Use when the user asks to update the template or the harness (any language: "update the template", "actualiza el arnés", "mettre à jour le template", "template aktualisieren"). Applies ownership rules, resolves conflicts and updates the manifest/state.
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
# Update the harness
Flow to bring a new template version into a configured project. **It never overwrites `owned` files and never deletes files.**
## When
- The user asks to update the template/harness, or a new tag/commit exists.
- Not mid-change: finish or archive first.
- **Trigger phrases may arrive in any language** — match the intent ("actualiza el arnés", "update the template",
"mettre à jour", "aktualisieren"), not the exact wording.
## Steps
1. **Check state**: `.atlas/state.json` (`template_source`) and `.atlas/manifest.json`.
2. **Get the new template** in a temp directory (`git clone` + `checkout <tag|commit>`).
3. **Run the script** from the project root:
`node .atlas/scripts/actualizar-arnes.mjs --template <path>`
- `owned` → skipped · `generated` → regenerated (adapters with resolved placeholders) ·
`managed` → replaced if the hash matches, otherwise `<file>.new`.
- It backs up and **rewrites `manifest.json` and `state.json`** (version, commit, hashes).
4. **Resolve conflicts**: `diff -u <file> <file>.new`, merge by hand and remove the `.new`.
5. **Validate**: `validar-manifiesto`, `validar-contrato`, `validar-perfiles`, `openspec doctor` and
…Read the whole file at its exact version.
How to install
mdr add cedaniel200/atlas-template/update-harness@sha256:fb574e8f0f13a37bThe line at the top of this page pins the label git:20261022.c5514d3, 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.
