dsh-reply-language: A DSH Plugin That Forces Large Models to Reply in a Specified Language

`dsh-reply-language` is a DeepSeek Harness plugin maintained by CAI-MH. Through system prompt injection, it enforces a consistent language for the model's explanations, summaries, and error messages, while preserving code and technical terminology in their original form. Users can switch or query the current language at any time during a conversation using the `reply_language_set` and `reply_language_get` tools. The plugin defaults to Simplified Chinese, requires no configuration, and has a high priority, aiming to improve output consistency in multilingual scenarios.
