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.

Duplicate IDs on active elements can cause browsers and assistive technologies to skip items, misdirect focus, or fail to trigger the correct action.
Search for duplicate id attributes on focusable or active HTML elements.
Assign a unique id to each active element to ensure correct focus handling and accessibility.
Explain how unique IDs on active elements prevent navigation errors for keyboard and screen reader users.
Review the rendered markup and interactive states that affect Use unique IDs for active elements. Flag exact elements, roles, labels, focus behavior, or keyboard interactions that violate the rule, and note how to verify the fix with browser accessibility tooling or assistive tech.
