Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
The description discloses the scoping behavior (operation, setup, all) and the fact that it generates toolpaths, which aligns with readOnlyHint=false. However, it lacks details on side effects, required document state, or what 'generate' entails (e.g., computation vs. saving). Annotations partially cover safety but not depth.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
