DeepSeek Harness
By DeepSeek
Plugin-based agent harness that DeepSeek open-sourced on 13 August 2026 and which passed 165,000 GitHub stars in its first week, treating models, tools, skills, storage, and scheduling as interchangeable plugins so an agent gains capability through configuration instead of a source change.

- building agents on a plugin architecture rather than a fixed framework
- swapping models, tools, or storage backends through config
- running DeepSeek models in an agentic coding loop
- full logs of every model call for later review
- trying a harness through npx without cloning it
