The tools are clearly organized around three data types (readiness, resilience, sleep) with two temporal variants (date range vs. today), making them mostly distinct. However, the 'get_today_*' tools could be seen as overlapping with the date-range versions if an agent specifies today's date, though their dedicated purpose reduces confusion.

All tools follow a consistent verb_noun pattern with 'get_' prefix, and the naming is systematic across data types and temporal variants (e.g., get_readiness_data, get_today_readiness_data). There are no deviations in style or convention.

With 6 tools, this is well-scoped for an Oura data server, covering three key metrics with both historical and current-day access. Each tool serves a clear purpose without redundancy, fitting typical expectations for such a domain.

The server covers the core read operations for readiness, resilience, and sleep data with both date-range and today-specific queries, which is appropriate for a fitness/health tracking domain. A minor gap is the lack of write or update tools (e.g., to set goals or log activities), but as a read-only data retrieval surface, it is largely complete.
