Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the tool's low complexity (1 optional parameter), rich annotations (read-only, idempotent, non-destructive), and no output schema, the description is minimally adequate. It covers the basic purpose but lacks details on usage context, parameter implications, or behavioral nuances, leaving gaps for an agent to infer correct invocation.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
