Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries the full burden. 'Fetch' plus the enumerated read-only payload (description, ai_usage, features, pricing, certifications, links) makes the read-only nature clear and characterizes the response. However, it says nothing about behavior on an unknown/expired slug, permissions, or rate limits, which matters for a tool with zero annotation coverage.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
