Version Bumper

Version Bumper

Purpose

Automatically manages semantic version updates for Claude Code plugins, ensuring consistency across plugin.json, marketplace catalog, and git tags - optimized for claude-code-plugins repository workflow.

Trigger Keywords

• "bump version" or "update version"
• "release" or "new release"
• "major version" or "minor version" or "patch version"
• "increment version"
• "version update"

Semantic Versioning

Format: MAJOR.MINOR.PATCH (e.g., 2.1.3)

Rules:

• MAJOR (2.x.x) - Breaking changes, incompatible API changes
• MINOR (x.1.x) - New features, backward compatible
• PATCH (x.x.3) - Bug fixes, backward compatible

Examples:

• 1.0.0 → 1.0.1 (bug fix)
• 1.0.0 → 1.1.0 (new feature)
• 1.0.0 → 2.0.0 (breaking change)

Version Bump Process

When activated, I will:

1. Identify Current Version

   # Read plugin version
   current=$(jq -r '.version' .claude-plugin/plugin.json)
   echo "Current version: $current"
   

2. Determine Bump Type

   • From user request (major/minor/patch)
   • Or suggest based on changes
   • Or ask user which type

3. Calculate New Version

   # Example for patch bump: 1.2.3 → 1.2.4
   IFS='.' read -r major minor patch <<< "$current"
   new_version="$major.$minor.$((patch + 1))"
   

4. Update Files

   • Update .claude-plugin/plugin.json
   • Update .claude-plugin/marketplace.extended.json
   • Sync to marketplace.json

5. Validate Consistency

   • Verify all files have same version
   • Check no other plugins use this version
   • Validate semver format

6. Create Git Tag (Optional)

   git tag -a "v$new_version" -m "Release v$new_version"
   

Update Locations

1. Plugin JSON

// .claude-plugin/plugin.json
{
  "name": "plugin-name",
  "version": "1.2.4",  // ← Update here
  ...
}

2. Marketplace Extended

// .claude-plugin/marketplace.extended.json
{
  "plugins": [
    {
      "name": "plugin-name",
      "version": "1.2.4",  // ← Update here
      ...
    }
  ]
}

3. Sync CLI Catalog

npm run sync-marketplace
# Regenerates marketplace.json with new version

Bump Types

Patch Bump (Bug Fix)

When to use:

• Bug fixes
• Documentation updates
• Minor improvements
• No new features

Example: 1.2.3 → 1.2.4

Minor Bump (New Feature)

When to use:

• New features
• New commands/agents/skills
• Backward compatible changes
• Enhanced functionality

Example: 1.2.3 → 1.3.0

Major Bump (Breaking Change)

When to use:

• Breaking API changes
• Incompatible updates
• Major refactor
• Removed features

Example: 1.2.3 → 2.0.0

Validation Checks

Before bumping:

• ✅ Current version is valid semver
• ✅ New version is higher than current
• ✅ No other plugin uses new version
• ✅ All files have same current version
• ✅ Git working directory is clean (optional)

After bumping:

• ✅ plugin.json updated
• ✅ marketplace.extended.json updated
• ✅ marketplace.json synced
• ✅ All versions consistent
• ✅ CHANGELOG.md updated (if exists)

Changelog Management

If CHANGELOG.md exists, I update it:

# Changelog

## [1.2.4] - 2025-10-16

### Fixed
- Bug fix description
- Another fix

## [1.2.3] - 2025-10-15
...

Git Integration

Option 1: Version Commit

# Update version files
git add .claude-plugin/plugin.json
git add .claude-plugin/marketplace.extended.json
git add .claude-plugin/marketplace.json
git add CHANGELOG.md  # if exists

# Commit version bump
git commit -m "chore: Bump plugin-name to v1.2.4"

Option 2: Version Tag

# Create annotated tag
git tag -a "plugin-name-v1.2.4" -m "Release plugin-name v1.2.4"

# Or for monorepo
git tag -a "v1.2.4" -m "Release v1.2.4"

# Push tag
git push origin plugin-name-v1.2.4

Multi-Plugin Updates

For repository-wide version bump:

# Bump marketplace version
jq '.metadata.version = "1.0.40"' .claude-plugin/marketplace.extended.json

# Update all plugins (if needed)
for plugin in plugins/*/; do
  # Update plugin.json
  # Update marketplace entry
done

Version Consistency Check

I verify:

# Plugin version
plugin_v=$(jq -r '.version' plugins/category/plugin-name/.claude-plugin/plugin.json)

# Marketplace version
market_v=$(jq -r '.plugins[] | select(.name == "plugin-name") | .version' .claude-plugin/marketplace.extended.json)

# Should match
if [ "$plugin_v" != "$market_v" ]; then
  echo "❌ Version mismatch!"
  echo "Plugin: $plugin_v"
  echo "Marketplace: $market_v"
fi

Release Workflow

Complete release process:

1. Determine Bump Type

   • Review changes since last version
   • Decide: patch/minor/major

2. Update Version

   • Bump plugin.json
   • Update marketplace catalog
   • Sync marketplace.json

3. Update Changelog

   • Add release notes
   • List changes
   • Include date

4. Commit Changes

   git add .
   git commit -m "chore: Release v1.2.4"
   

5. Create Tag

   git tag -a "v1.2.4" -m "Release v1.2.4"
   

6. Push

   git push origin main
   git push origin v1.2.4
   

7. Validate

   • Check GitHub release created
   • Verify marketplace updated
   • Test plugin installation
