 `@deepseek-ai/dsh-repository-plugin` owns a restricted `.dsh-plugin` package format with two contribution kinds only: skill roots and one common `.mcp.json`. Its package metadata uses `package.json#dsh.skills` for relative skill-root paths and `package.json#dsh.mcpServers` for the relative MCP document path. At least one is required. Each path may leave `.dsh-plugin` to reuse repository content but must remain beneath the directory containing that `.dsh-plugin`; a nested selectable Plugin therefore owns the adjacent subtree above its package without gaining access to unrelated host paths.
 
-The `.dsh-plugin` package declares `dsh-plugin-prepare` as its ordinary package-manager `prepare` script. The helper validates metadata and source types, strictly parses `.mcp.json`, copies static assets into `dsh-plugin-assets`, and writes `dsh-plugin.mjs`. The `.mjs` extension avoids imposing `type: module` on repository-authored package metadata. The generated module is a fixed import-free template containing only a normalized manifest, an `inject` list derived from it (`loader`, plus `skills` and/or `tools` per the declared capabilities, so the wrapper fiber gates on the services its children need), and delegation to the `dsh-repository-plugin` Loader builtin. Preparation never discovers, transpiles, bundles, or preserves a custom repository entry point.
+The `.dsh-plugin` package declares exact `scripts.prepack: "dsh-plugin-prepare"` metadata without depending on a DSH npm package. During Git installation, the standalone runtime temporarily supplies that command from its own build on the isolated lifecycle `PATH`; `prepack` runs after dependency installation and before pnpm packs a selected subdirectory, including a Plugin nested inside another package-manager workspace. The helper validates metadata and source types, strictly parses `.mcp.json`, copies static assets into `dsh-plugin-assets`, and writes `dsh-plugin.mjs`; the source loader revalidates the installed package's exact lifecycle metadata before importing that wrapper.

The host-owned command rationale is in the [Git source preparation repair](../bug-fix/2026-08-08-host-owned-git-repository-plugin-preparation.md).
 
 Loading the DSH package registers that builtin as an effect. A generated wrapper mounts the builtin as its child with `import.meta.url`, so all contributions belong to the wrapper fiber and disappear on Loader removal or rollback. The builtin revalidates the prepared manifest and path containment before reading assets. It composes the existing implementations rather than registering skills or MCP tools itself.

 ## Testing
 
-Focused tests prepare skills and MCP metadata, prove the emitted wrapper contains no imports, reject Work IQ-style OAuth fields, map Expo-style HTTP and DataJunction-style stdio plus environment values, and exercise missing variables. A real Loader test mounts a generated wrapper through the registered builtin, reads its skill through `ctx.skills`, removes the Loader entry, and observes provider cleanup. The keyless headless example loads a checked-in prepared wrapper through its real `cordis.yml` and snapshots the repository skill's logged model catalog row.

 `@deepseek-ai/dsh-repository-plugin` 负责一个受限的 `.dsh-plugin` package 格式，且只允许两类贡献：skill 根和一个通用 `.mcp.json`。Package metadata 使用 `package.json#dsh.skills` 声明相对 skill 根路径，使用 `package.json#dsh.mcpServers` 声明相对 MCP 文档路径；两者至少需要一个。路径可以离开 `.dsh-plugin` 以复用仓库内容，但必须留在包含该 `.dsh-plugin` 的目录之下；因此，一个嵌套且可选择的 Plugin 可以拥有其 package 上方相邻的子树，却不能访问无关宿主路径。
