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 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 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.
Use when auditing or improving any frontend codebase against the full Front-End Checklist rule corpus through one entry point.

Without proper dir attributes, RTL text displays incorrectly, UI elements appear backwards, and screen readers announce content in the wrong order.
dir="rtl" on for Arabic, Hebrew, Persian, Urdudir="auto" for user-generated content<bdi> for inline mixed-direction user contentVerify that this HTML document uses the appropriate dir attribute to indicate text direction for right-to-left languages like Arabic, Hebrew, or mixed content. Check user-generated inline text for dir="auto" or bidi isolation where names, handles, or snippets mix writing directions.
Add the dir attribute to the html element or specific elements with values 'ltr' (left-to-right), 'rtl' (right-to-left), or 'auto' for automatic detection. Use <bdi> or equivalent bidi isolation for mixed-direction inline content.
Explain how the dir attribute helps browsers and screen readers properly display and navigate text in different writing directions.
Review templates, server-rendered HTML, and shared components that output markup related to Set text direction for RTL languages. Flag exact elements, attributes, and routes where the rendered HTML violates the rule. Inspect user-generated inline content, not only page-level locale wrappers.
