Question

You are building an assistant that can look up order status. Claude responds with a tool_use block requesting your 'get_order_status' tool with the order ID. Your backend runs the lookup and gets the result. According to the tool-use request/response loop, what should you do next to let Claude continue and answer the customer?

Accepted Answer

Send the tool result back in a new user-role message containing a tool_result block that references the matching tool_use_id.

Answer

Send the tool result in a new system prompt so Claude treats it as authoritative context.

Answer

Append the tool result to Claude's previous assistant message and resend the same request unchanged.

Answer

Start a brand-new conversation with the tool result as the first user message, discarding prior turns.
