Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With destructiveHint=true already present in annotations, the description merely restates the action ('Delete') without adding any context such as irreversibility, cascading effects, or whether special permissions are required. It does not contradict annotations, but provides zero additional behavioral insight beyond the structured data.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
