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 states 'Get studies' which implies a read operation, but doesn't disclose behavioral traits such as authentication needs, rate limits, pagination, or what 'studies' entails (e.g., format, scope). This is inadequate for a tool with no annotation coverage.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
