DeepSeek Harness

DeepSeek Harness — Technology. definition: Open source (MIT) coding agent harness published by DeepSeek on August 13, 2026 in developer preview, `dsh` command, written in TypeScript, built on a vendored Cordis kernel. "Everything is a plugin" architecture: models, tools, skills, sessions, sandboxes, storage, loops, scheduling, and interface are all swappable via configuration. Append-only session log as the single source of model context, with the runtime invariant "model-visible means logged". Four modes: Standard, Code, Minimal, Creator. Started via `npx @deepseek-ai/dsh web`, Web UI on 127.0.0.1:3080. No compatibility promise: SESSION_FORMAT_VERSION at 0, backends rejecting old on-disk formats
