agentskillexchange ESLint Rule Analyzer
Analyzes ESLint configurations using the ESLint Node.js API (new ESLint().calculateConfigForFile) and flat config system. Detects rule conflicts, unused rules, and generates project-specific rule recommendations from eslint-plugin-unicorn and typescript-eslint.
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 (^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.)
- node-linker=hoisted
Which Node.js versions does ESLint support?
Basic usage or getting-started notes:
If you use ESLint's TypeScript type definitions, TypeScript 5.3 or later is required.
