Creating a New Plugin

1. Create directory structure

bash

mkdir -p plugins/<plugin-name>/.claude-plugin
mkdir -p plugins/<plugin-name>/skills
mkdir -p plugins/<plugin-name>/agents
mkdir -p plugins/<plugin-name>/commands

2. Create plugin.json

json

{
  "name": "<plugin-name>",
  "version": "1.0.0",
  "description": "<Brief description>",
  "author": {
    "name": "hanibalsk",
    "url": "https://github.com/hanibalsk"
  },
  "repository": "https://github.com/hanibalsk/claude-marketplace",
  "license": "MIT",
  "keywords": ["keyword1", "keyword2"]
}

3. Create CLAUDE.md

Document the plugin with:

•Overview description
•Skills table (if any)
•Agents table (if any)
•Commands table (if any)
•Usage examples

4. Add to marketplace.json

Add entry to .claude-plugin/marketplace.json plugins array:

json

{
  "name": "<plugin-name>",
  "version": "1.0.0",
  "description": "<Brief description>",
  "source": "./plugins/<plugin-name>",
  "author": {
    "name": "hanibalsk",
    "url": "https://github.com/hanibalsk"
  },
  "keywords": ["keyword1", "keyword2"]
}

Adding Skills

---

# Skill Title

After adding skills

Adding Agents

Version Management

Bump version script

bash

# Explicit version
./scripts/bump-version.sh <plugin-name> 1.2.0

# Increment types
./scripts/bump-version.sh <plugin-name> patch  # 1.1.0 → 1.1.1
./scripts/bump-version.sh <plugin-name> minor  # 1.1.0 → 1.2.0
./scripts/bump-version.sh <plugin-name> major  # 1.1.0 → 2.0.0
