Runs ESLint for JavaScript and TypeScript code quality enforcement, static analysis, and automated fixing.
The ESLint Checker skill enables Claude Code to perform professional-grade static analysis and style enforcement across JavaScript and TypeScript projects. It handles the entire ESLint lifecycle—from verifying the local environment and configuration files to executing linting runs and generating detailed health reports. Designed with agentic safety in mind, it includes a recovery protocol for parsing errors and requires user confirmation before applying auto-fixes, ensuring your codebase remains stable while adhering to project-specific coding standards and best practices.
