Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries full behavioral disclosure burden. It indicates this is a test/verification operation (implied read-only) and mentions authentication, but doesn't specify what 'test connection' entails (e.g., whether it validates credentials, endpoint availability, or both), what happens on success/failure, or any rate limits. It provides basic context but lacks operational details.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
