90%Weight 40%Scale 1-5Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.
An excellent, dense, action-first skill: executable Kotlin throughout, decision tables instead of prose, and zero padding. The only structural refinements are adding an explicit post-purchase failure path and moving bulk API/type detail into a references file.
Suggestions
Add a short error-recovery step after the entitlement check in 3.6, e.g. what to inspect when customerInfo.entitlements is not active (grace period, account hold, pending purchase).
Move the full type-field reference (Phase 1 type list and PricingPhase fields) into a references/ file, keeping SKILL.md to the overview and common-case code paths.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | The body is lean and table-driven; it explains nothing Claude already knows (no 'what is a subscription' padding) and every line carries RevenueCat-specific knowledge, e.g. 'billingPeriod.value is the count in the period's unit, not days. A P1W period gives value = 1, unit = WEEK.' | 5 / 5 |
Actionability | Seven copy-paste-ready Kotlin snippets cover the common cases end to end: fetching offerings, purchasing with the default option, filtering subscriptionOptions by tag, building period labels, prepaid configuration, and entitlement checks after purchase. | 5 / 5 |
Workflow Clarity | The Understand → Plan → Execute sequence is clear, the Plan phase poses explicit decision questions, the decision-summary table acts as a checklist, and section 3.6 validates access after purchase. It is not a 5 because there is no error-recovery loop for the post-purchase check (e.g., what to do if the entitlement is not active) and no validation checkpoints in the purchase flow itself. | 4 / 5 |
Progressive Disclosure | Good structure: phased sections, a decision-summary table, and a clearly signaled one-level reference link at the end. It is not a 5 because the ~165-line body inlines the full type reference and every code recipe in SKILL.md with no bundle split — above the under-50-line simple-skill case where inline sections alone would suffice. | 4 / 5 |
