Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are supplied, so the description carries the full behavioral burden, yet it does not disclose what the tool does internally, whether it mutates anything, what permissions or setup are needed, or what the response looks like. Claims such as "No setup, works in any LLM chatbot" are marketing statements rather than behavioral disclosure.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
