Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare destructiveHint=true and readOnlyHint=false, so the safety profile is known. The description adds genuinely useful scope beyond that: the destruction covers both the intent and its drafts, not just the intent. It still omits whether the action is reversible, what permission level is needed, and what happens to an already-approved intent.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
