Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
The readOnlyHint annotation already indicates this is a safe read operation. The description 'List indexers' aligns with this, but adds no additional behavioral context such as pagination, ordering, or output format. Since the annotation covers the primary safety aspect, this is adequate but not enhanced.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
