Use when reviewing templates, rendered HTML, or shared components related to Implement accessible breadcrumb navigation. Validate the final browser-facing markup, not just the source framework abstraction.
Use when auditing metadata, crawlability, structured data, or indexability related to Implement valid BreadcrumbList schema. Verify the rendered HTML and HTTP response rather than relying only on source files.
Use when reviewing templates, rendered HTML, or shared components related to Declare UTF-8 character encoding. Validate the final browser-facing markup, not just the source framework abstraction.
Use when reviewing templates, rendered HTML, or shared components related to Set text direction for RTL languages. Validate the final browser-facing markup, not just the source framework abstraction.
Use when auditing a site's meta tag uniqueness, generating page-specific meta descriptions, or reviewing CMS templates that inject the same description globally.
Use when you need to find the 2-3 most popular and well-maintained npm packages relevant to a frontend checklist rule, validate they meet quality thresholds, and add them to the rule's frontmatter.

When a navigation link's URL matches a tracking domain pattern, the adblocker may block the request entirely — the user clicks the link and nothing happens, breaking core site functionality.
Identify external script sources, image src URLs, iframe src URLs, and anchor href values that point to known tracking domains (googletagmanager.com, hotjar.com, facebook.net, doubleclick.net, etc.). Test whether these resources load successfully with uBlock Origin enabled.
Self-host critical external scripts on your own domain. Use a reverse proxy or server-side route to forward requests to third-party analytics APIs. For navigation links, avoid using tracking redirect URLs — use direct destination URLs with UTM parameters appended instead.
Explain how domain-level adblocker filter lists work, which domains are commonly blocked, how blocked resources affect site functionality and analytics accuracy, and the self-hosting approach to bypass domain blocks.
Review server config, headers, forms, and integration points related to Blocked Tracking Links. Flag exact responses, cookies, or browser behaviors that violate the rule, and verify them against the effective production-like response.
