Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations only declare readOnlyHint=false, confirming a mutation, which the description's 'Move' already implies. The description adds nothing beyond that: it does not say whether issues are removed from an active sprint, whether the move is reversible, what permissions are required, or what the response contains. For a mutation with minimal annotation coverage, this is a real gap.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
