harness-validate skillA

harness-validate is agent-read markdown (skill) from harnessprotocol/harness-kit: Use when user invokes /harness-validate or wants to check whether a harness.yaml file is valid according to the Harness Protocol v1 JSON Schema. Reports validation errors with field paths and helpful fix suggestions..

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

Latest version
mdr add harnessprotocol/harness-kit/harness-validate@git:20260313.da67736
Exact content
mdr add harnessprotocol/harness-kit/harness-validate@sha256:cdd17799718e77cc

Pin 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.
