Developer Kit for Claude Code

A modular plugin system of reusable skills, agents, and commands for automating development tasks in Claude Code

Listed on:

• context7 — Skills marketplace
• skills.sh — AI skills directory

Developer Kit for Claude Code teaches Claude how to perform development tasks in a repeatable way across multiple languages and frameworks. Built as a modular marketplace, you can install only the plugins you need.

Quick Start

# Install from marketplace (recommended)
/plugin marketplace add giuseppe-trisciuoglio/developer-kit

# Or install from local directory
/plugin install /path/to/developer-kit

Architecture

Developer Kit is organized as a modular marketplace with 11 independent plugins:

plugins/
├── developer-kit-core/            # Core agents/commands/skills (required)
├── developer-kit-java/            # Java/Spring Boot/LangChain4J/AWS SDK/GraalVM Native Image
├── developer-kit-typescript/      # NestJS/React/React Native/Next.js/Drizzle/Monorepo
├── developer-kit-python/          # Python development/AWS Lambda
├── developer-kit-php/             # PHP/WordPress/AWS Lambda
├── developer-kit-aws/             # AWS CloudFormation/AWS Architecture
├── developer-kit-ai/              # Prompt Engineering/RAG/Chunking
├── developer-kit-devops/          # Docker/GitHub Actions
├── developer-kit-project-management/  # LRA workflow/Meetings
├── developer-kit-tools/           # Additional development tools and MCP integrations
└── github-spec-kit/               # GitHub specification integration

Current marketplace totals: 116 skills, 43 agents, and 44 commands across the 11 plugin manifests.

Language plugins (Java, TypeScript, Python, PHP) include coding rules (rules/ directory) that auto-activate via globs: path-scoped matching to enforce naming conventions, project structure, language best practices, and error handling patterns. They also include LSP server configurations (.lsp.json) for real-time code intelligence, diagnostics, and navigation features.

Workflow

The Developer Kit follows a systematic development workflow that ensures high-quality, well-documented features from idea to implementation:

1. Brainstorming Phase

Command: /devkit.brainstorm [idea-description]

Start here when you have a new feature idea. This command guides you to create a functional specification (WHAT the system should do, not HOW):

• Idea Refinement: Deep exploration through structured dialogue
• Use Case Definition: Define user behaviors and business rules
• Acceptance Criteria: Establish testable conditions for completion
• Specification Review: Validate with user

Output: Functional specification saved to docs/specs/YYYY-MM-DD--feature-name.md

Example:

/devkit.brainstorm Add user authentication with JWT tokens

Next step: After specification, continue with /devkit.spec-to-tasks

2. Specification to Tasks Phase

Command: /devkit.spec-to-tasks [--lang=java|spring|typescript|nestjs|react|python|general] [spec-file]

Converts the functional specification into atomic, executable tasks:

• Task Decomposition: Break down specification into actionable tasks
• Dependency Mapping: Identify task dependencies
• Acceptance Criteria: Each task has clear completion criteria
• Implementation Commands: Pre-filled commands for execution
• Complexity Scoring: Automatic calculation of task complexity (0-100+ scale)
• Strong Constraint: Tasks with score ≥ 51 MUST be split before implementation

Output: Task list saved to docs/specs/[id]/tasks/TASK-XXX.md with complexity scores

Example:

/devkit.spec-to-tasks docs/specs/001-user-auth/
/devkit.spec-to-tasks --lang=spring docs/specs/001-user-auth/

Next step: Review task complexity and manage tasks with /devkit.task-manage

2.5. Task Management Phase (NEW)

Command: /devkit.task-manage --action=[list|split|add|mark-optional|update|regenerate-index] [options]

Manage tasks after generation to ensure they're appropriately sized and prioritized:
