Each tool has a clearly distinct purpose with no ambiguity. The CRUD operations (create, get, update, delete) target different actions, while the query tools (get_all_events, get_events_by_category, get_events_by_date) provide complementary filtering options. The complete_event tool uniquely handles event completion with stamina management, separate from general updates.

Most tools follow a consistent verb_noun pattern (create_calendar_event, delete_calendar_event, update_calendar_event, get_all_events, get_event_by_id, get_events_by_category, get_events_by_date). The only deviation is complete_event, which uses a different verb style and omits the 'calendar' prefix, but this is minor given its distinct functionality.

With 8 tools, this server is well-scoped for calendar management. It provides full CRUD operations plus specialized queries and a unique completion tool, avoiding both under-coverage (e.g., just 1-2 tools) and bloat (e.g., 25+ tools). Each tool earns its place in the workflow.

The toolset offers complete coverage for calendar event management: create, read (with multiple query options), update, and delete operations. It also includes specialized functionality like event completion with stamina tracking and status management. No obvious gaps exist for the domain, supporting full agent workflows without dead ends.
