Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description is the sole source of behavioral information. It explains the functional effect (spam delivered to separate folder) but does not disclose potential side effects, reversibility, or whether existing spam is redistributed. This is adequate for a simple toggle but lacks depth.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
