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" \
  --description "Plugin description" \
  --keywords "keyword1,keyword2" \
  --category "productivity"

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:

python scripts/bump_version.py plugin-name major|minor|patch \
  --marketplace-root /path/to/marketplace

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):

mkdir -p plugins/plugin-name/.claude-plugin
mkdir -p plugins/plugin-name/commands
mkdir -p plugins/plugin-name/skills

2. Plugin Manifest

File:

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

{
  "name": "plugin-name",
  "version": "0.1.0",
  "description": "Plugin description",
  "author": {
    "name": "Your Name",
    "email": "your.email@example.com"
  },
  "keywords": ["keyword1", "keyword2"]
}

3. Register in Marketplace

Update

.claude-plugin/marketplace.json
:

{
  "name": "plugin-name",
  "source": "./plugins/plugin-name",
  "description": "Plugin description",
  "version": "0.1.0",
  "keywords": ["keyword1", "keyword2"],
  "category": "productivity"
}

4. Add Components

Create in respective directories:

ComponentLocationFormat
Commands
commands/
Markdown with frontmatter
Skills
skills/<name>/
Directory with
SKILL.md
Agents
agents/
Markdown definitions
Hooks
hooks/hooks.json
Event handlers
MCP Servers
.mcp.json
External integrations

5. Local Testing

# Add marketplace
/plugin marketplace add /path/to/marketplace-root

# Install plugin
/plugin install plugin-name@marketplace-name

# After changes: reinstall
/plugin uninstall plugin-name@marketplace-name
/plugin install plugin-name@marketplace-name

Plugin Patterns

Framework Plugin

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

plugins/framework-name/
├── .claude-plugin/plugin.json
├── skills/
│   └── framework-name/
│       ├── SKILL.md
│       └── references/
├── commands/
│   └── prime/
│       ├── components.md
│       └── framework.md
└── README.md

Utility Plugin

For tools and commands:

plugins/utility-name/
├── .claude-plugin/plugin.json
├── commands/
│   ├── action1.md
│   └── action2.md
└── README.md

Domain Plugin

For domain-specific knowledge:

plugins/domain-name/
├── .claude-plugin/plugin.json
├── skills/
│   └── domain-name/
│       ├── SKILL.md
│       ├── references/
│       └── scripts/
└── README.md

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:

git commit -m "feat: add new plugin"
git commit -m "fix: correct plugin manifest"
git commit -m "docs: update plugin README"
git commit -m "feat!: breaking change"

Reference Docs
