Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
The annotations already declare readOnlyHint, openWorldHint, and idempotentHint, covering the safety profile. However, the description adds no behavioral context beyond the one-line statement – no mention of return format, pagination, or scope limitations. With a good annotation set, a score of 2 is appropriate because the description adds minimal value over annotations.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
