CC Plugin Forge

Purpose

Build and manage Claude Code plugins with correct structure, manifests, and marketplace integration. Includes workflows, automation scripts, and reference docs.

When to Use

• Creating new plugins for a marketplace
• Adding/modifying plugin components (commands, skills, agents, hooks)
• Updating plugin versions
• Working with plugin or marketplace manifests
• Setting up local plugin testing
• Publishing plugins

Getting Started

Create New Plugin

Use create_plugin.py to generate plugin structure:

python scripts/create_plugin.py plugin-name \
  --marketplace-root /path/to/marketplace \
  --author-name "Your Name" \
  --author-email "your.email@example.com" \

This automatically:

• Creates plugin directory structure
• Generates plugin.json manifest
• Creates README template
• Updates marketplace.json

Bump Version

Use bump_version.py to update versions in both manifests:

Semantic versioning:

• major: Breaking changes (1.0.0 → 2.0.0)
• minor: New features, refactoring (1.0.0 → 1.1.0)
• patch: Bug fixes, docs (1.0.0 → 1.0.1)

Development Workflow

1. Create Structure

Manual approach (if not using script):

2. Plugin Manifest

File: plugins/plugin-name/.claude-plugin/plugin.json

3. Register in Marketplace

Update .claude-plugin/marketplace.json:

4. Add Components

Create in respective directories:

5. Local Testing

Plugin Patterns

Framework Plugin

For framework-specific guidance (React, Vue, etc.):

Utility Plugin

For tools and commands:

Domain Plugin

For domain-specific knowledge:

Command Naming

Subdirectory-based namespacing with : separator:

• commands/namespace/command.md → /namespace:command
• commands/simple.md → /simple

Examples:

• commands/prime/vue.md → /prime:vue
• commands/docs/generate.md → /docs:generate

Version Management

Important: Update version in BOTH locations:

1. plugins/<name>/.claude-plugin/plugin.json
2. .claude-plugin/marketplace.json

Use bump_version.py to automate.

Git Commits

Use conventional commits:
