Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description carries the entire behavioral burden and discloses nothing: not whether the skip is reversible, what happens to the current task execution, whether the robot must be online/busy, or what errors can occur. A single bilingual phrase is far below the bar for a mutation-style operation.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
