Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
There are no annotations and no output schema, so the description carries the full behavioral burden. 'Get' suggests a read operation, but the description does not disclose error behavior for missing/invalid UUIDs, whether authentication is required, or what the response contains beyond the specification itself.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
