Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description carries the full burden. It explains the process (vetted human expert), the types of errors checked (hallucinations, factual errors, weak parts, domain mistakes), and expected outputs (verdict, issues, improvements, certificate). It does not cover costs, rate limits, or turnaround time, but for a human-review tool, it provides sufficient behavioral insight.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
