Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the tool's simplicity (one parameter, no output schema), the description provides sufficient context: it states the operation, the input limit, the HTTP mapping, and the read-only scope. It does not explicitly describe the return value, but for a 'get full records' tool, this is reasonably implied. The description is comprehensive enough for an agent to invoke it correctly without additional documentation.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
