Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries the burden of behavioral disclosure. It mentions 'returns compact records, best match first', which gives some insight into return format and ordering. However, it does not disclose any side effects (likely read-only) or pagination details. A search operation is typically safe, but without annotations, more explicit confirmation would be helpful.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
