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.
The body is a well-structured, actionable overview with exemplary progressive disclosure into a real, verified bundle of four reference files. The main improvement opportunities are tightening token use (TOC, duplicate reference pointers, Mistakes/Checklist overlap) and making the fragmentary snippets (custom scheme handler, script examples) fully self-contained.
Suggestions
Remove the Contents table-of-contents and the repeated inline "See [references/...]" pointers (keeping only the final References section) to cut tokens without losing navigation, since the section headers and reference file names already make the structure discoverable.
Make the custom-scheme snippet self-contained — either define or stub DocsSchemeHandler, or state explicitly that its implementation is shown in references/local-content-and-custom-schemes.md — so the main-file example is copy-paste runnable.
Deduplicate Common Mistakes and Review Checklist, which restate the same points (OAuth, WKWebView fallback, callJavaScript function body, navigations try/catch, one WebPage per WebView, custom-scheme overuse); merging or cross-referencing them would tighten conciseness and sharpen the checklist as a validation pass.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | The body is efficient and focused on iOS 26 WebKit-for-SwiftUI API specifics Claude cannot be assumed to know, with no padding explaining familiar concepts. Minor trims remain: the 10-item Contents TOC, repeated "See [references/...]" pointers, the "Apple's WWDC25 guidance frames..." framing sentence, and notable overlap between Common Mistakes and Review Checklist. This fits anchor 4 (efficient with minor instances that could be trimmed) rather than anchor 5, but is tighter than anchor 3's unnecessary explanation. | 4 / 5 |
Actionability | Concrete, mostly executable Swift code appears in every section ("struct ArticleView: View { WebView(url: url) }", the ArticleModel/WebPage load loop, the full ArticleNavigationDecider, callJavaScript examples, and the URLSchemeHandler configuration). It stops short of anchor 5 because several snippets are fragments: "DocsSchemeHandler(bundle: .main)" is never defined in the file and the JavaScript script snippets are bare let-statements without runnable context. It is well above anchor 3 since the guidance is real code, not pseudocode. | 4 / 5 |
Workflow Clarity | "Use the narrowest tool that matches the job" plus the container-choice table gives a clear decision entry point, sections progress from display to observation to policy to JS to local content, and the Review Checklist supplies checkpoints with error paths noted ("Handle WebPage.NavigationError or cancellation"). It matches anchor 4 rather than anchor 5 because there is no explicit multi-step build sequence with inline validation and feedback loops; it is above anchor 3 because checkpoints are present and clearly signaled. | 4 / 5 |
Progressive Disclosure | The SKILL.md is a genuine overview: each section keeps a short example inline and defers depth to one-level-deep references ("See [references/loading-and-observation.md]", etc.), all four referenced files exist and are non-empty, and the References section labels all of them. This matches anchor 5 (clear overview, well-signaled one-level-deep references, easy navigation); it does not exhibit anchor 4's organization gaps. | 5 / 5 |
