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 discloses the core state-changing behavior ('Reopen a previously closed board/sprint') and the precondition ('previously closed'). However, it does not mention idempotency, error handling for already-open boards, permissions, or side effects, which leaves some behavioral gaps.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
