Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint=true, idempotentHint=true, and destructiveHint=false, so the safety profile is covered structurally. The description earns credit by disclosing the payload's depth and contents (full vs trimmed), which is meaningful behavioral context the annotations cannot convey. It does not mention rate limits, auth requirements, or pagination, keeping it below a 5.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
