Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are present, so the description bears full responsibility. It only mentions 'using LLM' but fails to disclose whether the tool is read-only, destructive, or requires permissions, nor does it explain what 'checking' entails (e.g., does it modify anything?).
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
