An open-source library of failure modes and evaluation prompts for healthcare AI agents.
Healthcare AI agents fail differently than general AI agents. A hallucinated medication
status, a misrouted prior auth, or a fabricated CPT code can harm a patient or trigger
a compliance violation. healtheval gives you named failure modes and the infrastructure
to catch them.
This is not a validated clinical safety system. It is a framework for healthcare AI engineering teams to build their own clinical evaluators.

HealthEval is an open-source framework for evaluating healthcare AI systems across coding accuracy, clinical reasoning, safety, compliance, and operational performance.

Step 1 — Deterministic check (always runs, free, no API) Rule-based logic catches clear failures: invalid CPT codes, Schedule II drugs as refills, ambiguous routing without uncertainty flags, policy numbers not in the policy document. Fast. No cost. If FAIL found, stops here.
Step 2 — LLM-as-judge (runs if deterministic does not find FAIL) The failure mode eval_prompt is sent to Claude.
- Critical severity → claude-sonnet-4-6
- High / Medium / Low → claude-haiku-4-5-20251001 Requires ANTHROPIC_API_KEY environment variable.
- Deterministic first — rules before LLMs
- Named failure modes — specific, actionable, clinically grounded
- No PHI — all examples synthetic; no real patient data
- Framework-agnostic — any LLM, any agent framework, any observability layer
- Severity is clinical — patient harm potential, not occurrence frequency
- Framework, not validator — engineering tool; not a certified clinical safety system
- Not a certified clinical decision support system
- Not a HIPAA compliance tool
- Not a replacement for clinical validation or human review
- Not a guarantee that your AI agent is safe
