Front-End-Checklist

Use when reviewing rendered HTML, interactive components, or design-system patterns related to Make modal dialogs keyboard accessible. Check native semantics first, then inspect keyboard behavior, focus flow, accessible names, and screen-reader output where relevant.

Use when reviewing CI coverage, automated checks, or test strategy related to Follow mocking best practices. Focus on whether the rule is continuously verified, not just documented.

Use when reviewing CI coverage, automated checks, or test strategy related to Test on real mobile devices and viewports. Focus on whether the rule is continuously verified, not just documented.

Use when reviewing an HTTPS page for resources (scripts, images, stylesheets, iframes) that are loaded over plain HTTP.

Use when auditing server configuration or diagnosing broken resources. Applies to any web server serving HTML, CSS, JS, images, fonts, or other static assets.

Use when auditing page metadata or generating SEO-optimized titles. Applies to every HTML page that should appear in search results.

Use when reviewing rendered HTML, interactive components, or design-system patterns related to Avoid meta refresh redirects. Check native semantics first, then inspect keyboard behavior, focus flow, accessible names, and screen-reader output where relevant.

Use when auditing HTML document structure. Applies to any page where meta tags (noindex, canonical-url, description, viewport, OG tags) may have been injected into the body by CMS plugins, widgets, or JavaScript rendering.

Use when auditing page metadata or generating descriptions for new pages. Applies to every page that should receive organic search traffic.

Use when reviewing scripts, client components, bundles, or runtime behavior related to Prevent common memory leak patterns. Inspect both source code and the browser execution path so fixes target the real bottleneck or bug.

Use when auditing URL structure or configuring a new site's routing. Applies to any server or framework that allows case-insensitive file systems (Linux servers are case-sensitive by default).

Use when reviewing stylesheets, component styles, and responsive behavior related to Use CSS logical properties for i18n and RTL support. Check the rendered layout across breakpoints and interaction states before proposing a fix.

Use when reviewing image assets, icon libraries, or components that render illustrations to identify culture-specific content that may need locale overrides or replacement with neutral alternatives.

Use when auditing a local business website's structured data. Applies to any business that serves customers at a physical location or specific geographic area.

Use when auditing slow page loads, heavy assets, or rendering delays related to Show loading indicators. Verify the actual bottleneck in DevTools, Lighthouse, or field data before recommending changes.

Use when auditing public documentation portals, API references, help centers, SDK docs, or large knowledge bases. Check the final file served at `/llms.txt` and verify that the linked pages are stable, high-value, and accessible without relying on a JavaScript-only interface.

Use when auditing content pages for AI discoverability. Applies to any informational page intended to appear in AI-generated answers, search snippets, or knowledge base extraction.

Use when applies to HTML documents with `<li>` elements. Also applies to custom ARIA lists where `role='listitem'` must be owned by `role='list'`. Common violations occur in templating systems where list markup is split across components or in CSS resets where developers use `<li>` for layout without proper list parents.

Use when reviewing dashboards, admin tables, search results, or feeds with many repeated items. Confirm the bottleneck is DOM or rendering cost before introducing virtualization because small lists usually do not need the added complexity.

Use when reviewing rendered HTML, interactive components, or design-system patterns related to Use correct list structure. Check native semantics first, then inspect keyboard behavior, focus flow, accessible names, and screen-reader output where relevant.

Use when reviewing rendered HTML, interactive components, or design-system patterns related to Use descriptive link text. Check native semantics first, then inspect keyboard behavior, focus flow, accessible names, and screen-reader output where relevant.

Use when applies to hyperlinks (`<a>` elements) that appear inline within paragraphs or text blocks. Does not apply to navigation menus, button-style links, or standalone links that are visually isolated from body text. Use when reviewing CSS that removes text-decoration from inline body copy links.

Use when reviewing templates, rendered HTML, or shared components related to Check for broken links. Validate the final browser-facing markup, not just the source framework abstraction.

Use when generating URL slugs from article titles, auditing URL structures for unnecessary depth or length, or reviewing URL patterns in a CMS or router configuration.

Use when auditing slow page loads, heavy assets, or rendering delays related to Avoid serving legacy JavaScript to modern browsers. Verify the actual bottleneck in DevTools, Lighthouse, or field data before recommending changes.
