+# Project Init Plugin
+
+Initialize new projects with a single command. Creates a directory, initializes git, and sets up Claude Code configuration.
+
+## Commands
+
+### `/new-project <project-name>`
+
+Creates a new project directory with:
+- Git repository initialized
+- `CLAUDE.md` template for project context
+- `.gitignore` with common defaults
+- Initial commit
+
+**Usage:**
+```bash
+/new-project my-awesome-app
+```
+
+**What it creates:**
+```
+my-awesome-app/
+├── .git/
+├── .gitignore
+└── CLAUDE.md
+```
+
+## Installation
+
+This plugin is included in the Claude Code plugins directory. To use it:
+
+1. Ensure Claude Code is installed
+2. The plugin is automatically available when running Claude Code from the repository
+3. Or install via the plugin marketplace
+
+## Why Use This?
+
+This plugin streamlines the project creation workflow. Instead of:
+```bash
+mkdir my-project
+cd my-project
+git init
+# manually create CLAUDE.md
+# manually create .gitignore
+git add -A
+git commit -m "Initial commit"
+```
+
+Just run:
+```bash
+/new-project my-project
+```
+
+## Feature Request
+
+This plugin serves as a workaround until native support is added to the Claude Code CLI. See the feature request: [Add project name argument to init command](https://github.com/anthropics/claude-code/issues/18024)

+---
+
+## Your Task
+
+Create a new project directory and initialize it for development with Claude Code.
+
+**Project name from arguments:** $ARGUMENTS
+
+## Workflow
+
+### 1. Validate Project Name
+
+If no project name was provided (`$ARGUMENTS` is empty), ask the user:
+- "What would you like to name your project?"
+
+Validate the project name:
+- Must not be empty
+- Should be a valid directory name (no special characters that would cause issues)
+- Should not already exist as a directory
+
+### 2. Create Project Structure
+
+Execute these steps:
+
+1. **Create the project directory:**
+   ```bash
+   mkdir -p <project-name>
+   ```
+
+2. **Initialize git repository:**
+   ```bash
+   cd <project-name> && git init
+   ```
+
+3. **Create CLAUDE.md with basic structure:**
+   Create a `CLAUDE.md` file in the new directory with:
+   ```markdown
+   # <Project Name>
+
+   ## Overview
+   [Brief description of what this project does]
+
+   ## Tech Stack
+   [List technologies, frameworks, languages used]
+
+   ## Project Structure
+   [Describe the directory layout once established]
+
+   ## Development Guidelines
+   [Any coding standards, patterns, or practices to follow]
+
+   ## Getting Started
+   [How to set up and run the project]
+   ```
+
+4. **Create .gitignore with common defaults:**
+   ```
+   # Dependencies
+   node_modules/
+   venv/
+   __pycache__/
+
+   # Environment
+   .env
+   .env.local
+
+   # IDE
+   .idea/
+   .vscode/
+   *.swp
+
+   # OS
+   .DS_Store
+   Thumbs.db
+
+   # Build
+   dist/
+   build/
+   *.egg-info/
+   ```
+
+5. **Create initial commit:**
+   ```bash
+   cd <project-name> && git add -A && git commit -m "Initial commit: project scaffolding"
+   ```
+
+### 3. Report Success
+
+After creating the project, inform the user:
+
+1. What was created:
+   - Directory: `<project-name>/`
+   - Git repository initialized
+   - `CLAUDE.md` created
+   - `.gitignore` created
+   - Initial commit made
+
+2. Next steps:
+   - `cd <project-name>` to enter the project
+   - Run `claude` to start working with Claude Code
+   - Edit `CLAUDE.md` to add project-specific context
+
+## Important Notes
+
+- Create all files in the NEW directory, not the current directory
+- Use the exact project name provided (preserve casing)
+- Do not create unnecessary files beyond what's specified
+- If the directory already exists, ask the user how to proceed (overwrite, use different name, or cancel)
