host-instruction-projection is agent-read markdown (skill) from devcodex-labs/devcodex: 宿主指令投影 Owner — 从统一 instructions 真相源确定性生成精简 Host Kernel、薄包装、覆盖回执与完整回退.

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 devcodex-labs/devcodex/host-instruction-projection@git:20260816.0ca777d
Exact content
mdr add devcodex-labs/devcodex/host-instruction-projection@sha256:a5a783dd69ab53ee

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.
