Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries the full burden for behavioral disclosure. It explicitly states that the tool will close the browser and clean up the MCP connection, which is sufficiently transparent about its side effects. It could mention potential data loss risks, but for a disconnect tool this is adequate.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
