dsh-0-tools: A Zero-Barrier, Zero-Cost Integration Suite for DeepSeek Harness

`dsh-0-tools` is a community plugin designed specifically for DeepSeek Harness (DSH), aiming to lower the barrier to use. Maintained by `ai-yukin`, it provides one-click environment setup and access to four free Chinese models (such as Zhipu and SiliconFlow). Its core features include an automatic speed-test and selection mechanism that monitors model responsiveness in real time and suggests switching; real-time reminders for official DeepSeek billing time slots (showing full price or half price); and a built-in help center. Users can quickly install it on Windows, macOS, and Linux using the provided scripts, and after pasting an API key, the configuration is automatically detected, enabling low-cost and high-efficiency access to large models.
