Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already flag destructiveHint=true and idempotentHint=false, and the description goes well beyond them: it discloses replace-collection semantics (omitted sections are deleted), that section IDs and comment anchors survive, that the write is atomic at the supplied revision, that stale revisions fail without writing, that edits touching pending review changes fail, that detached discussions are reported, and the required write consent and Strategy management rights. This is exactly the extra context a destructive mutation needs.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
