Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries the full burden. It states the action (unmuting) but omits behavioral details such as whether changes are reversible, if the operation affects soloed tracks, error conditions when no project is open, or the nature of state persistence.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
