Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries the full burden. While 'rename' implies a mutation, the description does not disclose potential side effects (e.g., whether references to the style are updated), reversibility, permissions, or return value. This is a significant gap for a write operation.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
