The most agentic harness
for DeepSeek V4
- Rules, tools, evidence, and feedback loops that help the model keep working until the task is done. 1M-token context, thinking-mode streaming, OS-level sandboxing — single binary, zero dependencies.

- ▸How the harness works
-Constitutional hierarchy
-User intent outranks stale memory. Live evidence outranks assumptions. A clear chain of authority every turn.
-Structured trust
-Plan (read-only), Agent (approval-gated), YOLO (auto-approved). OS-level sandboxing backs every boundary.
-Feedback beats
-Failed commands and failing tests are not dead ends — they're signals the model can tune against, turn after turn.
-Continuity
-Memory persists across sessions. Handoffs survive compaction. Save, resume, and fork conversations.
-Distributed work
-Sub-agents run concurrently, up to 20 at a time. Results arrive as structured completion events.
-Right-size intelligence
-Fin handles routing and summaries. Pro engages for architecture and debugging. The right amount of intelligence for each problem.
-◎China / mirror-friendly install
-If downloads from GitHub or npm are slow from mainland China, use one of these paths:
- -npm via 淘宝镜像 (fastest)
-npm config set registry https://registry.npmmirror.com
-npm install -g deepseek-tui
- The npm wrapper itself will still download the binary from GitHub Releases during postinstall. If that step is slow, set a mirror for the binary download:
DEEPSEEK_TUI_RELEASE_BASE_URL=https://your-mirror.example.com \
- npm install -g deepseek-tui
- Cargo via 清华 TUNA mirror
-Add to ~/.cargo/config.toml:
[source.crates-io]
-replace-with = "tuna"
-
-[source.tuna]
-registry = "sparse+https://mirrors.tuna.tsinghua.edu.cn/crates.io-index/"
- Then install both binaries:
-cargo install deepseek-tui-cli --locked # provides `deepseek`
-cargo install deepseek-tui --locked # provides `deepseek-tui`
-deepseek --version
- Rustup mirror (for building from source)
-export RUSTUP_DIST_SERVER=https://mirrors.tuna.tsinghua.edu.cn/rustup
-export RUSTUP_UPDATE_ROOT=https://mirrors.tuna.tsinghua.edu.cn/rustup/rustup
-curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh
