Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries the full behavioral disclosure burden. It reveals only that an effect is removed, but not the scope (selected clip, all clips, or sequence), failure behavior, or whether this is destructive in a way that requires confirmation. This is a significant gap for a mutation operation.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
