Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are supplied, so the description carries the full behavioral burden. It says the selection is cleared but does not disclose prerequisites such as whether an active sequence is required, what kind of timeline selection is affected, or what happens when nothing is selected.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
