Repomix Unmixer

If you've received a repository packed into a single XML, Markdown, or JSON file via repomix, this extracts everything back into its original directory structure. You run a Python script, point it at the packed file and an output directory, and it reconstructs all the individual files with their proper paths. Most useful when someone shares a Claude skill or codebase as a repomix file and you need to actually work with it. The skill defaults to using temporary directories for extraction, which is smart since you'll want to review what you're unpacking before moving it anywhere permanent. It's basically the reverse operation of repomix, straightforward and does one thing well.

Repomix Unmixer

Overview

This skill extracts files from repomix-packed repositories and restores their original directory structure. Repomix packs entire repositories into single AI-friendly files (XML, Markdown, or JSON), and this skill reverses that process to restore individual files.

When to Use This Skill

This skill activates when:

Unmixing a repomix output file (*.xml, *.md, *.json)
Extracting files from a packed repository
Restoring original directory structure from repomix format
Reviewing or validating repomix-packed content
Converting repomix output back to usable files

Core Workflow

Standard Unmixing Process

Extract all files from a repomix file and restore the original directory structure using the bundled unmix_repomix.py script:

python3 scripts/unmix_repomix.py \
  "<path_to_repomix_file>" \
  "<output_directory>"

Parameters:

<path_to_repomix_file>: Path to the repomix output file (XML, Markdown, or JSON)
<output_directory>: Directory where files will be extracted (will be created if doesn't exist)
