host-contract-verification skillA

host-contract-verification is agent-read markdown (skill) from devcodex-labs/devcodex: 宿主契约验证规范 — 为 Hook / CLI / bootstrap / visible envelope / workspace guard / LinkCapabilityDecision / MCP fallback 定义 direct replay、fixture replay、部署同步与证据路线.

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-contract-verification@git:20260829.ef3a006
Exact content
mdr add devcodex-labs/devcodex/host-contract-verification@sha256:d54d49e1c7c78cb1

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.
