Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries the burden. It discloses the type of information returned (fingerprints, publish timestamps, exit addresses), which adds some behavioral context. However, it does not explicitly state that the tool is read-only, mention any rate limits, or describe the default behavior of the 'limit' parameter (though the schema covers this). It falls short of rich 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.
