Ядро Cordis
The Cordis kernel manages plugins: installing, uninstalling, and dependencies. Agent capabilities live in these plugins.
Developer preview · 0.1.2-rc.1
Локальный runtime агента Everything is a plugin
Models, tools, skills, sessions, sandboxes, storage, loops, scheduling и UI — каждый из них plugin, который можно заменить или собрать заново.
Web UI слушает 127.0.0.1:3080 через npx @deepseek-ai/dsh web. Лицензия MIT. Node.js ^22.19.0 или >=24. CLI распаковывается до 43 КБ на 0.1.2-rc.1.
Agent + model = Harness
HARNESS
keeps agents working in real-world environments
The model is the soul of an agent.
Harness даёт агенту читать среду, вызывать tools и работать вне чата.
Возможности как plugins
Plugins provide every agent capability, including models, tools, skills, sessions, sandboxes, storage, loops, scheduling, and the UI. Cordis services and events let the plugins work together.
Сборка через конфигурацию
Developers can select, swap, or extend any capability in configuration without changing the DeepSeek Harness source code.
Архитектура продукта
Собрано вокруг более простого workflow
Everything is a plugin
DeepSeek Harness построен на Cordis. Plugins дают models, tools, skills, sessions, sandboxes, storage, loops, scheduling и UI. Разработчики выбирают или расширяют возможность в конфигурации, а не форкают дерево. Официальный кадр Settings показывает 159 установленных строк.
Журнал сессии
Каждый запуск трассируется
Everything the model sees is recorded in an append-only session log: system prompts, reasoning, tool calls and results, subagent scheduling, and every context injection. In the Trajectory view, you can inspect these records by source. Resume, fork, search, and replay all operate on the same event stream.
Describe what you want to build
Пресеты runtime
Несколько режимов выполнения
Standard mode includes the full toolset. Code / PTC mode uses model-generated code to orchestrate multiple rounds of tool calls. Minimal mode keeps only a shell tool and a file editor for benchmarking models in a thin environment. Creator mode lets you inspect the current runtime, test Cordis plugins in memory, and combine them into new modes.
Get started

Операторы
Кто реально запускает dsh
- Авторы runtime агента меняют plugins модели, tool и sandbox, не правя исходники DeepSeek Harness.
- Операторы coding-агента pin @deepseek-ai/[email protected] и держите одноразовый workspace в режиме workspace-write плюс ask.
- Команды оценок берут Minimal mode (постоянный bash + str_replace_editor), когда нужна тонкая поверхность tools.
- Авторы presets используют Creator mode, чтобы гонять Cordis plugins в памяти до записи Profile.

Field notes

From discussions after real installs. Not marketing quotes.
Swapped the model plugin without touching the DeepSeek Harness tree. Cordis composition is the reason I stayed.
Discussion note · runtime author
Trajectory showed the exact bash payload that listed my workspace. Resume from that event worked. The UI still hiccups on very long streamed turns.
Discussion note · eval engineer
On Windows 11, C:\Windows\Temp plus windows-acl made every sandboxed pwsh call die with SandboxUnavailableError. Moving TEMP off the system temp dir fixed it.
Discussion note · Windows 11 Pro 25H2
npx brought the Web UI up in one command. Port 3080 was already reserved by Hyper-V, so I had to pick another port. That is in the port 3080 guide.
Discussion note · desktop lab
Creator mode is the only place I could inspect plugins in memory before writing a Profile. Token use on a multi-hour coding loop was higher than I budgeted.
Discussion note · preset builder
I pinned 0.1.1-rc.2 after an unpinned npx pull changed behavior overnight. The README warning is not decorative.

Короткий FAQ
DeepSeek Harness бесплатен?+
Yes. DeepSeek Harness is published under the MIT License as a developer preview. You can inspect, modify, and self-host it. Early 0.0.1-rc packages used BSD-3-Clause; current 0.1.x packages are MIT.
DeepSeek Harness работает на Windows 11?+
Yes, if Node.js is ^22.19.0 or >=24.0.0. The Windows sandbox uses an ACL restricted-token backend. Known issues include C:\Windows\Temp ACL lockouts, workspaces owned by BUILTIN\Administrators, and port 3080 reserved by Hyper-V, WSL2, or Docker.
DeepSeek Harness — это модель?+
No. DeepSeek Harness is the agent runtime around models. It supplies plugins for tools, sessions, sandboxes, storage, loops, scheduling, and the Web UI. Model IDs and API prices are separate releases.
Почему антивирус может пометить dsh?+
dsh is an npm CLI, not a Windows installer. Heuristic scanners sometimes flag Node processes that spawn shells. Check the published shasum for the version you pinned, such as fef213043313affc36ca2226d2637ad483b5e3f6 for 0.1.2-rc.1.
