diffpilot is a small command-line tool that shows the differences between two files. It is designed to run inside a terminal window, with no browser tab and no separate graphical app. The README describes it as a side-by-side viewer with syntax highlighting, which means the two files are placed in two columns and the code is coloured so it is easier to read. The tool supports a few common ways of asking for a diff. You can pass it two file paths directly, you can ask it to show what is currently staged in git, or you can point it at two git branches and have it compare them. There is also an option to ignore whitespace, which is useful when the only differences between two files are spaces or tabs. The feature list in the README mentions syntax colouring for more than 50 programming languages, line numbers with markers next to changed lines, keyboard shortcuts for moving around, copying a section of the diff to the clipboard, and exporting the result as HTML or Markdown. Movement keys follow a vim-like style, with j and k to scroll, n and p to jump between changes, and q to quit. The repository also ships a folder of shell scripts under scripts/ that are not part of the diff tool itself. The README labels them as helpers for unlocking GitHub profile achievements, with names like quickdraw, yolo, publicist, and pull-shark. A separate Node script tracks which achievements have been earned. These are bundled alongside the diff viewer but serve a different purpose.
