Question

You are building a customer-support assistant that must always log a ticket by calling the `create_ticket` tool at the end of every conversation, regardless of the user's phrasing. During testing, Claude sometimes replies with a plain text summary instead of invoking the tool. Which configuration best guarantees that Claude calls `create_ticket` on the relevant request?

Accepted Answer

Set the `tool_choice` parameter to force use of the specific `create_ticket` tool.

Answer

Set `tool_choice` to `auto` and add more examples to the system prompt.

Answer

Set `tool_choice` to `none` so Claude focuses only on the ticket.

Answer

Lower the temperature to 0 so Claude behaves deterministically.
