Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries full responsibility for behavioral disclosure. It reveals that the tool scrapes external websites and returns alerts, which is useful. However, it does not mention potential side effects such as network rate limits, authentication requirements, or error handling, leaving some uncertainty about operational constraints.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
