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. Specifications-Driven Development (SDD)

Transform ideas into production-ready code through a structured workflow:

Phase 1: Specification Creation

Command	When to Use	Output
/specs:brainstorm	New features, complex requirements	Full specification with 9 phases
/specs:quick-spec	Bug fixes, small enhancements	Lightweight 4-phase spec

The specification lives in docs/specs/[id]/YYYY-MM-DD--feature-name.md

Phase 2: Task Generation

Command	Description
/specs:spec-to-tasks	Convert specification into executable task files
/specs:task-manage	Add, split, update, or reorganize tasks

Tasks are generated in docs/specs/[id]/tasks/ with individual task files.

Phase 3: Implementation

Command	Description
/specs:task-implementation	Guided implementation of a specific task
/specs:task-tdd	Test-Driven Development approach for the task

Each task implementation updates the Knowledge Graph for context preservation.

Phase 4: Quality Assurance

Command	Description
/specs:task-review	Verify task meets specifications and code quality standards
/specs:code-cleanup	Professional cleanup: remove debug logs, optimize imports
/specs:spec-sync-with-code	Synchronize spec with actual implementation

Additional Workflow Commands

Command	Description
/specs:spec-quality-check	Interactive quality assessment of specifications
/specs:spec-sync-context	Sync Knowledge Graph, Tasks, and Codebase state
/specs:ralph-loop	Automated loop for spec-driven development
/devkit.refactor	Refactor existing code with architectural analysis
/devkit.github.create-pr	Create PR with comprehensive description

4. Rules

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

# Auto-activates for *.java files
globs: ["**/*.java"]
---
Always use constructor injection. Never use field injection with @Autowired.

📋 Note on Rules Installation

Plugins do not automatically install rules into your project. To use the rules, you can copy them manually
or use the Makefile command:

# Copy rules from a specific plugin
make copy-rules PLUGIN=developer-kit-java

# Or manually copy .md files from the plugin's rules/ folder
mkdir -p .claude/rules
cp plugins/developer-kit-[language]/rules/*.md .claude/rules/

The rules will be automatically activated based on the globs: patterns defined in the header of each file.
