Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries the full burden. It states the effect (clears all row selection) but doesn't disclose whether it's a safe read-only operation or a mutation, whether it affects the underlying data, or what happens if no selection exists. For a tool that modifies UI state, this is a gap.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
