Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
For a parameterless, read-only list endpoint, the description is mostly complete: it gives the endpoint, scope, and category. However, there is no output schema and the description does not describe what the response contains, which could leave an agent unsure about the returned account shape. It also does not contrast with account-specific sibling tools, so some selection context is missing.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
