Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries the full behavioral burden. "Ripple-delete" usefully signals that downstream timeline content shifts, but the description does not state that the operation is destructive/irreversible, what permissions are required, or what happens to effects or overlays on the removed clip.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
