DeepSeek Harness Prompt Optimization Plugin (zzy-dsh-prompt-optimizer)

The `zzy-dsh-prompt-optimizer` plugin is designed for DeepSeek Harness (DSH) to streamline the iterative optimization of prompts. It integrates into the DSH Web interface by adding a “Prompt Optimization” entry in the input box. The plugin supports three optimization modes (fidelity, developer-oriented expression, and specification expansion) and can access session and workspace context. Core features include directly populating the input with optimized results, one-click restoration of the original prompt, and configuration of model and character budget settings. It does not store API keys and only temporarily submits drafts for processing, with a focus on privacy and security. By using visualized interactions, the tool reduces the operational overhead for developers and is suitable for development scenarios that require frequent instruction tuning.
