dsh-quiet-mode: Inject Fixed Operational Discipline into DeepSeek Harness Model Requests

dsh-quiet-mode is a client plugin for DeepSeek Harness designed to eliminate the need for manually adding repetitive constraints by automatically injecting a fixed “work discipline” system prompt into each model request. The plugin supports customized injected content and allows flexible configuration through a configuration file. Users must ensure their environment meets Node.js 22.19 or 24 or later, and the service must be restarted after installation for the plugin to take effect.
