Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description carries the full burden of explaining behavior. It discloses that the output is grouped by status, but it does not mention any other behavioral traits such as whether the result is a summary, list, or counts, nor does it describe pagination or ordering. The description is adequate for a simple read-only tool but lacks enriching detail.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
