Build Plugin Command

Create a new Claude Code plugin with proper manifest and structure.

Workflow

1. Invoke plugin-builder reference for current patterns:

   • Read skills/claude-code-meta/references/plugin-builder.md
   • Get: manifest structure, component organization, registration

2. Extract requirements:

   • Plugin purpose and scope
   • What components needed (skills, commands, agents, hooks)?
   • Marketplace or standalone?

3. Plan structure:

   • Determine component types
   • Plan directory layout
   • Identify dependencies

4. Create plugin directory:

   mkdir -p plugins/<plugin-name>/.claude-plugin
   

5. Write plugin.json manifest:

   {
     "name": "plugin-name",
     "version": "0.1.0",
     "description": "Clear description of what plugin does",
     "author": {
       "name": "Author Name",
       "email": "email@example.com"
     },
     "license": "MIT",
     "keywords": ["keyword1", "keyword2"]
   }
   

6. Create component directories (as needed):

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

7. Create CHANGELOG.md:

   # Changelog - Plugin Name
   
   ## [Unreleased]
   
   ## [0.1.0] - YYYY-MM-DD
   
   ### Added
   - Initial plugin with [components]
   

8. Register plugin (if marketplace):

   • Update marketplace.json
   • Update settings.json
   • Document in marketplace README

9. Validate:

   • plugin.json has all required fields
   • Version follows semver
   • CHANGELOG.md exists
   • Component directories created as needed

10. Return:

    • Plugin directory path
    • Components created
    • Registration status

Criteria

Manifest Quality:

• Clear, specific description
• Relevant keywords for discovery
• Proper semver version
• Valid author info

Structure:

• .claude-plugin/ for manifest
• Component directories only if needed
• CHANGELOG from day 1

Registration (marketplace plugins):

• Listed in marketplace.json
• Enabled in settings.json
• Documented in marketplace README
