Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries the full behavioral disclosure burden. It explicitly states the operation is reversible and can be undone, which is the key behavioral trait distinguishing archive from delete. It does not mention permissions or side effects, but for a single-parameter archive action, reversibility is the most important behavioral information.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
