The extension, available on the VS Code Marketplace, requires VS Code 1.100 or newer and Node.js ^22.19 or >=24, and supports project-aware context, session controls, native review, and extension management.", "body_md": "Note\n\n⭐ Like DSH Sidebar? [Give it a Star on GitHub](https://github.com/Lixxx1/dsh-vscode)! It helps more people find the project.\n\nBring DeepSeek Harness into the same place you write code. dsh-vscode gives DSH a Claude Code/Codex-style right sidebar that already understands your project, active file, and selected code.\n\nAsk DeepSeek to inspect, change, and verify code without switching between your editor, terminal, and a separate chat window.\n\n👋 I built this because I wanted DSH right beside my editor. If that sounds useful to you too, give it a try! I'd love to hear how it fits into your workflow.\n\n**English** | [简体中文](/Lixxx1/dsh-vscode/blob/main/README.zh.md)\n\n**Official DSH inside VS Code.** Sessions, streaming responses, tool calls, approvals, and follow-up questions run through the official DSH runtime.**Project-aware editor context.** The active file, selected code, and`@file`\n\nor`@folder`\n\nreferences travel with your prompt.**Session controls where you need them.** Switch Permission and Plan modes, choose Model and Reasoning Effort, or steer an active task.**Native review and safe revert.** Review changes in VS Code's Diff Editor, Keep or Revert edits, and stop DSH before it overwrites a file with unsaved changes.**Extend DSH from the sidebar.** Discover and manage Tools, Skills, MCP integrations, Memory, and Agent Hooks loaded by DSH.\n\nInstall the official DeepSeek Harness CLI:\n\n```\nnpm install -g @deepseek-ai/dsh\n```\n\nThen choose the extension channel that fits you:\n\nOpen **Extensions** in VS Code, search for **DSH Sidebar**, and select **Install**. You can also install it from the [VS Code Marketplace](https://marketplace.visualstudio.com/items?itemName=lixxx1.dsh-sidebar).\n\nTo try features already available on `main`\n\nbut not yet published to the Marketplace, build and install the latest VSIX:\n\n```\ngit clone https://github.com/Lixxx1/dsh-vscode.git\ncd dsh-vscode\npnpm install --frozen-lockfile\npnpm run package\n```\n\nIn VS Code, run **Extensions: Install from VSIX...** from the Command Palette and select `dsh-vscode.vsix`\n\n. Development builds move faster and may be less stable; pull the latest changes and rebuild the VSIX to update.\n\nRequires VS Code 1.100 or newer and Node.js `^22.19`\n\nor `>=24`\n\n.\n\nInstalling community runtime plugins also requires `pnpm`\n\non your PATH.\n\n- Open a trusted project folder in VS Code.\n- Select\n**DeepSeek Harness** in the right sidebar. If it is hidden, find it under**Other Views**. - Use the key button to configure\n`DEEPSEEK_API_KEY`\n\n. - Choose the Permission mode, Model, and Reasoning Effort, then start working. Use the Shield menu for Permission and Plan modes,\n`/`\n\nfor official DSH commands, and`@`\n\nto add files or folders. - Use the plugins button in the sidebar title to search, install, inspect, or remove community runtime plugins.\n\n💬 Found a rough edge or have an idea for what should come next?
