Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations mark the tool as readOnlyHint=true, and the description reinforces this by framing the operation as returning a document. It adds useful behavioral context: the output is the same Markdown document served at a known URL, includes all published answers, and each answer contains author, verified OAB registration, and official sources. 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.
