# ESLint Config Generator

Every team argues about eslint rules. This tool reads your actual code and generates a config that matches how you already write.

**One command. Zero config. Just works.**

## Quick Start

```bash
npx ai-eslint-config
```

## What It Does

- Analyzes your existing code style
- Generates ESLint config matching those patterns
- Supports flat config and legacy formats
- No more arguing about semicolons

## Usage Examples

```bash
# Generate eslint.config.js
npx ai-eslint-config

# Legacy .eslintrc.json format
npx ai-eslint-config --format json

# Analyze specific directory
npx ai-eslint-config --dir ./src
```

## Best Practices

- **Run on representative code** - not just one file
- **Review the rules** - might catch some bad habits too
- **Add prettier if needed** - don't mix formatting with linting
- **Commit the config** - everyone uses the same rules

## When to Use This

- Starting a new project and need eslint setup
- Inheriting a project with no linting
- Want to codify existing code style
- Migrating to flat config format

## How It Works

Reads sample files from your codebase, identifies patterns like semicolon usage, quote style, and indentation. Then generates an ESLint config that enforces those patterns.
