Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
The description lacks behavioral details beyond 'cryptographically secure.' It does not explain what the token contains (random bytes), how format and length affect the output, or any side effects. With no annotations, the description carries the full burden and fails to provide sufficient context.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
