Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations provided, so description carries full burden. It states 'Fetch' which implies a read-only operation. However, it does not disclose potential errors (e.g., case not found), permissions required, or rate limits. For a simple fetch, this may suffice, but more context would improve transparency.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
