# ESLint Rule Enforcer

Automates ESLint v9 flat config enforcement across monorepos using eslint-plugin-unicorn and @typescript-eslint/parser. Scans changed files via git diff, applies auto-fixable rules, and generates per-package lint reports with violation severity breakdowns.

## Installation

Use the upstream install or setup path that matches your environment:
- npm init @eslint/config@latest
- npx eslint yourfile.js

Requirements and caveats from upstream:
- To use ESLint, you must have [Node.js](https://nodejs.org/) (^20.19.0, ^22.13.0, or >=24) installed and built with SSL support. (If you are using an official Node.js distribution, SSL is always built in.)
