Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries full responsibility for behavioral disclosure. It only hints at validation logic ('using rules parsed from the repository') but does not describe side effects, error states, permissions required, return behavior, or any constraints. This is insufficient for a mutation-like operation.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
