 Shared prerequisite mounting for tests that exercise the concrete `AgentLoop`. `mountAgentLoopTestDependencies(ctx, options?)` installs the LLM, session, system-prompt, tool, and agent services in dependency order, then returns before the loop is mounted.
 
 The caller registers adapters and optional plugins, mounts `AgentLoop` with the configuration under test, and disposes its own Context. System-prompt and tool-registry configuration can be forwarded through `options`; the helper does not provide test defaults beyond those owned by the services. A plugin-load failure rejects the helper call, while services activated earlier in the sequence remain owned by the caller's Context.

+为测试具体 `AgentLoop` 的测试挂载共享先决条件。`mountAgentLoopTestDependencies(ctx, options?)` 按依赖顺序安装 LLM、会话、系统提示词、工具和 agent 服务，然后在 loop 挂载前返回。
+
+调用方注册适配器和可选插件，使用待测配置挂载 `AgentLoop`，并 dispose 自己的 Context。系统提示词和工具注册表配置可通过 `options` 转发；辅助工具不提供超出服务自有默认值的测试默认值。插件加载失败会拒绝辅助工具调用，而顺序中较早激活的服务仍归调用方的 Context 所有。
+
+```ts
+import { Context } from 'cordis'
+import AgentLoop from '@deepseek-ai/dsh-agent-loop'
+import { mountAgentLoopTestDependencies } from '@deepseek-ai/dsh-agent-loop-testkit'
+
+const ctx = new Context()
+
+await mountAgentLoopTestDependencies(ctx)
+// Register the test adapter and any optional plugins here.
+await ctx.plugin(AgentLoop, { agents: [] })
+```
+
+针对注入失败、部分拓扑、服务加载顺序或服务拆卸的测试会直接挂载其依赖，而不使用此辅助工具。
+
+## 模型体验
+
+无。该测试专用组合辅助工具既不驱动也不修改模型请求。
+
+#### KV 缓存影响
+
+无；该包既不组装也不发送提供方请求。
+
+## 已知限制与待完成工作
+
+- **只共享必需的先决主干**：适配器、可选插件、`AgentLoop`、agent 和 Context 拆卸仍由调用方负责，以使场景专用顺序保持可见。
