DeepSeek's open-source dsh harness makes every part of a coding agent a swappable plugin

alex_verem · x · 2026-09-15

DeepSeek released a developer preview of DeepSeek Harness (dsh): one terminal command spins up a local web app with a coding agent. Everything — model adapter, tool registry, session log, agent loop — is a plugin with no protected core, so the model becomes just a setting and the sandbox can point at a remote machine. Anything the model sees must be written to the session log first, enforced at runtime, enabling forking, replay and audit. The repo has 225k stars and 15k commits.
