Dev Utils Marketplace offers 15 focused plugins for Claude Code that can be installed independently per repository. Now in v3.0, each plugin is split into granular component packages - install only commands, agents, or hooks as needed.

Key Features:

• NEW: Granular component packages (commands, agents, hooks separately)
• Modular architecture - install only what you need
• 15 specialized plugins → 46 component packages
• 37+ commands, 61+ agents, and 21+ automation hooks
• Repository-specific customization
• Team-friendly configuration

Project Status: Production Ready (v3.0.0)

What's New in v3.0

🎯 Granular Component Packages

Each plugin is now split into component-specific packages:

• {plugin}-commands - Slash commands only
• {plugin}-agents - AI agents only
• {plugin}-hooks - Automation hooks only

Example:

# v2.0 (All-in-one)
/plugin install core-essentials@dev-utils-marketplace  # 8 commands + 4 agents + 5 hooks

# v3.0 (Granular - Choose what you need)
/plugin install core-essentials-commands@dev-utils-marketplace  # Just 8 commands
/plugin install core-essentials-agents@dev-utils-marketplace    # Just 4 agents
/plugin install core-essentials-hooks@dev-utils-marketplace     # Just 5 hooks

Benefits:

• ✅ Lighter footprint - Install commands without agent overhead
• ✅ Faster performance - Less code loaded in Claude Code
• ✅ Clearer dependencies - Explicit about what you use
• ✅ Flexible combinations - Mix components from different plugins
• ✅ Independent updates - Update one component without affecting others

Migration: See Migration Guide for upgrade instructions.

Backward Compatibility: v2.0-style meta-packages still work but are deprecated (will be removed in v4.0.0).

Philosophy

Granular > Modular > Monolithic

We believe in maximum flexibility - install exactly what you need:

v1.0: All-or-nothing monolithic plugin v2.0: Modular plugins (commands + agents + hooks bundled) v3.0: Granular components (commands, agents, hooks separate)

Build your perfect development environment:

• Install only commands for interactive workflows
• Add agents for AI-powered assistance
• Enable hooks for automation
• Mix and match components across plugins

Example Evolution:

# v1.0 - All or nothing
/plugin install dev-utils-plugin@dev-utils-marketplace  # Everything

# v2.0 - Modular plugins
/plugin install core-essentials@dev-utils-marketplace   # 8 commands + 4 agents + 5 hooks

# v3.0 - Granular components (NEW!)
/plugin install core-essentials-commands@dev-utils-marketplace  # Just 8 commands
/plugin install core-essentials-agents@dev-utils-marketplace    # Add 4 agents later
# No hooks needed? Don't install them!
