Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
For a tool with one parameter and an output schema present, the description is minimally sufficient but lacks any mention of error conditions, prerequisites (e.g., resource must have a UID), or the nature of the return value. The annotations cover safety, and the schema covers parameter details, but the description does not address potential failure modes or clarify the expected output beyond the name. Given the simplicity, a 3 is fair—it is not inadequate but leaves room for improvement.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
