What is Which DeepSeek Harness You Actually Want?
DeepSeek Harness (dsh) is an open-source agent harness developed by DeepSeek AI, while this SpringBrand page is a technical guide and integration path for the official project. It wraps a configured model with a workspace, tools, permissions, session history, and an execution loop rather than training or hosting a model itself. Powered by Cordis, it treats models, tools, skills, sessions, sandboxes, storage, loops, scheduling, and the UI as replaceable plugins. Developers can run it locally through a Web UI or headless profile, and a published Python SDK provides programmatic access. Its main differentiator is that teams can compose and swap the harness architecture itself, although the project remains a developer preview with breaking changes expected.
How to use Which DeepSeek Harness You Actually Want?
Step 1: Install Node.js and launch the local Web UI with `npx @deepseek-ai/dsh web`. Step 2: In Settings, add a supported model-provider credential and choose a workspace directory. Step 3: Select a runtime mode or compose plugins, describe the task, then inspect the trajectory and reuse or fork the session as needed.
Which DeepSeek Harness You Actually Want's Core Features
Plugin-First Architecture: Swap models, tools, skills, sessions, sandboxes, storage, loops, scheduling, and UI components through configuration.
Cordis Kernel: Mount, unmount, and reconnect plugins with reversible registrations and explicit dependency tracking.
Multiple Runtime Modes: Use Standard, Code, Minimal, or Creator mode to match coding, benchmarking, or plugin-development workflows.
Traceable Session Log: Inspect an append-only event stream that supports trajectory views, resume, fork, search, and replay.
Sandbox and Approval Controls: Restrict filesystem effects and require explicit approval for operations that need wider permissions.
Local Web UI: Launch a browser interface on localhost for model setup, workspace selection, sessions, plugins, and runtime inspection.
Headless Runner: Execute one-shot agent tasks without running the Web UI server.
Multi-Provider Model Access: Configure DeepSeek, catalog providers such as Anthropic or OpenAI, native cloud providers, or custom OpenAI-compatible endpoints.
Python SDK: Call a programmatic harness API as an alternative to the browser-based workflow.
SpringBrand MCP Connection: Add SpringBrand marketplace capabilities through its OAuth 2.1 Streamable HTTP MCP client plugin.
