Question

You are building a travel assistant with Claude. For a single user request, Claude needs to look up the weather for three different cities before making a recommendation. The three weather lookups are completely independent of one another and use the same tool with different inputs. How should you handle this to minimize total latency?

Accepted Answer

Allow Claude to request all three weather lookups as parallel tool calls in one response, then return all three tool results together in the next user message.

Answer

Force Claude to make the three lookups sequentially, returning each result before it can request the next city.

Answer

Disable tool use and ask Claude to estimate the weather for all three cities from its training data.

Answer

Combine the three cities into a single tool description so Claude only needs to call the tool once with no arguments.
