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 mentions retrieving 'account information including balance and metadata', which implies a read-only operation, but does not disclose behavioral traits such as permissions required, rate limits, error handling, or what specific metadata is returned. 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.
