Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description carries the full burden. It discloses the immediate effect (disables auto-paste) and the resulting mode (manual via slash commands), but it omits potential side effects, reversibility, or any prerequisites. Since this is a simple toggle, some inference is reasonable, but more explicit detail would improve transparency.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
