Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are present, so the description carries the burden. The verb 'List' and 'currently available' convey a read-only behavior and the distinction from historical transitions, but the description does not disclose response format, permission requirements, or edge cases like empty transition lists. It gives moderate behavioral context beyond the name.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
