Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description bears full responsibility for behavioral disclosure. It mentions returning a complete context including timeline, which implies convenience but does not disclose side effects (though likely read-only), the size of the response, or any error conditions. It does not state whether it is read-only, which is pertinent since many sibling tools are reads.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
