plugin dev — Agent Skill

Plugin Development Toolkit

A comprehensive toolkit for developing Claude Code plugins with expert guidance on hooks, MCP integration, plugin structure, and marketplace publishing.

Overview

The plugin-dev toolkit provides seven specialized skills to help you build high-quality Claude Code plugins:

1. hook-development - Advanced hooks API and event-driven automation
2. mcp-integration - Model Context Protocol server integration
3. plugin-structure - Plugin organization and manifest configuration
4. plugin-settings - Configuration patterns using .claude/plugin-name.local.md files
5. command-development - Creating slash commands with frontmatter and arguments
6. agent-development - Creating autonomous agents with AI-assisted generation
7. skill-development - Creating skills with progressive disclosure and strong triggers

Each skill follows best practices with progressive disclosure: lean core documentation, detailed references, working examples, and utility scripts.

Guided Workflow Command

/plugin-dev:create-plugin

A comprehensive, end-to-end workflow command for creating plugins from scratch, similar to the feature-dev workflow.

8-Phase Process:

1. Discovery - Understand plugin purpose and requirements
2. Component Planning - Determine needed skills, commands, agents, hooks, MCP
3. Detailed Design - Specify each component and resolve ambiguities
4. Structure Creation - Set up directories and manifest
5. Component Implementation - Create each component using AI-assisted agents
6. Validation - Run plugin-validator and component-specific checks
7. Testing - Verify plugin works in Claude Code
8. Documentation - Finalize README and prepare for distribution

Features:

• Asks clarifying questions at each phase
• Loads relevant skills automatically
• Uses agent-creator for AI-assisted agent generation
• Runs validation utilities (validate-agent.sh, validate-hook-schema.sh, etc.)
• Follows plugin-dev's own proven patterns
• Guides through testing and verification
