85%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, code-first skill: clear sequenced workflow with validation gates, appropriate offloading of advanced patterns to a one-level reference, and a useful review checklist. The only deductions are minor — some repeated scope phrasing, one meta-sentence, and a few code placeholders for app-specific helpers.
Suggestions
State the "physical goods, real-world services, donations, and eligible recurring payments" scope once (e.g., in the intro or Common Mistakes) and reference it from the checklist instead of repeating it verbatim three times.
Remove or rewrite the meta-sentence "Name invalid-data and invalid-signature failures explicitly instead of hiding them behind a bare try? in review guidance" as user-facing guidance (e.g., "Surface invalid-data and invalid-signature errors to the user rather than swallowing them with try?"), and drop the try? usage in the SwiftUI wallet example accordingly.
Flesh out the code examples that rely on undefined helpers — show the paymentService.process call as a clearly-marked stub comment, and place the addPassToWallet example inside a view-controller context so present() is unambiguous.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | The body is dominated by executable code with terse, non-obvious domain guidance (e.g., "PassKit amount APIs take NSDecimalNumber, not Double"; "The last item in paymentSummaryItems is treated as the total"), fitting the 4 anchor ("Efficient; minor instances of over-explanation that could be trimmed"). It is not a 5 because the scope phrase "physical goods, real-world services, donations, and eligible recurring payments" is repeated three times (intro, Common Mistakes, checklist), and the sentence "Name invalid-data and invalid-signature failures explicitly instead of hiding them behind a bare try? in review guidance" is meta-commentary about the skill itself rather than user-facing instruction. | 4 / 5 |
Actionability | Concrete, mostly copy-paste-ready Swift covers all common cases (availability check, both button APIs, request construction, presentation with delegate retention, authorization, shipping updates, pass adding, pass library), matching the 4 anchor. It falls short of 5 because several examples invoke undefined helpers — `paymentService.process(payment.token)`, `recalculateItems(with:)`, `showRecoverablePassError(error)`, and a bare `present(addController, animated: true)` with no enclosing view-controller context — leaving minor gaps the reader must fill. | 4 / 5 |
Workflow Clarity | The sections form a coherent build sequence (Setup → availability check → button → payment request → present sheet → authorization/shipping → wallet passes) with explicit validation checkpoints (canMakePayments before showing UI, canAddPasses before add-pass UI, present completion handling, catch-and-surface for invalid pass data) and a full Review Checklist, matching the 5 anchor's "clear sequence with explicit validation steps ... checklists for complex processes". It is not a 4 because the key checkpoints are explicit rather than implicit. | 5 / 5 |
Progressive Disclosure | The bundle structure matches the 5 anchor: SKILL.md holds the common flows inline, while advanced material (recurring/deferred payments, coupons, multi-merchant, pass bundles, pass update web services) is split into a single one-level-deep file that is clearly signaled twice ("read references/wallet-passes.md" in Checking Pass Library, and again in References) and verified to exist with no nested references. A Contents TOC plus per-section headings make navigation easy; the reference file itself is self-contained with its own internal TOC. | 5 / 5 |
