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 parameter), rich annotations (covering read-only, idempotent, etc.), and the presence of an output schema (detailed in the Returns section), the description is complete. It explains the purpose, parameters, return values with examples, and behavioral context, leaving no gaps for the 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.
