Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries the full burden for behavioral disclosure. It only states the download action and leaves important behavior undisclosed, such as whether it returns a direct video URL, saves a file, or fails on non-video notes. This is a significant gap for an operation that could have side effects or output ambiguities.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
