Properly implemented password fields improve security by working with password managers, helping users create strong passwords, and providing accessible controls for all users.
Verify password fields use type='password', have proper autocomplete values, and include accessible show/hide toggles.
Implement password fields with autocomplete='new-password' or 'current-password', accessible toggle buttons, and optional strength meters.
Explain security and UX best practices for password fields including autocomplete attributes and accessible reveal functionality.
Review server config, headers, forms, and integration points related to Secure password input fields. Flag exact responses, cookies, or browser behaviors that violate the rule, and verify them against the effective production-like response.
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.
