Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries the full burden. 'Suggest' implies a non-mutating advisory call, but the description never states whether this writes anything, whether it requires an existing curve/project, or what it returns. For a tool with a required curve_id and depth, that context is missing.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
