Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description carries the behavioral burden and does it reasonably well: it discloses the analytical nature of the tool, the specific verification dimensions considered, and the output shape ('flags + verdict'). It does not detail side effects, auth, or exact flag semantics, but the tool appears to be a read-oriented verification service, and the disclosure is meaningful beyond the tool name.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
