Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description must carry the full burden of behavioral disclosure. It only gives a high-level summary ('analyze', 'discover', 'validate') and does not mention potential side effects, external network calls, performance implications, read-only nature, or error behavior. An agent has no idea what happens during execution or what constraints exist, which is insufficient for a complex operation.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
