Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnly=true, idempotent, non-destructive, closed-world, so the safety profile is covered. The description adds real context beyond them: the result set is split into soon-to-enter-into-force acts, recently passed acts, and Sejm bills, and content includes plain-language summaries. It does not mention freshness, caching, or that only Polish law is covered beyond the implicit source names.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
