My Claude Code Plugins 🚀

Personal collection of workflow plugins I've built for Claude Code

Hey! I'm sharing some plugins I've created to make development with Claude Code more systematic and powerful. These are based on advanced context engineering patterns that help with with my daily work.

🎯 Featured Plugins

[Research-Plan-Implement](./plugins/research-plan-implement)

**The ultimate workflow plugin for systematic software development**

A three-phase methodology that helps you:

• 🔍 Research - Deep codebase analysis with specialized AI agents
• 📋 Plan - Interactive implementation planning driven by real code patterns
• ⚡ Implement - Structured execution with automated verification

Based on [Advanced Context Engineering](https://github.com/humanlayer/advanced-context-engineering-for-coding-agents/blob/main/ace-fca.md) by [Dexter Horthy](https://github.com/humanlayer) @ HumanLayer.

**What you get:**

• 4 specialized research agents (codebase analyzer, locator, pattern finder, web researcher)
• 3 workflow commands mapping to Research → Plan → Implement
• Documentation-first philosophy: understand what IS, not what SHOULD BE
• Task organization system with metadata tracking

[Spec-Driven Development](./plugins/spec-driven-development)

**Specification-first development workflow for building projects right the first time**

A four-phase methodology that guides you through:

• 📝 Clarify Requirements - Interactive questioning to capture clear, testable requirements
• 🏗️ Clarify Design - Technical design and architecture based on requirements
• 📋 Create Plan - Detailed task breakdown with verification steps
• ⚡ Implement Plan - Systematic implementation with rigorous testing

**What you get:**

• 4 workflow commands mapping to Requirements → Design → Plan → Implement
• Specification documents (requirements.md, design.md, plan.md) that drive development
• Mand
