Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description carries the disclosure burden. 'List' implies read-only and the track-filtering behavior is stated, but the description does not specify return structure, ordering, or behavior when no clips exist. This is a simple list operation with no destructive side effects, so the omission is moderate.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
