Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint=true, destructiveHint=false and openWorldHint=false, so the safety profile is covered. The description adds a useful liability boundary ('Informational, not advice') and signals that the payload is a multi-factor doctrinal position rather than a single number. It adds no auth, rate-limit, or coverage-limit context beyond that, which is acceptable but not rich given annotations already carry the operation semantics.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
