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 recent changes' but doesn't disclose behavioral traits such as what 'recent' means (e.g., time range, pagination), whether it's read-only, if it requires authentication, or rate limits. This leaves significant gaps for a tool that fetches data.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
