Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
For a simple single-parameter tool with rich annotations and an output schema, the description is sufficient. It explains the core action and the resolution method. Minor omission: no explicit mention of error handling (e.g., when ORI not found), but likely covered by output schema.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
