Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are present, so the description carries the full burden. It says 'consolidates' but does not clarify whether this deletes duplicates, is reversible, requires user confirmation, or has any side effects. The term 'consolidate' is ambiguous and could imply destructive actions.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
