generating-synthea-data
Generates synthetic but realistic patient records (FHIR R4 bundles, C-CDA documents, CSV) with MITRE Synthea for development, CI fixtures, demos, and leakage-gate test sets — zero real PHI. Use when you need safe, shareable test data for an OpenMed pipeline, reproducible fixtures for tests, or a held-out set for de-identification leakage gates, instead of touching real clinical data. Synthea output feeds the FHIR/C-CDA ingestion skills and openmed.eval. Trigger keywords: Synthea, synthetic data, fake patients, test fixtures, demo data, FHIR bundle generator, synthetic EHR, no PHI.

Same command for any agent — swap --agent for codex, cursor, copilot.
Weekly change comes from our own snapshots, not the repository page — it measures attention, not adoption.
# Generating Synthetic Patient Data with Synthea You cannot develop, test, or demo a clinical NLP pipeline on real PHI without a mountain of governance — and you shouldn't have to. **Synthea** (MITRE's Synthetic Patient Population Simulator) generates statistically realistic, fully synthetic patients: complete longitudinal records as FHIR R4 bundles, C-CDA documents, and flat CSV, with **zero real-PHI risk**. Use it for OpenMed dev fixtures, CI, demos, and — importantly — as **held-out test sets for de-identification leakage gates**, where you need known-synthetic "PHI" to measure recall. ## When to use - Building or demoing an OpenMed ingestion pipeline (FHIR, C-CDA) and need shareable input that is safe to commit and pass around. - Creating deterministic CI fixtures so tests don't depend on protected data. - Producing a leakage-gate test corpus: synthetic notes with *known* fake identifiers, so you can score whether `openmed.deidentify` removed them all. - Teaching/onboarding without a data-use agreement. ## Quick start Synthea is a Java tool. Generate a small population in multiple formats: ```bash # Requires Java 11+. Clone and build once. git clone https://github.com/synthetic

How do I install it?
Run `npx skills add maziyarpanahi/openmed --skill generating-synthea-data --agent claude-code` — it drops the skill into your project so the agent can pick it up. Swap the --agent value for codex, cursor or copilot if you use one of those.
Where does this skill come from?
From maziyarpanahi/openmed, a repository with 4,851 stars. We read it straight from the repository tree rather than a submitted listing, so what you see here is what is actually published.
Is a popular skill a good skill?
Not necessarily. Stars measure attention, not adoption — a repository can trend for a week and be abandoned. That is why we show the weekly change from our own snapshots next to the total, instead of a single flattering number.
