Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description carries a heavier burden. It discloses that the API key is required and that only the skill owner can query ('스킬 소유자만 조회 가능'), and it mentions the source of the version_id. However, it does not explicitly state whether the operation is read-only or has other behavioral traits, leaving some ambiguity.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
