Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries full burden. '정의합니다' (defines) implies a creation/mutation operation, but the description doesn't disclose what happens to the original object (is it replaced? modified? copied?), whether this requires specific permissions, what happens on failure, or what the result looks like. For a mutation tool with zero annotation coverage, this is inadequate behavioral disclosure.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
