Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint=true, destructiveHint=false and openWorldHint=false, covering the safety profile. The description adds meaningful value by disclosing that output is redacted ('without tokens, state, arguments or raw errors'), which tells the agent the report is sanitized. However, it says nothing about report size, format, or what it does contain.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
