Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint, idempotentHint and openWorldHint=false, and the description adds real context beyond them: VSO help is free, attorneys/agents may charge after notice of the initial decision under fee rules, and it is not legal advice nor VA-affiliated. It does not disclose pagination or result-ordering behavior, but the added domain caveats are substantive.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
