Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries the full burden, yet it only restates the purpose. It doesn't say what a negative result looks like, whether it requires Premiere to be running, whether it blocks or errors, or whether it is a cheap local check. Nothing behavioral is disclosed.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
