent_message.list_agents() — returns current (name, id, depth) and family-scoped entries (relationship, name, id, depth, status) for the current agent's parent, siblings, and children. It includes inactive family members and sorts parent, siblings by name, then children by name; it does not expose a global daemon session list.
• await agent_message.send(message, receiver_role="parent" | "sibling" | "child", receiver_name=None) — sends one direct text message to an active session. Sending to an idle completed subagent starts an ordinary follow-up turn in that same child session and context. The child remains available only until its parent session closes. The daemon resolves receiver_role within the current agent family; receiver_name is required for siblings and children and omitted for the unique parent. send("all", message) broadcasts only to the family roster and returns {receipts: [...]} in roster order; successful entries are ordinary receipts and failed entries contain the target id and a short error. One failed delivery does not reject successful deliveries. Messages always use steering delivery so a busy target sees them during its active run. Returns a receipt with a deliveryStatus field: "delivered" means the message reached an idle target's context; "queued" means a steering message was accepted and will deliver when the target's current work allows (send does not block waiting for that). Delivered receipts carry deliveredAt, queued receipts carry queuedAt.

Safety

• Do not delete a child immediately after send: delivered follow-ups may still be running and queued receipts have not run yet. Wait until observation shows the child is idle and its context is no longer needed before calling await rlm.delete_subagent(child).
• Reach is limited to parent, siblings, and direct children; relay through an intermediate child instead of messaging grandchildren or cousins directly.
• Sender identity is daemon-derived and cannot be spoofed from Python.
• The daemon enforces message size, rate, and pending-queue limits before accepting delivery.
