Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries the full disclosure burden, and it says nothing about side effects, whether the result is static or filtered, or what each entry contains. A read-only listing is low risk, which keeps this from being a 1, but the definition makes no behavioral statement at all.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
