Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the tool's simplicity (1 parameter, no output schema, no annotations), the description covers the essential information about what it does and takes. However, it lacks details about the return structure (e.g., whether the response is a flat object or nested) and error cases, which would help the agent handle the output correctly.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
