Incorrectly implemented tabs trap keyboard users or leave screen reader users unable to understand the relationship between tabs and their content.
Verify tabs use tablist/tab/tabpanel roles, aria-selected state, and arrow key navigation between tabs.
Implement tabs with role='tablist', role='tab', role='tabpanel', aria-selected, and proper keyboard interaction patterns.
Explain the ARIA tabs design pattern and how proper implementation ensures keyboard and screen reader accessibility.
Review templates, server-rendered HTML, and shared components that output markup related to Make tabs keyboard navigable. Flag exact elements, attributes, and routes where the rendered HTML violates the rule.
For full implementation details, code examples, and framework-specific guidance, see references/rule.md.

DecimalAI ran this skill against gemini-3.6-flash twice over the same eval suite — once with the skill loaded and once without — and compared the two runs case by case. 22 cases were attempted. The headline lift of +5 percentage points is the difference between those two pass rates over the 22 comparable cases.
Without the skill loaded, the model failed this case. With it loaded, the same prompt on the same model passed. This is one improved case from the latest verified run; every case, including any that regressed, is in the table above.
Other measured skills in the registry, with their headline benchmark lift.
