Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description bears full responsibility for behavioral disclosure. It only states 'Test the connection' without revealing whether it is read-only, whether it requires valid credentials, what happens on success or failure, or any side effects. This lacks sufficient transparency for an AI agent to predict tool behavior.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
