Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description must disclose behavioral traits. It only notes the repost must have been 'previously shared', implying an ownership/precondition, but does not mention authentication requirements, idempotency, effects on the original post, or error behavior. This is insufficient for a mutation tool.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
