Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the tool's simplicity (1 parameter, no output schema, no annotations), the description is incomplete. It doesn't explain what 'detailed information' includes (e.g., contact info, listings, performance metrics), which is crucial for an agent to understand the return value. With no output schema, the description should compensate by outlining expected data, but it fails to do so.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
