- description: "Sends a prompt to one of your interns and streams the reply as OpenAI-compatible server-sent events ending with `[DONE]`. The run executes on the intern, which may pause to ask you something. It then streams one `openrouter.provide_input` tool call and finishes with `finish_reason: \"tool_calls\"`, and the run stays open on the intern.\n\nEvery response, whether it ends with `stop`, `tool_calls` or `error`, is followed by a final chunk with empty `choices` that carries `session_id`, then `data: [DONE]`. That chunk carries the `usage` the intern reported for the run, after `stop` or `error`, and `null` when the intern reported none. After `tool_calls` its `usage` is `null` because the turn is not over. Read through `[DONE]`: the `session_id` you need to reply arrives after the `tool_calls` finish chunk.\n\nTo answer, send a second request with the same `session_id`, the assistant message echoing that tool call, and a `tool` message whose `tool_call_id` is the tool call id and whose `content` is the answer. The answer is delivered to the run that asked and the stream continues from where it paused. A question stays open for its interaction deadline (5 minutes by default) and the run is cancelled when that passes. Rejected replies do not extend the deadline.\n\nClosing the connection after the `[DONE]` that follows `finish_reason: \"tool_calls\"` keeps the run alive. Disconnecting while a response is still streaming cancels the run. The disconnect is noticed when the intern next writes to the stream, which during a silent tool run can take more than one 30 second heartbeat interval.\n\nA run the intern ends while you are still connected, by cancellation or by a deadline, ends the stream with a `finish_reason: \"error\"` chunk carrying `410` and reason `run_ended`, then the final empty-`choices` chunk and `[DONE]`. That error reports only an ending the intern confirmed. A connection that breaks without that confirmation ends with reason `stream_severed`, and a client that has already disconnected is promised no final event.\n\nSet `approval_mode` to `manual` to have the intern ask before approval-bearing tools such as the shell. Omitted, the run self-drives and consents on your behalf. The mode belongs to the run started by that prompt and must be repeated on later prompts.\n\nAvailable to interns programme members. Callers outside the programme receive `404` for every path under `/api/v1/interns`."
