dsh-code-diff-viewer

When using DeepSeek Harness for code generation, the default tool cards provide basic diff previews lacking precise line numbers and clear visual contrast, often leading to misunderstandings. dsh-code-diff-viewer is designed to address this by transforming the Web interface's edit and write tool calls into professional code comparison panels, allowing developers to intuitively see code additions and deletions.

Its core strengths lie in "Absolute Line Numbers" and "Intelligent Layout." By using the Host-side interface to accurately reverse-engineer the real starting line of a hunk in the file, it solves the inaccuracy issues of the default context lines. Furthermore, it automatically switches between single-column (pure additions/deletions) and dual-column layouts based on change types, featuring built-in syntax highlighting for mainstream languages like JS/TS and Python, making every change crystal clear.

This plugin is ideal for developers who frequently use AI for code generation, particularly those using the DeepSeek Harness Web profile. It activates seamlessly with the process startup and provides high-quality code review experiences directly within the conversation flow, serving as an excellent visual enhancement tool to boost AI coding efficiency.
