Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the tool's moderate complexity (1 parameter, read-only operation), no annotations, and the presence of an output schema, the description is complete: it covers purpose, usage, parameter semantics, return values, and behavioral context, leaving no significant gaps for an agent to understand and invoke the tool correctly.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
