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 timwukp/agent-skills-best-practice/agentcore-harness-builder@git:20260813.e5fc421
Exact content
mdr add timwukp/agent-skills-best-practice/agentcore-harness-builder@sha256:d98e3df0d49e16d1

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.
