openehr-assistant-plugin AGENTS.md

openehr-assistant-plugin AGENTS.md is an instructions file for Claude Code, Codex, OpenCode from Cadasto/openehr-assistant-plugin. It costs 6,357 tokens per session, scanned A, original, MIT.

Project-specific instructions for an openEHR assistant plugin. openEHR is an open standard for storing and exchanging electronic health records.

In plain words
What is it for?
Use them when working with clinical records, archetypes, templates, compositions, or AQL queries. They also guide work involving the plugin's skills, commands, agents, and hooks.
Why use it?
They explain the plugin's clinical data concepts, file formats, and rules for communicating with its companion server, reducing mistakes in a specialised healthcare codebase.

Instructions file for Claude CodeCodexOpenCode

Written for Claude Code and Codex and OpenCode: ${CLAUDE_PLUGIN_ROOT} variable, but also the file is AGENTS.md. Also seen: reads .claude/ paths; mentions CLAUDE.md; mentions subagents.

Installs and runs on its own, but its text points at files inside the plugin that ships it — anything it tells you to read at a ${CLAUDE_PLUGIN_ROOT} path is only there once the plugin is installed.

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

openehr-assistant-plugin AGENTS.md 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 5d 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.

AI Guidelines: openEHR Assistant Plugin

This file provides guidance to AI coding assistants working in this repository.

Project Overview

The openEHR Assistant Plugin is an AI plugin by Cadasto B.V. that provides clinical workflow integration with openEHR systems through skills, commands, agents, and hooks.

Domain Context

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

  • Archetypes — reusable clinical content definitions in ADL (Archetype Definition Language) format
  • Templates — use-case-specific constraint sets combining archetypes, in four serialisations: OET (.oet, hand-authored source) and Archetype Designer .t.json (AOM2 differential source) compile to an OPT (runtime contract), from which a vendor web template (Better/EHRbase JSON) is derived for FLAT/STRUCTURED data entry. .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
  • AQL — Archetype Query Language for querying clinical data repositories
  • CKM — Clinical Knowledge Manager, the international archetype/template registry

Not all openEHR content lives in CKM: a small convention exists of tagging GitHub repositories that publish archetypes/templates with the openehr-content topic (~14 repos — freshEHR, Apperta-CKM projects, regional programmes, individual modellers). It is a genuine secondary discovery channel, thinner but broader than CKM for templates, and un-governed — no editorial review, no dependable lifecycle_state, no integrity guarantee. Skills reference it only as a fallback after CKM, and only in the main session: no MCP tool searches it, so it needs WebSearch/gh.

Companion MCP Server

The openehr-assistant-mcp server provides:

  • 12 MCP tools: CKM search/retrieval, guide access, terminology resolution, type specifications, ADL idiom lookup, curated examples search/retrieval
  • 14 MCP prompts: Guided workflows for common tasks, each taking validated arguments
  • Resources: Archetypes, templates, AQL, terminology, type specs, a guide registry spanning six categories (archetypes/, templates/, aql/, simplified_formats/, specs/, howto/), and the openehr://examples/{kind}/{name} namespace for curated worked examples (AQL, FLAT, STRUCTURED, reference .adl archetypes)

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.
