Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries the full burden. It states the tool 'lists' sessions, implying a read-only operation, but does not disclose details like pagination, default behavior for the limit parameter, or whether the search is case-insensitive. There is no mention of side effects, error conditions, or return format specifics, which is a notable gap given the absence of annotations.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
