UI Creation Skill

Purpose

Apply A/B testing insights to first-pass UI design so new screens are easy to understand, commercially effective, and trustworthy from day one.

When to Use

• Building a brand-new screen or flow for a new feature
• Creating new onboarding, landing, pricing, paywall, checkout, or PDP UI
• Drafting initial options for CTA copy, icon choice, pricing presentation, or form structure

Execution Steps

1. Define the screen's primary job
   • Narrow the goal to one core action (for example, start trial, complete purchase, finish onboarding).
2. Separate essential information from noise
   • Split content into must-have (decision-critical) and nice-to-have (supporting).
   • Design for both clarity and persuasion; treat them as separate quality checks.
3. Reduce flow friction early
   • Keep early steps lightweight, and move heavy inputs later when possible.
   • Prefer smart default + editable later when it fits the product.
4. Build trust and risk reduction into the UI
   • Make pricing terms, billing timing, cancellation, and return/refund conditions explicit.
   • Place trust signals (reviews, guarantees, evidence) near primary CTAs.
5. Prepare two persuasive angles
   • Feature-led vs benefit-led
   • Rational appeal vs emotional appeal
   • Action-focused CTA vs value-focused CTA
6. Output A/B-ready variants
   • Always provide 2-3 variants (A: baseline-friendly / B: strong change / C: balanced option).

Default Guidelines by Screen Type

Onboarding

• Minimize forced choices and mandatory upfront input; surface value first.
• If collecting multiple intents, avoid choice overload and reflect results immediately.
• For checklist-style flows, keep only actions tied to long-term retention.

Pricing / Plan Selection

• Preserve decision-critical comparison points (feature gaps, limits, support terms).
• If emphasizing a default plan, keep alternative plans clearly accessible.
• If showing monthly breakdown pricing, also show total cost and contract terms.

Paywall

• Design with hard-gate vs soft-gate variants in mind.
• Include gain-framed copy as a standard option.
• Use visuals to reinforce value context, not just decoration.

Checkout

• Remove unnecessary account creation and heavy input before purchase.
• Improve visibility of payment options and discoverability of switching paths.
• Show transparency copy (returns, cancellation, billing conditions) early.

PDP / LP

• Produce both feature-first and benefit-first versions.
• For dedicated landing pages, align messaging to traffic intent and reduce branching.
• Before adding new perks, improve visibility of existing benefits.

Output Format

Always return UI creation proposals in this structure.

## Goal
- [Primary user action this screen should drive]

## Target User and Context
- [Who arrives here and in what state]

## UI Variants
- Variant A: [Structure and intent]
- Variant B: [Structure and intent]
- Variant C (optional): [Balanced option]

## Copy and Elements
- Headline:
- Supporting copy:
- CTA:
- Trust signals:

## Expected Impact and Evaluation
- Primary metric: [CVR / completion rate / etc.]
- Secondary metrics: [drop-off / support tickets / retention / refunds / etc.]
- Guardrails: [Conditions that prevent trust or quality regression]

Guardrails

• Do not ship a change based on revenue uplift alone; include quality metrics (churn/refund/NPS).
• Avoid dark patterns (misleading emphasis, hidden terms, or ambiguous conditions).
• Treat simplification as a method, not a license to remove decision-critical information.
