Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint, idempotentHint, and openWorldHint, so the safety profile is known. The description adds valuable context about the data sources (LinkedIn, BLS benchmarks) and the kind of output (ranked list, risk scores, retention actions), exceeding what annotations alone provide.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
