78%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, lean reference skill with executable-style Swift examples, a useful review checklist, and exemplary progressive disclosure to a single one-level-deep reference file. The main gaps are snippet self-containment (undeclared properties, missing View wrappers) and the absence of an explicit verification step when writing or fixing gesture code.
Suggestions
Make the core code snippets self-contained — declare currentScale/currentAngle and wrap fragments in a minimal View struct — so they are copy-paste executable.
Add an explicit verification step after the Review Checklist (e.g., compile check or simulator test of the corrected gesture) to close the fix → validate feedback loop.
Trim the redundancy between Common Mistakes and the Review Checklist, and consider dropping the Contents TOC, to tighten token usage.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | The body is lean — a compact gesture table, terse code, and decision rules with no padding or explanations of concepts Claude already knows — but the Contents TOC and the Review Checklist partially duplicating Common Mistakes ("MagnifyGesture / RotateGesture on iOS 17+" appears in both) could be trimmed. Not 5: these minor redundancies mean not every token earns its place; not 3: there is no unnecessary explanation to remove. | 4 / 5 |
Actionability | Concrete Swift snippets cover every core gesture plus composition (e.g., the LongPressGesture/.updating example and the MagnifyGesture.simultaneously(with: RotateGesture()) example), but several fragments are not self-contained: `currentScale`/`currentAngle` are undeclared in the Magnify/Rotate lines and snippets omit enclosing View structs. Not 5: not fully copy-paste ready; not 3: the examples are real executable-style Swift, not pseudocode. | 4 / 5 |
Workflow Clarity | The Review Checklist supplies concrete checkpoints for review mode ("Correct modern gesture types used", "Bounds clamped on persisted pinch/rotation values in .onEnded") and sections flow concepts → mistakes → checklist, but there is no explicit sequence and no compile/test verification step for code the skill writes or fixes. Not 5: validation is checklist-only with no verify step or error-recovery loop; not 3: the checklist provides most checkpoints and the topical flow is clear. | 4 / 5 |
Progressive Disclosure | Clear overview in SKILL.md with one well-signaled, one-level-deep reference — "Full recipes, pinch-to-zoom-pan, drag-to-reorder, and UIKit interop: references/gesture-patterns.md" — and the bundle file exists, contains the promised recipes, and links only back to SKILL.md (no nested references). The split is appropriate: overview and core patterns inline, advanced recipes in the reference. | 5 / 5 |
