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 | $0.06532 | $0.06532 |
| Opus 5.5 | $0.02613 | $0.02613 |
| Sonnet 5.5 | $0.01306 | $0.01306 |
| Haiku 4.5 | $0.00653 | $0.00653 |
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 26d 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. It supports both Claude Code and Cursor from one tree. It is the workflow layer only; tools, prompts, and resources come from the companion MCP server. Out of scope: building that tooling itself (MCP tools, guides, examples), which is the maintainer openehr-assistant-dev plugin. Human pitch and install: README.md.
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.jsonis 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.
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.

openehr-assistant-plugin AGENTS.md is an instructions file published in the GitHub repository Cadasto/openehr-assistant-plugin (5 stars, last pushed 28d ago), licensed MIT. It adds 6,532 tokens to every session, about $0.0261 per session on Opus 5.5. 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.
