Is the HealthSim skill free?

Yes. The skill itself is free from mark64oswald/healthsim-workspace. SkillProof publishes the install command and an independent test verdict at no cost.

What is the HealthSim SkillProof Score?

9.2/10 — installs cleanly 4/5, triggers reliably 5/5, output vs. baseline 9/10, docs & honesty 5/5.

How do I install HealthSim?

Copy the install command from this page, run it in your terminal, and restart Claude Code. Skills live in ~/.claude/skills/ (global) or .claude/skills/ inside a project.

Can I use HealthSim with Cursor, Copilot, Gemini CLI, Codex or other AI tools?

The SKILL.md format is native to Claude (Claude Code, Desktop, claude.ai). The instructions inside adapt to other assistants: Cursor rules, GitHub Copilot instructions, Windsurf rules, Custom GPTs, AGENTS.md for OpenAI Codex, and GEMINI.md for Google Gemini CLI — our conversion guides cover each, and the free converter on the tools page does the wrapping for you.

Verdict: Tested · Works
Score: 9.2/10
Tested: Jul 16, 2026
Environment: Claude Code 2.x (agent harness)
Upstream re-checked: Jul 16, 2026

⚠ This skill is no longer available upstream. Our re-check on Aug 10, 2026 couldn't find it any more (SKILL.md not found in repo tree). The test below is what we measured on Jul 16, 2026 and we're leaving it up as a record — but there is nothing left to install, so we've removed the command.

Clean, well-scoped medical-data skill with a real synthetic-only disclaimer; the catch is the 'install path' is the whole 23MB/1045-file monorepo (Docker files, deploy scripts, a checked-in DuckDB binary) since the root SKILL.md's relative links reach sibling skills/ formats/ references/ dirs at repo root — a naive cp -r drags all of that in.

Scored on four weighted criteria — install, triggering, output vs. baseline, docs. How scoring works

What HealthSim does

HealthSim is a prompt-driven skill that produces realistic synthetic healthcare data — patients, claims, pharmacy transactions, clinical trial records, and population cohorts — through conversation instead of code. It triggers on requests for synthetic patients/EMR test data, claims/billing/adjudication, pharmacy/PBM data, or output in FHIR R4, HL7v2, X12, NCPDP, or CDISC formats.

How to install HealthSim

Nothing to install: the source repository no longer has this skill. If the author brings it back, our daily re-check will pick it up and the command will reappear here.

Commands — how to trigger HealthSim

/healthsim Generates synthetic patients, claims, and pharmacy data in FHIR/HL7v2/X12/NCPDP for EMR test systems.

It also activates on plain-language prompts like these:

Generate a synthetic diabetic patient with labs and meds for testing
I need a fake X12 837 claim with adjudication for our EMR test suite
Create a synthetic NCPDP pharmacy claim that triggers a DUR rejection
