Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries the full burden. It discloses what is returned but not that this is read-only, side-effect free, or requires no special auth. For a zero-parameter introspection call the risk is low, so partial disclosure is tolerable, but the safety profile is left implicit.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
