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:

Component	Location	Format
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:

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

Detailed documentation included:

Reference	Content
`references/plugin-structure.md`	Directory structure, manifest schema, components
`references/marketplace-schema.md`	Marketplace format, plugin entries, distribution
`references/workflows.md`	Step-by-step workflows, patterns, publishing

Scripts

Script	Purpose
`scripts/create_plugin.py`	Scaffold new plugin
`scripts/bump_version.py`	Update versions

How to use this skill

Install plugin-forge by running npx skills add cachemoney/agent-toolkit --skill plugin-forge in your project directory. Run the install command above in your project directory. The skill file will be downloaded from GitHub and placed in your project.

No configuration needed. Your AI agent (Claude Code, Cursor, Windsurf, etc.) automatically detects installed skills and uses them as context when generating code.

The skill enhances your agent's understanding of plugin-forge, helping it follow established patterns, avoid common mistakes, and produce production-ready output.

What you get

Skills are plain-text instruction files — not executable code. They encode expert knowledge about frameworks, languages, or tools that your AI agent reads to improve its output. This means zero runtime overhead, no dependency conflicts, and full transparency: you can read and review every instruction before installing.

Compatibility

This skill works with any AI coding agent that supports the skills.sh format, including Claude Code (Anthropic), Cursor, Windsurf, Cline, Aider, and other tools that read project-level context files. Skills are framework-agnostic at the transport level — the content inside determines which language or framework it applies to.

Data sourced from the skills.sh registry and GitHub. Install counts and security audits are updated regularly.
