 ## Problem
 
-A repository that already contains reusable skills or an MCP server declaration should be usable by standalone Harness applications without becoming a Harness SDK project or rewriting its existing layout. Popular repositories must be able to add one `.dsh-plugin` directory while keeping their current skills and `.mcp.json` elsewhere in the tree. At the same time, treating an arbitrary repository entry point as a Cordis Plugin would make every repository a new unrestricted runtime extension surface and would bypass the existing skill and MCP lifecycle owners.
+A repository that already contains reusable skills or an MCP server declaration should be usable by standalone Harness applications without becoming a Harness SDK project or rewriting its existing layout. Popular repositories must be able to add one `.dsh-plugin` directory while keeping their current skills and `.mcp.json` elsewhere in the tree. These portable static contributions still need to reuse the existing skill and MCP lifecycle owners when the same trusted package also carries native Cordis code.
 
 The [package-manager-native repository cache](2026-07-30-package-manager-native-repository-cache.md) prepares an exact package source but intentionally knows nothing about DSH formats. This layer therefore needs a package-manager-compatible authoring format, a deterministic prepared artifact, and a Cordis composition that stays transactional under Loader disposal and replacement.
 
 ## Decision
 
-`@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.
+`@deepseek-ai/dsh-repository-plugin` owns the static contribution subformat inside a `.dsh-plugin` package: skill roots and one common `.mcp.json`.

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 package may additionally declare the explicit code entry owned by the [trusted repository package decision](2026-08-08-trusted-repository-package-code.md), and at least one code or static contribution is required.
 
-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 the published `@deepseek-ai/dsh-repository-plugin` package as a development dependency and a non-empty `scripts.prepack` that invokes its `dsh-plugin-prepare` executable. During Git installation, pnpm installs that dependency from the selected package's own manifest; `prepack` runs after dependency installation and before pnpm packs a selected subdirectory, including a Plugin nested inside another package-manager workspace. The package may build its code first. 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 helper-bearing lifecycle metadata before importing that wrapper. A static-only package still receives an import-free wrapper containing its normalized manifest, service-derived `inject` list, and delegation to the `dsh-repository-plugin` Loader builtin. The dependency and workspace-isolation rationale is in the [Git source preparation repair](../bug-fix/2026-08-08-npm-backed-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.
 
 Each prepared skill set mounts `dsh-skill-local` with a unique `repository:<package-name>` provider name, only the copied custom roots, and watching disabled. `dsh-skill-local` therefore gains two general configuration fields: `providerName` and `includeDefaultRoots`. Their defaults preserve its existing single local provider; repository instances set a distinct name and exclude project/user roots so multiple instances neither collide nor duplicate host-local discovery.
 
-Each `.mcp.json` server becomes one existing `dsh-mcp-client` child. The adapter accepts the common root `{ "mcpServers": ... }`; stdio definitions allow only optional `type: "stdio"`, `command`, `args`, and `env`, while HTTP definitions allow only `type: "http"`, `url`, and `headers`. Exact `${NAME}` process-environment references expand at runtime, after cache preparation; missing names fail Plugin load. HTTP maps to the client's Streamable HTTP transport, and stdio uses the prepared package directory as `cwd`. The existing client alone owns connection attempts, failure logging, remote tool synchronization, tool calls, and disconnects. Consequently an MCP connection failure keeps its established successful-plugin/no-tools behavior and is not reclassified as a repository preparation or Loader failure.

Hooks, commands, agents, apps, arbitrary Cordis code, marketplaces, and discovery are also unsupported.

 [Package-manager-native repository cache](2026-07-30-package-manager-native-repository-cache.md) 会准备一个精确 package source，但有意不了解任何 DSH 格式。因此本层需要一种兼容 package manager 的创作格式、确定性的已准备产物，以及在 Loader dispose 和替换期间仍保持事务性的 Cordis 组合。
 
 ## 决策

-`.dsh-plugin` package 把 `dsh-plugin-prepare` 声明为普通 package-manager `prepare` 脚本。Helper 会校验 metadata 与源码类型，严格解析 `.mcp.json`，把静态资源复制到 `dsh-plugin-assets`，并写入 `dsh-plugin.mjs`。`.mjs` 扩展名避免强迫仓库作者在 package metadata 中设置 `type: module`。生成模块来自固定、无 import 的模板，只包含规范化 manifest、由 manifest 派生的 `inject` 列表（`loader`，加上按声明能力加入的 `skills`／`tools`，使包装 fiber 在其子插件所需服务上门控），以及对 `dsh-repository-plugin` Loader builtin 的委托。准备阶段永远不会发现、转译、打包或保留自定义仓库入口。
+`.dsh-plugin` 包将已发布的 `@deepseek-ai/dsh-repository-plugin` 包声明为开发依赖，并声明非空 `scripts.prepack` 来调用其 `dsh-plugin-prepare` 可执行文件。在 Git 安装期间，pnpm 会按所选包自身的 manifest（元数据清单）安装该依赖；`prepack` 会在依赖安装后、pnpm 打包选定子目录前运行，即使插件嵌套在另一个包管理器工作区内也不例外。包可以先构建其代码。该辅助程序会校验元数据与源码类型，严格解析 `.mcp.json`，把静态资源复制到 `dsh-plugin-assets`，并写入 `dsh-plugin.mjs`；源码 loader 会在导入该包装层前重新校验已安装包的生命周期元数据是否包含辅助命令。仅含静态贡献的包仍会获得无 import 包装层，其中包含规范化 manifest、由服务派生的 `inject` 列表，以及对 `dsh-repository-plugin` Loader builtin 的委托。依赖与 workspace 隔离的设计依据见[Git 源准备修复](../bug-fix/2026-08-08-npm-backed-git-repository-plugin-preparation.md)。
 
 加载 DSH package 会以 effect 方式注册该 builtin。生成的包装模块使用 `import.meta.url` 把 builtin 挂载为自己的子级，因此所有贡献都归属于包装 fiber，并在 Loader 移除或回滚时消失。Builtin 会在读取资源前重新校验已准备 manifest 与路径包含关系。它只组合现有实现，而不自行注册 skills 或 MCP 工具。
 
 每份已准备 skill 集合都会挂载 `dsh-skill-local`，使用唯一的 `repository:<package-name>` 提供方名称、仅包含复制后的自定义根，并禁用监视。因此 `dsh-skill-local` 新增两个通用配置字段：`providerName` 和 `includeDefaultRoots`。默认值保持原有单一本地提供方行为；repository 实例设置不同名称并排除项目／用户根，使多个实例既不冲突，也不会重复宿主本地发现。
 
-`.mcp.json` 中的每个 server 都变成一个现有 `dsh-mcp-client` 子级。适配层接受通用根对象 `{ "mcpServers": ... }`；stdio 定义只允许可选的 `type: "stdio"`、`command`、`args` 与 `env`，HTTP 定义只允许 `type: "http"`、`url` 与 `headers`。严格的 `${NAME}` 进程环境变量引用在运行时、cache 准备之后展开；缺失变量会使 Plugin 加载失败。HTTP 映射到 client 的 Streamable HTTP transport，stdio 使用已准备 package 目录作为 `cwd`。只有现有 client 负责连接尝试、失败日志、远端工具同步、工具调用和断开。因此 MCP 连接失败会继续沿用“Plugin 成功但不注册工具”的既有行为，不会被重新分类为 repository 准备或 Loader 失败。

+# Agent Note: Trusted repository packages load Cordis code
+
+Status: implemented
+
+English | [中文](2026-08-08-trusted-repository-package-code.zh.md)
+
+## Problem
+
+The standalone repository format already installs a selected Git package and runs its dependency and lifecycle code with host authority, but it exposed only copied skills and MCP metadata to DSH. Forbidding a Cordis entry did not create a security boundary: package installation remained trusted executable code while the restriction prevented the package from contributing the Plugin behavior that the Harness architecture is designed to compose.
+
+A repository author also needs to keep an ordinary TypeScript npm package shape. Requiring publication to npm, pre-generated JavaScript in Git, or a DSH-owned TypeScript compiler would make a Git source less capable than the same package installed through a developer-owned SDK project. The first model request must observe any MCP tools that this package starts; background-only initial discovery makes a successful installation nondeterministic at the application boundary.
+
+## Decision
+
+A configured repository package is trusted code. Its `.dsh-plugin/package.json` may declare `dsh.entry` as a relative path to a compiled ESM Cordis Plugin inside that package, alongside or instead of `dsh.skills` and `dsh.mcpServers`. At least one contribution is required. The entry may use namespace exports or a default export and retains ordinary Cordis semantics for `name`, `inject`, `Config`, registrations, startup failure, and effect-scoped teardown.
+
+The package owns its npm dependencies and build toolchain. It declares the published `@deepseek-ai/dsh-repository-plugin` package to obtain the `dsh-plugin-prepare` executable. `scripts.prepack` is a non-empty package-authored command that must invoke that dependency-provided helper, but it may first run `tsc`, `tsdown`, or any other build. DSH neither injects the helper, parses the shell program, nor compiles repository source. The helper validates the metadata after the preceding build, requires the configured entry to resolve to a file within `.dsh-plugin`, validates and copies declared static assets, and writes the prepared `dsh-plugin.mjs` wrapper. The installed package must retain a `prepack` declaration containing that helper command; a missing dependency, wrapper, or build output fails before a cache generation becomes usable.
+
+The generated wrapper first mounts the DSH-owned static runtime for skills and MCP definitions, then dynamically imports and unwraps the explicit entry and mounts it as a child. The wrapper statically declares dependencies implied by the prepared manifest; an entry module's additional `inject` is discovered only when mounted and must already be available in the host composition. Both children must reach Cordis `ACTIVE`; an unsatisfied `inject` or startup exception rejects the repository Loader transaction instead of committing an inert generation. Loader removal, failed replacement, and parent disposal unwind the entry, skill providers, MCP clients, and their effects together.
+
+`dsh-mcp-client` resolves its initial connection and tool synchronization promise as part of Plugin application. Its entry is an `async function`, not an ordinary function returning a Promise: Cordis identifies prototype-bearing ordinary functions as constructors and does not treat a constructor's returned Promise as startup work. A valid server's tools therefore exist before its parent repository wrapper activates and before a one-shot application starts its first model request. Its `failOnStartupError` config preserves optional standalone servers by default while letting repository adapters require their declared servers. Repository-translated MCP clients enable that mode, so initial connection, discovery, or tool-registration failure rejects the candidate generation and rollback still closes the transport.
+
+## Trust boundary
+
+Exact refs, source containment, credential-shaped environment scrubbing, prepared manifests, and immutable cache keys protect identity and composition integrity; they do not sandbox executable package input. Repository lifecycle scripts, transitive npm dependencies, the compiled entry, and spawned MCP servers can exercise the authority available to the DSH process and the Cordis services they receive. Users must therefore trust the selected repository and should pin immutable refs and grant Git only the narrow read credential needed for acquisition.
+
+Model-visible behavior remains governed by the owning DSH seam. A repository entry may register tools, prompt sections, policies, commands, agents, or other effects, but anything reaching a model request still needs the corresponding logged DSH representation and lifecycle cleanup. The repository format grants code loading; it does not weaken those service contracts.
+
+## Alternatives considered
+
+**Keep code forbidden while allowing arbitrary package lifecycles.** Rejected because installation already executes trusted repository code, so the restriction added no isolation and forced Plugin authors to publish or maintain a second integration path.
+
+**Have DSH compile repository TypeScript.** Rejected because compiler choice, module layout, generated chunks, native dependencies, and package metadata belong to the npm package. Running the package's declared build preserves the same boundary as other Git dependencies.
+
+**Import `main`, `exports`, or another discovered entry implicitly.** Rejected because an npm package may contain utilities or an MCP executable that is not a Cordis Plugin. The explicit `dsh.entry` field makes code activation reviewable and lets preparation validate the packed path.
+
+**Add a closed manifest field for every future DSH contribution.** Rejected as the universal extension mechanism. Skills and common MCP files retain useful portable static adapters, while DSH-native behavior composes through the existing Cordis Plugin and service contracts.
+
+## Consequences
+
+- A TypeScript DSH Plugin can live in a GitHub repository, install ordinary npm dependencies, compile during `prepack`, and run without publishing the Plugin package to npm.
+- Static-only repository packages remain valid and retain import-free wrappers; adding `dsh.entry` opts that package into runtime code import.
+- A package build, dependency install, entry import, unmet service, or Plugin startup failure prevents the candidate generation from replacing the last good configuration.
+- Initial MCP synchronization can lengthen application startup by the MCP SDK's per-request timeout, and a repository-declared server that is unavailable or cannot publish its complete tool generation prevents that candidate generation from activating.
+- Repository code receives host authority, so source review and immutable pinning are operational security requirements rather than optional hardening.
+
+## Testing
+
+Repository-format tests prepare and mount default-export code entries through the real Loader, observe an entry-owned service, remove the Loader row, and observe cleanup; they also retain skill/MCP preparation, containment, damaged-package, pending-service, and rollback coverage. MCP lifecycle tests require `apply` to settle only after initial tool publication, preserve opt-in contained startup failure, and prove strict connection or tool-registration rejection still closes the client.
+
+The Node 24 consumer acceptance uses the actual built `dsh run` command with a fresh DSH home and an authenticated private GitHub source pinned to the pull request's exact head SHA. The test packs the current repository Plugin build with the same private-field removal and workspace-dependency pinning used for publication, serves its packument and tarball from a job-local npm registry, and directs the Git package's ordinary scoped npm resolution there. That repository package obtains `dsh-plugin-prepare` from the simulated published dependency, installs its other pinned runtime and development dependencies, type-checks and bundles TypeScript during `prepack`, prepares a skill plus a stdio MCP server and `dsh.entry`, exposes the skill and MCP schema in the first real model request, executes the MCP tool, and lets the compiled Cordis entry append a second marker to the result observed in the following request. Registry and cache assertions require npm resolution to reach the simulated publication, source files to be absent from the packed installation, and both built modules, their installed dependency, copied assets, and generated wrapper to be present.

+# Agent Note: 受信任 repository 包加载 Cordis 代码
+
+状态：已实现
+
+[English](2026-08-08-trusted-repository-package-code.md) | 中文
+
+## 问题
+
+独立 repository 格式已经会安装选定的 Git 包，并以宿主权限运行其依赖和生命周期代码，但它向 DSH 暴露的只有复制后的 skill（技能）和 MCP 元数据。禁止 Cordis 入口并未建立安全边界：包安装过程仍会执行受信任代码，而这项限制却阻止包贡献 Harness 架构本就用于组合的插件行为。
+
+仓库作者还需要保持普通 TypeScript NPM 包的结构。如果要求发布到 NPM、把预生成的 JavaScript 签入 Git，或使用 DSH 自有的 TypeScript 编译器，Git 源的能力就会弱于通过开发者自有 SDK 项目安装的同一个包。首个模型请求必须看到该包启动的所有 MCP 工具；仅在后台进行初始发现，会让一次成功安装在应用边界上具有不确定性。
+
+## 决策
+
+已配置的 repository 包是受信任代码。其 `.dsh-plugin/package.json` 可以连同 `dsh.skills` 和 `dsh.mcpServers` 声明 `dsh.entry`，也可以用它取代二者；`dsh.entry` 是指向该包内已编译 ESM Cordis 插件的相对路径。至少需要一种贡献。入口可以使用 namespace 导出或 default export，并沿用 Cordis 对 `name`、`inject`、`Config`、注册、启动失败和 effect 作用域清理的常规语义。
+
+包自行负责其 NPM 依赖和构建工具链。它声明已发布的 `@deepseek-ai/dsh-repository-plugin` 包以取得 `dsh-plugin-prepare` 可执行文件。`scripts.prepack` 是由包作者编写的非空命令，必须调用该依赖提供的辅助程序，但可以先运行 `tsc`、`tsdown` 或其他任意构建。DSH 不会注入辅助程序，也不会解析该 shell 程序或编译 repository 源码。辅助程序会在前序构建之后校验元数据，要求已配置入口解析到 `.dsh-plugin` 内的文件，校验并复制已声明的静态资源，再写入已准备的 `dsh-plugin.mjs` 包装层。已安装包必须保留包含该辅助命令的 `prepack` 声明；依赖、包装层或构建输出缺失会在缓存 generation 可用前导致失败。
+
+生成的包装层先挂载 DSH 自有的静态运行时来处理 skill 和 MCP 定义，再动态导入显式入口、解包其导出并将其挂载为子级。包装层会静态声明已准备 manifest（元数据清单）所隐含的依赖；入口模块的额外 `inject` 只有在挂载时才会被发现，并且此时必须已存在于宿主组合中。两个子级都必须进入 Cordis `ACTIVE`；无法满足的 `inject` 或启动异常会拒绝 repository Loader 事务，而不会提交未激活的 generation。Loader 移除、替换失败和父级 dispose（资源释放）会一并撤销入口、skill 提供方、MCP client 及其 effect。
+
+`dsh-mcp-client` 会在插件应用期间完成其初始连接和工具同步 promise。其入口必须是 `async function`，而不是返回 Promise 的普通函数：Cordis 会把带 prototype 的普通函数识别为 constructor，不会把 constructor 返回的 Promise 当作启动工作。因此，有效 server 的工具会在父级 repository 包装层激活前、一次性应用发起首个模型请求前就已存在。其 `failOnStartupError` 配置默认保留独立可选 server 的行为，同时允许 repository adapter 要求已声明 server 必须可用。Repository 转换出的 MCP client 会启用该模式，因此初始连接、发现或工具注册失败会拒绝候选 generation，回滚仍会关闭 transport。
+
+## 信任边界
+
+精确 ref、源路径包含约束、清除名称符合凭据模式的环境变量、已准备的 manifest 和不可变缓存键，可以保护身份与组合完整性；它们不会为可执行包输入提供沙箱隔离。Repository 生命周期脚本、传递性 NPM 依赖、已编译入口和 spawn 的 MCP server 可以行使 DSH 进程可用的权限，以及它们所获 Cordis 服务授予的权限。因此，用户必须信任所选仓库，应当固定不可变 ref，并只授予 Git 获取源码所需的最小只读凭据。
+
+模型可见行为仍由所属 DSH seam 管理。repository 入口可以注册工具、提示词段落、策略、命令、agent（智能体）或其他 effect，但任何进入模型请求的内容仍须具有对应的 DSH 日志表示和生命周期清理。repository 格式授予代码加载能力；它不会削弱这些服务契约。
+
+## 考虑过的替代方案
+
+**继续禁止代码，但允许任意包生命周期。** 拒绝，因为安装过程本就执行受信任的 repository 代码，所以该限制没有提供隔离，反而迫使插件作者发布或维护第二条集成路径。
+
+**由 DSH 编译 repository TypeScript。** 拒绝，因为编译器选择、模块布局、生成分片、原生依赖和包元数据属于 NPM 包。运行包所声明的构建，可以保持与其他 Git 依赖相同的边界。
+
+**隐式导入 `main`、`exports` 或其他发现的入口。** 拒绝，因为 NPM 包可能包含并非 Cordis 插件的实用工具或 MCP 可执行文件。显式 `dsh.entry` 字段使代码激活可供评审，并让准备阶段校验打包后的路径。
+
+**为未来每种 DSH 贡献添加封闭 manifest 字段。** 不采用它作为通用扩展机制。skill 和通用 MCP 文件仍保留有用的可移植静态适配器；DSH 原生行为则通过现有 Cordis 插件与服务契约组合。
+
+## 后果
+
+- TypeScript DSH 插件可以存放在 GitHub 仓库中，安装普通 NPM 依赖，在 `prepack` 期间完成编译，并在无需把插件包发布到 NPM 的情况下运行。
+- 仅含静态贡献的 repository 包仍然有效，并保留无 import 包装层；添加 `dsh.entry` 会使该包选择启用运行时代码导入。
+- 包构建、依赖安装、入口导入、所需服务未满足或插件启动失败，都会阻止候选 generation 替换最后一个可用配置。
+- 初始 MCP 同步可能因 MCP SDK 的单次请求超时而延长应用启动时间；repository 声明的 server 不可用或无法发布完整工具 generation 时，该候选 generation 无法激活。
+- Repository 代码获得宿主权限，因此源码评审和锁定不可变 ref 是运行安全要求，而不是可选加固措施。
+
+## 测试
+
+repository 格式测试通过真实 Loader 准备并挂载使用 default export 的代码入口，观察入口自有服务，移除 Loader 配置项，再观察清理；测试还保留针对 skill／MCP 准备、路径包含约束、包损坏、等待服务和回滚的覆盖。MCP 生命周期测试要求 `apply` 只在初始工具发布后完成，保留可选择启用的启动失败收束行为，并证明严格连接拒绝或工具注册拒绝仍会关闭 client。
+
+Node 24 消费方验收使用实际构建的 `dsh run` 命令、全新 DSH 主目录，以及锁定到 PR（Pull Request）的精确 head SHA 且经过认证的私有 GitHub 源。测试会采用发布时相同的移除 `private` 字段和固定 workspace 依赖版本流程，对当前 repository 插件构建进行打包；再由作业本地 NPM 注册表提供其 `packument` 与 tarball，并把 Git 包的常规 scoped NPM 解析指向该注册表。该 repository 包从模拟发布的依赖取得 `dsh-plugin-prepare`，安装其他固定版本的运行时依赖与开发依赖，在 `prepack` 期间对 TypeScript 进行类型检查和打包，准备一个 skill、一个 stdio MCP server 及 `dsh.entry`，在首个真实模型请求中暴露 skill 与 MCP schema，执行 MCP 工具，并让已编译 Cordis 入口向结果追加第二个标记，供后续请求观察。注册表与缓存断言要求 NPM 解析必须命中模拟发布，打包安装中不存在源码文件，同时必须存在两个已构建模块、其已安装依赖、复制资源和生成包装层。

+# Agent Note: npm-backed preparation makes GitHub repository Plugins self-contained
+
+Status: implemented
+
+English | [中文](2026-08-08-npm-backed-git-repository-plugin-preparation.zh.md)
+
+## Problem
+
+The repository Plugin authoring contract requires `scripts.prepack` to invoke `dsh-plugin-prepare`. Supplying that executable from the running DSH installation made a source package appear valid even when its own manifest could not obtain the helper. It therefore did not prove the behavior users need after `@deepseek-ai/dsh-repository-plugin` is published: an ordinary Git-hosted npm package must be installable and preparable from only its declared dependencies.
+
+A selectable `.dsh-plugin` inside a pnpm workspace has a second isolation requirement. pnpm prepares a Git-hosted package by running the repository's preferred package manager before packing the selected subdirectory. A nested `pnpm install` can join the containing workspace; when the root lockfile does not list `.dsh-plugin` as an importer, pnpm can report success without installing dependencies declared only by that package. Its TypeScript build or prepare command then fails, or a pre-generated artifact hides the missing dependency.
+
+The checked-in headless fixture mounts an already prepared wrapper. It proves runtime composition, not GitHub acquisition, npm resolution, or package-owned preparation.
+
+## Decision
+
+The `.dsh-plugin` package declares `@deepseek-ai/dsh-repository-plugin` as an ordinary development dependency and invokes its published `dsh-plugin-prepare` executable from `scripts.prepack`. The package may declare any other build and runtime dependencies and run arbitrary compilation before the helper. The repository Plugin package marks its Cordis and DSH peers optional so a helper-only development install resolves only the helper's actual `zod` runtime dependency; an application composition still supplies the peers used by the package's Cordis entry.
+
+DSH does not materialize or prepend a prepare executable. `RepositoryCache` supplies only a transaction-owned `pnpm` wrapper: the outer install runs the pinned pnpm entry directly, while pnpm's hard-coded Git-package `pnpm install` reinvokes the same entry with `--ignore-workspace`. The selected package therefore owns dependency resolution even beneath another pnpm lockfile, and normal package-manager lifecycle `PATH` construction exposes `node_modules/.bin/dsh-plugin-prepare`. The temporary pnpm wrapper disappears after the child settles. The repository remains trusted package-manager input: all dependency and lifecycle code executes under the existing trust contract.
+
+The Node 24 consumer lane passes an exact source derived from the pull request head repository and SHA. It uses the existing private DeepSeek Harness repository rather than creating another repository per run. A job-scoped Git configuration gives the read-only job token access to that exact private source and rewrites pnpm's SSH fallback to authenticated HTTPS.
+
+The built-entry acceptance also creates an in-process npm registry. It stages the current built `@deepseek-ai/dsh-repository-plugin` as a publication artifact by removing `private`, replacing workspace protocols with the release version, and packing the declared files. The registry serves the resulting packument and tarball, while a job-local npm config directs only the `@deepseek-ai` scope to it. The real built `dsh run` child then fetches the exact Git source; that package resolves the helper through npm, type-checks and bundles a TypeScript Cordis entry and MCP server, prepares the adjacent skill, and loads all three contributions. A deliberately failing host `PATH` command proves the lifecycle selected the dependency-local executable. The acceptance also requires registry resolution and inspects the immutable prepared cache, so restoring a host-injected helper cannot satisfy it.
+
+## Alternatives considered
+
+**Inject `dsh-plugin-prepare` from the running DSH installation.** Rejected because it lets an incomplete repository manifest pass and tests a host-only path that npm consumers cannot reproduce.
+
+**Publish the source fixture itself to npm.** Rejected because the product contract is specifically that the DSH Plugin remains Git-hosted; only the reusable preparation helper is an npm dependency.
+
+**Create a new private GitHub repository in every CI run.** Rejected because the pull request repository at its exact head SHA is already a real authenticated private Git remote. Per-run repository mutation would add credentials, cleanup, and eventual-consistency failure modes without changing the acquisition path.
+
+**Prepare after `RepositoryCache` installs the selected package.** Rejected because pnpm's packed subdirectory no longer contains sibling source assets referenced by paths such as `../skills`; preparation must happen before packlist.
+
+**Clone GitHub repositories in DSH and bypass pnpm's Git fetcher.** Rejected because it would duplicate ref resolution, subdirectory selection, dependency installation, packlist behavior, and cache integrity already owned by the pinned package manager.
+
+## Consequences
+
+- A repository author can commit a `.dsh-plugin` package, TypeScript source, skills, and MCP definitions to GitHub without publishing that Plugin package to npm. The package must declare the published preparation dependency.
+- Private GitHub sources use the host's standard Git authentication. CI proves that path with a temporary read-only configuration rather than persistent runner credentials.
+- `prepack`, not `prepare`, is part of the authoring format. It may contain arbitrary package-owned build steps but must invoke the dependency-provided helper; missing dependency or lifecycle metadata fails before a cache generation is usable.
+- A selected package in a pnpm repository installs from its own manifest rather than an enclosing workspace. It cannot rely on workspace-only hoisting; ordinary registry and relative `file:` dependencies remain package-owned inputs.
+- Exact source strings identify immutable cache generations; a changed ref or source configuration selects another generation.
+- Package dependencies, compilation, preparation, and the trusted `dsh.entry` contribution remain owned by the repository package and the [trusted-code decision](../architecture/2026-08-08-trusted-repository-package-code.md).
+
+## Testing
+
+`packages/boot/app-boot/tests/repository-cache.spec.ts` runs a package excluded from its source repository's root pnpm lockfile through a local Git subpath and requires relative `file:` dependencies to provide both its build command and `dsh-plugin-prepare`; it also proves that visible environment survives while credential-shaped variables are scrubbed. `packages/self-modification/repository-plugin/tests/repository-plugin.spec.ts` pins helper-bearing `prepack` metadata and preparation output. `examples/headless-agent/tests/keyless-smoke.e2e.ts` keeps the checked-in prepared fixture on that source contract. `apps/cli/tests/github-repository-plugin.built.e2e.ts` is the product acceptance: simulated published helper package, job-local npm registry, fresh DSH home, exact authenticated private GitHub source, actual built `dsh run`, package-owned TypeScript build, real MCP execution, code-entry transformation, mock LLM request observation, and prepared cache inspection.

+
+状态：已实现
+
+[English](2026-08-08-npm-backed-git-repository-plugin-preparation.md) | 中文
+
+## 问题
+
+repository 插件创作契约要求 `scripts.prepack` 调用 `dsh-plugin-prepare`。如果由正在运行的 DSH 安装提供该可执行文件，即使源包自身的 manifest（元数据清单）无法取得辅助程序，它也会显得有效。因此，这并未证明 `@deepseek-ai/dsh-repository-plugin` 发布后用户所需的行为：普通 Git 托管 NPM 包必须只依靠自身声明的依赖即可安装和准备。
+
+pnpm workspace 内可选择的 `.dsh-plugin` 还有另一项隔离要求。pnpm 会在打包所选子目录前运行仓库首选的包管理器，以准备 Git 托管包。嵌套的 `pnpm install` 可能加入外层 workspace；当根 lockfile 未把 `.dsh-plugin` 列为 importer 时，pnpm 可能报告成功，却未安装仅由该包声明的依赖。随后，其 TypeScript 构建或准备命令会失败；也可能因为存在预生成产物，依赖缺失被掩盖。
+
+签入仓库的 headless fixture（测试前置数据）挂载的是已准备好的包装层。它证明运行时组合，而不证明 GitHub 获取、NPM 解析或包自有准备。
+
+## 决策
+
+`.dsh-plugin` 包将已发布的 `@deepseek-ai/dsh-repository-plugin` 声明为普通开发依赖，并在 `scripts.prepack` 中调用其已发布的 `dsh-plugin-prepare` 可执行文件。该包可以声明其他任意构建依赖与运行时依赖，并在辅助程序前执行任意编译。repository 插件包把 Cordis 与 DSH 对等依赖（peer dependency）标为可选，因此仅为使用辅助程序而进行的开发安装只会解析辅助程序实际依赖的 `zod` 运行时依赖；应用组合仍会提供该包 Cordis 入口所使用的对等依赖。
+
+DSH 不会生成准备阶段可执行文件，也不会将其前置到 `PATH`。`RepositoryCache` 只提供一个由事务持有的 `pnpm` 包装脚本：外层安装直接运行锁定的 pnpm 入口，而 pnpm 为 Git 包硬编码的 `pnpm install` 会以 `--ignore-workspace` 重新调用同一入口。因此，即使位于另一个 pnpm lockfile 之下，所选包仍自行负责依赖解析，正常的包管理器生命周期 `PATH` 构造会暴露 `node_modules/.bin/dsh-plugin-prepare`。临时 pnpm 包装脚本会在子进程结算后消失。repository 仍是受信任的包管理器输入：所有依赖与生命周期代码都按既有信任契约执行。
+
+Node 24 消费方 CI 任务会传入从 PR（Pull Request）head 仓库与 SHA 派生的精确源。它复用现有私有 DeepSeek Harness 仓库，而不会为每次运行新建仓库。作业作用域的 Git 配置允许只读作业 token 访问该精确私有源，并把 pnpm 的 SSH 回退改写为已认证 HTTPS。
+
+构建入口验收还会创建一个进程内 NPM 注册表。它通过移除 `private`、将 workspace protocol 替换为发布版本并打包声明的文件，把当前已构建的 `@deepseek-ai/dsh-repository-plugin` 暂存为发布产物。注册表会提供由此生成的 `packument` 与 tarball，作业本地 NPM 配置则只把 `@deepseek-ai` scope 指向它。实际构建的 `dsh run` 子进程随后获取精确 Git 源；该包通过 NPM 解析辅助程序，对 TypeScript Cordis 入口和 MCP server 进行类型检查与打包，准备相邻的 skill（技能），并加载全部三类贡献。一个刻意设为失败的宿主 `PATH` 命令可以证明，该生命周期选中的是依赖内的可执行文件。验收还要求经过注册表解析并检查不可变的已准备缓存，因此恢复宿主注入的辅助程序也无法通过。
+
+## 考虑过的替代方案
+
+**从正在运行的 DSH 安装注入 `dsh-plugin-prepare`。** 拒绝，因为这会让 manifest 不完整的 repository 包通过，并测试 NPM 消费方无法复现的纯宿主路径。
+
+**把源 fixture 本身发布到 NPM。** 拒绝，因为产品契约明确要求 DSH 插件仍托管在 Git；只有可复用的准备辅助程序是 NPM 依赖。
+
+**在每次 CI 运行中创建新的私有 GitHub 仓库。** 拒绝，因为 PR 仓库的精确 head SHA 已是经过认证的真实私有 Git remote。每次运行的仓库变更会增加凭据、清理和最终一致性失败模式，却不改变获取路径。
+
+**在 `RepositoryCache` 安装所选包后再准备。** 拒绝，因为 pnpm 打包后的子目录不再包含 `../skills` 等路径所引用的同仓库相邻资源；准备必须在生成 packlist 前完成。
+
+**在 DSH 中克隆 GitHub 仓库并绕过 pnpm 的 Git 获取器。** 拒绝，因为这会重复实现已由锁定包管理器负责的 ref 解析、子目录选择、依赖安装、packlist 行为和缓存完整性。
+
+## 后果
+
+- 仓库作者可以把 `.dsh-plugin` 包、TypeScript 源码、skill 与 MCP 定义提交到 GitHub，而无需把该插件包发布到 NPM。该包必须声明已发布的准备依赖。
+- 私有 GitHub 源使用宿主的标准 Git 认证。CI 使用临时的只读配置而非运行器上的持久凭据来验证该路径。
+- 创作格式使用 `prepack` 而不是 `prepare`。其中可以包含任意包自有构建步骤，但必须调用依赖提供的辅助程序；依赖或生命周期元数据缺失时，会在缓存 generation 可用前失败。
+- pnpm 仓库中的所选包按自身 manifest 安装，而不继承外层 workspace。它不能依赖仅由 workspace 提升而可见的包；普通注册表依赖和相对 `file:` 依赖仍是包自有输入。
+- 精确源字符串标识不可变缓存 generation；改变 ref 或源配置会选择另一个 generation。
+- 包依赖、编译、准备和受信任的 `dsh.entry` 贡献仍由 repository 包和[受信任代码决策](../architecture/2026-08-08-trusted-repository-package-code.md)负责。
+
+## 测试
+
+`packages/boot/app-boot/tests/repository-cache.spec.ts` 会通过本地 Git 子路径运行一个未列入源仓库根 pnpm lockfile 的包，并要求相对 `file:` 依赖同时提供构建命令与 `dsh-plugin-prepare`；该测试还证明可见环境变量得以保留，而名称符合凭据模式的变量会被清除。`packages/self-modification/repository-plugin/tests/repository-plugin.spec.ts` 锁定包含辅助命令的 `prepack` 元数据与准备输出。`examples/headless-agent/tests/keyless-smoke.e2e.ts` 使签入仓库的已准备 fixture 继续符合该源格式契约。`apps/cli/tests/github-repository-plugin.built.e2e.ts` 是产品验收测试：模拟发布的辅助程序包、作业本地 NPM 注册表、全新 DSH 主目录、精确且经过认证的私有 GitHub 源、实际构建的 `dsh run`、包自有 TypeScript 构建、真实 MCP 执行、代码入口转换、mock LLM（大语言模型）请求观测，以及已准备缓存检查。

 ## Problem
 
-A standalone `dsh` user has no developer-owned SDK project whose `package.json`, lockfile, and `cordis.yml` can carry an external Plugin dependency. Requiring an install command or another state file would make “use this repository” a multi-step workflow, while loading arbitrary repository code would bypass the restricted [static repository Plugin format](../architecture/2026-07-30-static-repository-plugin-format.md). Long-running TUI and Web processes also need a failed edit to preserve their usable Plugin generation and tell observers why the candidate was rejected.
+A standalone `dsh` user has no developer-owned SDK project whose `package.json`, lockfile, and `cordis.yml` can carry an external Plugin dependency. Requiring an install command or another state file would make “use this repository” a multi-step workflow, while trusted repository code still needs an exact-source, transactional lifecycle owned by the [repository package format](../architecture/2026-08-08-trusted-repository-package-code.md). Long-running TUI and Web processes also need a failed edit to preserve their usable Plugin generation and tell observers why the candidate was rejected.
 
 ## Decision
 
 The shipped TUI and Web/headless `cordis.yml` trees contain an empty `repository-plugins` entry. A user changes only `$DSH_HOME/config.yaml`, replacing that entry's config with a `repositories` list. Each item uses `github:owner/repository#<ref>` plus an optional `&path:/.../.dsh-plugin`; omission selects `/.dsh-plugin`. An explicit ref is mandatory, paths are absolute within the repository and end in `.dsh-plugin`, and duplicate normalized specifiers reject before installation. There is no marketplace, discovery index, HTTPS URL vocabulary, or implicit latest generation.
 
-`@deepseek-ai/dsh-repository-plugin` validates and normalizes each source, then resolves it through the generic vendored [`RepositoryCache`](../architecture/2026-07-30-package-manager-native-repository-cache.md). The default cache is `$DSH_HOME/cache/repository-plugins`; `cacheDir` is the explicit deployment override. Bundled pnpm selects the configured repository subpackage, runs its ordinary lifecycle including `prepare`, and atomically publishes the exact specifier. The DSH host imports only the generated `dsh-plugin.mjs` wrapper and mounts it as a child fiber, so skills and MCP retain the owners, failure contracts, and teardown defined by the format package.

Bundled pnpm selects the configured repository subpackage, installs its dependencies, runs its package-authored `prepack`, and atomically publishes the exact specifier. The selected package's direct development dependency on `@deepseek-ai/dsh-repository-plugin` supplies `dsh-plugin-prepare` through package-local `node_modules/.bin`; the lifecycle invokes it after any package-owned build. The DSH host imports the generated `dsh-plugin.mjs` wrapper and mounts it as a child fiber; that wrapper composes static skill and MCP owners plus an explicit trusted Cordis entry when declared.
 
 ## Live update and failure
 
 `dsh-app-boot` mounts the root Include through one helper that retains its exact Loader `Entry`. The TUI and Web register `$DSH_HOME/config.yaml` through Cordis HMR; headless reads the same file at startup without retaining a watcher. A watcher update rebuilds the Include patch list as immutable app-owned patches followed by the newly parsed personal patches, so Web-generated port, session-root, trust, and frontend values survive every personal edit unless a later personal patch deliberately replaces that row.
 
-Cordis serializes and coalesces exact-path changes. Include and Loader reconcile a candidate transactionally: success commits the new source list, while fetch, preparation, wrapper import, format, or child-Plugin failure rejects the candidate and retains or restores the last good tree. HMR normalizes the caught value to `Error`, logs it, and broadcasts the parallel `hmr/config-update-failed(filename, error)` event; observer failures cannot break refresh processing. MCP transport connection failure remains the existing MCP client's contained successful-Plugin/no-tools result and therefore is not reclassified as a config-update failure.

HMR normalizes the caught value to `Error`, logs it, and broadcasts the parallel `hmr/config-update-failed(filename, error)` event; observer failures cannot break refresh processing. Repository MCP servers use strict startup, so an initial connection, discovery, or tool-registration failure rejects the candidate and becomes a config-update failure; non-strict standalone MCP clients retain their contained successful-Plugin/no-tools behavior.
 
 An identical specifier permanently reuses its cache generation. HMR watches configuration, not cached repository code; the user changes the ref, path, or source list to select another generation.
 
 ## Trust boundary
 
-Configuring a repository authorizes package-manager lifecycle code from that repository and its dependencies to run with the user's filesystem authority. The pnpm child removes ambient environment variables whose names contain `KEY`, `PASSWORD`, `SECRET`, or `TOKEN`, but this is credential-exposure reduction rather than a sandbox. The fixed runtime wrapper prevents repository-authored Cordis entry points from becoming part of the supported Plugin format; it does not make package preparation untrusted-safe.

 - First use may require Git/network access and preparation time. Later starts reuse the exact prepared cache; old generations consume disk until a separate cache-management policy exists.
-- Only skills and common MCP definitions are supported. Hooks, commands, agents, apps, arbitrary Cordis code, compatibility shims, OAuth-bearing MCP definitions, and marketplaces remain intentionally absent.
+- Skills and common MCP definitions retain portable static adapters, while an explicit `dsh.entry` can contribute DSH-native Cordis behavior. Format-specific compatibility shims, OAuth-bearing MCP definitions, and marketplaces remain intentionally absent.

 ## 问题
 
-独立 `dsh` 用户没有开发者自有的 SDK 项目，无法由其 `package.json`、lockfile 和 `cordis.yml` 承载外部插件依赖。若要求运行安装命令或维护另一份状态文件，「使用这个仓库」就会变成多步骤流程；若加载任意仓库代码，又会绕过受限的[静态仓库插件格式](../architecture/2026-07-30-static-repository-plugin-format.md)。长时间运行的 TUI 和 Web 进程还必须在编辑失败时保留仍可使用的插件版本，并向观察者说明候选配置被拒绝的原因。
+独立 `dsh` 用户没有开发者自有的 SDK 项目，无法由其 `package.json`、lockfile 和 `cordis.yml` 承载外部插件依赖。若要求运行安装命令或维护另一份状态文件，「使用这个仓库」就会变成多步骤流程；受信任的 repository 代码仍需要由[repository 包格式](../architecture/2026-08-08-trusted-repository-package-code.md)负责一套锁定精确来源且具事务性的生命周期。长时间运行的 TUI 和 Web 进程还必须在编辑失败时保留仍可使用的插件版本，并向观察者说明候选配置被拒绝的原因。
 
 ## 决策
 
 已交付的 TUI 和 Web／无头 `cordis.yml` 配置树包含一个空的 `repository-plugins` 配置项。用户只需修改 `$DSH_HOME/config.yaml`，用 `repositories` 列表替换该配置项的配置。每一项采用 `github:owner/repository#<ref>`，并可追加 `&path:/.../.dsh-plugin`；省略时选择 `/.dsh-plugin`。必须显式指定 ref；路径是仓库内的绝对路径，并以 `.dsh-plugin` 结尾；重复的规范化说明符在安装前即被拒绝。不提供插件市场、发现索引、HTTPS URL 词汇或隐式的最新版本。
 
-`@deepseek-ai/dsh-repository-plugin` 校验并规范化每个源，再通过 vendor 中的通用 [`RepositoryCache`](../architecture/2026-07-30-package-manager-native-repository-cache.md) 解析。默认缓存位于 `$DSH_HOME/cache/repository-plugins`；`cacheDir` 是显式的部署覆盖项。随应用提供的 pnpm 选择配置的仓库子包（package），运行包括 `prepare` 在内的普通生命周期，并原子发布该精确说明符。DSH 宿主只导入生成的 `dsh-plugin.mjs` 包装模块并将其挂载为子 fiber，因此 skill（技能）与 MCP 仍沿用格式包定义的所有者、失败约定和清理行为。

 ## 实时更新与失败
 
 `dsh-app-boot` 通过一个辅助函数挂载根 Include，并保留其确切的 Loader `Entry`。TUI 和 Web 通过 Cordis HMR（热模块替换）注册 `$DSH_HOME/config.yaml`；无头界面在启动时读取同一文件，但不保留监视器。监视器更新会重新构建 Include 补丁列表，先放置不可变的应用自有补丁，再放置新解析的个人补丁。因此，Web 生成的端口、会话根目录、信任和前端值会在每次个人编辑后保留，除非后续个人补丁有意替换相应配置项。
 
-Cordis 会串行处理并合并该确切路径上的变更。Include 与 Loader 以事务方式协调候选配置：成功时提交新源列表；拉取、准备、包装模块导入、格式或子插件失败时拒绝候选配置，并保留或恢复最后一个可用树。HMR 会把捕获的值规范化为 `Error`，记录错误，并广播并行的 `hmr/config-update-failed(filename, error)` 事件；观察者失败不会中断刷新处理。MCP 传输连接失败仍沿用现有 MCP 客户端所收束的「插件成功加载但无工具」结果，因此不会被重新分类为配置更新失败。

 相同说明符会永久复用同一个缓存版本。HMR 监视配置，而非已缓存的仓库代码；用户必须改变 ref、路径或源列表，才能选择另一个版本。
 
 ## 信任边界
 
-配置仓库即授权该仓库及其依赖中的包管理器生命周期代码以用户的文件系统权限运行。pnpm 子进程会移除名称中含有 `KEY`、`PASSWORD`、`SECRET` 或 `TOKEN` 的环境变量，但这只会减少凭据暴露，并非沙箱。固定的运行时包装模块会阻止仓库作者提供的 Cordis 入口成为受支持插件格式的一部分；它无法让包准备过程安全执行不受信任的代码。

+- On connect: plugin activation awaits `listTools()` and registers each tool via `ctx.tools.register()` under its public name before the composition starts its first turn. Initial connection, discovery, or registration failure is always logged; it rejects activation when `failOnStartupError` is true and otherwise activates with no tools.

 - Tool execute: `client.callTool({ name: rawName, arguments }, { signal })` with timeout + abort support—the public name is never sent to the server.
 - Canonical success is `{ content: JsonValue[], structuredContent? }`; complete JSON MCP blocks survive for programmatic callers. A supported advertised `outputSchema` validates `structuredContent`; unsupported schema vocabulary falls back to unconstrained `JsonValue`.

 ## Known Limitations and Deferred Work
 
-- **Initial discovery is asynchronous** — plugin load does not wait for connection and `listTools()`, so a turn started immediately after boot or HMR can assemble before the MCP tools are registered.
 - **Tools are the only bridged MCP capability** — Resources and Prompts have no harness consumption surface and are deferred.
+- **Startup timeout is inherited from the MCP SDK** — DSH does not yet expose a connection/discovery timeout. Each initialize or paginated `tools/list` request uses the SDK's 60-second default, so an unresponsive server or cursor chain can delay both activation and teardown while the initial synchronization settles.
 - **Crash recovery is manual** — transport closure does not auto-reconnect; registered tools can remain visible but fail against the closed transport until an HMR reload or Host restart.
 - **Native non-text rendering is lossy** — image, audio, and resource payloads become placeholders in model context even though the execution-local canonical value preserves their JSON blocks. Richer Native multimedia projection is deferred.
 - **Unsupported MCP output schemas are not enforced** — `structuredContent` falls back to `JsonValue` when the advertised schema uses vocabulary outside the harness subset.

 ## 已知限制与暂缓事项
 
-- **初始发现是异步的**：插件加载不会等待连接和 `listTools()`，因此在启动或 HMR 后立即开始的轮次可能在 MCP 工具注册前完成组装。
 - **只桥接 MCP 的工具能力**：资源和提示词没有 harness 消费接口，暂缓实现。
+- **启动超时继承自 MCP SDK**：DSH 尚未公开连接／发现超时。每次 initialize 请求或分页 `tools/list` 请求都使用 SDK 默认的 60 秒，因此在初始同步完成期间，无响应的 server 或 cursor chain 可能同时延迟激活与 teardown。
 - **崩溃恢复需要手动触发**：传输关闭后不会自动重新连接；已注册工具可能仍然可见，但会因传输已关闭而调用失败，直到 HMR 重载或重启 Host。
 - **Native 非文本渲染有损**：图片、音频与资源载荷在模型上下文中会变成占位符，即使执行局部的规范值保留了其 JSON 块。更丰富的 Native 多媒体投影暂缓实现。
 - **不强制执行不受支持的 MCP 输出 schema**：已声明 schema 使用 harness 子集之外的词汇时，`structuredContent` 会回退到 `JsonValue`。

-Restricted repository Plugin format for DeepSeek Harness. A repository author declares static skill roots and an optional common `.mcp.json` in `.dsh-plugin/package.json`; the prepare helper copies those assets and emits a fixed import-free Cordis wrapper. The runtime wrapper can only delegate to this DSH-owned package, which composes [`dsh-skill-local`](../../skill/skill-local/README.md) and [`dsh-mcp-client`](../../mcp/mcp-client/README.md). Design rationale: [static repository Plugin format Agent Note](../../../.agents/notes/implemented/architecture/2026-07-30-static-repository-plugin-format.md).
+Trusted repository package format for DeepSeek Harness. A `.dsh-plugin` npm package may contribute a compiled Cordis/DSH Plugin entry, skill roots, and a common `.mcp.json`; its ordinary `prepack` lifecycle owns dependency installation and source compilation before the DSH prepare helper validates the outputs and emits the Loader wrapper. Static contributions compose [`dsh-skill-local`](../../skill/skill-local/README.md) and [`dsh-mcp-client`](../../mcp/mcp-client/README.md). Design rationale: [trusted repository package code](../../../.agents/notes/implemented/architecture/2026-08-08-trusted-repository-package-code.md) and the [static contribution subformat](../../../.agents/notes/implemented/architecture/2026-07-30-static-repository-plugin-format.md).

-`dsh.skills` is an optional array of local skill roots. `dsh.mcpServers` is an optional path to one `.mcp.json`; at least one field is required. Paths are relative to `.dsh-plugin`, must stay under its parent source directory, and may therefore refer to existing repository assets such as `../skills`. A repository containing several Plugins gives each one its own `.dsh-plugin` package under a different selectable subdirectory.
+`scripts.prepack` must be non-empty and invoke `dsh-plugin-prepare`; it may run arbitrary package-owned build steps first. The package declares `@deepseek-ai/dsh-repository-plugin` as an ordinary development dependency so its published executable is available to that lifecycle. DSH does not inject the helper: the repository package declares and runs its own compiler, runtime dependencies, preparation helper, and other npm lifecycle code. The selected package is installed from its own manifest instead of inheriting an enclosing pnpm workspace, so declare every dependency it needs and do not depend on workspace-only hoisting. DSH does not transpile TypeScript or infer a package entry.
+
+`dsh.entry` is an optional relative path to a compiled ESM Cordis Plugin inside `.dsh-plugin`. The module may use either namespace exports or a default export and owns its ordinary `name`, `inject`, `Config`, registrations, and effects. `dsh.skills` is an optional array of local skill roots, and `dsh.mcpServers` is an optional path to one `.mcp.json`; at least one of the three fields is required. Skill and MCP paths may reach adjacent repository assets but must remain beneath the directory containing `.dsh-plugin`; the compiled entry must remain inside the package selected and packed by the package manager. A repository containing several Plugins gives each one its own `.dsh-plugin` package under a different selectable subdirectory.
+
+The repository package and every dependency or lifecycle script it runs are trusted code, just like an npm package selected directly by the user. This format is not a sandbox: install only repositories whose code may access the host process, filesystem, network, and services declared through Cordis. Exact refs and the immutable cache provide identity and reproducibility, not isolation.

 Each source must use `github:owner/repository#<ref>`. Omitting `&path:` selects `/.dsh-plugin`; an explicit path is absolute within the repository and must end in `.dsh-plugin`.

+Git transport uses the host's ordinary Git authentication. Public repositories need no credentials; private sources require a read-only credential or SSH agent that can read the selected repository. DSH removes credential-shaped environment variables before package lifecycles, so configure Git itself, such as through a credential helper or job-scoped Git config, instead of expecting an exported token variable to cross that boundary. Repository lifecycle code is trusted and can invoke Git, so use the narrowest repository-scoped credential available.

 Long-lived surfaces watch both `cordis.patch.yml` layers through Cordis HMR. A valid source-list change installs and swaps the complete repository Plugin generation; a failed fetch, prepare, import, or Plugin application keeps the last good tree and broadcasts `hmr/config-update-failed(filename, error)`. One-shot runs read the layers only at startup, and a `--patch` overlay is never watched. An identical source string permanently reuses its prepared cache entry, so selecting changed code requires a ref, path, or other source-config change. App integration rationale: [config-only repository Plugins Agent Note](../../../.agents/notes/implemented/feature/2026-07-30-config-only-repository-plugins.md).
 
 ## Preparation
 
-`dsh-plugin-prepare` validates `package.json#dsh`, verifies skill-root types, parses the MCP file, copies assets under `dsh-plugin-assets`, and writes `dsh-plugin.mjs`. The wrapper contains only the normalized static manifest and fixed code that looks up the `dsh-repository-plugin` Loader builtin. It neither discovers nor compiles repository JavaScript, and the runtime never imports another repository entry point.
-
-The containing package manager still runs the configured repository package's lifecycle scripts. This restriction defines the supported DSH contribution surface; it is not a security boundary for a repository that the user chose to install as executable package-manager source.
+During exact Git installation, DSH's bundled pnpm installs the selected package from its own manifest. A transaction-owned `pnpm` wrapper reinvokes the same pinned pnpm with `--ignore-workspace`, so an enclosing workspace lockfile cannot suppress dependencies declared only by the selected `.dsh-plugin` package. The required `prepack` lifecycle runs after that dependency installation and before the selected subdirectory is packed; its ordinary `node_modules/.bin` lookup obtains `dsh-plugin-prepare` from the declared direct development dependency on `@deepseek-ai/dsh-repository-plugin`. That package marks its Cordis/DSH runtime peers optional so using the executable alone does not install the runtime graph. Package-owned commands may build TypeScript or other source before invoking the helper. The helper validates `package.json#dsh`, verifies that the compiled entry is an in-package file, validates skill and MCP sources, copies static assets under `dsh-plugin-assets`, and writes `dsh-plugin.mjs`. Before importing that wrapper, DSH revalidates that the installed package retained both the direct development dependency and a `prepack` declaration containing the helper command. Failure to resolve the published helper, install dependencies, build, or prepare fails before a cache generation is published. Rationale: [npm-backed Git source preparation Agent Note](../../../.agents/notes/implemented/bug-fix/2026-08-08-npm-backed-git-repository-plugin-preparation.md).
 
 ## Runtime composition
 
-Loading this package registers one effect-scoped Loader builtin. Each generated wrapper delegates to that builtin with its own module URL and prepared manifest. The runtime validates every declared skill root as an existing in-package directory before mounting — a package whose generated outputs were dropped (a `files`/`.npmignore` mistake, a damaged cache entry) fails the plugin load instead of silently mounting a skill-less plugin. Repository skill roots mount as a uniquely named `dsh-skill-local` provider with default project/user roots excluded and watching disabled; cached package generations are immutable. Wrapper disposal removes the provider and all composed MCP clients through normal Cordis child-fiber teardown.
+Loading this package registers one effect-scoped Loader builtin. Each generated wrapper delegates its prepared static manifest to that builtin, then imports and mounts `dsh.entry` when declared. The wrapper can statically gate only the `loader`, `skills`, and `tools` services implied by the prepared manifest; the entry's own `inject` is discovered when that child is mounted. The entry must reach `ACTIVE`, so a missing entry-only service or startup failure rejects the repository generation instead of committing an inert child, and all effects disappear on Loader removal or rollback. The runtime likewise validates every declared skill root as an existing in-package directory before mounting — a package whose generated outputs were dropped by `files`/`.npmignore` or damaged in cache fails instead of silently losing contributions. Repository skill roots mount as uniquely named `dsh-skill-local` providers with default project/user roots excluded and watching disabled; cached package generations are immutable.
 
 ## Common MCP format
 
 The `.mcp.json` root is `{ "mcpServers": { ... } }`. A stdio entry accepts only `type: "stdio"` (optional), `command`, `args`, and `env`; an HTTP entry accepts only `type: "http"`, `url`, and `headers`. String values support exact `${NAME}` process-environment expansion at Plugin load, and a missing name fails that load. HTTP URLs become the existing MCP client's `streamable-http` transport; stdio entries use the prepared package directory as `cwd`.
 
-Unknown fields reject, including OAuth and `auth` objects. There is no `CLAUDE_PLUGIN_ROOT` expansion or compatibility layer. After translation, the existing `dsh-mcp-client` exclusively owns transport creation, connection diagnostics, tool synchronization, calls, and disconnect lifecycle; a network or child-process connection failure retains that client's established log-and-no-tools behavior.
+Unknown fields reject, including OAuth and `auth` objects. There is no `CLAUDE_PLUGIN_ROOT` expansion or compatibility layer. After translation, the existing `dsh-mcp-client` exclusively owns transport creation, connection diagnostics, tool synchronization, calls, and disconnect lifecycle. Repository-declared servers enable its strict startup mode: Plugin activation waits for the initial connection and tool synchronization, so the first model request observes a fully registered initial tool generation, while a network, child-process, discovery, or registration failure rejects the candidate repository generation instead of silently activating without its declared tools.

 ## Known Limitations and Deferred Work
 
-- **Skills and MCP only** — commands, hooks, agents, apps, arbitrary Cordis code, marketplaces, and compatibility shims are intentionally outside this format.
+- **No code sandbox** — `dsh.entry`, npm dependencies, and package lifecycle scripts execute with the DSH host's authority; repository trust is mandatory.
+- **Entry-only service dependencies are not pre-gated** — the generated wrapper cannot declare an entry module's `inject` before importing it. Any service beyond those implied by Skills or MCP must already exist when the wrapper mounts the entry, or that repository generation rejects.
 - **No MCP authentication protocol** — static headers may use environment expansion, but OAuth-bearing definitions reject and private-server login flows are not implemented here.
 - **Generated assets are immutable runtime input** — repository cache generations are not watched; source, ref, path, or configuration must select another prepared generation.

@@ -39,7 +39,7 @@ Keep this log exhaustive — every divergence from upstream must be listed.
 7. **`cordis/src/*.ts` JSDoc enrichment**: added `@param`/`@returns` tags and contract documentation (disposal semantics, waterfall veto, bail conditions, error cases) across the public plugin-author surface — `Context` (class, statics, and the `Context` interface properties incl. `root`), `EventsService`, `Fiber`, `RegistryService`, `ReflectService`, `Service`, `LoggerService` and their `declare module './context.ts'` overloads. Comment-only; no code changes. Motivation: the website API-reference generator renders these docs and hard-errors on undocumented members. Retire this entry when the enrichment is upstreamed to the fork.
 8. **Transactional Loader/Include config reconciliation**: Loader imports a changed entry name before disposal, awaits lifecycle settlement, and restores the previous plugin or config when candidate application fails. Loader settlement rechecks service-gated fibers after current tasks drain, rejects failures, and leaves fibers with absent dependencies pending. Group updates start candidates concurrently, await every outcome, undo changes and additions on failure, await removal, preserve programmatic option identity, and persist direct or tree-level mutations only after success. Include reads and validates detached candidate content, applies patches to a clone, reconciles the tree, and only then commits its cached content/data; direct refresh failures propagate for the caller to contain. A non-array parse is invalid, patches re-apply on every file or Include-config update, an omitted patch list clears the overlay, and initial content falls back to `initial` only on `ENOENT`. Covered by `packages/boot/app-boot/tests/config-reload.spec.ts` and `packages/host/webserver/tests/webserver.spec.ts`.
 9. **`hmr/src/index.ts` exact config watching**: `registerConfig()` watches one absolute config path outside module roots, including a path under missing parents, serializes and coalesces refreshes, and returns an async disposer that closes the watcher and drains active work. Refresh failures are normalized to `Error`, logged, and broadcast through the parallel `hmr/config-update-failed` event; observer failures are contained. Config-file changes discovered by the ordinary HMR watcher use the same serialized path. Covered by `packages/boot/app-boot/tests/hmr-config.spec.ts`.
-10. **`loader/src/repository.ts`, `loader/tsdown.config.ts`, and the `@cordisjs/plugin-loader/repository` export**: the Node-only `RepositoryCache` installs one exact dependency specifier through the bundled `pnpm@11.7.0`, single-flights callers, and atomically publishes only a prepared package plus marker under the specifier hash. The subpath stays out of the browser-reachable Loader entry. Identical specifiers permanently reuse that entry; callers change the ref/specifier for another generation. The isolated workspace permits dependency build scripts because a configured repository is executable code, while the child drops ambient credential-shaped variables. Covered by `packages/boot/app-boot/tests/repository-cache.spec.ts`, including a keyless local-Git prepare run through the bundled pnpm.
+10. **`loader/src/repository.ts`, `loader/tsdown.config.ts`, and the `@cordisjs/plugin-loader/repository` export**: the Node-only `RepositoryCache` installs one exact dependency specifier through the bundled `pnpm@11.7.0`, single-flights callers, and atomically publishes only a prepared package plus marker under the specifier hash. The subpath stays out of the browser-reachable Loader entry. Identical specifiers permanently reuse that entry; callers change the ref/specifier for another generation. A transaction-owned `pnpm` wrapper makes pnpm's nested Git-package install reinvoke the same bundled entry with `--ignore-workspace`, so the selected package installs its own manifest dependencies instead of joining an enclosing source workspace. The temporary command directory is removed after the child settles. The isolated workspace permits dependency build scripts because a configured repository is executable code, while the child drops ambient credential-shaped variables. Covered by `packages/boot/app-boot/tests/repository-cache.spec.ts`, including a keyless local-Git `prepack` whose package is excluded from an enclosing pnpm lockfile and obtains both its build and prepare commands from declared dependencies.
 11. **Vendored Node-compatible TypeScript**: marked erased imports explicitly across `cordis`, `loader`, `include`, `hmr`, and `schemastery` so Node's native TypeScript transform does not request types as runtime exports. Schemastery's source uses an ESM default export and its package declares `type: module`; its built ESM/CJS entries retain explicit `.mjs`/`.cjs` extensions.
 12. **`include/src/index.ts` patch-semantics export**: extracted the private `applyPatches` body into the exported pure function `applyEntryPatches(data, patches, warn)` (the method delegates to it) and exported the `!!js` YAML dialect as `entryListSchema`, so `dsh --dump-config` composes and prints exactly what the include would mount without booting a tree. Behavior-preserving for mounting; the extraction exists because config tooling must never reimplement (and drift from) the patch algorithm. `applyEntryPatches` also indexes each `insert`ed entry as it is added, so a later patch in the same list can configure or disable a row an earlier patch inserted; upstream built the id index once before the patch loop, leaving inserted rows silently unpatchable. That matters because `dsh` composes an empty profile root with each bundle's patch layer, the profile's and the home-level `cordis.patch.yml`, and any `--patch` overlays as sibling patch lists at one include level — patches never cross an include boundary, so surface-only rows would otherwise be unreachable from user config. Covered by `packages/boot/app-boot/tests/config-reload.spec.ts`.
 13. **`include/src/index.ts` serialized child-tree mutation and `hmr/src/index.ts` main-watcher initial-scan suppression**: every Include child-tree mutation (initial apply, refresh, `internal/update` patch re-application) runs through one per-Include queue, because the group's transactional `update` is not reentrant — two concurrent applies interleave create and rollback on the same entries and strand the Include fiber without ever settling. The HMR main watcher passes `ignoreInitial: true`: the initial scan re-announced files boot had just consumed, and its `add` for a config file refreshed an Include mid-initial-apply; once serialized, a failing initial apply's rollback disposed HMR, whose teardown drain waited on the queued refresh sitting behind that same apply — a deadlock that exited 13 with no diagnostic. `registerConfig()` keeps its own `ignoreInitial: false` watcher because a user patch layer present at registration must apply once. Covered by the patch-overlay boot-failure built-bin case in `apps/cli/tests/built-bin.e2e.ts`.
