Lint JavaScript code
SkillWeb & browsingjavascript-linter is a skill for AI agents that guides them through linting JavaScript code with ESLint. It covers setting up linting, applying shared configs, and reviewing scripts, client components, and bundles so fixes target the real bug rather than a symptom.
Available today. Use it from your connected AI after setup.
No other account needed.
Have a JavaScript project with ESLint available as your linting tool.
Then ask your AI: use the Lint JavaScript code skill
What your AI can do with it
- Set up ESLint using pnpm dlx eslint --init
- Apply shared configs such as eslint:recommended and @typescript-eslint
- Detect syntax errors and enforce team coding standards automatically
- Review scripts, client components, and browser execution paths for rule violations
- Flag imports, event handlers, runtime side effects, and blocking operations
- Explain how linting prevents bugs and improves code readability
Getting started
- Have a JavaScript project with ESLint available as your linting tool.
- Add the javascript-linter skill to your agent's skills so it can be triggered when reviewing scripts.
- Ask the agent to review a script, client component, or bundle related to linting.
- Follow the agent's guidance to configure ESLint rules and plugins and fix reported errors and warnings.
- Add lint checks to your CI/CD pipeline so issues are caught before runtime.
What this skill tells your AI
The instructions your AI receives, as published by thedaviddias/front-end-checklist in skills/javascript-linter/SKILL.md and read by ahel’s review.
Linting catches bugs before runtime, enforces team coding standards, and prevents common mistakes that slip through code review.
Quick Reference
- Set up ESLint with
pnpm dlx eslint --init - Use shared configs (eslint:recommended, @typescript-eslint)
- Integrate with your editor for real-time feedback
- Add lint checks to CI/CD pipeline
Check
Set up JavaScript linting tools like ESLint to automatically detect syntax errors, enforce coding standards, and maintain consistent code quality across the team.
Fix
Configure ESLint with appropriate rules and plugins, integrate it into your development workflow, and fix all linting errors and warnings.
Explain
Explain how JavaScript linting prevents bugs, enforces consistent coding standards, improves code readability, and catches potential issues before runtime.
Code Review
Review scripts, client components, and browser execution paths related to Lint JavaScript code. Flag exact imports, event handlers, runtime side effects, or blocking operations that violate the rule, and state how the change should be verified in the browser.
