Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the tool's moderate complexity (batch operation with one parameter), rich annotations (covering safety and idempotency), and the presence of an output schema (returns str), the description is complete. It explains the action, performance, parameters, and return value, leaving no gaps for agent understanding.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
