Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare destructiveHint=true, idempotentHint=false, and openWorldHint=true, so the risk profile is covered structurally. The description contributes the ownership requirement ('own track'), which is real context beyond the annotations, but says nothing about what state results after removal or how a missing cover is handled.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
