Scored across 21 tools
Each tool maps to a distinct resource and action: activities, events, notes, custom items, wellness, gear, and profile are clearly separated. Within the activity group, list/detail/interval/stream/message endpoints are well differentiated by their descriptions.
Most tools follow a predictable verb_noun pattern like get_activities, create_custom_item, delete_event, and add_activity_message. Minor inconsistencies exist: icu_get_athlete_profile uses an unusual prefix, and add_or_update is used for events/notes while create/update is used for custom items.
21 tools is above the typical 3-15 sweet spot, but the count maps naturally to multiple distinct Intervals.icu domains: activities, events/calendar, custom items, wellness, gear, and athlete profile. It feels slightly heavy rather than bloated or redundant.
The set covers the main workflows well: reading activity data, managing events and notes, full CRUD for custom items, and pulling wellness, gear, and profile information. Minor gaps exist—no activity write/delete operations, no note deletion, and no wellness or gear updates—but these are workable for a mostly read-oriented integration.
