Overview

DeepSeek Harness (dsh) is deepseek’s MIT-licensed, plugin-based open-source agent-harness (developer preview v0.1, Aug 13, 2026), positioned as a modular alternative to vertically integrated coding agents like claude-code and Codex.

Recent Developments

  • 2026-08-13: Launch — npx @deepseek-ai/dsh web; Cordis plugin architecture (“everything is a plugin”); breaking changes expected
  • Agent benchmarks for deepseek-v4-pro partly run in Harness “minimal mode” (company-reported)
