Marketplace Manager

Marketplace Manager

Purpose

Automatically manages the claude-code-plugins marketplace catalog system, handling updates to marketplace.extended.json, syncing to marketplace.json, and ensuring catalog integrity.

Trigger Keywords

• "update marketplace"
• "sync marketplace" or "sync catalog"
• "add to marketplace"
• "marketplace catalog"
• "update catalog"
• "regenerate marketplace"

Two-Catalog System

Critical Understanding:

marketplace.extended.json (SOURCE OF TRUTH)
├── Full metadata
├── Extended fields (featured, mcpTools, etc.)
└── Edit THIS file manually

↓ npm run sync-marketplace

marketplace.json (GENERATED)
├── CLI-compatible subset
├── Sanitized fields
└── NEVER edit directly

Marketplace Management Tasks

1. Add Plugin to Catalog

When adding new plugin:

// Add to marketplace.extended.json
{
  "name": "plugin-name",
  "source": "./plugins/category/plugin-name",
  "description": "Clear one-line description",
  "version": "1.0.0",
  "category": "productivity",
  "keywords": ["keyword1", "keyword2"],
  "author": {
    "name": "Author Name",
    "email": "[email protected]"
  },
  "repository": "https://github.com/user/repo",
  "featured": false  // true for featured plugins
}

Then:

npm run sync-marketplace

2. Update Plugin Version

When bumping version:

1. Update plugins/category/plugin-name/.claude-plugin/plugin.json
2. Update marketplace.extended.json entry
3. Run npm run sync-marketplace
4. Validate sync worked: git diff .claude-plugin/marketplace.json

3. Sync Validation

After sync, verify:

# Check marketplace.json was regenerated
git status .claude-plugin/marketplace.json

# Validate JSON syntax
jq empty .claude-plugin/marketplace.extended.json
jq empty .claude-plugin/marketplace.json

# Check specific plugin entry
jq '.plugins[] | select(.name == "plugin-name")' .claude-plugin/marketplace.json

4. Featured Plugin Management

Mark plugin as featured:

{
  "name": "plugin-name",
  "featured": true,  // Add this field
  // ... rest of fields
}

Featured plugins appear first in marketplace.

5. Catalog Integrity Checks

I automatically verify:

• ✅ No duplicate plugin names
• ✅ All source paths exist
• ✅ All plugins have required fields
• ✅ Versions are semantic (x.y.z)
• ✅ Categories are valid
• ✅ JSON is valid
• ✅ Sync is current (no uncommitted changes to marketplace.json)

Valid Categories

productivity, security, testing, deployment, documentation,
analysis, integration, ai, devops, debugging, code-quality,
design, example, api-development, database, crypto,
performance, ai-ml, other

Sync Process

When I sync marketplace:

1. Backup Current State

   cp .claude-plugin/marketplace.json .claude-plugin/marketplace.json.backup
   

2. Run Sync Script

   npm run sync-marketplace
   # or: node scripts/sync-marketplace.cjs
   

3. Validate Output

   # Check sync success
   jq empty .claude-plugin/marketplace.json
   
   # Verify plugins count
   jq '.plugins | length' .claude-plugin/marketplace.json
   

4. Check Diff

   git diff .claude-plugin/marketplace.json
   

5. Commit if Valid

   git add .claude-plugin/marketplace.extended.json .claude-plugin/marketplace.json
   git commit -m "chore: Update marketplace catalog"
   

Sanitized Fields

These fields are REMOVED from marketplace.json (CLI):

• featured - Extended metadata
• mcpTools - Extended metadata
• pluginCount - Extended metadata
• pricing - Extended metadata
• components - Extended metadata

Only add these to marketplace.extended.json

Marketplace Schema

Required fields for every plugin:

{
  "name": "string (kebab-case)",
  "source": "string (relative path from repo root)",
  "description": "string (clear, concise)",
  "version": "string (semver: x.y.z)",
  "category": "string (from valid list)",
  "keywords": "array (at least 2)",
  "author": {
    "name": "string",
    "email": "string (valid email)"
  }
}

Optional fields:

{
  "repository": "string (GitHub URL)",
  "homepage": "string (docs URL)",
  "license": "string (MIT, Apache-2.0, etc.)",
  "featured": "boolean (extended only)",
  "mcpTools": "number (extended only)"
}
