Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the complexity (search tool with many siblings, no output schema, no annotations), the description is insufficiently complete. It does not mention what the tool returns (e.g., location objects with fields like name, address, etc.), how many results, or any pagination or ordering. This lack of context hinders an agent's ability to use the tool effectively.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
