Deep Dive into DeepSeek's Open-Sourced Agent Harness DSH
dotey · x · 2026-08-14
An in-depth analysis of DeepSeek's first open-sourced agent harness, DSH. Unlike frameworks like Codex that use declarative plugins, DSH adopts an imperative model where plugins run directly within the process with their own state.
While this introduces complex lifecycle management (using the Cordis runtime for handling dangling references and hot updates), which might seem like over-engineering for average developers, its core goal is to enable runtime replaceability of the Agent Loop. In DSH, the control flow itself is a standard plugin, providing a foundational architecture for exploring self-evolving agents and multi-agent collaboration.
