Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint/idempotentHint/destructiveHint=false, so safety is covered. The only behavioral hint is 'deep проверяет STEP', which implies a heavier check mode, but the description says nothing about cost, failure modes, or what a 'timeline health' result means.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
