What is archetype-lint?

A checker for openEHR archetypes, which are reusable definitions of clinical information in electronic health records. It evaluates them against 24 rules and labels problems as errors, warnings, or information.

Use it to validate or review an archetype, check compliance with openEHR rules, and identify issues that could make it invalid or unsafe.

It finds structural, terminology, and design problems before an archetype is published or reused. The permissive mode allows warnings during early work, while strict mode requires them to be addressed.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00130	$0.01540
Opus 5	$0.00065	$0.00770
Sonnet 5	$0.00026	$0.00308
Haiku 4.5	$0.00013	$0.00154

Security

Grade A, and why

archetype-lint 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 9d 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.

Archetype Lint

An openEHR archetype linting engine. Evaluate archetypes against 24 normative rules. Classify each violation as ERROR, WARNING, or INFO. ERROR means the archetype is invalid or unsafe.

Step 1: Load Guides (MANDATORY)

guide_get("openehr://guides/archetypes/rules")
guide_get("openehr://guides/archetypes/structural-constraints")
guide_get("openehr://guides/archetypes/anti-patterns")
guide_get("openehr://guides/archetypes/terminology")

Step 2: Determine Mode

STRICT: Zero WARNING tolerance. For publication candidates and CKM submissions.
PERMISSIVE (default): WARNINGs allowed with justification. For early modeling iterations.

If the user does not specify a mode, use PERMISSIVE.

Step 3: Apply Lint Rules

The normative rule definitions live in the archetypes/rules guide loaded in Step 1 — that guide is the single source of truth. If this index ever disagrees with the loaded guide, the guide wins. Use the index below for rule numbering and severity; consult the guide for each rule's full definition, rationale, and worked examples before classifying a violation.

#	Rule	Severity	Group
1	Single Concept	ERROR	Core semantic
2	ENTRY Type Semantics	ERROR	Core semantic
3	Root RM Type Match	ERROR	Core semantic
4	Valid RM Attributes Only	ERROR	Core semantic
5	occurrences vs cardinality	ERROR	Core semantic
6	Specialisation Integrity	ERROR	Core semantic
7	Path Stability	ERROR	Core semantic
8	Term Definition Completeness	ERROR	Core semantic
9	Mandatory Data Justification	WARNING	Structural
10	Arbitrary Upper Bounds	WARNING	Structural
11	CLUSTER Semantics	WARNING	Structural
12	Slot Discipline	WARNING	Structural
13	Template Leakage	WARNING	Structural
14	Unconstrained Leaf Nodes	WARNING	ADL & AOM syntax
15	Attribute Multiplicity Compliance	ERROR	ADL & AOM syntax
16	Ontology Integrity	ERROR	ADL & AOM syntax
17	Terminology Neutrality	WARNING	Terminology
18	Semantic Binding Accuracy	WARNING	Terminology
19	Archetypable Demographics	INFO	Demographic
20	Identity vs Role Separation	ERROR	Demographic
21	Patch Version Discipline	ERROR	Versioning
22	Deprecation Handling	WARNING	Versioning
23	Prose ↔ Slot Consistency	WARNING	Documentation (guide rule D9)
24	Translation Accuracy	WARNING	Documentation (guide rule E7)

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.

archetype-lint is a skill published in the GitHub repository Cadasto/openehr-assistant-plugin (4 stars, last pushed 15d ago), licensed MIT. It adds 130 tokens to every session and 1,540 once invoked, about $0.0006 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
