Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
There are no annotations, so the description carries the behavioral burden. It adds useful context beyond a simple 'returns text' by specifying that the result includes effective date, verified delegated statutes, appendices, and verified citations, and cautions that citations are not confirmed application. This gives the agent a realistic picture of the returned content, though it does not address edge cases or failure modes.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
