hm-update skillA
hm-update is agent-read markdown (skill) from ecro/harness-maker: Update the installed harness-maker Codex plugin, its matching Python engine, and the current project's generated harness while preserving user configuration..
Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns 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@git:20260920.e1a8431mdr add ecro/harness-maker/hm-update@sha256:abfe410dca7f2aa6Pin to a label to follow the author's releases, or to a sha256 to freeze the exact bytes forever. Either way the resolved hash is written to mdr.lock, and mdr install reproduces it on any machine.
