Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries the full burden of behavioral disclosure but fails entirely. It doesn't indicate whether this is a read-only operation, if it requires specific permissions, what the output format might be, or any side effects. For a security tool that likely queries sensitive directory data, this lack of transparency is critical.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
