Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
The description discloses that only warn and error logs are returned, which is a behavioral constraint beyond the input schema. With no annotations provided, the description carries full burden, but it omits other behavioral details like read-only nature, error handling, or pagination. The inclusion of log level is minimally adequate.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
