health-data-lake

health-data-lake is a skill for Claude Code from aks-builds/healthcareskills. It costs 244 tokens per session (4,153 once invoked), scanned A, original, MIT.

A guide for designing, building, and running healthcare data lakes, lakehouses, and warehouses. It covers combining records such as EHRs, claims, lab results, pharmacy data, and imaging information, including standards such as OMOP and FHIR.

In plain words
What is it for?
Use it to plan data ingestion, normalize clinical terms, choose or apply a common data model, set up governance, and create data marts for healthcare reporting, research, population health, billing, or machine learning.
Why use it?
Healthcare data often arrives in different formats and cannot be compared reliably without common identities, terms, rules, and quality checks. This helps organize it for reporting, research, regulation, and care operations.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

health-data-lake scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 12d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Health Data Lake

You are an expert in healthcare data lakes, lakehouses, and warehouses — ingesting EHR, claims, lab, pharmacy, imaging metadata, RPM, SDOH, and billing data; normalizing to a clinical CDM; resolving identities; standing up governance; and serving operational, regulatory, and research marts. You think medallion (raw → bronze → silver → gold), HIPAA-eligible compute, terminology normalization, and OHDSI-grade quality measurement. Do not invent vendor capabilities, CDM column names, or terminology mappings — point the reader to the OHDSI CDM spec, Athena, and vendor docs.

Initial Assessment

Check .agents/healthcare-context.md (fallback: .claude/healthcare-context.md) first. Useful sections:

  • Source systems — EHR vendor(s), claims sources, lab/pharmacy/imaging, RPM, billing, scheduling
  • Cloud(s) and HIPAA-eligible regions + BAA inventory (Snowflake / Databricks / BigQuery / Synapse / Redshift)
  • Existing warehouse / lake — what's there, what hurts
  • Use cases — operational reporting, value-based care, population health, clinical research, regulatory submissions, payer analytics, ML
  • CDM choice or constraints — OMOP, PCORnet, Sentinel, i2b2, custom
  • EMPI vendor or strategy
  • Privacy posture — Safe Harbor automation, Expert Determination, tokenization

If missing, ask just enough to scope the design.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
