Claude Code/Codexへlocal repositoryの全pluginをcwd非依存でuser installしたいとき、またはCodexへmerge済みGit refから単独installしたいときに、marketplace登録・install・receipt検証へ使う。.
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
## Pre-choice usable artifact execution
Purpose & Output Contractの最小の実成果物またはremote mutation previewをmain contextで作成する。effect別のparse/open・secret・irreversible・corrupt guardだけを実行し、現物path・digest・開き方またはpreview receiptを提示してからaccept-as-is/light/standard/detailedを記録する。accept-as-isはmutationを実行せずhandoff完了とし、後続sectionを実行しない。
## Post-choice selected improvement execution
以下の既存workflow・goal-seek・評価・修正sectionおよびexternal mutation safety wrapperはlight/standard/detailedが記録されて`semantic_evaluator_started`へ遷移した場合だけ実行する。actual mutationはcanonical preview→hook-confirm→authorize→execute wrapperだけを通し、release/exhaustiveは別の明示eventを必要とする。
<!-- external-mutation-guard-cli:v1 -->
### Canonical external mutation receipt flow (mandatory)
Never execute the external mutation argv directly. Replace every angle-bracket placeholder
with the reviewed value from this run; the central CLI fails closed on missing/invalid values.
Resolve the guard plugin root once, before `preview`. An installed plugin cannot reach a sibling
plugin as `<plugin root>/..`, so never guess that path:
```bash
python3 "${PLUGIN_ROOT:-${CLAUDE_PLUGIN_ROOT}}/scripts/extract-plugin-root.py" skill-governance-adapters
```

How to install
mdr add daishiman/harness-dev/run-codex-plugin-install@sha256:9e6169e1feb1a81eThe line at the top of this page pins the label v0.2.0, 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.
