Scored across 5 tools
list_events, list_today, and list_upcoming all retrieve events and are essentially conveniences over the same underlying range query, so boundaries overlap slightly. However, each has a clearly documented default range/purpose, making selection reasonably predictable.
All names follow a consistent snake_case verb_noun pattern: list_events, list_today, list_upcoming, search_events, get_calendar_info. No mixing of conventions.
Five tools is well-scoped for a read-only ICS calendar feed, with each tool earning its place and no redundancy beyond the intentional convenience listers.
The domain is a read-only ICS feed, so no create/update/delete is expected. Listing (by range, today, upcoming), searching, and calendar metadata cover the realistic surface with no dead ends.
