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 does disclose the important behavioral detail of using the KMU #55 standard, which clarifies the transformation rule. However, it does not describe the output format, edge cases, or the role of the locale parameter in the response, leaving some behavioral aspects opaque.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
