Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries the burden of disclosing behavior. It states the scope ('all tracks in the project') and the action (unmute), but adds no detail about edge cases, idempotence, or effects on selection. This is adequate for a simple state-change command but not rich.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
