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 notes that closing can be done without rating, but it does not disclose any side effects (e.g., whether closing is irreversible, whether it notifies the other party, or whether the ticket becomes read-only). For a mutation tool, 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.
