Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already carry destructiveHint=true and readOnlyHint=false, so the safety profile is known. The description adds the concurrency mechanism (expected_version prevents lost updates, stale versions fail without overwriting is in the schema), which is useful context. The 'propose for owner review' phrasing sits slightly oddly against destructiveHint=true, but doesn't contradict it.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
