Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations indicate read-only (readOnlyHint: true), which is consistent with the description. However, the description adds no behavioral details beyond that (e.g., does it return file paths? contents?). With annotations present, the description provides minimal added value.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
