Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already indicate readOnlyHint and openWorldHint, and the description is consistent with these (a read operation). It adds context by specifying the data scope (financial and lifecycle data), but doesn't go further to explain potential errors, permissions, or response format. The added context is minimal but non-contradictory.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
