Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries the full burden of behavioral disclosure. 'Get' implies a read operation, but the description doesn't mention error handling (e.g., 404 if not found), authentication requirements, or what the response contains. Given no output schema, this is a significant gap for an agent to know what to expect.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
