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 discloses the cascade delete behavior, which is critical, but doesn't mention other behavioral traits like permissions required, whether deletion is irreversible, error conditions (e.g., if group doesn't exist), or response format. For a destructive tool with zero annotation coverage, this is a significant gap.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
