Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description must carry the burden of behavioral disclosure. It conveys a read-only 'List' operation, but does not explicitly state safety (non-destructive), return format, or any edge cases. The added context about LocationId is useful, but the description remains minimal and does not disclose beyond what the name implies.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
