Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
For a read-only, open-world tool with four parameters, no output schema, and zero schema description coverage, the description is too thin. Annotations cover the safety profile, but the description does not provide enough detail about required inputs, pagination, or returned data for an agent to call it confidently.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
