dsh-tools-plugins: A Toolset for Transforming Vague Instructions into Structured Prompts

The DeepSeek Harness plugin uses the `optimize_prompt` tool to address unstable agent output quality caused by vague input instructions. This tool rewrites short instructions into structured prompts that include Role, Task, Constraints, and Output Format, improving execution determinism. Users can install and configure it via CLI, with support for manual invocation or automatic detection, making it suitable for improving the accuracy of agent task handling.
