This is an unofficial, community-made visual guide. It is source-locked to DeepSeek Harness commit 47f9438, which corresponds to the dsh@0.1.0-rc.5 developer-preview release. The official repository remains the technical source of truth.
DeepSeek Harness is more than a model wrapper. It composes the model adapter, tool registry, session log, agent loop, permissions, and product entry points as replaceable runtime capabilities. This handbook turns those relationships into a visual learning path instead of duplicating the official documentation as another wall of text.
