harness skillA
harness is agent-read markdown (skill) from stone16/harness-engineering-skills: Plan or execute complex tasks through the harness checkpoint, evaluation, and retro workflow..
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.
How to install
mdr add stone16/harness-engineering-skills/harness@v0.17.0mdr add stone16/harness-engineering-skills/harness@sha256:fa569f7c62b4079aPin 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.
