What are the technical requirements for this skill?

The skill requires Python 3.6 or higher, Git installed in your system PATH, and a terminal that supports ANSI color codes for the highlighting to display correctly.

Does it support viewing changes for specific files only?

Absolutely. You can provide an optional file or directory path as an argument to filter the diff output to only the parts of the project you are interested in.

Can I see my staged changes with this skill?

Yes, the skill specifically detects and displays staged changes (git diff --cached) first, followed by any unstaged changes in your working directory.

How is this different from the standard 'git diff' command?

While standard git diff provides raw text output, this skill formats the changes to look like the GitHub UI, adding dual-column line numbers and more readable color-coded blocks for better clarity.

Developer Tools

Visualizes git modifications using a high-readability, color-coded unified diff format with dual-column line numbers.

About

This skill enhances the code review experience within Claude Code by generating terminal output that mimics GitHub's unified diff interface. It provides clear, color-coded highlighting—red for deletions and green for additions—along with two-column line numbering to help developers track context effortlessly. By distinguishing between staged and unstaged changes, it serves as an essential tool for auditing code before commits, troubleshooting recent regressions, and performing local peer reviews without leaving the command line.

Key Features

Dual-column line numbering for precise code context
GitHub-style unified diff formatting with ANSI color support
Support for path-specific filtering to isolate changes in certain directories
Separate visualization for staged (--cached) and unstaged modifications
0 GitHub stars
Clean chunk markers and formatted file headers for faster navigation

Use Cases

Comparing current file modifications against the repository HEAD during debugging
Performing a final visual audit of code changes before pushing to a remote repository
Reviewing staged changes to ensure high-quality, atomic commits
