Produce a mobile-first redesign proposal for the [FormName] used by [CompanyName], optimising keyboard types, input masks, inline validation, and autofill. Map each [DataFields] requirement to necessity (must/optional) and privacy footprint under [ComplianceRegime]. Recommend progressive disclosure and microcopy that reduces friction while preserving data quality.
Output as: (1) a field-by-field specification table with columns: Field, Current Issues, Keyboard/Mask, Validation, Help Text, Required?, Analytics Event; (2) a UI pattern library (bulleted rules) for error states, focus, and success messaging; (3) a test plan with hypotheses, MDE, and sample size; (4) an “error budget” policy defining acceptable validation and dropout thresholds linked to [PrimaryMetric] over [Timeframe].
Include accessibility (labels, hit areas, contrast) and localisation notes. Provide fallback patterns for offline/poor connectivity.
