# hcris-analyst
A skill for analyzing U.S. nonprofit hospital financials. Powered by the [trove project](https://github.com/cbetz/trove)'s parsed HCRIS Hospital 2552-10 data and IRS 990 Schedule H filings, published as Parquet bundles at troveproject.com.
## When to use this skill
Invoke when the user asks about:
- **A specific hospital's profile** — beds, revenue, charity care, ownership, etc. Identifiers are CCN (HCRIS, 6-char) or EIN (IRS, 9-char) or hospital name.
- **Peer context** — how does X look alongside similar hospitals.
- **Field-glossary lookups** — what does Worksheet S-X line Y column Z mean.
- **Cross-form charity-care differences** — the difference between HCRIS Worksheet S-10 charity care cost and IRS Schedule H Part I line 7a financial assistance at cost.
- **Top-N descriptive queries** — largest by some metric, most uncompensated care, etc., when explicitly requested.
- **Schedule H amendments** — has a particular EIN been amended across IRS release years.
- **NL → DuckDB SQL** — translate ad-hoc questions into queries over the bundles.
## Don't use this skill for
- Questions about hospitals not in the U.S. (HCRIS is CMS / Medicare-specific).
- For-profit and government hospitals that don't file 990s — they're in HCRIS but not in the matched CMS+IRS dataset. The skill can answer HCRIS-only questions about them.
- Patient-level outcomes, quality metrics, or readmission rates — those live in CMS Care Compare / Hospital Compare, not HCRIS. Tell the use
