DeepSeek Harness (dsh)
DeepSeek's own open-source agent harness ('Everything is a Plugin') with web, desktop and SSH UI, plugins, subagents and MCP. It is a developer preview under MIT.
A plugin-based agent framework in TypeScript on the Cordis runtime, giving V4 a first-party coding and cowork front end. Releases since September add scheduled tasks, file diff review, Office previews and a Claude Code mods compatibility layer.

Open-source software, not model weights; 'access' reflects that. Launch date taken from repo creation; I found no dated announcement. README says breaking changes expected. The unusually fast star count is as reported by the GitHub API and was not independently audited.
