DSH Studio Real UI Main Workbench
▲ DSH Studio Authentic Full-Stack Workbench UI: Multi-model chat, enhanced geek sidebar, mascot companion & real-time token probe

--- ## 🆚 What is Added over Upstream DeepSeek Harness (DSH)? While upstream **DeepSeek Harness (DSH)** provides the low-level Agent runtime loop and CLI kernel, **DSH Studio** is the **full-stack industrial-grade enhanced workbench and micro-frontend ecosystem**: | Dimension | Upstream DeepSeek Harness (DSH) | 🌟 **DSH Studio (Real Features)** | | :--- | :--- | :--- | | **🌐 Remote SSH & Terminal** | ❌ Basic local subprocess only, no persistent terminal, no remote SSH | ✅ **Integrated Remote SSH Direct Connection & ConPTY / PTY Terminal**, multi-tab support & **8 Dedicated Agent Terminal Tools** | | **🧰 IDE-Grade Workflow** | ❌ Chat-only conversation window, no file browsing or git diff | ✅ **Industrial Enhanced Sidebar**: Explorer syntax-highlighted code preview & search, Git branch switching, visual commit log & Diff | | **🔌 MCP Discovery** | ❌ Manual single JSON file editing only | ✅ **All-Source Auto Discovery** (`.vscode`, Cursor, Claude, Antigravity) + 10+ Curated Official Presets Carousel | | **🧪 MCP Online Sandbox** | ❌ None, requires prompting LLM with token cost | ✅ **Tool Tester Sandbox** (Schema form generation, 1-click test mock data, real RPC handshake & **0 Token Millisecond Latency Probe**) | | **🧠 Visual CoT Reasoning** | ❌ Cannot stream multimodal `reasoning_content`, prone to blank screens | ✅ **Native CoT Vision Engine** (Stream-captures Xiaomi MiMo deep thinking chains with foldable typewriter rendering) | | **🐬 Mascot Companion** | ❌ None, idle waiting during long generation | ✅ **Little Whale Maid 2.0** (3 HD skins + **650ms Speed CET-4 Blind Flashcards** + snack feeding CD system + retro mini-arcade) | | **💰 Cost Transparency** | ⚠️ Single-session rough estimation only, lost on refresh | ✅ **All-Time Billing Ledger (Persistent)** + Real-time token bottom probe + Monthly dynamic budget progress bar | | **🧩 Extensibility** | Static single-bundle composition | **Hot-pluggable Micro-frontend Plugins** + Drag-and-drop customizable sidebar card tabs | --- ## 🌟 Core Features & Real Screenshots ### 🧰 1. Industrial-Grade Enhanced Sidebar & Remote SSH Terminal (`dsh-better-sidebar`) An all-in-one developer productivity suite for full-stack engineering and operations:

DSH Real Sidebar and Tool Panels
▲ Authentic Screenshot: Multi-function enhanced sidebar tabs, task boards, and workflow cards

* **🌐 Remote SSH Sessions & Embedded Persistent PTY Terminal**: - Multi-tab terminal management (Local Bash / PowerShell / WSL / **Direct Remote SSH Host Sessions**); - Auto-reconnect and immersive full-screen terminal mode; - **8 Built-in Agent Terminal Tools**: `terminal_create`, `terminal_send`, `terminal_read`, `terminal_wait_for`, `terminal_resize`, `terminal_signal`, `terminal_close`, `terminal_list`, empowering autonomous AI agents to operate local and remote servers effortlessly. * **📁 Explorer & Code Syntax Preview**: - Tree-structured workspace file navigation and fast search; - Real-time syntax-highlighted code previews (Rust, Go, Python, TypeScript, C++, SQL, YAML, JSON and 15+ languages). * **🌿 Source Control (Git) & Visual Commit Log**: - Branch switching and working directory state tracking; - Visual commit history inspection and file Diff highlighting with one-click revert. --- ### 🔌 2. MCP Multi-Source Management & Online RPC Testing Sandbox (`dsh-better-sidebar-mcp`) Click "MCP Management" in the sidebar to access full-suite configuration sniffing, 10+ official presets carousel, and the isolated **Tool Tester Online Sandbox**:

* **Multi-Source Auto-Aggregation**: Automatically scans and detects workspace configs (`./mcp.json`, `.vscode/mcp.json`, `.cursor/mcp.json`, `.agents/mcp_config.json`) and global environments (Claude Desktop, Cursor, Antigravity/Gemini, `~/.dsh/mcp.json`). * **Single Tool Online Testing Sandbox (Tool Tester Modal)**: Renders dynamic parameter forms from JSON Schema, populates default mock data with one click, **executes real JSON-RPC handshakes**, and displays millisecond latency and structured returns **with zero LLM token cost**. * **10+ Curated Official Presets Carousel**: Built-in GitHub, SQLite, Web Fetch, Brave Search, Puppeteer, PostgreSQL, Memory, Filesystem, Everything, Git presets with horizontal scroll and quick switches. * **Bulk JSON Import & Live Toggles**: Paste raw `mcpServers` JSON snippets for instant parsing and toggle servers on/off non-destructively. --- ### 🧠 3. CoT Visual Reasoning Stream Penetration Engine (`dsh-tool-describe-image`) Engineered for multimodal vision models with deep thinking, unlocking loss-free reasoning chain streaming and network benchmarking: * **Chain of Thought (CoT) Compatibility**: Tailored for models with deep reasoning (e.g., Xiaomi MiMo). Even when initial stream `content` is empty, it parses `reasoning_content` without latency or timeout. * **Graphical Connectivity Probing**: Measure endpoint round-trip times and automatically probe and list provider models. --- ### 🐬 4. Little Whale Maid 2.0 Geek Mascot & Companion (`dsh-mascot-pet`) An interactive desktop companion docked to your workspace, fusing flashcard study, geek memes, snack feeding, and global billing ledgers:
