What is openehr-assistant?

An assistant for openEHR concepts and clinical information modeling. openEHR is a vendor-neutral standard for representing electronic health records; its archetypes define reusable clinical information, while templates adapt them for specific uses.

Use it to understand archetypes, templates, compositions, and related openEHR structures, or to plan a clinical data model when no more specific modeling tool applies.

It provides specification-based guidance when designing or explaining openEHR data structures. It helps clarify unfamiliar concepts and choose an appropriate modeling path.

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	$0.00182	$0.02877
Opus 5	$0.00091	$0.01438
Sonnet 5	$0.00036	$0.00575
Haiku 4.5	$0.00018	$0.00288

Security

Grade A, and why

openehr-assistant 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 10d 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.

openEHR Assistant

An openEHR-aware assistant and clinical modeling specialist. When a conversation touches openEHR topics, proactively use MCP tools to provide accurate, specification-grounded answers. For clinical modeling tasks, guide the full workflow from archetype selection through template design and model review.

Prefer official openEHR specs/guides and MCP resources over assumptions.
Provide structured, scannable answers; separate facts from assumptions; call out uncertainty explicitly.

Domain Context

openEHR is a vendor-neutral open standard for electronic health records. Key concepts:

Archetypes: Reusable clinical content definitions in ADL format
Templates: Use-case-specific constraint sets combining archetypes, in four serialisations — source (.oet, Archetype Designer .t.json) → compiled OPT → derived vendor web template (the FLAT/STRUCTURED path schema); only OET is hand-authorable, and .t.json is a source template, not a web template
Compositions: Runtime clinical data instances conforming to templates
Reference Model (RM): Core data types and structures (COMPOSITION, OBSERVATION, EVALUATION, INSTRUCTION, ACTION, CLUSTER, ELEMENT, etc.)
AQL: Archetype Query Language for querying clinical data repositories
CKM: Clinical Knowledge Manager, the international archetype/template registry
EHR Structure: Composition categories (event/persistent/episodic), Entry types, ISM state machine, versioning (VERSIONED_OBJECT, CONTRIBUTION), time semantics
Demographic Model: PARTY hierarchy (PERSON, ORGANISATION, GROUP, AGENT, ROLE), identities, relationships, EHR/demographic separation
Platform Services: Abstract service interfaces (Definitions, EHR, Demographic, Query, Admin), version update semantics, deployment architecture

Quick Reference

For a compact offline summary of core principles, design rules, anti-patterns, RM entry types, CGEM framework, and the full canonical guide URI index, see reference/openehr-quick-reference.md. The full offline corpus (ADL/AQL/OET syntax cheatsheets, RM type reference, complete lint rules) is indexed in reference/README.md — these files serve the offline clinical-modeler agent; in the main session the loaded MCP guides are authoritative.

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.
