Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description carries the burden of behavioral disclosure. 'Inspect' suggests a read-only operation, and the purpose adds useful context. But it does not describe the returned structure, what happens if typeName is omitted, or any other behavioral details. The read-only interpretation is reasonable but not fully transparent.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
