Wookstar Claude Code Plugins

A comprehensive marketplace for Claude Code providing specialised plugins for development, documents, analytics, e-commerce, AI integrations, and individual MCP servers.

Quick Start

Add this marketplace to Claude Code:

/plugin marketplace add henkisdabro/wookstar-claude-plugins

Then install the plugins you need:

# Core development
/plugin install developer@wookstar-claude-plugins

# Document processing
/plugin install documents@wookstar-claude-plugins

# Shopify development
/plugin install shopify-developer@wookstar-claude-plugins

# Claude Code thinking tools
/plugin install claudecode@wookstar-claude-plugins

# Skill development
/plugin install ultimate-skill-creator@wookstar-claude-plugins

# Analytics (standalone)
/plugin install google-tagmanager@wookstar-claude-plugins
/plugin install google-analytics@wookstar-claude-plugins
/plugin install google-ads-scripts@wookstar-claude-plugins

# Automation skills (standalone)

/plugin install tampermonkey@wookstar-claude-plugins

/plugin install gemini@wookstar-claude-plugins
/plugin install codex@wookstar-claude-plugins

# Utilities
/plugin install timezone-tools@wookstar-claude-plugins

Or install individual MCP servers without the full toolkits:

/plugin install mcp-fetch@wookstar-claude-plugins             # Web content fetching
/plugin install mcp-google-workspace@wookstar-claude-plugins  # Gmail, Drive, Calendar
/plugin install mcp-mikrotik@wookstar-claude-plugins          # MikroTik router management
/plugin install mcp-n8n@wookstar-claude-plugins               # n8n workflow automation
/plugin install mcp-notion@wookstar-claude-plugins            # Notion integration
/plugin install mcp-open-meteo@wookstar-claude-plugins        # Weather data (no API key)
/plugin install mcp-gemini-bridge@wookstar-claude-plugins     # Google Gemini AI
/plugin install mcp-perplexity@wookstar-claude-plugins        # Perplexity AI search
/plugin install mcp-alphavantage@wookstar-claude-plugins      # Stock market data
/plugin install mcp-coingecko@wookstar-claude-plugins         # Cryptocurrency data
/plugin install mcp-currency-conversion@wookstar-claude-plugins # Currency exchange rates

Upgrading from v5.x

If you previously installed productivity, marketing, or utilities plugins:

Step 1: Uninstall Old Plugins (run in terminal, not in Claude Code)

# One-liner: Complete removal and update
claude plugin uninstall productivity@wookstar-claude-plugins && claude plugin uninstall marketing@wookstar-claude-plugins && claude plugin uninstall utilities@wookstar-claude-plugins && claude plugin marketplace update wookstar-claude-plugins && rm -rf ~/.claude/plugins/productivity ~/.claude/plugins/marketing ~/.claude/plugins/utilities

Or run each step separately:

# Uninstall old plugins
claude plugin uninstall productivity@wookstar-claude-plugins
claude plugin uninstall marketing@wookstar-claude-plugins
claude plugin uninstall utilities@wookstar-claude-plugins

# Update marketplace to get v6.0.0
claude plugin marketplace update wookstar-claude-plugins

# Remove leftover plugin folders
rm -rf ~/.claude/plugins/productivity ~/.claude/plugins/marketing ~/.claude/plugins/utilities

Step 2: Clean Up Config Files

Check these files for references to the old plugins and remove/update them:

User-level settings (~/.claude/settings.json):

# Check for old plugin references
grep -E "productivity|marketing|utilities" ~/.claude/settings.json

Look in enabledPlugins, permissions.allow, and permissions.deny arrays.

Project-level settings (.claude/settings.json in your projects):

# Find project settings with old references
find ~ -path "*/.claude/settings.json" -exec grep -l -E "productivity|marketing|utilities" {} \; 2>/dev/null

What to look for and update:

Old ReferenceReplace With
productivity@wookstar-claude-pluginsRemove or replace with specific plugins
marketing@wookstar-claude-pluginsRemove or replace with google-tagmanager, google-analytics, google-ads-scripts
utilities@wookstar-claude-pluginstimezone-tools@wookstar-claude-plugins

Step 3: Install New Plugins (in Claude Code or terminal)

/plugin install timezone-tools@wookstar-claude-plugins        # replaces utilities
/plugin install google-apps-script@wookstar-claude-plugins    # was in productivity
/plugin install tampermonkey@wookstar-claude-plugins          # was in productivity
/plugin install git-worktrees@wookstar-claude-plugins         # was productivity commands
/plugin install google-tagmanager@wookstar-claude-plugins     # was in marketing
/plugin install google-analytics@wookstar-claude-plugins      # was in marketing
/plugin install google-ads-scripts@wookstar-claude-plugins    # was in marketing
/plugin install gemini@wookstar-claude-plugins   # new
