# Git Archaeologist Skill

Analyzes Git repository history to understand code evolution, find when bugs were introduced, and identify problematic commits.

## What It Does

1. **Bug Origin Finding**: Identify when and how a bug was introduced
2. **Code Evolution Analysis**: Understand how code changed over time
3. **Author Attribution**: Who wrote/modified specific code
4. **Hotspot Detection**: Files that change frequently

## Quick Commands

```bash
# Git bisect to find bad commit
git bisect start
git bisect bad
git bisect good v1.0.0

# File history
git log --oneline --follow filename.py

# Who changed file most
git log --format="%an" --follow -- filename.py | sort | uniq -c | sort -nr
```

## Usage

```
"Find when this bug was introduced"
"Who wrote the authentication module?"
"Show me commits that touched this function"
```
