Update the installed harness-maker Codex plugin, its matching Python engine, and the current project's generated harness while preserving user configuration.
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-update/`. Use the requested project directory and existing configuration. Python 3, uv, and a Codex CLI supporting `plugin marketplace upgrade` and `plugin add` must be available. Run `python3 "<installed-plugin-root>/scripts/codex_setup.py" update "<project>"`. If installed from a differently named marketplace, pass its actual name with `--marketplace`. The script refreshes the registered marketplace, reinstalls `harness-maker@<marketplace>`, reads the returned installed root/version, and runs the new package's helper with its matching published engine to regenerate the project. Inspect `plugin`, `engine`, `project`, and `pending` independently. Only `state: complete` means all three match. On failure, report the fixed error code and completed/pending layers; resolve the cause before retrying. Do not fall back to an unpinned engine or report marketplace refresh alone as completion. Existing projects keep their targets and custom blocks. For a project without a harness, use hm-make first. …

How to install
mdr add ecro/harness-maker/hm-update@sha256:abfe410dca7f2aa6The line at the top of this page pins the label git:20260920.e1a8431, 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.
