Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description must cover behavioral traits. It only states 'Get 2FA status' without mentioning authentication requirements, rate limits, or the response format. For a simple GET with no parameters, it still lacks context about potential error conditions or what 'status' entails.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
