Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint=true, idempotentHint=true, openWorldHint=false, and destructiveHint=false, so the safety profile is covered. The description adds that the payload is 'condensed' (as opposed to a full profile) and enumerates what it includes, which is useful context, but it says nothing about size limits, whether defaults are applied, or how the 'next-tool prompts' behave.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
