🟢search_facilities(q, address, city, state, zip, ...)
Find certified US skilled nursing facilities near an address or in a city. Filter by CMS ownership type (call list_distinct_values field=ownership first), star rating, abuse flag, or Special Focus status. Returns ownership, ratings, nurse hours (HPRD), nurse/RN turnover, weighted inspection score, beds, fines, straight-line distance_miles, and maps deep-links. distance_miles is crow-flies, not drive time — use maps.google_dir / a mapping service for minutes.

}🟢summarize_facilities(metrics, group_by, ownership, state, city, ...)
Aggregate numeric CMS ProviderInfo fields (n, mean, min, max; optional median) across certified SNFs. Prefer this over paging search_facilities for national or grouped stats. Call list_distinct_values for ownership catalogs; call list_file_dates for filedate. Facility-equal means — not bed-weighted. Missing values excluded per metric. Not causal. Not a substitute for get_facility on a named home. Rate limit 60 requests/minute.

}🟢compare_facilities(ids, filedate)
Compare up to 25 certified skilled nursing facilities by CMS CCN or web slug. Returns the same decision fields as search_facilities (ratings, nurse hours, turnover, inspection score, beds, fines, maps) as a table. Prefer this over looping get_facility against the 60 requests/minute limit.
