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.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Host Instruction Projection Skill ## 职责 当任务涉及 always-on instructions 体积、Copilot/Codex/Claude/Gemini/Grok 规则加载、宿主入口文件、生成式规则投影、重复指令碰撞或完整规范回退时，本 Skill 是唯一 Owner。 本 Skill 只负责 `content/instructions.md → projection config → generated host projections → coverage receipt → user-global host targets`。分拆规则与 shared 片段由 control-content 编译器解析；发布包的 `instructions.md` 是编译交付路径。它不替代 `intent`、`cp-gate`、`load-profile`、`spec-governance` 或 `host-contract-verification` 的执行正文，也不把派生文件升级成第二规范真相源。 确定性实现位于 `scripts/lib/host-instruction-projection.js`，生成配置位于 `scripts/host-instruction-projection.json`，派生产物位于 `host-projections/`。 ## 触发条件 | 场景 | 是否触发 | |---|:---:| | 修改 `instructions.md` 中 S/C、路由、CP、Context、治理或闭环语义 | 必须 | | 修改宿主入口文件、安装路径或 deployment descriptor | 必须 | | 新增/调整 Copilot、Claude、Codex、Gemini、Grok、Cursor surface | 必须 | | 调整 always-on 指令预算或 full fallback | 必须 | | 仅修改按需 Skill 正文且不触达投影锚点 | N/A + skipReason | ## HostInstructionProjectionGate 投影链固定为： `instructions.md → mandatory rule parser → semantic replay groups → HostKernelV1 → thin wrappers → HostInstructionCoverageReceiptV1`。 - `instructions.md` 是唯一规范真相源；配置只声明抽取规则、语义锚点、宿主包装与预算。 …

How to install
mdr add devcodex-labs/devcodex/host-instruction-projection@sha256:f7a9adea3d0be9f7The line at the top of this page pins the label git:20261018.4abe344, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
