Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are present, so the description carries the full burden of behavioral disclosure. It only states 'Delete a ticket group,' which implies destructive action but does not specify irreversibility, side effects on associated tickets or events, permissions required, or what the output represents. For a destructive tool, this is severely inadequate.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
