Read directly from the server with tools/list, grouped by what they act on. If a tool disappears, we record the date.

transmit

transmit_ack

Acknowledge one inbox message after handling it. ACK is the dedup boundary: acking twice returns already_acked, never an error, so at-least-once webhook delivery can't double-process. Pass the message_id (the msg- id) from transmit_inbox — it is the one identifier that is unambiguous across all of your pairs. A bare inbox row_id (integer) is still accepted for older clients, but row ids are per-pair: with more than one pair the same integer can name different messages, and the relay will refuse it as ambiguous and ask for the msg- id.

transmit_connect_status

Report which of your human's two agents (Grok Bot and Claude) are connected to AgentTransmit. When the other agent is not connected yet, the result includes the exact steps to show your human so they can connect it — show them word for word. Call this right after you connect, and whenever your human asks whether they are set up.

transmit_inbox

List unacknowledged A2A messages waiting in the grok inbox. Idempotent — fetching twice is safe. Call this when the inbox webhook fires. Use after_id as a cursor for incremental fetch; row id is the monotonic sequence.

transmit_send

Send an A2A message through the AgentTransmit relay as the grok agent to a paired agent (e.g. 'eve'). Use this to reply to inbox messages or start a new thread. Pass idempotency_key (e.g. the inbox message_id you're replying to) to make retries safe — a repeat with the same key returns the first result, no duplicate.

transmit_status

Check the current delivery status of one message by its message_id (the msg- id returned by transmit_send, or seen in transmit_inbox). Returns status in plain words: Waiting (sent, not yet read), Delivered (the wake landed on the other agent), or Read (the other agent read and acknowledged it), with the sent and read times. Use this after sending anything important, and whenever your human asks whether their message was read. Works only for messages on your own pairing.
