Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries full burden for behavioral disclosure. It states what the tool checks but doesn't describe how it performs these checks, what permissions are required, whether it's read-only or has side effects, what the output format is, or any rate limits. For a diagnostic tool with zero annotation coverage, this leaves significant behavioral gaps.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
