## What it does

The skill walks the git history since the last release and sorts commits into categories: `feat` lands in Added, `fix` in Fixed, `docs` in Documentation, `perf` in Performance, and anything marked `BREAKING CHANGE` gets its own block. Output follows the Keep a Changelog format, and the skill suggests the next semantic versioning bump — major, minor or patch.

A separate user-facing summary covers highlights, new features, fixes, changes, security and contributors. Breaking changes are detected from commit markers, a "breaking-change" PR label, config format changes and API endpoint edits. History is gathered with plain git commands, such as `git log $(git describe --tags --abbrev=0)..HEAD --oneline`.

Conventional commits give the cleanest result. Without a type prefix, a commit gets sorted more or less by guesswork, so on free-form messages you will want to review the categories yourself.

## When to use it
- build a CHANGELOG from commits since the last tag
- sort changes into Added, Fixed and Breaking Changes
- pick the next version bump under semantic versioning
- write release notes aimed at users, not developers
- spot breaking changes before a major release

## Example prompts
- create a changelog from commits since the last release
- write release notes for version 2.1.0
- prepare the release: group changes by type and suggest a version number

# Changelog & Release Notes Writer

Generate professional changelogs and release notes from version control history.

## Core Workflow

1. **Analyze commits**: Parse git history since last release
2. **Categorize changes**: Group by type (feat, fix, docs, etc.)
3. **Identify breaking changes**: Flag incompatible changes
4. **Extract highlights**: Surface most important changes
5. **Format document**: Follow Keep a Changelog format
6. **Suggest version**: Recommend semantic version bump
7. **Generate release notes**: Create user-friendly summary

## Commit Analysis

### Extract Information From

- Commit messages (preferably conventional commits)
- PR titles and descriptions
- Issue references (#123)
- Merge commit messages
- Commit authors

### Parse Patterns

```
feat(auth): add OAuth2 support
^    ^      ^
|    |      └─ Description
|    └─ Scope (optional)

- `fix` → Fixed
- `docs` → Documentation
- `style`, `refactor` → Changed
- `perf` → Performance
- `test` → Testing
- `chore`, `ci` → Internal
