Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint, openWorldHint, idempotentHint, and destructiveHint=false, so the safety profile is clear. The description adds useful detail about what data the tool reports, but it does not disclose behavioral aspects such as whether it queries live pub.dev data, possible latency, or how missing packages are handled. This stays at the calibrated baseline for annotation-covered read tools.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
