Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries the burden of behavioral disclosure. It states what is exported and the output format (JSON snapshot), which implies a read-only operation. However, it does not mention potential side effects, size limitations, or whether sensitive data (e.g., credentials) is included. This is adequate but not rich.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
