Install Learn Dsh

No package.json found — installability could not be checked.

Not checked — and that is not the same as fine

We could not find a package.json for this repository, so none of the publish spec rules could be applied. We do not know whether dsh plugin add activates anything here.

Best-effort git install — unverified, may activate nothing

# 1. add the bundle to a profile — --profile my-profile points at $DSH_HOME/profiles/my-profile
dsh plugin --profile my-profile add github:onychen/learn-dsh

# 2. verify: the bundle should show up as a layer in the resolved config
dsh --profile my-profile --dump-config

# 3. boot the profile
dsh --profile my-profile

Step 2 is the one that matters here: if --dump-config shows no new layer after the install, this repository is not a bundle and there is nothing to activate.

Before you run it

A plugin runs with your permissions once loaded: it can read your files, use your credentials and reach the network. Tool approvals do not sandbox it.
Installing from git resolves a moving branch. Pin a commit — github:onychen/learn-dsh#<commit-sha> — so the code you reviewed is the code you install.

Prerequisites

API key: Required — see the repository README for which provider.
Network access: Not required at runtime.
Language: JavaScript

> 仿照 [learn-claude-code](https://github.com/shareAI-lab/learn-claude-code) 的渐进式教学风格， > 但**主线来自 DeepSeek Harness 自己的架构分层**，而不是照搬那 12 课。 DeepSeek Harness（下称 **dsh**）的世界观和"一个 while 循环里不断加东西"截然不同。它的骨架只有几条： - **一切皆插件（Cordis）**：没有可打补丁的"特权核心"。模型适配器、工具注册表、会话日志、甚至 agent loop 本身都是插件，向共享的 `ctx` 贡献服务、类型化事件和可回退副作用。 - **仅追加的 SessionEvent 日志是唯一真源**：模型看到的历史不是单独存的，而是用 `deriveMessages()` 从事件日志**投影**出来的。"模型可见即已记录"。 - **Turn / Step 轮次**：`step` = 一次模型请求 + 它触发的工具调用；`turn` = 零或多个 step。 - **能力 seam**：一个可替换能力 = interface + implementation + consumer 三角色。换一个 provider 就能整体换掉产品的一块能力。 - **可选能力挂在 seam 上，不进 loop 主干**：subagent、compaction、skills、jobs、goal 都是可选能力，各自是独立机制，不属于 agent loop 核心。 **和 learn-claude-code 最本质的区别**：原版是"循环不变、能力层层叠加"； dsh 是"**内核极薄、一切经由插件树 + 事件 + seam 组合**"。所以本课主线不是"往循环里塞功能"，而是"**先立起 Cordis 插件/事件/sea
