Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the tool has 6 parameters, an output schema, and rich annotations, the description covers the essential context: single-person scope, identifier options, cost behavior, and the bulk alternative. It does not describe the response format, but the presence of an output schema covers that. It also does not explicitly mention the mode escalation behavior (only in the schema), but that is adequately captured in parameter descriptions. For an agent to call this correctly, the description plus schema provides sufficient guidance, with minor gaps in distinguishing from closely related tools like resolve_profile.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
