Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries the disclosure burden. It implies a safe read-only listing and communicates scope ('all available assets'), but it never states that it is read-only, whether pagination applies, or what the result looks like. For a zero-parameter list call the risk is low, so this is adequate but thin.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
