Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are supplied, so the description carries the full burden. It says nothing about what the tool actually does at runtime, whether it produces a prompt, a review, or a document, whether anything is persisted, or how output is shaped. The only behavioral claims ("no setup", "works in any LLM chatbot") are promotional rather than operational.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
