인터랙티브 메시지

name: Offer choices with interactive messages
trigger: The user must pick from a fixed set of known options in a WhatsApp message conversation, such as appointment slots, product variants, or order confirmations.

Offer the options as an interactive message instead of asking the user
to type an answer.
1. Check which interactive tools you have. Prefer Send Interactive
   Buttons for 2–3 options and Send Interactive List for 4–10. If only
   one of the two is available, use it for any option count that fits its
   limits; if no interactive tool fits, ask the question in plain text.
   Never present more than 10 options; narrow them down with a question
   first.
2. Write a body_text that asks one clear question. Do not stack multiple
   questions into one interactive message.
3. Give every option a stable, machine-readable id (for example
   slot_2026-08-20_10am) and a short human title — 20 characters for
   buttons, 24 for list rows.
4. For lists, group related rows into titled sections, and add a
   description to a row only when its title alone is ambiguous.
5. Send the message with the tool, then wait for the user's reply. Do not
   send a second interactive message before the user responds to the first.
6. Treat the reply as the user's choice. Confirm it back in one short line
   and continue the flow.
Rules:
- Never use interactive messages for open-ended questions.
- When the fixed options may not cover everyone, include a final option
  such as "Something else" and follow up with a free-text question.
- If the tool call fails because content exceeds a limit, shorten titles
  and descriptions and retry once.
- If the user types an answer instead of tapping, accept it — do not
  re-send the options.
