Version-Manager Skill

Comprehensive version management utilities for semantic versioning automation.

Overview

This skill provides scripts, templates, and examples for automated version management using semantic versioning and conventional commits. It supports both Python and TypeScript/JavaScript projects with GitHub Actions CI/CD integration.

Components

Scripts

Functional bash scripts for version management operations:

• detect-project-type.sh - Detect Python vs TypeScript/JavaScript projects
• bump-version.sh - Calculate and update version in all files
• generate-changelog.sh - Extract commits and format changelog
• validate-version.sh - Verify version consistency across files
• create-git-tag.sh - Create annotated tag with changelog

Templates

Production-ready configuration templates:

• github-workflows/ - GitHub Actions workflows for Python and TypeScript
• VERSION.json - VERSION file template with metadata structure
• releaserc.json - Semantic-release configuration
• CHANGELOG.md - Keep a Changelog format template
• commit-templates.md - Conventional commit message templates

Examples

Realistic examples for common scenarios:

• conventional-commits.md - Example commit messages (feat, fix, breaking)
• changelog-entries.md - Example changelog formatting
• version-file.json - Example VERSION file with metadata
• workflow-outputs.md - Example GitHub Actions outputs
• bump-scenarios.md - Example version bump cases

Usage

Detecting Project Type

bash ~/.claude/plugins/marketplaces/dev-lifecycle-marketplace/plugins/versioning/skills/version-manager/scripts/detect-project-type.sh <project_dir> <output_file>

Output format (JSON):

{
  "project_type": "python|typescript|javascript",
  "manifest_file": "pyproject.toml|package.json",
  "has_typescript": true|false
}

Bumping Version

bash ~/.claude/plugins/marketplaces/dev-lifecycle-marketplace/plugins/versioning/skills/version-manager/scripts/bump-version.sh <bump_type> <current_version>

Bump types: major, minor, patch

Returns: New version string

Generating Changelog

bash ~/.claude/plugins/marketplaces/dev-lifecycle-marketplace/plugins/versioning/skills/version-manager/scripts/generate-changelog.sh <from_tag> <to_ref> <version>

Outputs formatted changelog to stdout.

Validating Version Consistency

bash ~/.claude/plugins/marketplaces/dev-lifecycle-marketplace/plugins/versioning/skills/version-manager/scripts/validate-version.sh <project_dir>

Checks VERSION file, pyproject.toml, package.json for consistency.

Exit codes:

• 0: All versions consistent
• 1: Version mismatch detected
• 2: Missing required files

Creating Git Tag

bash ~/.claude/plugins/marketplaces/dev-lifecycle-marketplace/plugins/versioning/skills/version-manager/scripts/create-git-tag.sh <version> <changelog_file>

Creates annotated git tag with changelog as message.

Templates Usage

GitHub Actions Workflow

Copy appropriate workflow template:

Python:

cp plugins/versioning/skills/version-manager/templates/github-workflows/python-version-management.yml .github/workflows/version-management.yml

TypeScript:

cp plugins/versioning/skills/version-manager/templates/github-workflows/typescript-version-management.yml .github/workflows/version-management.yml

Semantic-Release Configuration

Copy .releaserc.json template:

cp plugins/versioning/skills/version-manager/templates/releaserc.json .releaserc.json

Customize branches, plugins, and assets as needed.

Integration with Commands

This skill is used by versioning plugin commands:

• /versioning:setup - Uses detect-project-type.sh and workflow templates
• /versioning:bump - Uses bump-version.sh, generate-changelog.sh, create-git-tag.sh
• /versioning:info - Uses validate-version.sh
• /versioning:rollback - Uses version validation scripts

Integration with Agents

This skill provides utilities for versioning plugin agents:

• changelog-generator - Uses generate-changelog.sh for commit analysis
• release-validator - Uses validate-version.sh for consistency checks

Best Practices

1. Always validate before bumping versions
2. Use conventional commits for accurate changelog generation
3. Test workflows in CI/CD before releasing
4. Keep VERSION file in sync with manifests
5. Document breaking changes prominently in commits

Troubleshooting

Version Mismatch

If validation fails with version mismatch:

# Check all version locations
grep -r "version" VERSION pyproject.toml package.json

# Manually sync if needed
bash ~/.claude/plugins/marketplaces/dev-lifecycle-marketplace/plugins/versioning/skills/version-manager/scripts/bump-version.sh patch $(cat VERSION | jq -r '.version')

Changelog Generation Issues

If changelog is empty or incorrect:

# Verify commit format
git log --oneline --grep="^feat:" --grep="^fix:" -E

# Check tag exists
git tag -l "v*"

# Regenerate manually
bash ~/.claude/plugins/marketplaces/dev-lifecycle-marketplace/plugins/versioning/skills/version-manager/scripts/generate-changelog.sh v1.0.0 HEAD 1.1.0

Git Tag Creation Fails

If tag creation fails:

# Check if tag already exists
git tag -l v1.2.3

# Remove existing tag if needed
git tag -d v1.2.3

# Recreate tag
bash ~/.claude/plugins/marketplaces/dev-lifecycle-marketplace/plugins/versioning/skills/version-manager/scripts/create-git-tag.sh 1.2.3 CHANGELOG.md
