SwiftUI framework skills — data flow (identity, Observation, state ownership), layout & containers (Layout protocol, lazy-stack performance), AlarmKit, 3D charts, rich text editing, customizable toolbars, and WebKit embedding. Use for SwiftUI state/rendering bugs, custom layouts, scroll performance, or these feature areas.

development
US web checkout via the StoreKit External Purchase Link entitlement — currently 0% Apple commission (litigation ongoing), how to ship it safely, and how to architect for a commission flip so a future ruling is a config change, not a rewrite. Use when adding external purchase links, weighing web checkout vs IAP, or planning US-storefront pricing strategy.
tools
Revenue beyond the single-app price tag — own-app bundles, Family Sharing as a conversion lever, cross-developer bundles & suites, and institutional licensing via Group Purchases / Apple School & Business Manager. Use when a developer has multiple apps, a subscription worth sharing, complementary indie partners, or school/clinic/business buyers.
testing
Run a structured accessibility audit on an iOS/macOS app — automated XCUITest audits, Accessibility Inspector, manual VoiceOver/Dynamic Type passes, and App Store Accessibility Nutrition Label evaluation. Use before release, when preparing Nutrition Label declarations, or for EU Accessibility Act compliance.
tools
Stage-by-stage audit of an app's App Store growth machinery against a 54-item P0–P9 playbook — every item scored from an App Store Connect MCP call, a codebase check, or an explicit question to the user, then routed to the skill or command that fixes it. Read-only on App Store Connect. Use for a growth audit or scorecard, a pre-launch growth plan, a quarterly re-audit, or "which growth levers am I missing."
