77%Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.
This is a well-structured skill with excellent workflow clarity and conciseness. The shared concepts section is particularly strong, encoding platform-specific nuances (cancellation handling patterns) and critical anti-patterns (don't unlock in callback) that Claude wouldn't know. The main weakness is that all executable implementation is deferred to platform files that aren't present in the bundle, leaving the skill without concrete, copy-paste-ready code.
Suggestions
Provide the referenced platform files (platforms/ios.md, platforms/android.md, etc.) in the bundle so the progressive disclosure structure is functional rather than aspirational.
Consider adding at least one inline code example (e.g., a minimal Swift or Kotlin purchase function) in the shared concepts section so the skill has some executable guidance even without the platform files.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | The content is lean and efficient. It avoids explaining what RevenueCat is, what purchases are, or how SDKs work in general. Every section delivers information Claude wouldn't already know—platform detection heuristics, SDK-specific cancellation patterns, and the critical 'do not unlock content in the purchase callback' rule. No wasted tokens. | 3 / 3 |
Actionability | The skill provides concrete platform detection logic and clear behavioral rules (e.g., how to handle cancellation per platform), but the actual implementation code is deferred entirely to platform files which are not provided in the bundle. Without those files, Claude has no executable code to work from—just conceptual guidance about what to call. | 2 / 3 |
Workflow Clarity | The workflow is clearly sequenced: detect platform → understand shared concepts → read platform-specific implementation → verify. The verification section (Step 4) provides explicit validation checkpoints covering success, cancellation, duplicate purchase, and restore scenarios. The feedback loop of 'do not claim it works until these checks pass' is well-defined. | 3 / 3 |
Progressive Disclosure | The structure is well-designed with clear references to platform-specific files (platforms/ios.md, etc.) and cross-references to related skills (revenuecat-paywall, revenuecat-entitlements-gate). However, no bundle files were provided, meaning the referenced platform files don't actually exist in the evaluated bundle, making the progressive disclosure structure aspirational rather than functional. | 2 / 3 |
