Defines and tracks UX success through metrics, measurement frameworks, and experimentation. Part of the Intent design strategy system. Connects design decisions to observable evidence — did the thing we built actually help? Guards against measurement becoming manipulation. Trigger when: defining success metrics, designing A/B tests, building measurement frameworks, analyzing funnels, reviewing metric dashboards, questioning whether the right things are being measured, or when someone says "how do we know if this worked," "what should we measure," "let's run a test," or "the numbers look good but something feels off." Also trigger for ethical measurement reviews and counter-metric definition.
Expert data science covering machine learning, statistical modeling, experimentation, predictive analytics, and advanced analytics.
Implement feature flags (toggles) for controlled feature rollouts, A/B testing, canary deployments, and kill switches. Use when deploying new features gradually, testing in production, or managing feature lifecycles.
Generate personalized cold email sequences (7-14 emails) with A/B test subject lines, follow-up timing recommendations, and integrated social proof. Creates multi-touch campaigns optimized for response rates. Use when users need outbound email campaigns, sales sequences, or lead generation emails.
6 ColdIQ messaging templates - Ask Before Pitch, Not Too Different Persona, Upfront Value, Leverage Content, and Why Are You Paying. Use when creating outreach campaigns, A/B testing message structures, or choosing a messaging approach.
Use this skill when planning user research, conducting usability tests, creating journey maps, or designing A/B experiments. Triggers on user interviews, usability testing, user journey maps, A/B test design, survey design, persona creation, card sorting, tree testing, and any task requiring user experience research methodology or analysis.
Expert CRO advisor that analyzes landing pages, product funnels, UI/UX friction, and provides data-driven A/B test ideas to maximize conversions, sign-ups, trials, and retention. Use when optimizing conversion rates, analyzing funnels, designing experiments, improving CTAs, reducing drop-offs, or when user mentions conversion rate, CRO, landing page optimization, A/B testing, or funnel analysis.
When the user wants to optimize free trial conversion -- including trial length, trial type selection, expiry flows, or trial email sequences. Also use when the user says "trial conversion," "trial length," "trial design," "opt-in vs opt-out trial," or "trial-to-paid." For activation, see activation-metrics. For feature gating, see feature-gating.
Feature flags, A/B testing, and adaptive optimization with Traffical. Use when adding features, modifying UI, changing algorithms, or anything affecting conversions. Check this skill when implementing new functionality that could benefit from gradual rollout or experimentation.
When the user wants to optimize a signup or registration flow -- including field selection, social auth, single-step vs multi-step forms, or mobile signup. Also use when the user says "signup conversion," "registration form," "reduce signup friction," "signup A/B test," or "signup drop-off." For post-signup onboarding, see product-onboarding. For activation measurement, see activation-metrics.
Conversion rate optimization (CRO) specialist covering landing pages, signup flows, onboarding, forms, popups, and in-app paywalls. Use when the user wants to improve conversion rates, optimize a page or flow, reduce form abandonment, improve signup completion, increase free-to-paid conversion, optimize popups, or fix a paywall screen. Also triggers for 'CRO', 'conversion rate', 'landing page optimization', 'signup optimization', 'user activation', 'upgrade screen', 'exit popup', 'form optimization', 'A/B test ideas', or any page or flow that isn't converting well enough.
Comprehensive guide for implementing feature flags and A/B tests using the Flags SDK (the `flags` npm package). Use when: (1) Creating or declaring feature flags with `flag()`, (2) Setting up feature flag providers/adapters (Vercel, Statsig, LaunchDarkly, PostHog, GrowthBook, Hypertune, Edge Config, OpenFeature, Flagsmith, Reflag, Split, Optimizely, or custom adapters), (3) Implementing precompute patterns for static pages with feature flags, (4) Setting up evaluation context with `identify` and `dedupe`, (5) Integrating the Flags Explorer / Vercel Toolbar, (6) Working with feature flags in Next.js (App Router, Pages Router, Middleware) or SvelteKit, (7) Writing custom adapters, (8) Encrypting/decrypting flag values for the toolbar, (9) Any task involving the `flags`, `flags/next`, `flags/sveltekit`, `flags/react`, or `@flags-sdk/*` packages. Triggers on: feature flags, A/B testing, experimentation, flags SDK, flag adapters, precompute flags, Flags Explorer, feature gates, flag overrides.
