A teammate asks why your Claude agent’s tool definitions contain detailed descriptions even though the tool names are already descriptive. They propose removing those descriptions to make the tool definitions simpler. How would you reply?
A Agree with the teammate because tool names are sufficient for the model to choose the right tool on every request the agent handles. B Explain that the model uses the tool description to decide when to call the tool, and descriptions disambiguate cases where the tool name is not enough. C Suggest moving the descriptions out of the tool definition and into a separate documentation file the team maintains so the tool definitions stay short and the descriptions remain available. D Suggest replacing the descriptions with example calls embedded in the tool definition, treating example calls as a complete substitute for the prose description. Show Answer Answer Explanation Claude uses a tool’s description to understand what the tool does, when it should and should not be called, and how its parameters affect behavior. Detailed descriptions provide context that tool names cannot reliably express, helping Claude distinguish between tools and select the appropriate one. Anthropic identifies detailed tool descriptions as a key factor in tool-use performance.
