Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint=true and destructiveHint=false, and the description adds meaningful framing beyond that: it is 'neutral, verifiable,' informational, and explicitly not an endorsement. It also reveals the kind of content the tool returns by listing tax->buyback->burn, renounced contract, burned LP, and fair launch. No contradiction with annotations is present.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
