DeepSeek Open-Sources Agent Framework deepseek-harness, Stars Top 130k
Around August 17, DeepSeek open-sourced its Agent framework deepseek-harness (dsh) under the MIT license, and GitHub stars quickly surpassed 130k. The framework is a middleware layer connecting models, tools, memory and interfaces, built on Cordis and 100% open source, providing a full stack for turning models into Agents.
Confirmed
- MIT-licensed and built on Cordis, with a core "everything is a plugin" philosophy: model providers, tools and skills, sandboxes and sessions are all pluggable and fully composable.
- Runs are traceable and replayable, with multiple runtime modes.
- Can orchestrate multi-vendor models, running Claude Code and Codex as sub-agents.
- @TheTuringPost highlighted that Agents can self-evolve during execution as one of its most distinctive features.
- Per @alexverem on August 19, GitHub stars exceeded 130k.
Community response
- Reddit user @kevinlu310 shared hands-on impressions, praising the "everything is a plugin" design and the underlying Cordis system for solving plugin installation and clean removal issues, and invited comparisons with other Agent frameworks.
- @RelevantEmergency707 posted a YouTube demo showing how the plugin architecture enables specific features and workflows.
Why it matters
- The composable "everything is a plugin" architecture with replayable runs offers a new path toward debuggable, evolvable Agents, directly addressing pain points around plugin install/uninstall residue.
- The ability to orchestrate existing agents like Claude Code and Codex as sub-agents positions it as a potential unified runtime for cross-vendor Agent orchestration.
