Who is claude-code-mastery-project-starter-kit for?

Developers who already use Claude Code and want a consistent, rule-driven setup; know basic CLI, npm and git first.

What can you build with claude-code-mastery-project-starter-kit?

Scaffold a new Claude Code project with security rules and hooks already in place. Add review, commit and testing commands to an existing codebase without losing its current setup. Block commits to main and catch committed secrets automatically while Claude edits code. Watch token use, cost and rule violations of a Claude Code session in a separate terminal. Fork the template to build your own team's commands, hooks and rules and publish them as an npm package.

Claude Code works better when it has clear project rules and checks that always run. This kit supplies them ready-made: a CLAUDE.md with 11 numbered rules, slash commands for common jobs, hooks that run automatically, and skills that give Claude topic knowledge such as Docker, MongoDB or accessibility.

It is a scaffold, not an app. You install it into ~/.claude with npx, or clone it and use /new-project to generate a new project with the tooling copied in. You can also merge it into an existing project with /convert-project-to-starter-kit, which makes a safety commit first so you can undo it.

The kit supports two ways of working. In the classic way you drive with commands like /review and /commit. In the MDD way, now a separate npm package, Claude writes documentation and tests first and asks for your approval at each step.

What it does

Hooks that always run
Ten hooks block dangerous bash commands, enforce file-length limits, lint on save, protect the main branch, and check that no credentials are committed.
27 slash commands
Includes /review, /commit, /create-api, /create-e2e, /security-check, /optimize-docker, /diagram and /setup. Eleven more manage the kit itself, such as /new-project and /update-project.
25 skills
Context-aware guidance on code review, debugging, testing, API conventions, Docker, Node.js, NGINX, accessibility and web performance.
Live AI monitor
/what-is-my-ai-doing shows tool calls, tokens, cost and rule violations as they happen. The free mode needs no API key and runs with pnpm ai:monitor.
Convert existing projects
/convert-project-to-starter-kit merges the kit into a project you already have, keeping what is there, and makes a safety commit you can revert.

What you could build

Block commits to main and catch committed secrets automatically while Claude edits code.
Watch token use, cost and rule violations of a Claude Code session in a separate terminal.

Get started

Run the npx command once to install the commands, hooks and skills into ~/.claude. Then, inside Claude Code, run /new-project to create an app, cd into it, and run /setup to configure .env.

npx @claude-code-mastery/starter-kit init

/new-project my-app clean

/setup

Commands are copied from the project's README. Read it on GitHub for the full setup.
