Set up ESLint, a tool that checks JavaScript for errors and coding rule violations. Configure shared rules, connect checks to editors and automated workflows, and review flagged code alongside its behavior in the browser.
Use when reviewing scripts, client components, bundles, or runtime behavior related to Lint JavaScript code. Inspect both source code and the browser execution path so fixes target the real bottleneck or bug.
Review the instructions the agent will receive before you install.
Linting catches bugs before runtime, enforces team coding standards, and prevents common mistakes that slip through code review.
pnpm dlx eslint --initSet up JavaScript linting tools like ESLint to automatically detect syntax errors, enforce coding standards, and maintain consistent code quality across the team.
Configure ESLint with appropriate rules and plugins, integrate it into your development workflow, and fix all linting errors and warnings.
Explain how JavaScript linting prevents bugs, enforces consistent coding standards, improves code readability, and catches potential issues before runtime.
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.

Create and review custom 404 pages that help visitors recover from broken or moved links through search and navigation. Check the rendered page and HTTP response so missing content returns a proper 404 status.
Audit or create a dedicated About page that explains a website’s purpose and identifies its people or organization. Review the rendered output and supporting information, including expertise and contact details, to find gaps.
Review and add automated accessibility checks for components, pages, and continuous integration workflows. Use axe-based tools to detect structural and attribute issues, while identifying checks that still need keyboard or screen reader testing.
Review sign-in, registration, multi-factor authentication, and account recovery for accessibility barriers. Find blocked paste, difficult code entry, and inaccessible backup methods, then suggest authentication paths that support password managers, autofill, or device approval.
Review form errors, success messages, and live updates so screen reader users receive important notifications. Check the HTML delivered to the browser, announcement settings, display duration, and dismissal controls, then identify specific elements that need changes.
Review HTML tables so screen reader users can understand how headers and data relate. Check header markup, table descriptions, and merged cells, then identify specific fixes and ways to verify them.
