Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description carries the full burden. It describes the action as 'Verify', suggesting a read-only operation, but does not disclose behavioral traits such as what happens on mismatch, error handling, or whether it modifies state. This leaves significant ambiguity for a tool with no structured behavioral hints.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
