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.

For rule 4, verify attribute names against the RM with type_specification_get when uncertain.

Offline fallback only: skills/openehr-assistant/reference/lint-rules-complete.md mirrors these definitions as the clinical-modeler agent's fallback when its read-only MCP lookups are blocked. In the main session, always prefer the loaded archetypes/rules guide.

Avoid known false positives

• ITEM_TREE.items {0..*} is idiomatic — the established CKM convention for container attributes (e.g. the published ecg_result.v1). Do not flag it under rule 9 / structural-constraints when at least one contained ELEMENT is mandatory; reserve a finding for genuinely empty or all-optional containers. Flagging idiomatic items {0..*} is noise.
• Unstated occurrences/existence are not violations — ADL 1.4 defaults both to {1..1} when unstated. For rule 5, also check mutual consistency: the sum of sibling occurrences ranges must fit inside the container's cardinality interval (validator-tooling check VCOC).
• Validity codes are tooling constructs — mnemonics like VARID/VCOC/VUNT come from AOM2 and validator tooling (ADL Workbench, archie, CKM), not from ADL 1.4 spec text. Cite them as tool-output aids, never as "ADL 1.4 validity rules".
• Partial terminology coverage is valid — a term_bindings section need not bind every internal at-code (ADL 1.4, Term_bindings). Do not report unbound codes as a rule 17/18 violation; bindings are optional-but-recommended, so incomplete coverage is at most an INFO observation.

Step 4: Generate Report

Required Output Format

## Lint Report

**Archetype:** <archetype-id>
**Mode:** STRICT | PERMISSIVE
**Overall Status:** PASS | FAIL

### Violations

| # | Severity | Rule | Explanation | Suggested Fix |
|---|----------|------|-------------|---------------|
| 1 | ERROR    | R4   | Attribute `blood_pressure` is not a valid RM attribute on ITEM_TREE | Use `items` (valid RM path) |

### Summary
- ERRORs: N
- WARNINGs: N
- INFOs: N

Gating logic:

• Any ERROR -> overall status = FAIL
• STRICT mode: any WARNING -> overall status = FAIL
• PERMISSIVE mode: WARNINGs allowed if justified

Step 5: After the Report (routing only)

This skill reports; the report's Suggested Fix column is the ceiling of what it provides. When the user asks for a fix plan or for fixes to be applied, route to the archetype-authoring skill — its fix-syntax mode for parse/structure errors, its review-remediate pipeline (minimal-diff plan, path/semantics impact, version-bump justification) for semantic findings.
