Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description carries full burden but only mentions the basic toggle function. It does not disclose behavioral traits like dry_run simulation, confirm safeguards, or side effects of enabling/disabling UPnP (e.g., automatic port forwarding).
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
