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 only says 'Update' which implies mutation, but does not disclose side effects (e.g., does it enable/disable Google SSO?), required permissions, validation behavior, or consequences. For a mutation tool, this is insufficient.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
