In plain words
What is it for?
Use it when setting default window sizes, controlling resizing, adding toolbar actions, or making toolbars customisable.
Why use it?
It gives developers ready references for common macOS interface arrangements instead of requiring them to work out each pattern from scratch.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

layout scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 1mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Layout Patterns (macOS)

Window Default Sizing

WindowGroup {
    ContentView()
}
.defaultSize(width: 900, height: 600)

Window Resizability

// Allow free resizing with a minimum content size
WindowGroup {
    ContentView()
        .frame(minWidth: 600, minHeight: 400)
}
.windowResizability(.contentMinSize)

// Fixed content size (non-resizable)
Window("Preferences", id: "prefs") {
    PreferencesView()
}
.windowResizability(.contentSize)

Toolbar

NavigationSplitView {
    SidebarView()
} detail: {
    DetailView()
        .toolbar {
            ToolbarItem(placement: .principal) {
                Text("Document")
                    .font(AppTheme.Fonts.headline)
            }
            ToolbarItemGroup {
                Button("Share", systemImage: "square.and.arrow.up") { share() }
                Button("Settings", systemImage: "gear") { openSettings() }
            }
        }
}

Customizable Toolbar

.toolbar(id: "editor") {
    ToolbarItem(id: "bold", placement: .automatic) {
        Button("Bold", systemImage: "bold") { toggleBold() }
    }
    ToolbarItem(id: "italic", placement: .automatic) {
        Button("Italic", systemImage: "italic") { toggleItalic() }
    }
}
.toolbarRole(.editor)
NavigationSplitView {
    SidebarView()
        .navigationSplitViewColumnWidth(min: 180, ideal: 220, max: 300)
} content: {
    ContentList()
        .navigationSplitViewColumnWidth(min: 250, ideal: 300)
} detail: {
    DetailView()
}

Adaptive Sizing

GeometryReader { geometry in
    let columns = geometry.size.width > 800
        ? [GridItem(.adaptive(minimum: 200))]
        : [GridItem(.adaptive(minimum: 150))]

    LazyVGrid(columns: columns) {
        ForEach(items) { item in
            ItemCard(item: item)
        }
    }
}

Dynamic Type + Accessibility

@Environment(\.dynamicTypeSize) var dynamicTypeSize

var body: some View {
    VStack(spacing: AppTheme.Spacing.medium) {
        Text(title)
            .font(AppTheme.Fonts.headline)
        Text(subtitle)
            .font(AppTheme.Fonts.body)
    }
    .padding(AppTheme.Spacing.large)
}

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
