75%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.
A well-structured, information-dense body with a clear three-phase workflow, concrete code, and useful checklists, all focused on non-obvious version-specific facts rather than general knowledge. It falls short of top marks on conciseness (scattered time-sensitive dates), actionability (no code for the primary Path B integration), workflow clarity (no error-recovery loop), and disclosure (buried cross-skill pointer).
Suggestions
Consolidate time-sensitive version and date facts (10.27.1, PBL 8.3.0, the Japan program deadlines) into a single 'Support status' or 'Deprecated programs' section so the prose stays evergreen and scannable.
Add a minimal copy-paste example (or an explicit step-by-step pointer) for the most common Path B flow — user choice billing via the Play Billing Library — since Phase 3 currently defers it entirely to another skill.
Signpost the google-play/alternative-billing skill as a named reference (e.g., in the References section or a 'Depends on' line) instead of referencing it mid-sentence in Phase 2, and add a brief 'what to do if a verification step fails' note to close the error-recovery gap.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | Mostly lean, version-dense content that earns its tokens ("RevenueCat 10.27.1 is built against Play Billing Library 8.3.0"), with only minor trimmable framing ("This skill tells you which pieces the RevenueCat Android SDK covers"). Time-sensitive dates and version numbers (October 2026, September 30, 2026, March 31, 2027) are scattered throughout rather than consolidated into a dedicated status/deprecated section, keeping it below the 5 anchor. | 4 / 5 |
Actionability | Two executable Kotlin snippets (PurchasesConfiguration with purchasesAreCompletedBy, webCheckoutURL intent launch) and concrete API names (enableBillingProgram, BillingProgram.BILLING_CHOICE, getBillingChoiceInfoAsync) give mostly executable guidance. The most common Path B case — implementing user choice billing via the Play Billing Library — has no code and defers to the google-play/alternative-billing skill, so examples do not fully cover the common cases (below the 5 anchor). | 4 / 5 |
Workflow Clarity | Clear Discovery → Plan → Execute sequence with a planning checklist and explicit verification checklist ("Acknowledgement happens exactly once per purchase, with no double-handling"). No error-recovery guidance for when a verification step fails (no validate → fix → retry loop), matching the 4 anchor rather than 5; the skill is not destructive or batch, so the cap at 3 does not apply. | 4 / 5 |
Progressive Disclosure | Well-organized sections with no bundle files (the ~85-line body is self-contained at appropriate depth) and a clearly labeled References list of external URLs. Minor gaps: the pointer to the google-play/alternative-billing skill is buried mid-prose in Phase 2 rather than clearly signposted, and the version/date support matrix could be split out — fits the 4 anchor, short of 5's well-signaled one-level-deep reference structure. | 4 / 5 |
