Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries the behavioral disclosure burden. It explains the ranking methodology (ProofMark: third-party testing, certifications, quality metrics), which adds useful context. However, it does not disclose return format, edge cases (e.g., empty results), or any potential limitations, leaving some gaps for a tool without an output schema.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
