+# ClaudeForge Changelog Generator
+
+ClaudeForge intelligent changelog and release notes generation system that automatically creates comprehensive, well-formatted changelogs from conventional commits, manages semantic versioning, and produces professional release documentation.
+
+## Purpose
+
+Transform changelog management from manual documentation to intelligent automation that ensures consistency, completeness, and professional presentation of project changes while maintaining semantic versioning standards.
+
+## Features
+
+- **Conventional Commits**: Parse and categorize commits following conventional commit format
+- **Semantic Versioning**: Automatic version bumping based on commit types
+- **Changelog Generation**: Generate CHANGELOG.md with proper formatting
+- **Release Notes**: Create detailed release notes for GitHub/GitLab releases
+- **Breaking Changes**: Highlight breaking changes prominently
+- **Multi-Format**: Support Markdown, HTML, JSON output formats
+- **Customization**: Configurable sections, templates, and formatting
+- **Integration**: GitHub/GitLab releases, npm version, and CI/CD integration
+
+## Usage
+
+```bash
+/changelog-generator [action] [options]
+```
+
+Target: $ARGUMENTS (if specified, otherwise analyze current scope)
+
+### Changelog Generation
+
+**Generate Changelog:**
+```bash
+/changelog-generator generate --from=v1.0.0 --to=HEAD --output=CHANGELOG.md
+```
+Generates comprehensive changelog with:
+- Conventional commit parsing (feat, fix, docs, style, refactor, test, chore)
+- Automatic categorization by commit type
+- Breaking changes section (BREAKING CHANGE footer)
+- Scope-based organization (api, ui, auth)
+- Author attribution and PR references
+- Commit links to repository
+- Comparison links between versions
+- Release date timestamps
+
+**Update Changelog:**
+```bash
+/changelog-generator update --version=2.1.0 --prepend=true
+```
+Updates existing CHANGELOG.md with:
+- New version section at the top
+- Preservation of existing content
+- Proper version header formatting
+- Date of release
+- Version comparison links
+- Unreleased section management
+- Consistent formatting throughout
+- Validation of markdown structure
+
+**Release Notes:**
+```bash
+/changelog-generator release-notes --version=2.1.0 --highlights=true
+```
+Creates release notes including:
+- Version number and date
+- Summary of key changes
+- Feature highlights with descriptions
+- Bug fixes and improvements
+- Breaking changes with migration guides
+- Deprecation notices
+- Security fixes (CVE references)
+- Contributors acknowledgment
+- Installation/upgrade instructions
+
+### Semantic Versioning
+
+**Version Bump:**
+```bash
+/changelog-generator bump --type=minor --dry-run=false
+```
+Determines version bump based on:
+- Major bump: BREAKING CHANGE commits or breaking: type
+- Minor bump: feat commits (new features)
+- Patch bump: fix commits (bug fixes)
+- Pre-release versions (alpha, beta, rc)
+- Version tagging in git
+- package.json version update
+- Changelog version synchronization
+- Automatic git tag creation
+
+**Next Version:**
+```bash
+/changelog-generator next-version --commits=origin/main..HEAD
+```
+Calculates next version by analyzing:
+- Commit history since last release
+- Conventional commit types
+- Breaking change indicators
+- Pre-release identifiers
+- Version constraints
+- Manual override options
+- Branching strategy (main, develop, feature)
+- Release candidate numbering
+
+**Version Validation:**
+```bash
+/changelog-generator validate-version --version=2.1.0-beta.3
+```
+Validates semantic version format:
+- Major.Minor.Patch format compliance
+- Pre-release identifier validity
+- Build metadata validation
+- Version comparison and ordering
+- Backward compatibility checks
+- Version range satisfaction
+- npm/yarn version compatibility
+- Consistency across package files
+
+### Commit Analysis
+
+**Parse Commits:**
+```bash
+/changelog-generator parse --range=v1.0.0..HEAD --format=json
+```
+Parses conventional commits with:
+- Type extraction (feat, fix, docs, etc.)
+- Scope identification (api, ui, core)
+- Subject/description parsing
+- Body content extraction
+- Footer parsing (BREAKING CHANGE, Closes, Refs)
+- Multi-line commit support
+- Co-authored-by extraction
+- Sign-off and trailer parsing
+
+**Validate Commits:**
+```bash
+/changelog-generator validate-commits --strict=true --from=HEAD~10
+```
+Validates commit message format:
+- Conventional commits specification compliance
+- Type allowlist enforcement
+- Scope validation against config
+- Subject line length limits (72 chars)
+- Body wrapping at 100 characters
+- Footer format validation
+- Breaking change syntax
+- Issue reference format
+
+**Commit Statistics:**
+```bash
+/changelog-generator stats --from=v1.0.0 --group-by=author
+```
+Generates commit statistics including:
+- Commit count by type
+- Top contributors
+- Commits per day/week/month
+- Breaking changes count
+- Average commit frequency
+- File change statistics
+- Lines added/removed
+- Most active areas/scopes
+
+### Customization
+
+**Configure Templates:**
+```bash
+/changelog-generator config --template=./changelog-template.hbs
+```
+Customizes changelog with:
+- Handlebars template support
+- Custom section headers
+- Commit grouping strategies
+- Formatting preferences (bullets, numbers)
+- Link format customization
+- Date format localization
+- Emoji support for commit types
+- Custom footer content
+
+**Section Configuration:**
+```bash
+/changelog-generator configure-sections --preset=angular
+```
+Defines changelog sections:
+- Feature section (feat commits)
+- Bug Fixes section (fix commits)
+- Performance Improvements (perf)
+- Breaking Changes (BREAKING CHANGE)
+- Deprecations (deprecated)
+- Documentation (docs)
+- Chores and maintenance
+- Custom sections with patterns
+
+**Exclusion Rules:**
+```bash
+/changelog-generator exclude --pattern="^chore(release|deps)" --scopes=internal
+```
+Excludes commits from changelog:
+- Commit type exclusions (chore, style, test)
+- Scope-based filtering
+- Pattern matching for subjects
+- Bot commits (dependabot, renovate)
+- Merge commits
+- Revert commits
+- WIP commits
+- Internal changes

+
+## Best Practices
+
+### Commit Message Format
+- **Conventional Commits**: Follow conventional commits specification
+- **Clear Subjects**: Write clear, concise commit subjects (50 chars)
+- **Detailed Bodies**: Provide context in commit body when needed
+- **Breaking Changes**: Always document breaking changes in footer
+- **Issue References**: Link commits to issues with Closes/Fixes
+
+### Changelog Management
+- **Keep Updated**: Update CHANGELOG.md with every release
+- **Unreleased Section**: Maintain unreleased section for upcoming changes
+- **Consistent Format**: Use consistent formatting throughout
+- **Version Links**: Include comparison links between versions
+- **Date Stamps**: Always include release dates
+
+### Release Process
+- **Semantic Versioning**: Strictly follow semantic versioning rules
+- **Release Notes**: Create detailed release notes for each version
+- **Tag Creation**: Create git tags for all releases
+- **Automation**: Automate changelog generation in CI/CD
+- **Review Process**: Review generated changelogs before publishing
