Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations exist, so the description carries the full disclosure burden. 'Get' implies a non-mutating read, but nothing is said about error behavior for an invalid or expired trigger id, what fields are returned, or whether the GTT must be in a particular state.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
