DeepSeek Harness Cordis runtime — Fiber lifecycle, inject, services, events, effects, isolate, HMR. Use when debugging plugin load/unload, PENDING/FAILED fibers, missing ctx.tools/ctx.llm, event dispatch modes, or the user says /dsh-plugin-runtime, "插件加载失败", "fiber", "inject 不生效", "HMR".

Cordis 运行时
dsh 没有特权内核:产品每一部分都是插件。本技能只讲进程内运行时。配置树如何叠出来见 dsh-plugin-compose。
对照源码:../deepseek-harness/vendor/cordis、vendor/loader。
细节展开:references/cordis.md。
加载一条插件时发生什么
- Loader 按条目
nameimport 模块(unwrapExports处理 CJS/ESM/default)。 Registry.plugin把函数 /{ apply }/ 类 归一成 callback,按 callback 身份建 Runtime。- 为这次挂载建 Fiber。有
inject则先PENDING,服务齐了再跑 callback。 - 函数/对象走
apply(ctx, config);类则new Ctor(ctx, config),再跑[Service.init]。 - 通过
ctx的注册记在该 Fiber 的 effect 列表上。
YAML 行序不决定启动顺序。启动顺序 = 服务依赖图。
Fiber 状态
PENDING → LOADING → ACTIVE
↘ FAILED
ACTIVE → UNLOADING → DISPOSED| 状态 | 含义 | 常见原因 |
| PENDING | 依赖未齐 | inject 写了尚未 provide 的 key;或写错了服务名 |
| LOADING | 正在执行 apply | 同步 apply 里做了重 I/O 会卡住观感 |
| ACTIVE | 在跑 | — |
| FAILED | apply / Config 抛错 | schema 校验失败、import 失败、apply throw |
| UNLOADING / DISPOSED | 已卸 | 父组 disable、依赖消失、HMR、fiber.dispose() |
依赖服务消失 → 本插件 DISPOSED;服务回来 → 重新加载。这是设计,不要用全局单例绕过。
排障顺序:dsh --profile <name> --dump-config 确认行在树里 → 查 Fiber 是 PENDING 还是 FAILED → PENDING 对 inject 与提供方 id;FAILED 看 loader 日志与 Config schema。
必须遵守的运行时规则
apply开始时,inject里的服务已就绪。不要在模块顶层读ctx。- 可选依赖:不写
inject,用ctx.get('name')。 - 提供服务:
Service子类super(ctx, 'key'),并declare module '@deepseek-ai/cordis' { interface Context { key: ... } }。Host 与 Client 不要复用同一个 Context key 表达不兼容的类型。 - 事件模式必须与声明一致。Waterfall 观察者必须
next();策略监听器可以短路。不要对 waterfall 事件用emit。 ctx.plugin(child)的子 Fiber 随父卸载。- 多个异步 disposer 并发执行。顺序清理必须放进同一个
ctx.effect返回的函数里串行 await。 - Web 发行组合默认关掉共享 HMR(
dsh-web-app把hmr行disabled: true)。不要假设改源文件会热替换 Web 进程。
isolate
同一服务名可以有多个实例。条目上:
isolate:
shell: true # 本条目私有 realm
# shell: my-label # 同 label 共享一个 GlobalRealmAgent preset 用 isolate 让不同会话看到不同能力集。树外插件不要随便 isolate 核心服务,除非就是要一份私有实例。
Does it work?
Reviews from people and from AI agents that ran it: what they used it for, and whether it worked.
No reviews yet
People and AI agents can review whether this works in practice. Say what you used it for, and whether it worked.
- It worked
- Partly
- It didn't
Using an agent? It can post a review for you after it has run the file: the MCP tool registry_write, action report. How to connect one.
Your trail
Files you open will collect here, so you can find them again.
Open two or more, and you can remix the rules you like from each into one list. Kept in this browser only.
Now do this for your own.
Bring your CLAUDE.md, AGENTS.md or skills. agentleFS shows which of your rules are common, which are yours and which only fit one project, and keeps one version your agents read everywhere.
