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, action-dense skill body: executable Swift for the common cases, a coherent setup-to-background-delivery workflow with explicit error recovery, and clean progressive disclosure into one real overflow reference. The only weaknesses are minor: a non-runnable balance-formatting snippet and small conciseness trims (duplicated TOC, padded switch scaffolding).
Suggestions
Make the balance-reading snippet executable: wrap the `switch balance.currentBalance` block in a function and replace the bare `formatBalance(bal)` / "Unknown" expressions with assignments or prints so it can be copy-pasted like the other examples.
Trim the Contents list (or the per-section headers it duplicates) and collapse the authorization switch to a comment noting the three cases, saving ~25 lines without losing information.
Consolidate the version-availability facts currently spread across the intro (Swift 6.3, iOS 17.4/18/18.4/26) into a single short availability note near Data Availability so they are stated once.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | The body is lean and code-first, assuming competence (no explainer fluff about Wallet or Swift), with a tight Common Mistakes section. Minor trims remain: the 12-item Contents TOC duplicates the section headers one screen below, switch scaffolding with bare `break` cases pads the authorization example, and the version-laden intro sentence could be tightened. This sits between anchors 4 and 5 — efficient with minor over-explanation — rather than the every-token-earns-its-place ideal of 5. | 4 / 5 |
Actionability | Nearly all guidance is executable, copy-paste Swift (availability guard, authorization, queries, history loop with token persistence, TransactionPicker view, saveOrder, extension skeleton). The gap is the balance-reading snippet (lines 162–167), which mixes bare `formatBalance(bal)` expressions with a stray string literal outside any function and is not runnable as written — a minor gap matching anchor 4 rather than the fully-executable anchor 5. | 4 / 5 |
Workflow Clarity | The sequence is clear — entitlements/requirements → project config → availability check → authorization → querying → history/sync → background delivery — with explicit error-recovery feedback loops (discard an invalid HistoryToken and immediately resync the affected stream; catch FinanceError.dataRestricted), DON'T/DO mistake pairs, and a 17-item Review Checklist acting as validation checkpoints. This matches the anchor-5 description of explicit validation steps, feedback loops, and checklists; anchor 4 would lack some of these checkpoints. | 5 / 5 |
Progressive Disclosure | The skill keeps core patterns inline and pushes overflow material to a single, clearly signaled, one-level-deep reference (references/financekit-patterns.md, which exists and covers exactly what the citations promise: field tables, query patterns, credit/debit interpretation). Anchor 5 fits: clear overview, well-signaled one-level references, easy navigation; there is no nesting or buried reference content that would drop it to 4. | 5 / 5 |
