What happens if my ESLint configuration is missing?

The skill performs a grounding check before execution. If no configuration file is found, it will alert you rather than running with incorrect defaults.

Does this skill support TypeScript?

Yes, it is fully optimized for both JavaScript and TypeScript, supporting specific extensions and TypeScript-ESLint parsers.

Will it automatically change my code without permission?

No. The skill includes a mandatory verification step and uncertainty escalation, requiring user confirmation before applying auto-fixes to production code.

Can I see a preview of fixes before they are applied?

Yes, the skill supports a dry-run mode that allows you to preview proposed changes via a diff before committing them to the file system.

Does it handle conflicts with Prettier?

The skill includes logic to detect potential conflicts with Prettier and will escalate to the user for clarification rather than making contradictory changes.

Developer Tools

Runs ESLint for JavaScript and TypeScript code quality enforcement, static analysis, and automated fixing.

About

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.

Key Features

Safe auto-fixing with dry-run previews and user confirmation prompts
67 GitHub stars
Smart recovery protocols for handling parsing errors and missing plugins
Automated static analysis for JavaScript and TypeScript codebases
Detailed reporting including rule-based error counts and HTML output
Environment grounding to verify Node.js, ESLint, and configuration integrity

Use Cases

Enforcing consistent coding standards across large TypeScript repositories
Automating code style cleanup before submitting pull requests
Identifying syntax errors and anti-patterns during active development cycles
