## What it is
Code Maat is a command line tool written in Clojure that mines and analyzes data from version-control systems to reveal technical, social, and organizational patterns in code evolution. It accompanies Adam Tornhill's books 'Your Code as a Crime Scene' and 'Software Design X-Rays', with its analyses since evolved into the commercial CodeScene product.

## Use cases
- mine git history to find hotspots with high change frequency
- detect technical debt from version-control data
- analyze code churn and complexity trends over time
- identify social and organizational coupling between modules
- find development bottlenecks in large codebases
- suggest refactoring directions based on actual code interactions
- export VCS analysis data for visualization

## When to choose
- you want to analyze repository history for hotspots and technical debt from the command line
- you're following the techniques in 'Your Code as a Crime Scene' or 'Software Design X-Rays'
- you need a scriptable, free tool for behavioral code analysis
- you want to run analyses as a Clojure library or via Docker

## When to avoid
- you want automated, GUI-based analyses with visualizations - use CodeScene instead
- you need actively developed features - the tool is in maintenance mode
- you need a tool without GPL v3 licensing constraints
- you need real-time code quality monitoring rather than historical analysis
