# Changelog Generator

This skill transforms technical git commits into polished, user-friendly changelogs that your customers and users will actually understand and appreciate.

## When to Use This Skill

- Creating weekly or monthly product update summaries
- Documenting changes for customers
- Writing changelog entries for app store submissions
- Generating update notifications
- Creating internal release documentation

## What This Skill Does

1. **Scans Git History**: Analyzes commits from a specific time period or between versions
2. **Categorizes Changes**: Groups commits into logical categories (features, improvements, bug fixes, breaking changes, security)
3. **Translates Technical → User-Friendly**: Converts developer commits into customer language
4. **Formats Professionally**: Creates clean, structured changelog entries
5. **Filters Noise**: Excludes internal commits (refactoring, tests, etc.)
