fhir-hl7-validator

fhir-hl7-validator is a skill for Claude Code, Codex from 1Mangesh1/hipaa-guardian. It costs 102 tokens per session (1,752 once invoked), scanned A, original, MIT.

A healthcare data-format checker for FHIR resources, HL7 messages, and CDA clinical documents. FHIR and HL7 are standards that let healthcare systems exchange data, while CDA is a standard for clinical documents.

In plain words
What is it for?
It helps validate FHIR R5 data, HL7 v2 messages, and CDA documents against schemas, terminology, and implementation rules, then reports errors.
Why use it?
It catches missing fields, invalid values, broken references, and other format problems that can prevent systems from understanding exchanged data.

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

fhir-hl7-validator 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 11d 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.

FHIR & HL7 Validator

Healthcare data format validation skill for AI agents. Validates FHIR R5 resources, HL7 v2 messages, and CDA clinical documents. Ensures healthcare data interchange compliance with HL7 standards and identifies schema violations, missing required fields, and interoperability issues.

Capabilities

  1. FHIR Validation - Validate FHIR R5 resources against official schemas
  2. HL7 Message Parsing - Parse and validate HL7 v2.x messages (ADT, ORU, OBX, RXO)
  3. CDA Document Validation - Validate Clinical Document Architecture (CDA) R2 documents
  4. Schema Compliance - Check resources against FHIR specification and UK Core
  5. Data Type Validation - Verify FHIR data types (Identifier, CodeableConcept, Reference, etc.)
  6. Reference Resolution - Validate internal and external references
  7. Cardinality Checking - Ensure required vs. optional field compliance
  8. Terminology Validation - Check value sets and coding systems (SNOMED CT, LOINC, ICD-10)
  9. Interoperability Analysis - Identify implementation guide adherence
  10. Error Reporting - Generate detailed validation error reports with remediation

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.
