Núcleo Cordis
The Cordis kernel manages plugins: installing, uninstalling, and dependencies. Agent capabilities live in these plugins.
Developer preview · 0.1.2-rc.1
Runtime de agente local Everything is a plugin
Models, tools, skills, sessions, sandboxes, storage, loops, scheduling y la UI son cada uno un plugin que puedes cambiar o recomponer.
La Web UI se enlaza a 127.0.0.1:3080 con npx @deepseek-ai/dsh web. Licencia MIT. Node.js ^22.19.0 o >=24. El CLI descomprime a 43 KB en 0.1.2-rc.1.
Agent + model = Harness
HARNESS
keeps agents working in real-world environments
The model is the soul of an agent.
Un harness deja que el agente lea su entorno, llame tools y siga trabajando fuera del chat.
Capacidades como 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.
Componer con configuración
Developers can select, swap, or extend any capability in configuration without changing the DeepSeek Harness source code.
Arquitectura del producto
Construido en torno a un flujo más simple
Everything is a plugin
DeepSeek Harness está construido sobre Cordis. Los plugins aportan models, tools, skills, sessions, sandboxes, storage, loops, scheduling y la UI. Los desarrolladores eligen o extienden una capacidad en configuración en vez de hacer fork del árbol. El frame oficial de Settings lista 159 filas instaladas.
Registro de sesión
Cada ejecución es trazable
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
Presets de runtime
Varios modos de ejecución
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.

Operadores
Quién ejecuta dsh de verdad
- Autores del runtime de agente cambian plugins de model, tool y sandbox sin editar el código de DeepSeek Harness.
- Operadores del agente de código pin @deepseek-ai/[email protected] y mantén un workspace desechable bajo workspace-write más ask.
- Equipos de eval usan Minimal mode (bash persistente + str_replace_editor) cuando quieren una superficie de tools delgada.
- Constructores de presets usan Creator mode para probar plugins Cordis en memoria antes de escribir un Profile.

Field notes
Notas de quienes ya lo ejecutaron
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.

Preguntas breves
¿DeepSeek Harness es gratis?+
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 funciona en 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 es un modelo?+
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.
¿Por qué podría el antivirus marcar 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.
