Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are supplied, so the description carries the full disclosure burden, and it says nothing about return shape, ordering, or whether clips overlapping versus starting at the time are included. "Under a given time" is ambiguous about whether it means clips at/before the time, spanning it, or beginning there. Read-only nature is only implied by the get_ prefix.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
