Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are supplied, so the description carries the full disclosure burden, yet it reveals nothing about behavior: not whether the tool reads or mutates state, not what the "check" evaluates, not what the response contains, and not whether it depends on external data. Phrases like "production-ready" and "copy-paste prompt pack" are marketing claims, not behavioral facts an agent can act on.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
