Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.01364 | $0.01364 |
| Opus 5 | $0.00682 | $0.00682 |
| Sonnet 5 | $0.00273 | $0.00273 |
| Haiku 4.5 | $0.00136 | $0.00136 |
Grade A, and why
ai-plugins 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 2d 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.
How it starts
The opening of the file, as written. The whole thing — 73 lines — stays where its author put it; the contents beside it link to each section on GitHub.
ai-plugins
AI-assistant plugins for openEHR — official plugin marketplace of the openEHR Foundation.
Repository Purpose
This repo contains AI-assistant plugins that support openEHR work — packaged as a dual Claude Code and Cursor plugin marketplace; the skill content (SKILL.md, an open cross-tool format) is the canonical artifact, and each assistant gets a thin manifest layer (.claude-plugin/, .cursor-plugin/) around the same skills, so further assistants can be added the same way. It is not a specification repository — it provides AI-assisted tooling for authors working in specifications-XX repos.

Current plugins: openehr-specs — 7 skills (spec authoring, review, governance, content patterns, amendment records, ITS-REST, BMM class generation), 3 subagents (spec-reviewer, xref-auditor, identifier-grounding), and 3 commands (amend, regen-classes, publish).
Key Conventions
- Plugin names:
openehr-<domain>(mandatory prefix — flat global namespace); skill names: terse activity nouns with no prefix (auto-namespaced as<plugin>:<skill>). - Component choice follows the nature of the work: skills = knowledge/workflows (model- or user-invoked); commands (
commands/) = user-initiated actions, markeddisable-model-invocation: trueso they don't compete with knowledge-skill triggering; subagents (agents/) = context-heavy, multi-file, or adversarial work that would otherwise pollute the main context. Commands/agents reference their sibling knowledge skill rather than duplicating it. - Skill
descriptionfrontmatter is lean (~50–75 words): one what+scope sentence → a few representative triggers → short "Not for …" anti-triggers routing to the right sibling/plugin. - Keep each
SKILL.mdbody a lean overview (quick-reference + pointers); push bulky detail (tables, templates, format specs) intoreferences/so it loads only on demand. - Versions must stay in sync across both plugin manifests (
.claude-plugin/and.cursor-plugin/), both marketplace entries, and the release tag ({name}--v{version}). - Never invent identifiers, paths, class names, or conventions — ground everything in published openEHR specifications. To verify, read the spec's Markdown twin: take any
specifications.openehr.org/...page.htmlURL and swap.html→.md. - Do not duplicate community tooling (e.g. CKM/clinical modeling is covered by Cadasto's plugins); this repo covers ground the Foundation owns.
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.

ai-plugins AGENTS.md is an instructions file published in the GitHub repository openEHR/ai-plugins (3 stars, last pushed 2mo ago), licensed Apache-2.0. It adds 1,364 tokens to every session, about $0.0068 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.
