DeepSeek Open-Sources Agent Harness Framework: Everything is a Plugin

AccBalanced · x · 2026-08-14

DeepSeek has announced the developer preview of DeepSeek Harness v0.1, now open-sourced under the MIT license. Built on the Cordis meta-framework, it is an agent harness centered around the core philosophy: "Everything is a plugin."

In this framework, all components—including models, tools, skills, sessions, sandboxes, filesystems, loops, orchestration, and UI—are implemented as plugins. This architecture allows developers to easily mix, match, replace, and extend functionalities.
