Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
For a read-only analytics tool with a full input schema and an output schema, the description adequately covers purpose, scope, and access level. It does not elaborate on behavioral edge cases, but the structured fields already carry parameter details, so nothing critical is missing for a correct call.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
