What is dsh-0-tools

dsh-0-tools is designed for users with zero programming experience who are using DeepSeek Harness (hereinafter referred to as DSH) for the first time. It features "Zero Barrier, Zero Cost, Zero Loss of Control, Zero Confusion", aiming to help beginners get a better user experience.

Main Features

1. [Zero Barrier] One-click installation of DSH and this tool, with automatic desktop shortcut creation;
2. [Zero Cost] One-click access to multiple permanently free large models accessible in China (Zhipu AI / SiliconFlow / iFlytek Spark / OpenRouter / ...), with automatic health monitoring and intelligent timeout prompts after configuration;
3. [Zero Loss of Control] If you choose to call the DeepSeek official model API, the DSH interface will display real-time reminders of whether it's peak hours (full price) or off-peak hours (half price);
4. [Zero Confusion] The beginner help center aggregates DSH official documentation and community-selected resources for quick onboarding.

Current Version & Compatibility

• Current version: v1.8.6
• Compatible DSH version: ≥ 0.1.7 (verified with 0.1.7-rc.2)
• System Requirements: One-click installation scripts support Windows 10 / Windows 11 (install.bat) and macOS / Linux (install.sh); the plugin core code itself is cross-platform. Users who have manually installed DSH can install the plugin manually via dsh plugin --profile web add /path/to/dsh-0-tools.

Free Model List

dsh-0-tools currently integrates 4 permanently free large models. We recommend configuring all of them — when one model is busy or reporting errors, you'll have more faster and more stable free models to choose from, achieving "the more models, the more switching options":

Model	Provider	Features
GLM-4.7-Flash + GLM-4V-Flash	Zhipu AI	Text + image understanding, permanently free
Qwen3-8B (15+ models under 9B)	SiliconFlow	Permanently free, direct access in China, 128K context, supports tool calling
Spark Lite	iFlytek Spark	Permanently free, strong Chinese understanding
OpenRouter Free Pool	OpenRouter	Automatically routes dozens of free models, automatically bypasses when one is delisted

Each model provides a dedicated illustrated tutorial page. Click "Guide Tutorial" in "① Zero Cost · Free Model Manager Center" to view step-by-step registration instructions.

Installation & Usage (Illustrated Steps)

Step 1: Run the One-Click Installation Script

• Windows users: Double-click to run install.bat
• macOS / Linux users: Run chmod +x install.sh && ./install.sh in the terminal

Windows Version (install.bat)

• If DSH is already installed on your computer: the script will automatically detect and skip the installation, directly completing the installation of this tool;
• If DSH is not installed yet: the script will automatically scan the runtime environment, fill in missing dependencies, and then automatically install DSH;
• After successful installation, the script will automatically create a "DeepSeek Harness" shortcut on your desktop.

Tip: install.bat is a plain text script. You can right-click → "Open with → Notepad" to view all content before running (content is transparent and auditable). Scripts downloaded from the internet don't have digital signatures, and Windows may pop up a SmartScreen prompt ("Windows protected your PC"). Click "More info → Run anyway" — this is Windows' unified prompt for unsigned scripts, not a virus warning.

Step 2: Open the DSH Interface

Double-click the "DeepSeek Harness" shortcut on your desktop, and the browser will automatically open the DSH web interface. When you haven't configured any free models yet, a popup will automatically guide you through configuration; you can also click the "Configure Free Model" button in the bottom-left corner of the DSH interface to enter the same configuration interface.

Step 3: Get and Install API Key

We recommend configuring all the following free models — the more free models, the more switching options! Click the "Guide Tutorial" button on each model card below, follow the steps to register and copy the API Key (for iFlytek, you need to copy both APIKey and APISecret, concatenated with an English colon), and paste it into the "Paste any model API Key here for automatic recognition" box, then click "Auto-recognize API Key and install free model with one click" to automatically install the free model.

Configured models will show a ✅ mark and provide "One-click uninstall model" (with secondary confirmation); unconfigured models show "Guide Tutorial →" link.

Step 4: Intelligent Health Monitoring + Timeout Prompts, Zero Cost More Transparent

After configuring 2 or more free models, dsh-0-tools' "Free Model Manager Center" will automatically start health monitoring:

• Automatic health monitoring: Every 60 seconds in the background, sends a minimal max_tokens=1 request to all configured free models for health checks, records the last 5 response times and averages them;
• Timeout prompt: When the current model times out, the bottom of the sidebar displays "Zhipu🔴Timeout, recommend switching to iFlytek" (automatically finds the fastest available model), helping users stay informed about model health;
• Status prompt: The bottom of the sidebar displays the current model status in real-time (Zhipu🟢Normal / Zhipu🟡Slow / Zhipu🔴Timeout, recommend switching to XX). The status bar is for display only and cannot be clicked;
• Status criteria: <8 seconds = Normal (🟢), 8-15 seconds = Slow (🟡), >15 seconds or timeout = Timeout (🔴).

Step 5: Using Paid DeepSeek Models

If you decide to use paid services and have already applied for and purchased a DeepSeek model API, you can click "Settings" in the bottom-left corner of the DSH interface, find "Models", click "Edit" next to DeepSeek, and enter your DeepSeek model API key.

Step 6: DeepSeek Billing Reminder

When you switch to and select a DeepSeek official model in the DSH interface, the bottom-left corner of the interface will display a real-time billing reminder. Based on the peak/off-peak hours of DeepSeek official API calls, it will prompt "Current peak hours, API at full price" or "Current off-peak hours, API at half price", providing you with "Zero Loss of Control" cost protection.

DeepSeek official billing rules (effective from 2026-08-23): Weekends (Saturday/Sunday) are uniformly off-peak pricing all day, no longer distinguishing peak/valley; only weekdays (Monday-Friday) implement peak/valley tiered billing — peak hours (9:00-12:00, 14:00-18:00) at full price, remaining off-peak hours at half price.

Mechanism Explanation

• Configuration status determination: The browser side calls official settings.describe + credentials.describe to determine whether llm-pi-ai.providers.{provider} exists and whether its credentials are configured, as the authoritative source; polls every 5 seconds to refresh the interface.
• One-click configuration: Sequentially writes credentials via official credentials.set, writes provider configuration section via settings.mutate, and switches the default model to the corresponding free model via settings.update with merge semantics (merge semantics ensure user-set fields like reasoningEffort are not erased).
• One-click uninstall: Clears the provider configuration section and corresponding credentials via official channels; only when the default model previously pointed to that provider, restores to the original default model recorded before configuration, otherwise keeps the user's current selection unchanged.
• API Key auto-recognition: Automatically identifies which model a Key belongs to based on prefix/format (sk-or-v1- → OpenRouter, sk- (non-sk-or-v1-) → SiliconFlow, APIKey:APISecret format or 32-bit hex → iFlytek Spark, long string with dots → Zhipu AI), and automatically invokes the one-click configuration process after recognition.
• Free Model Manager Center: Every 60 seconds in the background, sends max_tokens=1 minimal requests to all configured free models for health checks, records the last 5 response times and averages them; when the current model times out, intelligently prompts to recommend switching to the fastest available model; sidebar displays status in real-time (for display only, cannot be clicked).
• Invalid residual cleanup: The configuration center detects whether there are residual delisted/invalid model providers locally (dynamically reads their apiKeyEnv, no longer relying on local static lists), provides an "invalid residual" prompt in the interface and offers one-click cleanup, avoiding orphan configurations that cannot be deleted.
• Settings tab: Injected via settings.section slot (same mechanism as official plugins), id is dsh-0-tools, tab name is "dsh-0-tools".
• Help Center: Fetches https://ai-yukin.github.io/dsh-0-tools/help.json, passes through a unified filter filterRemotePayload for field-by-field security checks (URL enforces https, text rejects control characters/newlines, model id and credential name use character whitelist) before entering the interface and configuration chain; falls back to built-in data on failure or non-compliance; both the configurable model list and delisted model list are driven by this remote data, allowing adding or delisting models without reinstalling the plugin.
• Tutorial page hosting: Tutorial pages are uniformly hosted on GitHub Pages (https://ai-yukin.github.io/dsh-0-tools/guide/). Domestic users can download the source code from the Gitee mirror repository and view tutorials locally.
