Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries full burden. It states this is a retrieval operation ('取得します'), implying it's read-only, but doesn't disclose any behavioral traits like authentication requirements, rate limits, error conditions, or what happens if the task doesn't exist. For a read operation with zero annotation coverage, this is insufficient.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
