AI Coding Project Boilerplate: A Starter Kit for Claude Code

*Read this in other languages: 日本語 | 简体中文*

Set up a TypeScript repository for development with Claude Code. create-ai-project adds a project-level CLAUDE.md, ready-to-use commands, specialized agents, and skills so Claude can follow your repository's rules while working on changes.

Use this starter kit to create a new project and keep its Claude Code setup up to date. You get a working development environment without assembling prompts and agent definitions yourself. Your team can version, share, and adapt that environment alongside the code.

What you can start with

- Develop with TypeScript, Biome formatting and linting, and Vitest already configured
- Record project context and quality standards for later sessions and other contributors
- Turn team knowledge into skills Claude can use when the work calls for them

Quick start

Requires Node.js 26.12.1+, pnpm, and Claude Code.

Start a new project

Add --lang=ja or --lang=zh-CN to the first command to use Japanese or Simplified Chinese workflow instructions.

Run your first change

Once Claude Code is running:

/project-inject sets up the initial project context.

/implement clarifies the request and inspects the existing code. Straightforward changes can proceed without design documents. When design decisions are needed, it prepares a design and plan for your approval before implementation. It then runs the applicable checks and reviews larger changes.

See the Quick Start Guide for the full setup and first-run walkthrough.

Choose a workflow

Design now, implement later

The design command stops for approval. You can continue planning and implementation later, in a new session or with another contributor, using the approved documents. The plan records…
