What problem does it solve? Growth surfaces such as onboarding flows, paywalls, and landing pages are often designed without a defined conversion event, shipped without instrumentation, or padded with dark patterns that erode trust. This Skill turns conversion design into a disciplined, designer-owned practice with named metrics, pricing awareness, and a mandatory ethics filter. ## Core Features & Use Cases - Conversion-event-first method: Names the single conversion event, activation metric, and guardrail metrics before any screen is sketched, then designs the shortest honest path to it. - Surface checklists: Provides concrete checklists for onboarding/first-run, upgrade prompts, paywalls and trials, and launch/landing pages grounded in Nielsen Norman Group research. - Ethical-persuasion filter: Screens every tactic through five tests (Symmetry, Honesty, Reversibility, Informed, Portfolio) plus a named dark-pattern blacklist covering confirmshaming, roach motels, fake scarcity, and forced continuity. - Use Case: Designing a salon booking app's first-run flow — cut a 6-field signup to 2 fields, move permission prompts to post-booking, reject a preselected SMS checkbox, and ship instrumentation with guardrail metrics like cancellation and opt-out rates. ## Quick Start Use the design-growth-surfaces skill to redesign our onboarding flow so it drives first booking, with an ethics check on every persuasion tactic and metrics defined before any screens.
