Why Developer Kit?

Developer Kit is a modular plugin marketplace for Claude Code that teaches Claude how to perform development tasks in a repeatable, high-quality way. Instead of generic AI responses, you get domain-specific expertise for your exact tech stack.

• 🧩 Modular by Design — Install only what you need. Java developer? Grab developer-kit-java. Full-stack TypeScript? Add developer-kit-typescript.
• 🎯 Domain Experts — 45+ specialized agents for code review, refactoring, security audits, architecture design, and testing across 7+ languages.
• 📚 150+ Skills — Reusable capabilities from Spring Boot CRUD generation to CloudFormation templates, all with best practices built-in.
• 🔄 Multi-CLI Support — Works with Claude Code, GitHub Copilot CLI, OpenCode CLI, and Codex CLI.
• ⚡ Auto-Activation — Path-scoped rules automatically activate when you open relevant files. No configuration needed.

Usage

Developer Kit provides four layers of capabilities:

1. Skills

Reusable capabilities loaded on-demand. Example:

[Skill: spring-boot-crud-patterns activated]

Skills automatically provide patterns, templates, and best practices for specific tasks.

2. Agents

Specialized sub-agents for complex workflows:

# Invoke via natural language
"Review this code as a Spring Boot expert"

# Or use commands
/devkit.java.code-review
/devkit.typescript.code-review

3. Rules

Path-scoped rules auto-activate based on file patterns:

# Auto-activates for *.java files
globs: ["**/*.java"]
