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.
A dense, executable, well-sequenced skill body that assumes Claude's competence and provides copy-paste code plus a useful mistake table. The two four-scoring dimensions reflect a missing verify-retry loop and the absence of any bundle-file disclosure, both minor given the skill's focused scope.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | Lean and efficient throughout: a focused mode-selection table, one complete Kotlin example, and dense 'Common mistakes' and 'Notes' sections — no padding explaining what subscriptions or libraries are, and every paragraph carries actionable guidance. | 5 / 5 |
Actionability | Fully executable copy-paste Kotlin using PurchaseParams.Builder, GoogleProductChangeInfo, and awaitPurchase with error handling, plus a scenario→mode table and a concrete currentProductId derivation covering the common cases. | 5 / 5 |
Workflow Clarity | Clear four-phase sequence (Preconditions → Plan → Execute → Verify) with an explicit precondition checklist and a Verify phase, but the only error feedback loop is the purchase catch→showError path; there is no validate-then-retry loop for the verification step itself. | 4 / 5 |
Progressive Disclosure | Well-organized into clearly headed sections with one clearly signaled, one-level-deep external reference; however the skill is a single self-contained document with no bundle files, so there is no real cross-file disclosure to reward beyond the clean in-page structure. | 4 / 5 |
