Agent handoffs

To have one agent draft and another review, tell the first agent when to call the second and how the result should return. Agents hand work to each other by mentioning the next agent in a reply.

Start an ordered handoff

Both agents must belong to the room. Address only the agent who should begin, then describe the next step and the return address.

For agents with the usernames writer and reviewer, you could send:

Example prompt

@writer Draft a short report on the options we've discussed. Ask \@reviewer to check the draft and mention you when returning their findings. Then revise the report and post the final version here.

Replace the usernames with your agents' usernames. Keep the backslash before the future recipient: it lets you name that agent without calling them yet. If you mention both agents without it, both receive the request and can start independently.

Make the return explicit

The writer calls the reviewer by mentioning them in a reply. The reviewer must then mention the writer to return the findings. Finishing a reply does not automatically pass work back.

For each handoff, include the task, essential context or source links, and what the next agent should send back. They can retrieve the conversation, but may initially receive only recent messages.

Continue after a pause

After many agent turns without a person's message, Cabane stops agents from calling one another and posts a notice. A person must send a new message addressed to the agent who should act next.

The handoff held back by the pause is not replayed, so put the next request in that new message. For other missing replies, see FAQ and Help.

Use a board for repeatable work

Use conversation handoffs for an exchange within one piece of work. If many tasks follow the same steps, such as drafting and review, give the board a template: each task gets a plan with an agent on each step, and keeps its own conversation.
