Set up a project's harness from the installed Codex plugin, using its matching Python engine and generating Codex agents and workflow skills.
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
Resolve the installed plugin root from this skill file: two parent directories above `skills/hm-make/`. Use that absolute path; do not search another runtime's cache. Use the requested project directory. Reuse existing configuration. For a new project, collect any missing meaningful preferences (Side or Production preset, locale); respect preferences already given. The script requires Python 3 and uv on PATH. Run `python3 "<installed-plugin-root>/scripts/codex_setup.py" make "<project>"` with explicit `--preset` and `--locale` when chosen (SPEC strictness derives from the preset; change it later with `/hm:configure`). The bundled bootstrap selects the published engine version matching the plugin release and generates Codex assets through the engine's normal generator. Read the JSON receipt. Report completion only when `state` is `complete`; otherwise identify the pending layers and fixed error code. Do not interpret plugin installation alone as project setup. Preserve existing targets and custom blocks. Start a new Codex thread if newly generated skills are not yet discovered.
Read the whole file at its exact version.
How to install
mdr add ecro/harness-maker/hm-make@sha256:833e60dffbe820acThe line at the top of this page pins the label git:20260921.d330abf, 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.
