Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
For a simple zero-parameter list operation, the description is largely complete: it states what is listed and what is intentionally omitted. However, with no output schema, it does not specify the shape or fields of the returned profile list, which would further help an agent reason about the result.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
