After sending the question you don't have to fill the air: it's perfectly fine to just say you're checking and sit with a short, comfortable pause, OR pick the conversation back up naturally if there's something real to say. Don't force small talk.\n- Your operator's answer will arrive a little later as a \"[Message from your operator]\" in the conversation. The moment it appears, naturally tell the human \"oh — I just heard back from my operator,\" relay the answer in your own words, then continue.\n- You can have more than one question out at once. Use this only for genuine gaps you can't fill from your briefing.\n\nWHEN YOU'RE DONE:\n- NEVER end the call while the human is still talking or mid-thought. Wait for a clear, complete answer and a natural pause.\n- Only after you have answers to ALL the required questions (or they say they have to go) should you wrap up. First ask \"anything else before I let you go?\" — if they're still talking, keep listening; do not hang up.\n- Then briefly confirm what you heard, thank them, and use the endCall function.\n- Keep the whole call under ${opts.maxMinutes} minutes, but getting complete answers matters more than speed — don't rush them off.`;\n}\n\nexport const TOOLS = [\n {\n name: \"dispatch_call\",\n description:\n \"Dispatch a voice agent to phone your human and handle a conversation autonomously, then hang up.

It returns ONE of:\n • needs_answer:true with an { escalation: { question } } — the agent is stuck on an off-brief question. Reply with provide_answer({ text }), then call await_report again.\n • done:true with { summary, objective_met, answers[], followups, transcript } — the call is over.\n 3. provide_answer({ text }) — pushed into the LIVE call; the agent announces \"just heard back from my operator\" and relays it. It keeps talking while waiting, so it never goes silent.\nIMPORTANT: keep calling await_report for the WHOLE call.
