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 return type ('단계별 설치 가이드 문자열') but does not mention potential errors, permissions, or side effects. For a simple getter, this is somewhat adequate but lacks edge-case transparency.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
