Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint=false, destructiveHint=true, idempotentHint=true, and openWorldHint=false. The description adds useful context beyond annotations by stating that the research result stays retrievable with get_research, clarifying that stopping updates does not delete the result. It does not address permissions or notification behavior.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
