Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations only say readOnlyHint=false, openWorldHint=true, idempotentHint=false, destructiveHint=false. The description adds what those hints cannot: the tool makes bounded public HTML requests (open-world network scope), requires a paid/trial slot plus explicit authorization, writes candidate facts with source receipts, and preserves existing draft content. It also explicitly disclaims AI scanning and publishing, so no contradiction with the annotations.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
