Conciseness

The ~50-line body is lean and dense with non-obvious, decision-relevant guidance: ordered platform detection rules, the offering-vs-entitlement distinction ("Gate premium features on the entitlement, not on the offering"), per-platform close-button flags, and a fallback-layout diagnosis. Nothing explains concepts Claude already knows and every token earns its place, matching the level-5 anchor.

Actionability

The guidance is highly concrete — exact packages ("react-native-purchases-ui", "com.revenuecat.purchases:purchases-ui"), exact flags ("displayCloseButton = true", "setShouldDisplayDismissButton(true)"), and executable detection rules — but the body contains no present-the-paywall snippet, delegating it to platform files that are not present in this bundle. This is the level-4 anchor ('mostly executable guidance with minor gaps') rather than 5 ('copy-paste ready code'), since the core code lives in unverifiable external files.

Workflow Clarity

The sequence is clear and deterministic (detect platform with ordered first-match rules and tie-breaking → shared concepts → implementation → verify), and the Verify section is an explicit validation checklist with a feedback loop: "If the paywall shows the default fallback layout instead of your template, the offering does not have a paywall attached in the dashboard. Fix this in the dashboard, then retry." This matches the level-5 anchor (explicit validation steps plus error-recovery loops).

Progressive Disclosure

The body is a well-signaled, one-level-deep overview that tells each platform file's contents ("install command, exact snippet to present the paywall, and the callback shape you listen to"), which matches the level-5 structure. However, none of the five referenced "platforms/*.md" files exist in the provided bundle (no platforms/, references/, scripts/, or assets/ directories), so the referenced paths cannot be verified as real files — a minor gap that brings it to the level-4 anchor.

Specificity

The description lists multiple concrete actions at API-name granularity — "Display a RevenueCat paywall inside an app using the RevenueCatUI SDK", "present PaywallView", "launch PaywallActivity", "call presentPaywall or presentPaywallIfNeeded", "gate a premium screen with a paywall" — with comprehensive coverage across all five supported platforms, matching the level-5 anchor rather than 4 (no coverage gaps within its niche).

Completeness

It explicitly answers both questions: what it does ("Display a RevenueCat paywall inside an app using the RevenueCatUI SDK") and when to use it ("Use when the user asks to add a paywall, show a RevenueCat paywall, present PaywallView, ..."), with concrete trigger phrases and platform scope. This matches the level-5 anchor exactly; the explicit 'Use when...' clause with concrete triggers rules out the level-4 anchor.

Trigger Term Quality

Trigger phrases are comprehensive and natural: "add a paywall", "show a RevenueCat paywall", "gate a premium screen with a paywall", "integrate RevenueCatUI", plus API synonyms (PaywallView / PaywallActivity, presentPaywall / presentPaywallIfNeeded) and an explicit platform enumeration (iOS, Android, Kotlin Multiplatform, Flutter, React Native). This matches the level-5 anchor (comprehensive natural terms including synonyms); it is well above the level-4 anchor's 'a few natural terms missing'.

Distinctiveness Conflict Risk

It occupies a clear niche (dashboard-templated RevenueCatUI paywall display) and explicitly resolves the closest sibling-skill conflict: "To create, edit, evaluate, or audit the dashboard paywall itself, use revenuecat-paywall-design." Minimal conflict risk matches the level-5 anchor rather than 4, since the main overlap is actively disambiguated.
