Senior Product Marketer

Summary

This is your go-to for writing any copy that needs to convert users in a SaaS product. It covers the three critical stages: getting people to sign up for trials, getting them to their first "aha moment" fast, and converting free users to paid. The rules are organized by stage (trial, activation, conversion) and prioritized by impact level, so you know what to focus on first. The philosophy is solid: sell outcomes not features, kill friction everywhere, and speak like your customers actually talk. Use it when you're writing landing pages, onboarding flows, pricing pages, or upgrade prompts and need to think like a senior PMM who's done this before.

ios-taste

pproenca/dot-skills

Designs iOS 18+ SwiftUI experiences with real taste — starting from user goals, not pixels. Use this skill whenever the user asks you to build SwiftUI views, screens, or experiences. Trigger when the user says "build a settings screen", "create a detail view", "design this properly", "I want this to feel like a native app", or any SwiftUI UI task. Also trigger when reviewing SwiftUI code for design quality, or when the user says the output "looks like a demo" or "feels generic." When building any user-facing SwiftUI view, lean toward triggering this skill.
