bmm-authoring SKILL.md skillA
bmm-authoring from openehr/ai-plugins is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add openehr/ai-plugins/bmm-authoring@git:20261009.a9028b9Pins git:20261009.a9028b9 in mdr.lock. Pin the fingerprint instead.

Create or edit an openEHR component's BMM schema, the P_BMM JSON in `computable/BMM/` of a `specifications-XX` repo. This skill should be used when the user asks to write a BMM schema from scratch, add, rename or remove a class, attribute, function, invariant or enumeration in the model, set the schema header or includes, or check or fix a `.bmm.json`. Not for regenerating class tables (use class-generation), spec prose (use content-patterns), archetype/template work…
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# openEHR BMM Schema Authoring (P_BMM JSON)
A component's BMM schema, `computable/BMM/openehr_<component>_<release>.bmm.json`, is the source of
truth for its classes. The class tables and diagrams in its documents are generated from it (see
`class-generation`), and
[`specifications-ITS-BMM`](https://github.com/openEHR/specifications-ITS-BMM) republishes it as JSON,
ODIN and YAML. Change the model here, and only here.
- **Format reference**: `${CLAUDE_SKILL_DIR}/references/p-bmm-json.md`. Before editing, read the
sections for the constructs involved (its Contents lists header, packages, every class, property,
type and function kind, what the tables show, and the spec features the toolchain does not read).
- **Worked example**: `${CLAUDE_SKILL_DIR}/assets/openehr_demo_0.1.0.bmm.json`, one of each common construct.
- **Checker**: `${CLAUDE_SKILL_DIR}/scripts/check_bmm.py` (Python 3.8+, standard library only, read-only).
## Where It Applies
Only in a component repo. Check `manifest.json` `id` (or the directory name `specifications-<id>`)
first. In the ITS-XML, ITS-BMM, ITS-JSON and ITS-REST repos, create and edit no BMM schema. Say that

How to install
mdr add openehr/ai-plugins/bmm-authoring@sha256:b7f595607c933eccThe line at the top of this page pins the label git:20261009.a9028b9, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
