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 and largely fails it. It never says what invoking the tool actually returns (a prompt? a playbook document? generated copy?), whether it is read-only or generative, or what the optional query does to behavior. Only the throwaway "no setup, works in any LLM chatbot" hints at operational behavior.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
