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. It implies a read-only listing operation, which is non-destructive and simple, but it does not explicitly state side-effect-free behavior, pagination, or any filtering semantics beyond the optional limit. For a low-risk read operation, this is adequate but minimal.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
