Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries the full burden of behavioral disclosure. It only says 'Remove an animation tag by name' without mentioning whether removal is permanent, what happens to frames associated with the tag, or how errors (e.g., missing tag) are handled. This is insufficient for a mutating operation.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
