dsh-weneedfirst: DeepSeek Harness Plugin, Shaping the Chain of Thought

DeepSeek Harness (DSH)’s `dsh-weneedfirst` plugin is built on the core philosophy of “everything is a plugin,” aiming to govern the model’s chain of thought by injecting a global system prompt. It requires the model to think in English and start each reasoning block with a specific phrase (default: “What we need is”). No build step is required after installation; the plugin is automatically activated via `dsh bundle patch`, but the web application must be restarted after configuration changes or plugin updates. Stateless and lightweight, it supports customizing the starting phrase via a configuration file and is well suited to shaping the model’s reasoning behavior.
