Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the low complexity (zero parameters, no nested objects, no annotations) and absence of an output schema, the description compensates adequately by enumerating the specific fields returned (trust score, tier, orientation, domains, stats). This gives the agent sufficient context to understand what data will be available without over-specifying. It appropriately handles the 'your' possessive to indicate this returns the authenticated agent's own data.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
