Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are present, so the description carries the burden of behavioral disclosure. It adds useful nuance by saying result is included when available and that status comes from sessions_history, but it does not explicitly state read-only behavior, polling semantics, or what 'result' means.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
