Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries the full burden of behavioral disclosure. It only states that a scan is executed, but does not mention potential side effects (e.g., intrusive network traffic), permission requirements, output format, or whether it is safe or destructive. This is a significant gap for a vulnerability scanner.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
