Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint=false, destructiveHint=false, idempotentHint=false and openWorldHint=false, so the safety profile is covered. The description adds no behavioral context beyond the bare action — it does not say which window or session receives the keypress, whether focus must be established first (e.g., via minimax_activate), or what happens if the target is not focused.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
