Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description carries the full burden and discloses the dual toggle behavior. It also includes a cautionary instruction to confirm with the user, hinting at the potential impact of stopping a live stream. However, it does not mention specific side effects, permissions, or reversibility, but the confirmation instruction adds meaningful context.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
