Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description must convey behavioral traits. It states only that the tool gets settings, a common read operation. However, it does not disclose the return format, potential cost or restrictions, or what happens if no grid settings exist. The lack of output schema amplifies the need for more behavioral context.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
