Use when reviewing rendered HTML, interactive components, or design-system patterns related to Use unique IDs for active elements. Check native semantics first, then inspect keyboard behavior, focus flow, accessible names, and screen-reader output where relevant.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Use unique IDs for active elements Duplicate IDs on active elements can cause browsers and assistive technologies to skip items, misdirect focus, or fail to trigger the correct action. ## Quick Reference - Ensure all focusable elements (links, buttons, inputs) have unique id values - Avoid duplicate IDs that can break keyboard navigation and focus management - Prevent screen reader confusion when navigating interactive controls ## Check Search for duplicate id attributes on focusable or active HTML elements. ## Fix Assign a unique id to each active element to ensure correct focus handling and accessibility. ## Explain Explain how unique IDs on active elements prevent navigation errors for keyboard and screen reader users. ## Code Review 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. --- For full implementation details, code examples, and framework-specific guidance, see `references/rule.md`. …

How to install
mdr add thedaviddias/front-end-checklist/duplicate-id-active@sha256:6b77428e1744a481The line at the top of this page pins the label git:20261004.4b0ddb9, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
