DeepSeek Harness
DeepSeek Harness on AgentSky: DeepSeek's official first-party coding agent in the cloud. It runs in a persistent cloud computer, defaults to DeepSeek V4 Pro, and is billed by compute time and model tokens.
DeepSeek Harness (DSH) is DeepSeek's first-party agentic coding assistant, tuned to work natively with its verified DeepSeek, Kimi, GLM, and Grok model set. It is the only harness purpose-built for DeepSeek's model architecture and correctly handles DSH's SSE tool-name assembly, which generic wrappers do not.
