Your singular job is to do two things: + +- Find questions that are big sources of confusion for lots of employees at the company, generally about things that affect a large portion of the employee base +- Attempt to give a nice summarized answer to that question in order to minimize confusion. + +Some examples of areas that may be interesting to folks: recent corporate events (fundraising, new executives, etc.), upcoming launches, hiring progress, changes to vision or focus, etc. + + +## Tools Available +You should use the company's available tools, where communication and work happens. For most companies, it looks something like this: +- Slack: questions being asked across the company - it could be questions in response to posts with lots of responses, questions being asked with lots of reactions or thumbs up to show support, or anything else to show that a large number of employees want to ask the same things +- Email: emails with FAQs written directly in them can be a good source as well +- Documents: docs in places like Google Drive, linked on calendar events, etc. can also be a good source of FAQs, either directly added or inferred based on the contents of the doc + +## Formatting +The formatting should be pretty basic: + +- *Question*: [insert question - 1 sentence] +- *Answer*: [insert answer - 1-2 sentence] + +## Guidance +Make sure you're being holistic in your questions. Don't focus too much on just the user in question or the team they are a part of, but try to capture the entire company. Try to be as holistic as you can in reading all the tools available, producing responses that are relevant to all at the company. + +## Answer Guidelines +- Base answers on official company communications when possible +- If information is uncertain, indicate that clearly +- Link to authoritative sources (docs, announcements, emails) +- Keep tone professional but approachable +- Flag if a question requires executive input or official response \ No newline at end of file diff --git a/skills/internal-comms/examples/general-comms.md b/skills/internal-comms/examples/general-comms.md new file mode 100644 index 0000000..0ea9770 --- /dev/null +++ b/skills/internal-comms/examples/general-comms.md @@ -0,0 +1,16 @@ + ## Instructions + You are being asked to write internal company communication that doesn't fit into the standard formats (3P + updates, newsletters, or FAQs). + + Before proceeding: + 1.

catalog variants for custom colors (Any/Dark Appearance) +- No color-only information (pair with icons or text) +- Contrast ratio >= 4.5:1 for normal text, 3:1 for large text + +### Accessibility +- Labels on icon buttons (`.accessibilityLabel()`) +- Reduce motion respected (`@Environment(\.accessibilityReduceMotion)`) +- Logical reading order (`.accessibilitySortPriority()`) +- Support Bold Text, Increase Contrast preferences + +### Navigation +- Tab bar (3-5 sections) stays visible during navigation +- Back swipe works (never override system gestures) +- State preserved across tabs

The interface should feel invisible—users focus on their tasks, not the UI. + +**Key mindsets:** + +1. **Let content breathe** — Use full-screen layouts, minimize borders and boxes, let images and text take center stage + +2. **Leverage system conventions** — Users already know how iOS works; don't reinvent navigation, gestures, or controls + +3. **Design for fingers** — Touch is imprecise; generous tap targets and forgiving gesture recognition matter more than pixel-perfect layouts + +4. **Respect user choices** — Honor Dynamic Type, Dark Mode, Reduce Motion, and other accessibility settings as first-class requirements + +**iOS 26+ Liquid Glass:** +The latest iOS introduces translucent UI elements that respond to lighting and content behind them. Typography is bolder, text tends left-aligned for easier scanning. + +--- + +## 1. Layout & Safe Areas + +**Impact:** CRITICAL + +### 1.1 Minimum 44pt Touch Targets + +All interactive elements must have minimum 44x44 **points** (not pixels—points scale with screen density). + +```swift +Button(action: handleTap) { + Image(systemName: "heart.fill") +} +.frame(minWidth: 44, minHeight: 44) +``` + +Avoid placing critical interactions near screen edges where system gestures operate. + +### 1.2 Respect Safe Areas + +Never place interactive or essential content under the status bar, Dynamic Island, or home indicator. SwiftUI respects safe areas by default. Use `.ignoresSafeArea()` only for background fills, images, or decorative elements—never for text or interactive controls. + +```swift +ZStack { + LinearGradient(colors: [.blue, .purple], startPoint: .top, endPoint: .bottom) + .ignoresSafeArea() + + VStack { + Text("Welcome") + .font(.largeTitle) + Button("Get Started") { } + } +} +``` + +### 1.3 Primary Actions in Thumb Zone + +Place primary actions at the bottom of the screen where the user's thumb naturally rests. Secondary actions and navigation belong at the top. + +```swift +VStack { + ScrollView { + // Content + } + + Spacer() + + Button("Submit") { submit() } + .buttonStyle(.borderedProminent) + .padding(.horizontal) + .padding(.bottom) +} +``` + +### 1.4 Support All Screen Sizes + +Design for iPhone SE (375pt) through iPad Pro (1024pt+). Use Size Classes to adapt: + +```swift +@Environment(\.horizontalSizeClass) private var sizeClass + +var body: some View { + if sizeClass == .compact { + VStack { content } + } else { + HStack { content } + } +} +``` + +| Size Class | Devices | +|------------|---------| +| Compact width | iPhone portrait, small iPhone landscape | +| Regular width | iPad, large iPhone landscape | + +Use flexible layouts, avoid hardcoded widths: + +```swift +HStack(spacing: 16) { + ForEach(categories) { category in + CategoryCard(category: category) + .frame(maxWidth: .infinity) + } +} +``` + +### 1.5 8pt Grid Alignment + +Align spacing, padding, and element sizes to multiples of 8 points (8, 16, 24, 32, 40, 48). Use 4pt for fine adjustments. + +### 1.6 Landscape Support + +Support landscape orientation unless the app is task-specific (e.g., camera). Use `ViewThatFits` or `GeometryReader` for adaptive layouts. + +```swift +ViewThatFits { + HStack { contentViews } + VStack { contentViews } +} +``` + +--- + +## 2. Navigation + +**Impact:** CRITICAL + +### 2.1 Tab Bar for Top-Level Sections + +Use a tab bar at the bottom of the screen for 3 to 5 top-level sections. Each tab should represent a distinct category of content or functionality. + +```swift +TabView(selection: $selectedTab) { + HomeView() + .tabItem { + Label("Home", systemImage: "house") + } + .tag(Tab.home) + + DiscoverView() + .tabItem { + Label("Discover", systemImage: "magnifyingglass") + } + .tag(Tab.discover) + + AccountView() + .tabItem { + Label("Account", systemImage: "person") + } + .tag(Tab.account) +} +``` + +### 2.2 Navigation Architecture + +**Tab Bar (Flat)** — For 3-5 equal-importance sections +- Always visible except when covered by modals +- Each tab maintains its own navigation stack +- Most important content leftmost (easier thumb access) + +**Hierarchical (Drill-Down)** — For tree-structured info +- Push/pop navigation with back button +- Minimize depth (3-4 levels max) +- Provide search as escape hatch for deep trees + +**Modal (Focused Tasks)** — For self-contained workflows +- Full-screen for critical tasks +- Page sheet for dismissible tasks (swipe-down) +- Clear Done/Cancel with confirmation if data loss possible + +Never use hamburger menus—they reduce feature discoverability significantly. + +### 2.3 Large Titles in Primary Views + +Use `.navigationBarTitleDisplayMode(.large)` for top-level views. Titles transition to inline when the user scrolls. + +```swift +NavigationStack { + List(conversations) { conversation in + ConversationRow(conversation: conversation) + } + .navigationTitle("Inbox") + .navigationBarTitleDisplayMode(.large) +} +``` + +### 2.4 Never Override Back Swipe + +The swipe-from-left-edge gesture for back navigation is a system-level expectation. Never attach custom gesture recognizers that interfere with it. + +### 2.5 Use NavigationStack for Hierarchical Content + +Use `NavigationStack` (not the deprecated `NavigationView`) for drill-down content. Use `NavigationPath` for programmatic navigation. + +```swift +@State private var navPath = NavigationPath() + +NavigationStack(path: $navPath) { + List(products) { product in + NavigationLink(value: product) { + ProductRow(product: product) + } + } + .navigationDestination(for: Product.self) { product in + ProductDetailView(product: product) + } +} +``` + +### 2.6 Preserve State Across Navigation + +When users navigate back and then forward, or switch tabs, restore the previous scroll position and input state. + +```swift +@SceneStorage("selectedTab") private var selectedTab = Tab.home +@SceneStorage("scrollPosition") private var scrollPosition: String? +``` + +--- + +## 3. Typography & Dynamic Type + +**Impact:** HIGH + +### 3.1 Use Built-in Text Styles + +Always use semantic text styles—they scale with Dynamic Type automatically: + +| Style | Usage | +|-------|-------| +| `.largeTitle` | Screen titles | +| `.title`, `.title2`, `.title3` | Section headers | +| `.headline` | Emphasized body text | +| `.body` | Primary content (17pt default) | +| `.callout` | Secondary emphasized | +| `.subheadline` | Supporting labels | +| `.footnote`, `.caption` | Tertiary info | +| `.caption2` | Minimum size (11pt) | + +```swift +VStack(alignment: .leading, spacing: 8) { + Text("Article Title") + .font(.headline) + + Text("Published by Author Name") + .font(.subheadline) + .foregroundStyle(.secondary) + + Text(articleBody) + .font(.body) +} +``` + +### 3.2 Support Dynamic Type Including Accessibility Sizes + +Dynamic Type can scale text up to approximately 200% at the largest accessibility sizes. Layouts must reflow—never truncate or clip essential text. + +```swift +@Environment(\.dynamicTypeSize) private var typeSize + +var body: some View { + if typeSize.isAccessibilitySize { + VStack(alignment: .leading) { content } + } else { + HStack { content } + } +} +``` + +### 3.3 Custom Fonts Must Scale + +If you use a custom typeface, scale it with `Font.custom(_:size:relativeTo:)` so it responds to Dynamic Type. + +```swift +Text("Brand Text") + .font(.custom("Avenir-Medium", size: 17, relativeTo: .body)) +``` + +### 3.4 SF Pro as System Font + +Use the system font (SF Pro) unless brand requirements dictate otherwise. SF Pro is optimized for legibility on Apple displays. + +### 3.5 Minimum 11pt Text + +Never display text smaller than 11pt. Prefer 17pt for body text. Use the `caption2` style (11pt) as the absolute minimum. + +### 3.6 Hierarchy Through Weight and Size + +Establish visual hierarchy through font weight and size. Do not rely solely on color to differentiate text levels. + +### 3.7 SF Symbols + +Use SF Symbols (6,900+ icons) instead of custom image assets: + +```swift +// Basic usage with automatic text alignment +Label("Favorites", systemImage: "star.fill") + +// Rendering modes +Image(systemName: "cloud.sun.rain") + .symbolRenderingMode(.hierarchical) // or .multicolor, .palette + .imageScale(.large) // .small, .medium, .large +``` + +SF Symbols automatically match text weight, scale with Dynamic Type, and align to text baselines. Let them size naturally—don't force them into fixed-dimension containers. + +--- + +## 4. Color & Dark Mode + +**Impact:** HIGH + +### 4.1 Use Semantic System Colors + +Never use hard-coded RGB, hex, or `.black`/`.white` directly. Use semantic colors: + +**Labels:** +- `.primary`, `.secondary`, `.tertiary`, `.quaternary` + +**Backgrounds:** +- `Color(.systemBackground)` — primary surface +- `Color(.secondarySystemBackground)` — cards, grouped +- `Color(.tertiarySystemBackground)` — nested elements + +**System Colors (adapt to appearance):** +- `.blue`, `.red`, `.green`, `.orange`, `.yellow`, `.purple`, `.pink`, `.cyan`, `.mint`, `.teal`, `.indigo`, `.brown`, `.gray` + +```swift +VStack { + Text("Primary content") + .foregroundStyle(.primary) + + Text("Supporting info") + .foregroundStyle(.secondary) +} +.background(Color(.systemBackground)) +``` + +### 4.2 Custom Colors Need 4 Variants + +For custom colors, define in asset catalog with all appearance combinations: +1. Light mode +2. Dark mode +3. Light mode + High Contrast +4. Dark mode + High Contrast + +```swift +Text("Branded element") + .foregroundStyle(Color("AccentBrand")) +``` + +For dynamic colors in code: + +```swift +let dynamicColor = UIColor { traits in + traits.userInterfaceStyle == .dark + ? UIColor(red: 0.9, green: 0.9, blue: 1.0, alpha: 1.0) + : UIColor(red: 0.1, green: 0.1, blue: 0.2, alpha: 1.0) +} +``` + +### 4.3 Never Rely on Color Alone + +Always pair color with text, icons, or shapes to convey meaning. Approximately 8% of men have some form of color vision deficiency. + +```swift +HStack(spacing: 6) { + Image(systemName: "exclamationmark.triangle.fill") + Text("Connection failed") +} +.foregroundStyle(.red) +``` + +### 4.4 4.5:1 Contrast Ratio Minimum + +All text must meet WCAG AA contrast ratios: 4.5:1 for normal text, 3:1 for large text (18pt+ or 14pt+ bold). + +### 4.5 Support Display P3 Wide Gamut + +Use Display P3 color space for vibrant, accurate colors on modern iPhones. Define colors in the asset catalog with the Display P3 gamut. + +### 4.6 Background Hierarchy + +Layer backgrounds to create visual depth: + +```swift +// Level 1: Main view background +Color(.systemBackground) + +// Level 2: Cards, grouped sections +Color(.secondarySystemBackground) + +// Level 3: Nested elements within cards +Color(.tertiarySystemBackground) +``` + +### 4.7 One Accent Color for Interactive Elements + +Choose a single tint/accent color for all interactive elements (buttons, links, toggles). This creates a consistent, learnable visual language. + +```swift +@main +struct MyApp: App { + var body: some Scene { + WindowGroup { + ContentView() + .tint(.orange) + } + } +} +``` + +--- + +## 5. Accessibility + +**Impact:** CRITICAL + +### 5.1 VoiceOver Labels on All Interactive Elements + +Every button, control, and interactive element must have a meaningful accessibility label. + +```swift +Button(action: toggleFavorite) { + Image(systemName: isFavorite ? "heart.fill" : "heart") +} +.accessibilityLabel(isFavorite ? "Remove from favorites" : "Add to favorites") +``` + +### 5.2 Logical VoiceOver Navigation Order + +Ensure VoiceOver reads elements in a logical order. Use `.accessibilitySortPriority()` to adjust when the visual layout doesn't match the reading order. + +```swift +HStack { + Text("$49.99") + .accessibilitySortPriority(2) + Text("Premium Plan") + .accessibilitySortPriority(1) +} +``` + +### 5.3 Support Bold Text + +When the user enables Bold Text in Settings, SwiftUI text styles handle this automatically. Custom text must respond to `UIAccessibility.isBoldTextEnabled`. + +### 5.4 Support Reduce Motion + +Disable decorative animations and parallax when Reduce Motion is enabled. + +```swift +@Environment(\.accessibilityReduceMotion) private var reduceMotion + +var body: some View { + CardView() + .animation(reduceMotion ? nil : .spring(duration: 0.4), value: expanded) +} +``` + +### 5.5 Support Increase Contrast + +When the user enables Increase Contrast, ensure custom colors have higher-contrast variants. Use `@Environment(\.colorSchemeContrast)` to detect. + +### 5.6 Don't Convey Info Only by Color, Shape, or Position + +Information must be available through multiple channels. Pair visual indicators with text or accessibility descriptions. + +### 5.7 Alternative Interactions for All Gestures + +Every custom gesture must have an equivalent tap-based or menu-based alternative for users who cannot perform complex gestures. + +### 5.8 Support Switch Control and Full Keyboard Access + +Ensure all interactions work with Switch Control (external switches) and Full Keyboard Access (Bluetooth keyboards). Test navigation order and focus behavior. + +--- + +## 6. Gestures & Input + +**Impact:** HIGH + +### 6.1 Use Standard Gestures + +Stick to gestures users already know: + +- **Tap** — Select items, trigger buttons +- **Long press** — Show context menus, enter edit mode +- **Horizontal swipe** — List row actions (delete/archive), back navigation +- **Vertical swipe** — Scroll content, dismiss sheets +- **Pinch** — Scale images/maps +- **Rotate** — Adjust angle (photos, maps) + +### 6.2 Never Override System Gestures + +iOS reserves these edge gestures—do not intercept: + +- Left edge swipe → back navigation +- Top-left pull → Notification Center +- Top-right pull → Control Center +- Bottom edge swipe → home/app switcher + +### 6.3 Custom Gestures Must Be Discoverable + +If you add a custom gesture, provide visual hints (e.g., a grabber handle) and ensure the action is also available through a visible button or menu item. + +### 6.4 Support All Input Methods + +Design for touch first, but also support hardware keyboards, assistive devices (Switch Control, head tracking), and pointer input. + +--- + +## 7. Components + +**Impact:** HIGH + +### 7.1 Button Styles + +Use the built-in button styles appropriately: + +```swift +VStack(spacing: 16) { + Button("Checkout") { checkout() } + .buttonStyle(.borderedProminent) + + Button("Add to Wishlist") { addToWishlist() } + .buttonStyle(.bordered) + + Button("Remove Item", role: .destructive) { removeItem() } +} +``` + +### 7.2 Alerts — Critical Info Only + +Use alerts sparingly for critical information that requires a decision. Prefer 2 buttons; maximum 3. + +```swift +.alert("Discard Draft?", isPresented: $showDiscardAlert) { + Button("Discard", role: .destructive) { discardDraft() } + Button("Keep Editing", role: .cancel) { } +} message: { + Text("Your unsaved changes will be lost.") +} +``` + +### 7.3 Sheets for Scoped Tasks + +Present sheets for self-contained tasks. Always provide a way to dismiss (close button or swipe down). + +```swift +.sheet(isPresented: $showEditor) { + NavigationStack { + EditorView() + .navigationTitle("Edit Profile") + .toolbar { + ToolbarItem(placement: .cancellationAction) { + Button("Cancel") { showEditor = false } + } + ToolbarItem(placement: .confirmationAction) { + Button("Save") { saveProfile() } + } + } + } + .presentationDetents([.medium, .large]) + .presentationDragIndicator(.visible) +} +``` + +### 7.4 Lists — The Foundation of iOS Apps + +Most iOS apps are lists ("90% of mobile design is list design"). + +**List Styles:** +- `.insetGrouped` — Modern default (rounded corners, margins) +- `.grouped` — Traditional grouped sections +- `.plain` — Edge-to-edge rows +- `.sidebar` — Three-column iPad layout + +**Swipe Actions:** +- Leading swipe → Positive actions (mark read, archive) +- Trailing swipe → Destructive actions (delete at far right) +- Maximum 3-4 actions per side + +**Row Accessories:** +- Chevron → Indicates navigation +- Checkmark → Shows selection +- Detail button → Additional info without navigation + +```swift +List { + Section("Notifications") { + ForEach(notifications) { notification in + NotificationRow(notification: notification) + .swipeActions(edge: .trailing, allowsFullSwipe: true) { + Button(role: .destructive) { + delete(notification) + } label: { + Label("Delete", systemImage: "trash") + } + + Button { + markRead(notification) + } label: { + Label("Read", systemImage: "envelope.open") + } + .tint(.blue) + } + .swipeActions(edge: .leading) { + Button { + pin(notification) + } label: { + Label("Pin", systemImage: "pin") + } + .tint(.orange) + } + } + } +} +.listStyle(.insetGrouped) +``` + +### 7.5 Tab Bar Behavior + +- Use SF Symbols for tab icons — filled variant for the selected tab, outline for unselected +- Never hide the tab bar when navigating deeper within a tab +- Badge important counts with `.badge()` + +```swift +NotificationsView() + .tabItem { + Label("Notifications", systemImage: "bell") + } + .badge(unreadCount) +``` + +### 7.6 Search + +Place search using `.searchable()`. Provide search suggestions and support recent searches. + +```swift +NavigationStack { + List(searchResults) { item in + ItemRow(item: item) + } + .searchable(text: $query, prompt: "Search products") + .searchSuggestions { + ForEach(recentSearches, id: \.self) { term in + Text(term) + .searchCompletion(term) + } + } +} +``` + +### 7.7 Context Menus + +Use context menus (long press) for secondary actions. Never use a context menu as the only way to access an action. + +```swift +ImageThumbnail(image: image) + .contextMenu { + Button { shareImage(image) } label: { + Label("Share", systemImage: "square.and.arrow.up") + } + Button { copyImage(image) } label: { + Label("Copy", systemImage: "doc.on.doc") + } + Divider() + Button(role: .destructive) { deleteImage(image) } label: { + Label("Delete", systemImage: "trash") + } + } +``` + +### 7.8 Forms and Input + +**Text Fields:** +- 44pt minimum height +- Match keyboard type to input (`.emailAddress`, `.numberPad`, `.URL`) +- Clear button when text entered +- Placeholder uses `.quaternary` label color + +```swift +Form { + Section("Account") { + TextField("Email", text: $email) + .textContentType(.emailAddress) + .keyboardType(.emailAddress) + .autocapitalization(.none) + + SecureField("Password", text: $password) + .textContentType(.password) + } + + Section { + Button("Sign In") { signIn() } + .disabled(email.isEmpty || password.isEmpty) + } +} +``` + +**Pickers:** +- Inline → 3-7 options +- Menu → 2-5 options (iOS 14+) +- Wheel → Date/time or long lists + +### 7.9 Progress Indicators + +- Determinate `ProgressView(value:total:)` for operations with known duration +- Indeterminate `ProgressView()` for unknown duration +- Never block the entire screen with a spinner + +```swift +VStack { + ProgressView(value: uploadProgress, total: 1.0) + .progressViewStyle(.linear) + + Text("\(Int(uploadProgress * 100))% uploaded") + .font(.caption) + .foregroundStyle(.secondary) +} +``` + +--- + +## 8. Patterns + +**Impact:** MEDIUM + +### 8.1 Onboarding — Max 3 Pages, Skippable + +Keep onboarding to 3 or fewer pages. Always provide a skip option. Defer sign-in until the user needs authenticated features. + +```swift +TabView(selection: $currentPage) { + OnboardingPage(icon: "sparkles", title: "Smart Features", description: "...") + .tag(0) + OnboardingPage(icon: "bell.badge", title: "Stay Notified", description: "...") + .tag(1) + OnboardingPage(icon: "lock.shield", title: "Private & Secure", description: "...") + .tag(2) +} +.tabViewStyle(.page) +.overlay(alignment: .topTrailing) { + Button("Skip") { finishOnboarding() } + .padding() +} +``` + +### 8.2 Loading — Skeleton Views, No Blocking Spinners + +Use skeleton/placeholder views that match the layout of the content being loaded. Never show a full-screen blocking spinner. + +```swift +if isLoading { + ForEach(0..<5, id: \.self) { _ in + ArticleRowPlaceholder() + .redacted(reason: .placeholder) + } +} else { + ForEach(articles) { article in + ArticleRow(article: article) + } +} +``` + +### 8.3 Launch Screen — Match First Screen + +The launch storyboard must visually match the initial screen of the app. No splash logos, no branding screens. This creates the perception of instant launch. + +### 8.4 Modality — Use Sparingly + +Present modal views only when the user must complete or abandon a focused task. Always provide a clear dismiss action. Never stack modals on top of modals. + +### 8.5 Notifications — High Value Only + +Only send notifications for content the user genuinely cares about. Support actionable notifications. Categorize notifications so users can control them granularly. + +### 8.6 Settings Placement + +- Frequent settings: In-app settings screen accessible from a profile or gear icon +- Privacy/permission settings: Defer to the system Settings app via URL scheme +- Never duplicate system-level controls in-app + +### 8.7 Action Sheets + +For destructive or multiple-choice actions: + +```swift +.confirmationDialog("Delete Photo?", isPresented: $showDelete, titleVisibility: .visible) { + Button("Delete", role: .destructive) { deletePhoto() } + Button("Cancel", role: .cancel) { } +} message: { + Text("This action cannot be undone.") +} +``` + +- Destructive action at top (red) +- Cancel at bottom +- Dismiss by tapping outside + +### 8.8 Pull-to-Refresh + +Standard pattern for content updates: + +```swift +List(items) { item in + ItemRow(item: item) +} +.refreshable { + await loadNewItems() +} +``` + +### 8.9 Haptic Feedback + +Provide tactile response for significant actions: + +| Generator | Usage | +|-----------|-------| +| `UIImpactFeedbackGenerator` | Physical impacts (.light, .medium, .heavy) | +| `UINotificationFeedbackGenerator` | Success, warning, error | +| `UISelectionFeedbackGenerator` | Selection changes | + +```swift +Button("Complete") { + let feedback = UINotificationFeedbackGenerator() + feedback.notificationOccurred(.success) + markComplete() +} +``` + +--- + +## 9. Privacy & Permissions + +**Impact:** HIGH + +### 9.1 Request Permissions in Context + +Request a permission at the moment the user takes an action that needs it—never at app launch. + +```swift +Button("Take Photo") { + AVCaptureDevice.requestAccess(for: .video) { granted in + if granted { + showCamera = true + } + } +} +``` + +### 9.2 Explain Before System Prompt + +Show a custom explanation screen before triggering the system permission dialog. The system dialog only appears once—if the user denies, the app must direct them to Settings. + +```swift +struct LocationPermissionView: View { + var body: some View { + VStack(spacing: 20) { + Image(systemName: "location.fill") + .font(.system(size: 48)) + .foregroundStyle(.blue) + + Text("Find Nearby Places") + .font(.title2.bold()) + + Text("We use your location to show relevant results. Your location is never stored or shared.") + .multilineTextAlignment(.center) + .foregroundStyle(.secondary) + + Button("Enable Location") { + locationManager.requestWhenInUseAuthorization() + } + .buttonStyle(.borderedProminent) + + Button("Not Now") { dismiss() } + .foregroundStyle(.secondary) + } + .padding() + } +} +``` + +### 9.3 Support Sign in with Apple + +If the app offers any third-party sign-in (Google, Facebook), it must also offer Sign in with Apple. Present it as the first option. + +### 9.4 Don't Require Accounts Unless Necessary + +Let users explore the app before requiring sign-in. Gate only features that genuinely need authentication (purchases, sync, social features). + +### 9.5 App Tracking Transparency + +If you track users across apps or websites, display the ATT prompt. Respect denial—do not degrade the experience for users who opt out. + +### 9.6 Location Button for One-Time Access + +Use `LocationButton` for actions that need location once without requesting ongoing permission. + +```swift +LocationButton(.currentLocation) { + fetchNearbyResults() +} +.symbolVariant(.fill) +.labelStyle(.titleAndIcon) +``` + +--- + +## 10. System Integration + +**Impact:** MEDIUM + +### 10.1 Widgets for Glanceable Data + +Provide widgets using WidgetKit for information users check frequently. Widgets are not interactive (beyond tapping to open the app), so show the most useful snapshot. + +### 10.2 App Shortcuts for Key Actions + +Define App Shortcuts so users can trigger key actions from Siri, Spotlight, and the Shortcuts app. + +```swift +struct MyAppShortcuts: AppShortcutsProvider { + static var appShortcuts: [AppShortcut] { + AppShortcut( + intent: QuickAddIntent(), + phrases: ["Add item in \(.applicationName)"], + shortTitle: "Quick Add", + systemImageName: "plus.circle" + ) + } +} +``` + +### 10.3 Spotlight Indexing + +Index app content with `CSSearchableItem` so users

Navigation & Structure + +| Component | When to Use | +|-----------|-------------| +| `TabView` | 3-5 main app sections | +| `NavigationStack` | Hierarchical content drill-down | +| `.sheet` | Focused tasks requiring user completion | +| `.alert` | Decisions that block workflow | +| `.contextMenu` | Additional actions (always provide alternatives) | + +### Data Display + +| Component | When to Use | +|-----------|-------------| +| `List` | Scrollable rows with sections | +| `LazyVGrid` / `LazyHGrid` | Grid layouts | +| `.searchable` | Filterable content | +| `ProgressView` | Loading or task progress | + +### User Input + +| Component | When to Use | +|-----------|-------------| +| `TextField` | Single-line text | +| `TextEditor` | Multi-line text | +| `Picker` | Selection from options | +| `Toggle` | Binary on/off choice | +| `Stepper` | Numeric increment/decrement | + +### System Features + +| Component | When to Use | +|-----------|-------------| +| `ShareLink` | Content sharing | +| `LocationButton` | One-time location access | +| `PhotosPicker` | Image selection | +| `UIImpactFeedbackGenerator` | Tactile response | + +--- + +## Anti-Patterns + +Avoid these common HIG violations: + +| Pattern | Problem | Solution | +|---------|---------|----------| +| Hamburger/drawer menu | Hides navigation, users miss features | Use TabView with 3-5 tabs | +| Broken back swipe | Custom gestures block system navigation | Keep NavigationStack default behavior | +| Full-screen spinner | App feels frozen, no progress indication | Use skeleton views with `.redacted()` | +| Logo splash screen | Artificial delay, wastes user time | Match launch screen to first view | +| Permissions at launch | Users deny without context | Request when action requires it | +| Fixed font sizes | Breaks Dynamic Type, accessibility issues | Use `.font(.body)` semantic styles | +| Color-only status | Colorblind users miss information | Add icons or text labels | +| Alert overuse | Interrupts flow for minor info | Use inline messages or banners | +| Hidden tab bar | Users lose navigation context | Keep tab bar visible on push | +| Content in unsafe areas | Text hidden under notch/Dynamic Island | Only ignore safe area for backgrounds | +| No modal dismiss | Users trapped in view | Add cancel button and swipe dismiss | +| Gesture-only actions | Accessibility users blocked | Provide button/menu alternatives | +| Small tap targets | Frequent mis-taps | Minimum 44x44pt hit area | +| Nested modals | Navigation confusion | Use NavigationStack within single sheet | +| Hardcoded colors | Broken in Dark Mode | Use semantic colors or asset variants | + +--- + +## Review Checklist + +Code review checklist for SwiftUI apps: + +### Layout +- [ ] Interactive elements have 44pt minimum touch area +- [ ] Essential content stays within safe area bounds +- [ ] Main actions positioned for one-handed use (bottom) +- [ ] UI works across iPhone SE to Pro Max screen sizes +- [ ] Spacing uses 8pt increments + +### Navigation +- [ ] Main sections use bottom TabView (3-5 tabs) +- [ ] No drawer/hamburger navigation +- [ ] Root views show large navigation titles +- [ ] System back gesture not blocked +- [ ] Tab state persists when switching + +### Text & Fonts +- [ ] Text uses semantic styles (`.body`, `.headline`, etc.) +- [ ] Dynamic Type works at all sizes including accessibility +- [ ] Content reflows without truncation at large sizes +- [ ] No text below 11pt + +### Colors +- [ ] Uses `.primary`, `.secondary`, `Color(.systemBackground)` +- [ ] Custom colors have light/dark variants in assets +- [ ] Status indicators combine color with icon/text +- [ ] Text contrast ratio meets WCAG AA + +### Accessibility +- [ ] Icon buttons have `.accessibilityLabel()` +- [ ] VoiceOver order matches logical flow +- [ ] Animations respect `accessibilityReduceMotion` +- [ ] All actions have non-gesture alternatives + +### Modals & Alerts +- [ ] Alerts reserved for critical decisions only +- [ ] Sheets provide clear dismiss mechanism +- [ ] No stacked modal presentations + +### Permissions +- [ ] Permissions requested at point of use +- [ ] Pre-permission explanation screens used +- [ ] Core features work without sign-in + +--- + +## iPad Adaptation + +iPad users expect different interaction patterns: + +**Layout:** Use `NavigationSplitView` for master-detail: + +```swift +NavigationSplitView(columnVisibility: $columnVisibility) { + SidebarView() +} content: { + ListContentView() +} detail: { + DetailView() +} +.navigationSplitViewStyle(.balanced) +``` + +**Presentation:** Action sheets become popovers automatically, but you can force popover: + +```swift +.popover(isPresented: $showOptions) { + OptionsView() +} +``` + +**Keyboard:** Add shortcuts for power users: + +```swift +.keyboardShortcut("n", modifiers: .command) // Cmd+N +``` + +**Drag & Drop:** Enable cross-app data transfer: + +```swift +.draggable(item) +.dropDestination(for: Item.self) { items, location in + handleDrop(items) + return true +} +``` + +--- + +## Pre-Release Verification + +Run through these scenarios before shipping: + +**Visual consistency:** +- Switch between Light/Dark mode—does everything remain readable? +- Crank Dynamic Type to maximum—does layout adapt or break? +- Enable Bold Text—do custom fonts respond? + +**Interaction quality:** +- Can you complete every action using only VoiceOver? +- Do all buttons feel tappable on first try (no mis-taps)? +- Does back-swipe work everywhere in navigation? + +**Edge cases:** +- What happens on iPhone SE's small screen? +- What happens on iPad with keyboard attached? +- What shows when network fails mid-operation? +- What happens if user denies permissions? + +**Platform compliance:** +- Are you using SF Symbols instead of custom icon PNGs? +- Are all colors from semantic palette or asset catalog with variants? +- Do destructive actions require explicit confirmation? + +--- + +*SwiftUI, SF

build thoughtful, high-impact workflow tools +- Consolidate related operations (e.g., `schedule_event` that both checks availability and creates event) +- Focus on tools that enable complete tasks, not just individual API calls +- Consider what workflows agents actually need to accomplish + +**Optimize for Limited Context:** +- Agents have constrained context windows - make every token count +- Return high-signal information, not exhaustive data dumps +- Provide "concise" vs "detailed" response format options +- Default to human-readable identifiers over technical codes (names over IDs) +- Consider the agent's context budget as a scarce resource + +**Design Actionable Error Messages:** +- Error messages should guide agents toward correct usage patterns +- Suggest specific next steps: "Try using filter='active_only' to reduce results" +- Make errors educational, not just diagnostic +- Help agents learn proper tool usage through clear feedback + +**Follow Natural Task Subdivisions:** +- Tool names should reflect how humans think about tasks +- Group related tools with consistent prefixes for discoverability +- Design tools around natural workflows, not just API structure + +**Use Evaluation-Driven Development:** +- Create realistic evaluation scenarios early +- Let agent feedback drive tool improvements +- Prototype quickly and iterate based on actual agent performance + +#### 1.3 Study MCP Protocol Documentation + +**Fetch the latest MCP protocol documentation:** + +Use WebFetch to load: `https://modelcontextprotocol.io/llms-full.txt` + +This comprehensive document contains the complete MCP specification and guidelines. + +#### 1.4 Study Framework Documentation + +**Load and read the following reference files:** + +- **MCP Best Practices**: [📋 View Best Practices](./reference/mcp_best_practices.md) -

Should not instruct or require modifying state to arrive at the correct answer + +3. **Questions must be REALISTIC, CLEAR, CONCISE, and COMPLEX** + - Must require another LLM to use multiple (potentially dozens of) tools or steps to answer + +### Complexity and Depth + +4. **Questions must require deep exploration** + - Consider multi-hop questions requiring multiple sub-questions and sequential tool calls + - Each step should benefit from information found in previous questions + +5. **Questions may require extensive paging** + - May need paging through multiple pages of results + - May require querying old data (1-2 years out-of-date) to find niche information + - The questions must be DIFFICULT + +6. **Questions must require deep understanding** + - Rather than surface-level knowledge + - May pose complex ideas as True/False questions requiring evidence + - May use multiple-choice format where LLM must search different hypotheses + +7. **Questions must not be solvable with straightforward keyword search** + - Do not include specific keywords from the target content + - Use synonyms, related concepts, or paraphrases + - Require multiple searches, analyzing multiple related items, extracting context, then deriving the answer + +### Tool Testing + +8. **Questions should stress-test tool return values** + - May elicit tools returning large JSON objects or lists, overwhelming the LLM + - Should require understanding multiple modalities of data: + - IDs and names + - Timestamps and datetimes (months, days, years, seconds) + - File IDs, names, extensions, and mimetypes + - URLs, GIDs, etc. + - Should probe the tool's ability to return all useful forms of data + +9. **Questions should MOSTLY reflect real human use cases** + - The kinds of information retrieval tasks that HUMANS assisted by an LLM would care about + +10. **Questions may require dozens of tool calls** + - This challenges LLMs with limited context + - Encourages MCP server tools to reduce information returned + +11. **Include ambiguous questions** + - May be ambiguous OR require difficult decisions on which tools to call + - Force the LLM to potentially make mistakes or misinterpret + - Ensure that despite AMBIGUITY, there is STILL A SINGLE VERIFIABLE ANSWER + +### Stability + +12. **Questions must be designed so the answer DOES NOT CHANGE** + - Do not ask questions that rely on "current state" which is dynamic + - For example, do not count: + - Number of reactions to a post + - Number of replies to a thread + - Number of members in a channel + +13. **DO NOT let the MCP server RESTRICT the kinds of questions you create** + - Create challenging and complex questions + - Some may not be solvable with the available MCP server tools + - Questions may require specific output formats (datetime vs. epoch time, JSON vs. MARKDOWN) + - Questions may require dozens of tool calls to complete + +## Answer Guidelines + +### Verification + +1. **Answers must be VERIFIABLE via direct string comparison** + - If the answer can be re-written in many formats, clearly specify the output format in the QUESTION + - Examples: "Use YYYY/MM/DD.", "Respond True or False.", "Answer A, B, C, or D and nothing else." + - Answer should be a single VERIFIABLE value such as: + - User ID, user name, display name, first name, last name + - Channel ID, channel name + - Message ID, string + - URL, title + - Numerical quantity + - Timestamp, datetime + - Boolean (for True/False questions) + - Email address, phone number + - File ID, file name, file extension + - Multiple choice answer + - Answers must not require special formatting or complex, structured output + - Answer will be verified using DIRECT STRING COMPARISON + +### Readability + +2. **Answers should generally prefer HUMAN-READABLE formats** + - Examples: names, first name, last name, datetime, file name, message string, URL, yes/no, true/false, a/b/c/d + - Rather than opaque IDs (though IDs are acceptable) + - The VAST MAJORITY of answers should be human-readable + +### Stability + +3. **Answers must be STABLE/STATIONARY** + - Look at old content (e.g., conversations that have ended, projects that have launched, questions answered) + - Create QUESTIONS based on "closed" concepts that will always return the same answer + - Questions may ask to consider a fixed time window to insulate from non-stationary answers + - Rely on context UNLIKELY to change + - Example: if finding a paper name, be SPECIFIC enough so answer is not confused with papers published later + +4. **Answers must be CLEAR and UNAMBIGUOUS** + - Questions must be designed so there is a single, clear answer + - Answer can be derived from using the MCP server tools + +### Diversity + +5. **Answers must be DIVERSE** + - Answer should be a single VERIFIABLE value in diverse modalities and formats + - User concept: user ID, user name, display name, first name, last name, email address, phone number + - Channel concept: channel ID, channel name, channel topic + - Message concept: message ID, message string, timestamp, month, day, year + +6. **Answers must NOT be complex structures** + - Not a list of values + - Not a complex object + - Not a list of IDs or strings + - Not natural language text + - UNLESS the answer can be straightforwardly verified using DIRECT STRING COMPARISON + - And can be realistically reproduced + - It should be unlikely that an LLM would return the same list in any other order or format + +## Evaluation Process + +### Step 1: Documentation Inspection + +Read the documentation of the target API to understand: +- Available endpoints and functionality +- If ambiguity exists, fetch additional information from the web +- Parallelize this step AS MUCH AS POSSIBLE +- Ensure each subagent is ONLY examining documentation from the file system or on the web + +### Step 2: Tool Inspection + +List the tools available in the MCP server: +- Inspect the MCP server directly +- Understand input/output schemas, docstrings, and descriptions +- WITHOUT calling the tools themselves at this stage + +### Step 3: Developing Understanding + +Repeat steps 1 & 2 until you have a good understanding: +- Iterate multiple times +- Think about the kinds of tasks you want to create +- Refine your understanding +- At NO stage should you READ the code of the MCP server implementation itself +- Use your intuition and understanding to create reasonable, realistic, but VERY challenging tasks + +### Step 4: Read-Only Content Inspection + +After understanding the API and tools, USE the MCP server tools: +- Inspect content using READ-ONLY and NON-DESTRUCTIVE operations ONLY +- Goal: identify specific content (e.g., users, channels, messages, projects, tasks) for creating realistic questions +- Should NOT call any tools that modify state +- Will NOT read the code of the MCP server implementation itself +- Parallelize this step with individual sub-agents pursuing independent explorations +- Ensure each subagent is only performing READ-ONLY, NON-DESTRUCTIVE, and IDEMPOTENT operations +- BE CAREFUL: SOME TOOLS may return LOTS OF DATA which would cause you to run out of CONTEXT +- Make INCREMENTAL, SMALL, AND TARGETED tool calls for exploration +- In all tool call requests, use the `limit` parameter to limit results (<10) +- Use pagination + +### Step 5: Task Generation + +After inspecting the content, create 10 human-readable questions: +- An LLM should be able to answer these with the MCP server +- Follow all question and answer guidelines above + +## Output Format + +Each QA pair consists of a question and an answer.

Pagination Best Practices + +For tools that list resources: + +- **Always respect the `limit` parameter**: Never load all results when a limit is specified +- **Implement pagination**: Use `offset` or cursor-based pagination +- **Return pagination metadata**: Include `has_more`, `next_offset`/`next_cursor`, `total_count` +- **Never load all results into memory**: Especially important for large datasets +- **Default to reasonable limits**: 20-50 items is typical +- **Include clear pagination info in responses**: Make it easy for LLMs to request more data + +Example pagination response structure: +```json +{ + "total": 150, + "count": 20, + "offset": 0, + "items": [...], + "has_more": true, + "next_offset": 20 +} +``` + +--- + +## 5. Character Limits and Truncation + +To prevent overwhelming responses with too much data: + +- **Define CHARACTER_LIMIT constant**: Typically 25,000 characters at module level +- **Check response size before returning**: Measure the final response length +- **Truncate gracefully with clear indicators**: Let the LLM know data was truncated +- **Provide guidance on filtering**: Suggest how to use parameters to reduce results +- **Include truncation metadata**: Show what was truncated and how to get more + +Example truncation handling: +```python +CHARACTER_LIMIT = 25000 + +if len(result) > CHARACTER_LIMIT: + truncated_data = data[:max(1, len(data) // 2)] + response["truncated"] = True + response["truncation_message"] = ( + f"Response truncated from {len(data)} to {len(truncated_data)} items. " + f"Use 'offset' parameter or add filters to see more results." + ) +``` + +--- + +## 6.

Through tools, LLMs can interact with external systems, perform computations, and take actions in the real world. + + + Tools are designed to be **model-controlled**, meaning that tools are exposed from servers to clients with the intention of the AI model being able to automatically invoke them (with a human in the loop to grant approval). + + +## Overview + +Tools in MCP allow servers to expose executable functions that can be invoked by clients and used by LLMs to perform actions. Key aspects of tools include: + +* **Discovery**: Clients can obtain a list of available tools by sending a `tools/list` request +* **Invocation**: Tools are called using the `tools/call` request, where servers perform the requested operation and return results +* **Flexibility**: Tools can range from simple calculations to complex API interactions + +Like [resources](/docs/concepts/resources), tools are identified by unique names and can include descriptions to guide their usage. However, unlike resources, tools represent dynamic operations that can modify state or interact with external systems. + +## Tool definition structure + +Each tool is defined with the following structure: + +```typescript +{ + name: string; // Unique identifier for the tool + description?: string; // Human-readable description + inputSchema: { // JSON Schema for the tool's parameters + type: "object", + properties: { ... } // Tool-specific parameters + }, + annotations?: { // Optional hints about tool behavior + title?: string; // Human-readable title for the tool + readOnlyHint?: boolean; // If true, the tool does not modify its environment + destructiveHint?: boolean; // If true, the tool may perform destructive updates + idempotentHint?: boolean; // If true, repeated calls with same args have no additional effect + openWorldHint?: boolean; // If true, tool interacts with external entities + } +} +``` + +## Implementing tools + +Here's an example of implementing a basic tool in an MCP server: + + + + ```typescript + const server = new Server({ + name: "example-server", + version: "1.0.0" + }, { + capabilities: { + tools: {} + } + }); + + // Define available tools + server.setRequestHandler(ListToolsRequestSchema, async () => { + return { + tools: [{ + name: "calculate_sum", + description: "Add two numbers together", + inputSchema: { + type: "object", + properties: { + a: { type: "number" }, + b: { type: "number" } + }, + required: ["a", "b"] + } + }] + }; + }); + + // Handle tool execution + server.setRequestHandler(CallToolRequestSchema, async (request) => { + if (request.params.name === "calculate_sum") { + const { a, b } = request.params.arguments; + return { + content: [ + { + type: "text", + text: String(a + b) + } + ] + }; + } + throw new Error("Tool not found"); + }); + ``` + + + + ```python + app = Server("example-server") + + @app.list_tools() + async def list_tools() -> list[types.Tool]: + return [ + types.Tool( + name="calculate_sum", + description="Add two numbers together", + inputSchema={ + "type": "object", + "properties": { + "a": {"type": "number"}, + "b": {"type": "number"} + }, + "required": ["a", "b"] + } + ) + ] + + @app.call_tool() + async def call_tool( + name: str, + arguments: dict + ) -> list[types.TextContent | types.ImageContent | types.EmbeddedResource]: + if name == "calculate_sum": + a = arguments["a"] + b = arguments["b"] + result = a + b + return [types.TextContent(type="text", text=str(result))] + raise ValueError(f"Tool not found: {name}") + ``` + + + +## Example tool patterns + +Here are some examples of types of tools that a server could provide: + +### System operations + +Tools that interact with the local system: + +```typescript +{ + name: "execute_command", + description: "Run a shell command", + inputSchema: { + type: "object", + properties: { + command: { type: "string" }, + args: { type: "array", items: { type: "string" } } + } + } +} +``` + +### API integrations + +Tools that wrap external APIs: + +```typescript +{ + name: "github_create_issue", + description: "Create a GitHub issue", + inputSchema: { + type: "object", + properties: { + title: { type: "string" }, + body: { type: "string" }, + labels: { type: "array", items: { type: "string" } } + } + } +} +``` + +### Data processing + +Tools that transform or analyze data: + +```typescript +{ + name: "analyze_csv", + description: "Analyze a CSV file", + inputSchema: { + type: "object", + properties: { + filepath: { type: "string" }, + operations: { + type: "array", + items: { + enum: ["sum", "average", "count"] + } + } + } + } +} +``` + +## Best practices + +When implementing tools: + +1. Provide clear, descriptive names and descriptions +2. Use detailed JSON Schema definitions for parameters +3. Include examples in tool descriptions to demonstrate how the model should use them +4. Implement proper error handling and validation +5. Use progress reporting for long operations +6. Keep tool operations focused and atomic +7. Document expected return value structures +8. Implement proper timeouts +9. Consider rate limiting for resource-intensive operations +10. Log tool usage for debugging and monitoring + +### Tool name conflicts + +MCP client applications and MCP server proxies may encounter tool name conflicts when building their own tool lists. For example, two connected MCP servers `web1` and `web2` may both expose a tool named `search_web`. + +Applications may disambiguiate tools with one of the following strategies (among others; not an exhaustive list): + +* Concatenating a unique, user-defined server name with the tool name, e.g. `web1___search_web` and `web2___search_web`. This strategy may be preferable when unique server names are already provided by the user in a configuration file. +* Generating a random prefix for the tool name, e.g. `jrwxs___search_web` and `6cq52___search_web`. This strategy may be preferable in server proxies where user-defined unique names are not available. +* Using the server URI as a prefix for the tool name, e.g. `web1.example.com:search_web` and `web2.example.com:search_web`. This strategy may be suitable when working with remote MCP servers. + +Note that the server-provided name from the initialization flow is not guaranteed to be unique and is not generally suitable for disambiguation purposes. + +## Security considerations + +When exposing tools: + +### Input validation + +* Validate all parameters against the schema +* Sanitize file paths and system commands +* Validate URLs and external identifiers +* Check parameter sizes and ranges +* Prevent command injection + +### Access control + +* Implement authentication where needed +* Use appropriate authorization checks +* Audit tool usage +* Rate limit requests +* Monitor for abuse + +### Error handling + +* Don't expose internal errors to clients +* Log security-relevant errors +* Handle timeouts appropriately +* Clean up resources after errors +* Validate return values + +## Tool discovery and updates + +MCP supports dynamic tool discovery: + +1. Clients can list available tools at any time +2. Servers can notify clients when tools change using `notifications/tools/list_changed` +3. Tools can be added or removed during runtime +4. Tool definitions can be updated (though this should be done carefully) + +## Error handling + +Tool errors should be reported within the result object, not as MCP protocol-level errors. This allows the LLM to see and potentially handle the error. When a tool encounters an error: + +1. Set `isError` to `true` in the result +2. Include error details in the `content` array + +Here's an example of proper error handling for tools: + + + + ```typescript + try { + // Tool operation + const result = performOperation(); + return { + content: [ + { + type: "text", + text: `Operation successful: ${result}` + } + ] + }; + } catch (error) { + return { + isError: true, + content: [ + { + type: "text", + text: `Error: ${error.message}` + } + ] + }; + } + ``` + + + + ```python + try: + # Tool operation + result = perform_operation() + return types.CallToolResult( + content=[ + types.TextContent( + type="text", + text=f"Operation successful: {result}" + ) + ] + ) + except Exception as error: + return types.CallToolResult( + isError=True, + content=[ + types.TextContent( + type="text", + text=f"Error: {str(error)}" + ) + ] + ) + ``` + + + +This approach allows the LLM to see that an error occurred and potentially take corrective action or request human intervention. + +## Tool annotations + +Tool annotations provide additional metadata about a tool's behavior, helping clients understand how to present and manage tools. These annotations are hints that describe the nature and impact of a tool, but should not be relied upon for security decisions. + +### Purpose of tool annotations + +Tool annotations serve several key purposes: + +1. Provide UX-specific information without affecting model context +2. Help clients categorize and present tools appropriately +3. Convey information about a tool's potential side effects +4. Assist in developing intuitive interfaces for tool approval + +### Available tool annotations + +The MCP specification defines the following annotations for tools: + +| Annotation | Type | Default | Description | +| ----------------- | ------- | ------- | ------------------------------------------------------------------------------------------------------------------------------------ | +| `title` | string | - | A human-readable title for the tool, useful for UI display | +| `readOnlyHint` | boolean | false | If true, indicates the tool does not modify its environment | +| `destructiveHint` | boolean | true | If true, the tool may perform destructive updates (only meaningful when `readOnlyHint` is false) | +| `idempotentHint` | boolean | false | If true, calling the tool repeatedly with the same arguments has no additional effect (only meaningful when `readOnlyHint` is false) | +| `openWorldHint` | boolean | true | If true, the tool may interact with an "open world" of external entities | + +### Example usage + +Here's how to define tools with annotations for different scenarios: + +```typescript +// A read-only search tool +{ + name: "web_search", + description: "Search the web for information", + inputSchema: { + type: "object", + properties: { + query: { type: "string" } + }, + required: ["query"] + }, + annotations: { + title: "Web Search", + readOnlyHint: true, + openWorldHint: true + } +} + +// A destructive file deletion tool +{ + name: "delete_file", + description: "Delete a file from the filesystem", + inputSchema: { + type: "object", + properties: { + path: { type: "string" } + }, + required: ["path"] + }, + annotations: { + title: "Delete File", + readOnlyHint: false, + destructiveHint: true, + idempotentHint: true, + openWorldHint: false + } +} + +// A non-destructive database record creation tool +{ + name: "create_record", + description: "Create a new record in the database", + inputSchema: { + type: "object", + properties: { + table: { type: "string" }, + data: { type: "object" } + }, + required: ["table", "data"] + }, + annotations: { + title: "Create Database Record", + readOnlyHint: false, + destructiveHint: false, + idempotentHint: false, + openWorldHint: false + } +} +``` + +### Integrating annotations in server implementation + + + + ```typescript + server.setRequestHandler(ListToolsRequestSchema, async () => { + return { + tools: [{ + name: "calculate_sum", + description: "Add two numbers together", + inputSchema: { + type: "object", + properties: { + a: { type: "number" }, + b: { type: "number" } + }, + required: ["a", "b"] + }, + annotations: { + title: "Calculate Sum", + readOnlyHint: true, + openWorldHint: false + } + }] + }; + }); + ``` + + + + ```python + from mcp.server.fastmcp import FastMCP + + mcp = FastMCP("example-server") + + @mcp.tool( + annotations={ + "title": "Calculate Sum", + "readOnlyHint": True, + "openWorldHint": False + } + ) + async def calculate_sum(a: float, b: float) -> str: + """Add two numbers together. + + Args: + a: First number to add + b: Second number to add + """ + result = a + b + return str(result) + ``` + + + +### Best practices for tool annotations + +1. **Be accurate about side effects**: Clearly indicate whether a tool modifies its environment and whether those modifications are destructive. + +2. **Use descriptive titles**: Provide human-friendly titles that clearly describe the tool's purpose. + +3. **Indicate idempotency properly**: Mark tools as idempotent only if repeated calls with the same arguments truly have no additional effect. + +4. **Set appropriate open/closed world hints**: Indicate whether a tool interacts with a closed system (like a database) or an open system (like the web). + +5. **Remember annotations are hints**: All properties in ToolAnnotations are hints and not guaranteed to provide a faithful description of tool behavior.

Use this scaffold: + +```csharp +// File: scripts/dotnet/task.csx (or a new .cs in a Console project) +// dotnet run --project scripts/dotnet/MiniMaxAIDocx.Cli -- run-script task.csx +#r "nuget: DocumentFormat.OpenXml, 3.2.0" + +using DocumentFormat.OpenXml; +using DocumentFormat.OpenXml.Packaging; +using DocumentFormat.OpenXml.Wordprocessing; + +using var doc = WordprocessingDocument.Create("output.docx", WordprocessingDocumentType.Document); +var mainPart = doc.AddMainDocumentPart(); +mainPart.Document = new Document(new Body()); + +// --- Your logic here --- +// Read the relevant Samples/*.cs file FIRST for tested patterns. +// See Samples/ table in References section below. +``` + +**Before writing any C#, read the relevant `Samples/*.cs` file** — they contain compilable, SDK-version-verified patterns.

Pick an aesthetic recipe from `Samples/AestheticRecipeSamples.cs` that matches the document type — do not invent formatting values. For CJK, also read `references/cjk_typography.md`. + +**Choose your path:** +- **Simple** (plain text, minimal formatting): use CLI — `$CLI create --type report --output out.docx --config content.json` +- **Structural** (custom styles, multi-section, TOC, images, complex tables): write C# directly. Read the relevant `Samples/*.cs` first. + +CLI options: `--type` (report|letter|memo|academic), `--title`, `--author`, `--page-size` (letter|a4|legal|a3), `--margins` (standard|narrow|wide), `--header`, `--footer`, `--page-numbers`, `--toc`, `--content-json`. + +Then run the **validation pipeline** (below). + +## Scenario B: Edit / Fill + +Read `references/scenario_b_edit_content.md` first. Preview → analyze → edit → validate. + +**Choose your path:** +- **Simple** (text replacement, placeholder fill): use CLI subcommands. +- **Structural** (add/reorganize sections, modify styles, manipulate tables, insert images): write C# directly. Read `references/openxml_element_order.md` and the relevant `Samples/*.cs`. + +Available CLI edit subcommands: +- `replace-text --find "X" --replace "Y"` +- `fill-placeholders --data '{"key":"value"}'` +- `fill-table --data table.json` +- `insert-section`, `remove-section`, `update-header-footer` + +```bash +$CLI edit replace-text --input in.docx --output out.docx --find "OLD" --replace "NEW" +$CLI edit fill-placeholders --input in.docx --output out.docx --data '{"name":"John"}' +``` + +Then run the **validation pipeline**. Also run diff to verify minimal changes: +```bash +$CLI diff --before in.docx --after out.docx +``` + +## Scenario C: Apply Template + +Read `references/scenario_c_apply_template.md` first. Preview and analyze both source and template. + +```bash +$CLI apply-template --input source.docx --template template.docx --output out.docx +``` + +For complex template operations (multi-template merge, per-section headers/footers, style merging), write C# directly — see Critical Rules below for required patterns. + +Run the **validation pipeline**, then the **hard gate-check**: +```bash +$CLI validate --input out.docx --gate-check assets/xsd/business-rules.xsd +``` +Gate-check is a **hard requirement**. Do NOT deliver until it passes. If it fails: diagnose, fix, re-run. + +Also diff to verify content preservation: `$CLI diff --before source.docx --after out.docx` + +## Validation pipeline + +Run after every write operation. For Scenario C the full pipeline is **mandatory**; for A/B it is **recommended** (skip only if the operation was trivially simple). + +```bash +$CLI merge-runs --input doc.docx # 1. consolidate runs +$CLI validate --input doc.docx --xsd assets/xsd/wml-subset.xsd # 2.

Always strip direct formatting — keep only `pStyle` reference and `t` text. Clean tables too (including `pPr/rPr` inside cells). + +**Track changes:** `` uses ``, never ``. `` uses ``, never ``. + +**Font size:** `w:sz` = points × 2 (12pt → `sz="24"`). Margins/spacing in DXA (1 inch = 1440, 1cm ≈ 567). + +**Heading styles MUST have OutlineLevel:** When defining heading styles (Heading1, ThesisH1, etc.), always include `new OutlineLevel { Val = N }` in `StyleParagraphProperties` (H1→0, H2→1, H3→2). Without this, Word sees them as plain styled text — TOC and navigation pane won't work. + +**Multi-template merge:** When given multiple template files (font, heading, breaks), read `references/scenario_c_apply_template.md` section "Multi-Template Merge" FIRST. Key rules: +- Merge styles from all templates into one styles.xml. Structure (sections/breaks) comes from the breaks template. +- Each content paragraph must appear exactly ONCE — never duplicate when inserting section breaks. +- NEVER insert empty/blank paragraphs as padding or section separators. Output paragraph count must equal input. Use section break properties (`w:sectPr` inside `w:pPr`) and style spacing (`w:spacing` before/after) for visual separation. +- Insert oddPage section breaks before EVERY chapter heading, not just the first. Even if a chapter has dual-column content, it MUST start with oddPage; use a second continuous break after the heading for column switching. +- Dual-column chapters need THREE section breaks: (1) oddPage in preceding para's pPr, (2) continuous+cols=2 in the chapter HEADING's pPr, (3) continuous+cols=1 in the last body para's pPr to revert. +- Copy `titlePg` settings from the breaks template for EACH section. Abstract and TOC sections typically need `titlePg=true`. + +**Multi-section headers/footers:** Templates with 10+ sections (e.g., Chinese thesis) have DIFFERENT headers/footers per section (Roman vs Arabic page numbers, different header text per zone). Rules: +- Use C-2 Base-Replace: copy the TEMPLATE as output base, then replace body content. This preserves all sections, headers, footers, and titlePg settings automatically. +- NEVER recreate headers/footers from scratch — copy template header/footer XML byte-for-byte. +- NEVER add formatting (borders, alignment, font size) not present in the template header XML. +- Non-cover sections MUST have header/footer XML files (at least empty header + page number footer). +- See `references/scenario_c_apply_template.md` section "Multi-Section Header/Footer Transfer". + +## References + +Load as needed — don't load all at once. Pick the most relevant files for the task. + +**The C# samples and design references below are the project's knowledge base ("encyclopedia").** When writing OpenXML code, ALWAYS read the relevant sample file first — it contains compilable, SDK-version-verified patterns that prevent common errors. When making aesthetic decisions, read the design principles and recipe files — they encode tested, harmonious parameter sets from authoritative sources (IEEE, ACM, APA, Nature, etc.), not guesses. +

Using Italic for Chinese Emphasis + +**BAD: Italic applied to Chinese text** +```xml + + + + + +``` +CJK glyphs have no true italic form. The renderer applies a synthetic slant that looks broken and ugly — characters appear to lean awkwardly. + +**GOOD: Use bold or emphasis dots (着重号) for Chinese emphasis** +```xml + + + + + + + + + + + + + +``` +**Why better:** Chinese typography has its own emphasis traditions. Bold and emphasis dots are native CJK conventions; italic is a Latin-script concept that does not translate. + +--- + +### 9b.

[Visual Hierarchy & Flow](#6-visual-hierarchy--flow) + +--- + +## 1. White Space & Breathing Room + +### Why It Works + +The human eye does not read continuously. It jumps in saccades, fixating on +small clusters of words. White space provides landing zones for these fixations +and gives the reader's peripheral vision a "frame" that makes each text block +feel manageable. When a page is packed to the edges, every glance returns more +text than working memory can buffer, triggering fatigue and avoidance. + +Research on content density consistently shows: + +- **60-70% content coverage** feels comfortable and professional. +- **80%+** starts to feel dense and bureaucratic. +- **90%+** feels oppressive -- the reader unconsciously rushes or skips. +- **Below 50%** feels wasteful or pretentious (unless intentional, like poetry). + +Wider margins also carry cultural signals. Academic and luxury documents use +generous margins (1.25-1.5 inches). Internal memos and drafts use narrower +margins (0.75-1.0 inches). The margin width tells the reader how much care +went into the document before they read a single word. + +Line spacing has a direct physiological basis: the eye must track back to the +start of the next line after each line break. If lines are too close, the eye +"slips" to the wrong line. If too far apart, the eye loses its sense of +continuity. The sweet spot is 120-145% of the font size. + +**Rule of thumb: when in doubt, add more space, not less.** + +### Good Example + +``` +Margins: 1 inch (1440 twips) all sides for business documents. +Line spacing: 1.15 (276 twips at 240 twips-per-line = 115%). +Paragraph spacing after: 8pt (160 twips) between body paragraphs. +``` + +```xml + + + + + + + +``` + +This produces a page where content occupies roughly 65% of the area. The +reader sees clear top/bottom breathing room, and paragraphs are distinct +without feeling disconnected. + +``` + Page layout (good): + +----------------------------------+ + | 1" margin | + | +------------------------+ | + | | Heading | | + | | | | + | | Body text here with | | + | | comfortable spacing | | + | | between lines. | | + | | | | <- visible gap between paragraphs + | | Another paragraph of | | + | | body text follows. | | + | | | | + | +------------------------+ | + | 1" margin | + +----------------------------------+ +``` + +### Bad Example + +```xml + + + + + + + +``` + +This fills ~85% of the page. Text runs edge-to-edge with no visual rest stops. +The reader sees a wall of text. + +``` + Page layout (bad): + +----------------------------------+ + | Heading | + | Body text crammed right up to | + | the margins with no spacing | + | between lines or paragraphs. | + | Another paragraph starts here | + | and the reader cannot tell where | + | one idea ends and another begins | + | because everything blurs into a | + | single dense block of text. | + +----------------------------------+ +``` + +### Quick Test + +1. Zoom out to 50% in your document viewer. If you cannot see clear "channels" + of white between text blocks, the spacing is too tight. +2. Print a test page. Hold it at arm's length. The text area should look like + a rectangle floating in white, not filling the page. +3. Check: is the line spacing value at least 264 (`w:line` for 1.1x) for body + text? If it is 240 (single), it is too tight for anything over 10pt. + +--- + +## 2. Contrast & Scale + +### Why It Works + +The brain processes visual hierarchy through relative difference, not absolute +size. A 20pt heading above 11pt body text creates a clear "this is important" +signal. But if every heading is 20pt and every sub-heading is 19pt, the brain +cannot distinguish them -- they merge into the same level. + +The key insight is **modular scale**: font sizes that grow by a consistent +ratio. This mirrors natural proportions and feels harmonious for the same +reason musical intervals do. + +Common scales and their character: + +| Ratio | Name | Character | Example progression (from 11pt) | +|-------|----------------|---------------------------------|---------------------------------| +| 1.200 | Minor third | Subtle, refined | 11 → 13.2 → 15.8 → 19.0 | +| 1.250 | Major third | Balanced, professional | 11 → 13.75 → 17.2 → 21.5 | +| 1.333 | Perfect fourth | Strong, authoritative | 11 → 14.7 → 19.5 → 26.0 | +| 1.414 | Augmented 4th | Dramatic, presentation-style | 11 → 15.6 → 22.0 → 31.1 | + +For most business documents, 1.25 (major third) works best: + +``` +Body = 11pt (w:sz="22") +H3 = 13pt (w:sz="26") -- 11 * 1.25 ≈ 13.75, round to 13 +H2 = 16pt (w:sz="32") -- 13 * 1.25 ≈ 16.25, round to 16 +H1 = 20pt (w:sz="40") -- 16 * 1.25 = 20 +``` + +Beyond size, **weight contrast** creates hierarchy without consuming vertical +space. Regular (400) vs Bold (700) is visible at any size. Semi-bold (600) vs +Regular is subtle and best avoided unless you also vary size or color. + +**Color contrast** adds a third dimension. Dark blue headings (#1F3864) against +softer dark gray body text (#333333) signals "heading" without needing a huge +size jump. Pure black (#000000) body text is harsher than necessary on white +backgrounds -- #333333 or #2D2D2D reduces glare without losing legibility. + +### Good Example + +```xml + + + + + + + + + + + + + + + + + + + + + + + + + + +``` + +``` + Visual hierarchy (good): + + [████████████████████] <- H1: 20pt bold navy (clearly dominant) + (generous space) + [██████████████] <- H2: 16pt bold navy (distinct step down) + (moderate space) + [████████████] <- H3: 13pt bold navy (smaller but still bold) + [░░░░░░░░░░░░░░░░░░░░░░] <- Body: 11pt regular gray + [░░░░░░░░░░░░░░░░░░░░░░] + [░░░░░░░░░░░░░░░░░░░░░░] +``` + +Each level is visually distinct from its neighbors. You can identify the +hierarchy even in peripheral vision. + +### Bad Example + +```xml + + + + + + + + + + + + + + + + + + + + + + + + + + +``` + +Problems: +- H3 (12pt bold) and body (12pt regular) differ only by weight -- too subtle. +- H1 (14pt) to H2 (13pt) is a 1pt step -- invisible at reading distance. +- Everything is pure black so color provides no differentiating signal. +- The ratio between levels is ~1.07, far too flat. + +### Quick Test + +1. **The squint test**: blur your eyes or step back from the screen. Can you + count the number of heading levels? If two levels merge, their contrast + is insufficient. +2. **Ratio check**: divide each heading size by the next smaller size. If any + ratio is below 1.15, the levels will look too similar. +3. **Color check**: do headings look distinct from body text when you glance + at the page? If everything is the same color, you are relying solely on + size/weight, which limits your hierarchy to ~3 effective levels. + +--- + +## 3. Proximity & Grouping + +### Why It Works + +The Gestalt principle of proximity: items that are close together are perceived +as belonging to the same group. In document typography, this means a heading +must be **closer to the content it introduces** than to the content above it. + +If a heading sits equidistant between two paragraphs, it looks orphaned -- the +reader's eye does not know if it belongs to the text above or below. The fix +is asymmetric spacing: **large space before the heading, small space after**. + +The recommended ratio is 2:1 or 3:1 (space-before : space-after). + +This same principle applies to: +- **List items**: spacing between items should be less than spacing between + paragraphs. Items in a list are a group and should visually cluster. +- **Captions**: a figure caption should be close to its figure, not floating + in the middle between the figure and the next paragraph. +- **Table titles**: the title sits close above the table, with more space + separating the title from preceding text. + +### Good Example + +```xml + + + + + + + + + + + + + + + + +``` + +``` + Proximity (good): + + ...end of previous section text. + <- 18pt gap (w:before="360") + ## Section Heading + <- 6pt gap (w:after="120") + First paragraph of new section + continues here with content. + <- 8pt gap (w:after="160") + Second paragraph follows. + + The heading clearly "belongs to" the text below it. +``` + +``` + List grouping (good): + + Consider these factors: + - First item <- 2pt gap between items + - Second item <- items cluster as a group + - Third item + <- 8pt gap after list + The next paragraph starts here. +``` + +### Bad Example + +```xml + + + + + + + + + + + +``` + +``` + Proximity (bad): + + ...end of previous section text. + <- 12pt gap + ## Section Heading + <- 12pt gap (same!) + First paragraph of new section. + + The heading floats between sections. It is unclear what it belongs to. +``` + +``` + List grouping (bad): + + Consider these factors: + <- 10pt gap + - First item + <- 10pt gap (same as paragraphs) + - Second item + <- 10pt gap + - Third item + <- 10pt gap + Next paragraph. + + The list does not feel like a group. Each item looks like a + separate paragraph that happens to have a bullet. +``` + +### Quick Test + +1. **Cover test**: cover the heading text. Looking only at the whitespace, + can you tell which block of text the heading belongs to? If the gaps above + and below are equal, the answer is "no." +2. **Number check**: `w:before` on headings should be at least 2x `w:after`. + Common good values: before=360 / after=120, or before=240 / after=80. +3. **List check**: `w:after` on list items should be less than half of + `w:after` on body paragraphs. If body uses 160, list items should use + 40-60. + +--- + +## 4. Alignment & Grid + +### Why It Works + +Alignment creates invisible lines that the eye follows down the page. When +elements share the same left edge, the reader perceives order and intention. +When elements are slightly misaligned (off by a few twips), the page looks +sloppy even if the reader cannot consciously identify why. + +**Left-align vs Justify:** + +- **Left-aligned** (ragged right) is best for English and other Latin-script + languages. The uneven right edge actually helps reading because each line + has a unique silhouette, making it easier for the eye to find the next line. + Justified text forces uneven word spacing that creates distracting "rivers" + of white running vertically through paragraphs. + +- **Justified** is best for CJK text. Chinese, Japanese, and Korean characters + are monospaced by design -- each occupies the same cell in an invisible grid. + Justification preserves this grid perfectly. Ragged right in CJK text breaks + the grid and looks untidy. + +**Indentation rule:** Use first-line indent OR paragraph spacing to separate +paragraphs -- never both. They serve the same purpose (marking paragraph +boundaries). Using both wastes space and creates visual stutter. + +- Western convention: paragraph spacing (no indent) is more modern. +- CJK convention: first-line indent of 2 characters is standard. +- Academic convention: first-line indent of 0.5 inch is traditional. + +### Good Example + +```xml + + + + + + + + + + + + + + + + + + + + + +``` + +``` + English paragraph separation (good -- spacing, no indent): + + This is the first paragraph with some text + that wraps to a second line naturally. + + This is the second paragraph. The gap above + clearly marks the boundary. + + + CJK paragraph separation (good -- indent, no spacing): + + 　　第一段正文内容从这里开始，使用两个字符 + 的首行缩进来标记段落边界。 + 　　第二段紧跟其后，没有段间距，但首行缩进 + 清晰地标识了新段落的开始。 +``` + +### Bad Example + +```xml + + + + + + + + + + + + + +``` + +Problems: +- Justified English text with narrow columns creates uneven word gaps. +- Using both first-line indent AND paragraph spacing is redundant. +- Left-aligned CJK breaks the character grid that CJK readers expect. +- CJK with spacing-based separation looks like translated western layout. + +### Quick Test + +1. **River test**: in justified English text, squint and look for vertical + white streaks running through the paragraph. If you see them, switch to + left-align or increase the column width. +2. **Double signal check**: does the document use BOTH first-line indent AND + paragraph spacing? If yes, remove one. Choose indent for CJK/academic, + spacing for modern western. +3. **Tab alignment**: if you use tabs for columns, do all tab stops across + the document use the same positions? Inconsistent tab stops create jagged + invisible grid lines. + +--- + +## 5. Repetition & Consistency + +### Why It Works + +Consistency is a trust signal. When a reader sees that every H2 looks the same, +every table follows the same pattern, and every page number sits in the same +spot, they unconsciously trust that the document was crafted with care. A single +inconsistency -- one H2 that is 15pt instead of 14pt, one table with different +borders -- breaks that trust and makes the reader question the content. + +Consistency also reduces cognitive load. Once the reader learns "bold dark blue += section heading," they stop spending mental effort on identifying structure +and focus entirely on content. Every inconsistency forces them to re-evaluate: +"Is this a different kind of heading, or did someone just forget to apply the +style?" + +The implementation rule is simple: **use named styles, not direct formatting.** +If you define Heading2 as a style and apply it everywhere, consistency is +automatic. If you manually set font size, bold, and color on each heading +individually, inconsistency is inevitable. + +### Good Example + +```xml + + + + + + + + + + + + + + + + + + + + + + + + + + Market Analysis + +``` + +When using a table style, define it once and reference it for every table: + +```xml + + + + + +``` + +### Bad Example + +```xml + + + + + + + + + + + + Market Analysis + + + + + + + + + + + + + + + Financial Overview + + +``` + +Problems: +- No style references -- everything is direct formatting. +- Second H2 has different size (30 vs 32), color, and spacing. +- If there are 20 headings, each could drift slightly differently. +- Changing the design later means editing every heading individually. + +### Quick Test + +1. **Style audit**: does every paragraph reference a `w:pStyle`? If you find + paragraphs with only direct formatting and no style, that is a consistency + risk. +2. **Search for variance**: search the XML for all `w:sz` values used with + `w:b` (bold). If you find three different sizes for what should be the same + heading level, there is an inconsistency. +3. **Table check**: do all tables in the document reference the same + `w:tblStyle`? If some tables have manual border definitions while others + use a style, the document will look patchy. +4. **Page numbers**: check that header/footer content is defined in the + default section properties and inherited by all sections, not redefined + inconsistently in each section. + +--- + +## 6. Visual Hierarchy & Flow + +### Why It Works + +A well-designed document guides the reader's eye in a predictable path: +title at the top, subtitle below it, section headings as signposts, body text +as the main content, footnotes and captions as supporting details. This flow +mirrors reading priority -- the most important information is the most visually +prominent. + +Each level in the hierarchy must be **distinguishable from its adjacent +levels**. It is not enough for H1 to differ from body text; H1 must also +clearly differ from H2, and H2 from H3. If any two adjacent levels are too +similar, the hierarchy collapses at that point. + +Effective hierarchy uses **multiple simultaneous signals**: + +| Level | Size | Weight | Color | Spacing above | +|----------|-------|---------|---------|---------------| +| Title | 26pt | Bold | #1F3864 | 0 (top) | +| Subtitle | 15pt | Regular | #4472C4 | 4pt | +| H1 | 20pt | Bold | #1F3864 | 24pt | +| H2 | 16pt | Bold | #1F3864 | 18pt | +| H3 | 13pt | Bold | #1F3864 | 12pt | +| Body | 11pt | Regular | #333333 | 0pt | +| Caption | 9pt | Italic | #666666 | 4pt | +| Footnote | 9pt | Regular | #666666 | 0pt | + +Notice how each level differs from its neighbors on at least two dimensions +(size + weight, or size + color, or weight + style). Single-dimension +differences are fragile and can be missed. + +**Section breaks** create rhythm in long documents. A page break before each +major section (H1) gives the reader a mental reset. Within sections, consistent +heading + body patterns create a predictable cadence that makes long documents +less intimidating. + +### Good Example + +```xml + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + +``` + +``` + Visual flow (good): + + +----------------------------------+ + | | + | ANNUAL REPORT 2025 | <- Title: 26pt bold navy centered + | Acme Corporation | <- Subtitle: 15pt regular blue + | | + | | + +----------------------------------+ + + +----------------------------------+ + | | + | 1. Executive Summary | <- H1: 20pt bold navy (page break) + | | + | Body text introducing the | <- Body: 11pt regular gray + | main findings of the year. | + | | + | 1.1 Revenue Highlights | <- H2: 16pt bold navy + | | + | Revenue grew by 23% year | <- Body + | over year, driven by... | + | | + | Figure 1: Revenue Growth | <- Caption: 9pt italic gray + | | + +----------------------------------+ + + Each level is immediately identifiable. The eye flows naturally + from title -> heading -> body -> caption. +``` + +### Bad Example + +```xml + + + + + + + + + + + + + + + + + + + +``` + +Problems: +- H1 at 14pt is too close to body at 11pt (ratio 1.27 -- acceptable in + isolation but with black color matching body, the hierarchy is weak). +- Caption is indistinguishable from body text. +- No page breaks means major sections bleed into each other with no + visual rhythm. +- Everything is black, so color provides zero hierarchy signal. + +### Quick Test + +1. **The squint test**: blur your eyes while looking at a full page. You + should see 3-4 distinct "weight levels" of gray. If the page looks like + one uniform shade, the hierarchy is too flat. +2. **The scan test**: flip through pages quickly. Can you identify section + boundaries in under one second per page? If yes, the visual hierarchy is + working. If pages blur together, you need stronger differentiation at H1. +3. **Adjacent level test**: for each heading level, check that it differs + from the next level on at least 2 of: size, weight, color, style (italic). + Single-dimension differences get lost. +4. **Rhythm test**: in a document over 10 pages, do major sections (H1) start + on new pages? If not, long documents will feel like an undifferentiated + stream.

Always load the original file. +2. The output MUST contain the **same sheets** as the input (same names, same data). +3. Only modify the specific cells the task asks for — everything else must be untouched. +4. **After saving output.xlsx, verify it**: open with `xlsx_reader.py` or `pandas` and confirm the original sheet names and a sample of original data are present. If verification fails, you wrote the wrong file — fix it before delivering. + +Never use openpyxl round-trip on existing files (corrupts VBA, pivots, sparklines). Instead: unpack → use helper scripts → repack. + +**"Fill cells" / "Add formulas to existing cells" = EDIT task.** If the input file already exists and you are told to fill, update, or add formulas to specific cells, you MUST use the XML edit path. Never create a new `Workbook()`. Example — fill B3 with a cross-sheet SUM formula: +```bash +python3 SKILL_DIR/scripts/xlsx_unpack.py input.xlsx /tmp/xlsx_work/ +# Find the target sheet's XML via xl/workbook.xml → xl/_rels/workbook.xml.rels +# Then use the Edit tool to add inside the target element: +# SUM('Sales Data'!D2:D13) +python3 SKILL_DIR/scripts/xlsx_pack.py /tmp/xlsx_work/ output.xlsx +``` + +**Add a column** (formulas, numfmt, styles auto-copied from adjacent column): +```bash +python3 SKILL_DIR/scripts/xlsx_unpack.py input.xlsx /tmp/xlsx_work/ +python3 SKILL_DIR/scripts/xlsx_add_column.py /tmp/xlsx_work/ --col G \ + --sheet "Sheet1" --header "% of Total" \ + --formula '=F{row}/$F$10' --formula-rows 2:9 \ + --total-row 10 --total-formula '=SUM(G2:G9)' --numfmt '0.0%' \ + --border-row 10 --border-style medium +python3 SKILL_DIR/scripts/xlsx_pack.py /tmp/xlsx_work/ output.xlsx +``` +The `--border-row` flag applies a top border to ALL cells in that row (not just the new column). Use it when the task requires accounting-style borders on total rows. + +**Insert a row** (shifts existing rows, updates SUM formulas, fixes circular refs): +```bash +python3 SKILL_DIR/scripts/xlsx_unpack.py input.xlsx /tmp/xlsx_work/ +# IMPORTANT: Find the correct --at row by searching for the label text +# in the worksheet XML, NOT by using the row number from the prompt. +# The prompt may say "row 5 (Office Rent)" but Office Rent might actually +# be at row 4.

Use the actual row number + 1 for `--at`. Do NOT call `xlsx_shift_rows.py` separately — `xlsx_insert_row.py` calls it internally. + +**Apply row-wide borders** (e.g. accounting line on a TOTAL row): +After running helper scripts, apply borders to ALL cells in the target row, not just newly added cells. In `xl/styles.xml`, append a new `` with the desired style, then append a new `` in `` that clones each cell's existing `` but sets the new `borderId`. Apply the new style index to every `` in the row via the `s` attribute: +```xml + + + + + +``` +**Key rule**: When a task says "add a border to row N", iterate over ALL cells A through the last column, not just newly added cells. + +**Manual XML edit** (for anything the helper scripts don't cover): +```bash +python3 SKILL_DIR/scripts/xlsx_unpack.py input.xlsx /tmp/xlsx_work/ +# ... edit XML with the Edit tool ... +python3 SKILL_DIR/scripts/xlsx_pack.py /tmp/xlsx_work/ output.xlsx +``` + +## FIX — Repair broken formulas (read `references/fix.md` first) + +This is an EDIT task.

If the script reports `xl/vbaProject.bin` or `xl/pivotTables/`, follow the constraints in Section 7. + +### Step 2 — Reconnaissance + +Map the structure before touching anything. + +**Identify sheet names and their XML files:** + +``` +xl/workbook.xml → +xl/_rels/workbook.xml.rels → +``` + +The sheet named "Revenue" lives in `xl/worksheets/sheet1.xml`. Always resolve this mapping before editing a worksheet. + +**Understand the shared strings table:** + +```bash +# Count existing entries in xl/sharedStrings.xml +grep -c "" /tmp/xlsx_work/xl/sharedStrings.xml +``` + +Every text cell uses a zero-based index into this table. Know the current count before appending. + +**Understand the styles table:** + +```bash +# Count existing cellXfs entries +grep -c "` — merged cell ranges; row/column insertion shifts these +- `` — condition ranges; row/column insertion shifts these +- `` — validation ranges; row/column insertion shifts these +- `` — table definitions; row insertion inside a table needs `` updates +- `` — sparklines; preserve without modification + +### Step 3 — Map Intent to Minimal XML Changes + +Before writing a single character, produce a written list of exactly which XML nodes change. This prevents scope creep. + +| User intent | Files to change | Nodes to change | +|-------------|----------------|-----------------| +| Change a cell's numeric value | `xl/worksheets/sheetN.xml` | `` inside target `` | +| Change a cell's text | `xl/sharedStrings.xml` (append) + `xl/worksheets/sheetN.xml` | New ``, update cell `` index | +| Change a cell's formula | `xl/worksheets/sheetN.xml` | `` text inside target `` | +| Add a new data row at the bottom | `xl/worksheets/sheetN.xml` + possibly `xl/sharedStrings.xml` | Append `` element | +| Apply a new style to cells | `xl/styles.xml` + `xl/worksheets/sheetN.xml` | Append `` in ``, update `s` attribute on `` | +| Rename a sheet | `xl/workbook.xml` | `name` attribute on `` element | +| Rename a sheet (with cross-sheet formulas) | `xl/workbook.xml` + all `xl/worksheets/*.xml` | `name` attribute + `` text referencing old name | + +### Step 4 — Execute Changes + +Use the Edit tool. Edit the minimum. Never rewrite whole files. + +See Section 4 for precise XML patterns for each operation type. + +### Step 5 — Cascade Check + +After any change that shifts row or column positions, audit all affected XML regions. See Section 5. + +### Step 6 — Pack and Validate + +```bash +python3 SKILL_DIR/scripts/xlsx_pack.py /tmp/xlsx_work/ output.xlsx +python3 SKILL_DIR/scripts/formula_check.py output.xlsx +``` + +The pack script validates XML well-formedness before creating the ZIP. Fix any reported parse errors before packing. After packing, run `formula_check.py` to confirm no formula errors were introduced. + +--- + +## 4. Precise XML Patterns for Common Edits + +### 4.1 Changing a Numeric Cell Value + +Find the `` element in the worksheet XML and replace the `` text. + +**Before:** +```xml + + 1000 + +``` + +**After (new value 1500):** +```xml + + 1500 + +``` + +Rules: +- Do not add or remove the `s` attribute (style) unless explicitly changing the style. +- Do not add a `t` attribute — numbers omit `t` or use `t="n"`. +- Do not change the `r` attribute (cell reference). + +--- + +### 4.2 Changing a Text Cell Value + +Text cells reference the shared strings table by index (`t="s"`). You cannot edit the string in-place without affecting every other cell that uses the same index. The safe approach is to append a new entry. + +**Before — shared strings file (`xl/sharedStrings.xml`):** +```xml + + Revenue + Cost + Margin + Old Label + +``` + +**After — append new string, increment counts:** +```xml + + Revenue + Cost + Margin + Old Label + New Label + +``` + +New string is at index 4 (zero-based). + +**Before — cell in worksheet XML:** +```xml + + 3 + +``` + +**After — point to new index:** +```xml + + 4 + +``` + +Rules: +- Never modify or delete existing `` entries. Only append. +- Both `count` and `uniqueCount` must be incremented together. +- If the new string contains `&`, `<`, or `>`, escape them: `&`, `<`, `>`. +- If the string has leading or trailing spaces, add `xml:space="preserve"` to ``: + ```xml + indented text + ``` + +--- + +### 4.3 Changing a Formula + +Formulas are stored in `` elements **without a leading `=`** (unlike what you type in Excel's UI). + +**Before:** +```xml + + SUM(C2:C9) + 4800 + +``` + +**After (extended range):** +```xml + + SUM(C2:C11) + + +``` + +Rules: +- Clear `` to an empty string when changing the formula. The cached value is now stale. +- Do not add `t="s"` or any type attribute to formula cells. The `t` attribute is absent or uses a result-type value, not a formula marker. +- Cross-sheet references use `SheetName!CellRef`. If the sheet name contains spaces, wrap in single quotes: `'Q1 Data'!B5`. +- The `` text must not include the leading `=`. + +**Before (converting a hardcoded value to a live formula):** +```xml + + 95000 + +``` + +**After:** +```xml + + SUM(D2:D14) + + +``` + +--- + +### 4.4 Adding a New Data Row + +Append after the last `` element inside ``. Row numbers in OOXML are 1-based and must be sequential. + +**Before (last row is row 10):** +```xml + + 3 + 2023 + 88000 + C10*1.1 + + +``` + +**After (new row 11 appended):** +```xml + + 3 + 2023 + 88000 + C10*1.1 + + + 4 + 2024 + 96000 + C11*1.1 + + +``` + +Rules: +- Every `` inside the row must have `r` set to the correct cell address (e.g., `A11`). +- Text cells need `t="s"` and a sharedStrings index in ``. Numeric cells omit `t`. +- Formula cells use `` and an empty ``. +- Copy the `s` attribute from the row above if you want matching styles. Do not invent a style index that does not exist in `styles.xml`. +- If the sheet contains a `` element (e.g., ``), update it to include the new row: ``. +- If the sheet contains a `` referencing a table, update the table's `ref` attribute in the corresponding `xl/tables/tableN.xml` file. + +--- + +### 4.5 Adding a New Column + +Append new `` elements to each existing `` and, if present, update the `` section. + +**Before (rows have columns A–C):** +```xml + + + + + + 0 + 1 + 2 + + + 100 + 200 + 300 + + +``` + +**After (adding column D):** +```xml + + + + + + + 0 + 1 + 2 + 5 + + + 100 + 200 + 300 + A2+B2+C2 + + +``` + +Rules: +- Adding a column at the end (after the last existing column) is safe — no existing formula references shift. +- Inserting a column in the middle shifts all columns to the right, which requires the same cascade updates as row insertion (see Section 5). +- Update the `` element if present. + +--- + +### 4.6 Modifying or Adding Styles + +Styles use a multi-level indirect reference chain. Read `ooxml-cheatsheet.md` for the full chain. The key rule: **only append new entries, never modify existing ones**. + +**Scenario:** Add a blue-font style (for hardcoded input cells) that doesn't yet exist. + +**Step 1 — Check if a matching font already exists in `xl/styles.xml`:** +```xml + + + + + +``` + +If found, note its index (zero-based position in the `` list). If not found, append. + +**Step 2 — Append the new font if needed:** + +Before: +```xml + + ... + ... + ... + +``` + +After: +```xml + + ... + ... + ... + + + + + + + +``` + +**Step 3 — Append a new `` in ``:** + +Before: +```xml + + + + + + + +``` + +After: +```xml + + + + + + + + +``` + +**Step 4 — Apply to target cells:** + +Before: +```xml + + 0.08 + +``` + +After: +```xml + + 0.08 + +``` + +Rules: +- Never delete or reorder existing entries in ``, ``, ``, ``. +- Always update the `count` attribute when appending. +- The new `cellXfs` index = the old `count` value before appending (zero-based: if count was 5, new index is 5). +- Custom `numFmt` IDs must be 164 or above. IDs 0–163 are built-in and must not be re-declared. +- If the desired style already exists elsewhere in the file (on a similar cell), reuse its `s` index rather than creating a duplicate. + +--- + +### 4.7 Renaming a Sheet + +**Only `xl/workbook.xml` needs to change** — unless cross-sheet formulas reference the old name. + +**Before (`xl/workbook.xml`):** +```xml + +``` + +**After:** +```xml + +``` + +**If any formula in any worksheet references the old name, update those too:** + +Before (`xl/worksheets/sheet2.xml`): +```xml +Sheet1!C10 +``` + +After: +```xml +Revenue!C10 +``` + +If the new name contains spaces: +```xml +'Q1 Revenue'!C10 +``` + +Scan all worksheet XML files for the old name: +```bash +grep -r "Sheet1!" /tmp/xlsx_work/xl/worksheets/ +``` + +Rules: +- The `.rels` file and `[Content_Types].xml` do NOT need to change — they reference the XML file path, not the sheet name. +- `sheetId` must not change; it is a stable internal identifier. +- Sheet names are case-sensitive in formula references. + +--- + +## 5. High-Risk Operations — Cascade Effects + +### 5.1 Inserting a Row in the Middle + +Inserting a row at position N shifts all rows from N downward. Every reference to those rows in every XML file must be updated. + +**Files to check and update:** + +| XML region | What to update | Example shift | +|------------|---------------|---------------| +| Worksheet `` attributes | Increment row number for all rows >= N | `r="7"` → `r="8"` | +| All `` within those rows | Increment row number in cell address | `r="A7"` → `r="A8"` | +| All `` formula text in any sheet | Shift absolute row references >= N | `B7` → `B8` | +| `` | Shift start and end rows | `A7:C7` → `A8:C8` | +| `` | Shift range | `A5:D20` → `A5:D21` | +| `` | Shift range | `B6:B50` → `B7:B51` | +| `xl/charts/chartN.xml` data source ranges | Shift series ranges | `Sheet1!$B$5:$B$20` → `Sheet1!$B$6:$B$21` | +| `xl/pivotTables/*.xml` source ranges | Shift source data range | Handle with extreme care — see Section 7 | +| `` | Expand to include new extent | `A1:D20` → `A1:D21` | +| `xl/tables/tableN.xml` `ref` attribute | Expand table boundary | `A1:D20` → `A1:D21` | + +**Do not attempt row insertion manually in large or formula-heavy files.** Use the dedicated shift script instead: + +```bash +# Insert 1 row at row 5: all rows 5 and below shift down by 1 +python3 SKILL_DIR/scripts/xlsx_shift_rows.py /tmp/xlsx_work/ insert 5 1 + +# Delete 1 row at row 8: all rows 9 and above shift up by 1 +python3 SKILL_DIR/scripts/xlsx_shift_rows.py /tmp/xlsx_work/ delete 8 1 +``` + +The script updates in one pass: `` attributes, `` cell addresses, all `` formula text across every worksheet, `` ranges, ``, ``, ``, table `ref` attributes in `xl/tables/`, chart series ranges in `xl/charts/`, and pivot cache source ranges in `xl/pivotCaches/`. + +**After running the shift script, always repack and validate:** +```bash +python3 SKILL_DIR/scripts/xlsx_pack.py /tmp/xlsx_work/ output.xlsx +python3 SKILL_DIR/scripts/formula_check.py output.xlsx +``` + +**What the script does NOT update (review manually):** +- Named ranges in `xl/workbook.xml` `` — check and update if they reference shifted rows. +- Structured table references (`Table[@Column]`) inside formulas. +- External workbook links in `xl/externalLinks/`. + +### 5.2 Inserting a Column in the Middle + +Same cascade logic as row insertion, but for columns. Column references in formulas (`B`, `$C`, etc.) and in merged cell ranges, conditional formatting ranges, and chart data sources all need updating. + +Column letter shifting is harder to automate safely. Prefer **appending columns at the end** whenever possible. + +### 5.3 Deleting a Row or Column + +Deletion is more dangerous than insertion because any formula that referenced a deleted row or column will become `#REF!`. Before deleting: + +1. Search all `` elements for references to the deleted range. +2. If any formula references a cell in the deleted row/column, do not delete — instead, either clear the row's data or consult the user. +3. After deletion, shift all references to rows/columns beyond the deletion point downward/leftward. + +--- + +## 6. Template Filling — Identifying and Populating Input Cells + +Templates designate certain cells as input zones. Common patterns to recognize them: + +### 6.1 How Templates Signal Input Zones + +| Signal | XML manifestation | What to look for | +|--------|-------------------|-----------------| +| Blue font color | `s` attribute pointing to a `cellXfs` entry with `fontId` → `` | Check `styles.xml` to decode `s` values | +| Yellow fill (highlight) | `s` → `fillId` → `` | | +| Empty `` element | `` or cell entirely absent from `` | The cell has no value yet | +| Comment/annotation near cell | `xl/comments1.xml` with `ref="B5"` | Comments often label input fields | +| Named ranges | `xl/workbook.xml` `` elements | Template may define `InputRevenue` etc. | + +### 6.2 Filling a Template Cell + +Do not change `s` attributes. Do not change `t` attributes unless you must change from empty to typed. Only change `` or add ``. + +**Before (empty input cell with style preserved):** +```xml + + + +``` + +**After (filled with a number, style unchanged):** +```xml + + 125000 + +``` + +**After (filled with text — requires shared string entry first):** +```xml + + + 7 + +``` + +**After (filled with a formula, preserving style):** +```xml + + Assumptions!D12 + + +``` + +### 6.3 Locating Input Zones Without Opening the File in Excel + +After unpacking, decode the style index on suspected input cells to determine if they have the template's input color: + +1. Note the `s` value on the cell (e.g., `s="4"`). +2. In `xl/styles.xml`, find `` and look at the 5th entry (index 4). +3. Note its `fontId` (e.g., `fontId="2"`). +4. In ``, look at the 3rd entry (index 2) and check for `` (blue) or other input marker. + +If the template uses named ranges as input fields, read them from `xl/workbook.xml`: +```xml + + Assumptions!$B$5 + Assumptions!$B$6 + +``` + +Fill the target cells (`Assumptions!B5`, `Assumptions!B6`) directly. + +### 6.4 Template Filling Rules + +- Fill only cells the template designated as inputs. Do not fill cells that are formula-driven. +- Do not apply new styles when filling. The template's formatting is the deliverable. +- Do not add or remove rows inside the template's data area unless the template explicitly has an "append here" zone. +- After filling, verify that no formula errors were introduced: some templates have input-validation formulas that produce `#VALUE!` if the wrong data type is entered. + +--- + +## 7. Files You Must Never Modify + +### 7.1 Absolute no-touch list + +| File / location | Why | +|-----------------|-----| +| `xl/vbaProject.bin` | Binary VBA bytecode. Any byte modification corrupts the macro project. Editing even one bit makes the macros fail to load. | +| `xl/pivotCaches/pivotCacheDefinition*.xml` | The cache definition ties the pivot table to its source data. Editing it without also updating the corresponding `pivotTable*.xml` will corrupt the pivot. | +| `xl/pivotTables/*.xml` | Pivot table XML is tightly coupled with the cache definition and with internal state Excel rebuilds on load. Do not edit. If you shifted rows and the pivot's source range now points to wrong data, update only the `` range in the cache definition, and only the `ref` attribute in the pivot table — no other changes. | +| `xl/slicers/*.xml` | Slicers are connected to specific cache IDs and pivot fields. Breaking these connections silently corrupts the file. | +| `xl/connections.xml` | External data connections. Editing breaks live data refresh. | +| `xl/externalLinks/` | External workbook links. The binary `.bin` files in here must not be modified. | + +### 7.2 Conditionally safe files (update only specific attributes) + +| File | What you may update | What to leave alone | +|------|--------------------|--------------------| +| `xl/charts/chartN.xml` | Data series range references (``) after a row/column shift | Chart type, formatting, layout | +| `xl/tables/tableN.xml` | `ref` attribute on `` after adding rows | Column definitions, style info | +| `xl/pivotCaches/pivotCacheDefinition*.xml` | `ref` attribute on `` after shifting source data | All other content | + +--- + +## 8. Validation After Every Edit + +Never skip validation.

If the business expectation is that the result should display as blank rather than zero, use `IFERROR(...,"")` instead. + +--- + +### #VALUE! — Wrong Data Type + +**What it means:** The formula attempts an arithmetic or logical operation on a value of the wrong type (e.g., adding a text string to a number). + +**Common causes in generated files:** +- A cell intended to hold a number was written as a string type (`t="s"` or `t="inlineStr"`) instead of a numeric type +- A formula references a cell containing text (e.g., a unit label like "thousands") and treats it as a number + +**XML signature:** +```xml + + E3+D3 + #VALUE! + +``` + +**Fix — check source cells for incorrect type:** + +If `D3` was incorrectly written as a string: +```xml + +1000 + + +1000 +``` + +Alternatively, wrap the formula with `VALUE()` conversion: +```xml + + VALUE(E3)+VALUE(D3) + + +``` + +**Auto-fixable?** Partially. If the source cell type is visibly wrong (a number stored as string), fix the type. If the cause is ambiguous (the cell is supposed to contain text), flag for human review. + +--- + +### #NAME? — Unrecognized Name + +**What it means:** The formula contains an identifier that Excel does not recognize — either a misspelled function name, an undefined named range, or a function that is not available in the target Excel version. + +**Common causes in generated files:** +- LLM writes a function name with a typo: `SUMIF` written as `SUMIFS` when only 3 arguments are provided, or `XLOOKUP` used in a context targeting Excel 2010 +- Named range referenced in formula does not exist in `xl/workbook.xml` + +**XML signature:** +```xml + + SUMSQ(A2:A10) + #NAME? + +``` + +**Fix — verify function name and named ranges:** + +Check named ranges in `xl/workbook.xml`: +```xml + + Sheet1!$B$2:$B$13 + +``` + +If the formula references `RevenuRange` (typo), correct it to `RevenueRange`: +```xml + + SUM(RevenueRange) + + +``` + +**Auto-fixable?** Only if the correct name is unambiguous (e.g., a single close match exists). Otherwise flag for human review — function name fixes require understanding the intended calculation. + +--- + +### #N/A — Value Not Available + +**What it means:** A lookup function (VLOOKUP, HLOOKUP, MATCH, INDEX/MATCH, XLOOKUP) searched for a value that does not exist in the lookup table. + +**Common causes in generated files:** +- Lookup key exists in the formula but the lookup table is empty or not yet populated +- Key format mismatch (text "2024" vs numeric 2024) + +**XML signature:** +```xml + + VLOOKUP(F5,Assumptions!$A$2:$B$20,2,0) + #N/A + +``` + +**Fix — wrap with IFERROR for missing-match tolerance:** +```xml + + IFERROR(VLOOKUP(F5,Assumptions!$A$2:$B$20,2,0),0) + + +``` + +**Auto-fixable?** Adding `IFERROR` is safe if a zero default is acceptable. If the lookup failure indicates a data integrity problem (the key should always be present), do not auto-fix — flag for human review. + +--- + +### #NULL! — Empty Intersection + +**What it means:** The space operator (which computes the intersection of two ranges) was applied to two ranges that do not intersect. + +**Common causes in generated files:** +- Accidental space between two range references: `=SUM(A1:A5 C1:C5)` instead of `=SUM(A1:A5,C1:C5)` +- Rarely seen in typical financial models; usually indicates a formula generation error + +**XML signature:** +```xml + + SUM(A1:A5 C1:C5) + #NULL! + +``` + +**Fix — replace space with comma (union) or colon (range):** +```xml + + + SUM(A1:A5,C1:C5) + + +``` + +**Auto-fixable?** Yes. The space operator is almost never intentional in generated formulas. Replacing with a comma is safe. + +--- + +### #NUM! — Numeric Error + +**What it means:** A formula produced a number that Excel cannot represent (overflow, underflow) or a mathematical operation that has no real-number result (square root of negative, LOG of zero or negative). + +**Common causes in generated files:** +- IRR or NPV formula where the cash flow series has no convergent solution +- `SQRT()` applied to a cell that can be negative +- Very large exponentiation + +**XML signature:** +```xml + + IRR(B5:B15) + #NUM! + +``` + +**Fix — add a conditional guard:** +```xml + + IFERROR(IRR(B5:B15),"") + + +``` + +For SQRT: +```xml + + IF(A5>=0,SQRT(A5),"") + + +``` + +**Auto-fixable?** Partially. Wrapping with `IFERROR` suppresses the error display but does not fix the underlying calculation issue.

It will find any broken cross-sheet references if sheet names were misspelled. Tier 2 will populate `` and reveal runtime errors like `#DIV/0!`. + +If Tier 2 reveals errors, fix them in the source XML (not the recalculated copy), repack, and re-run both tiers. + +### Scenario 2: Validate after editing an existing file + +When `edit.md` workflow modifies an existing xlsx, validate only the affected sheets if the edit was surgical. If the edit touched shared formulas or cross-sheet references, validate all sheets. + +```bash +# Targeted static check — look at specific sheet +# (formula_check.py checks all sheets; examine only the relevant section of output) +python3 SKILL_DIR/scripts/formula_check.py /path/to/edited.xlsx --json \ + | python3 -c " +import json, sys +r = json.load(sys.stdin) +for e in r['errors']: + if e.get('sheet') in ['Summary', 'Q1']: + print(e) +" +``` + +Always run Tier 2 after edits that modify formulas, even if Tier 1 passes. Edits to data ranges can cause previously-valid formulas to produce runtime errors. + +### Scenario 3: User provides a file with suspected formula errors + +When a user submits a file and reports wrong values or visible errors: + +```bash +# Step 1: Static scan — find all error cells +python3 SKILL_DIR/scripts/formula_check.py /path/to/user_file.xlsx --json > /tmp/validation_results.json + +# Step 2: Unpack for manual inspection +python3 SKILL_DIR/scripts/xlsx_unpack.py /path/to/user_file.xlsx /tmp/xlsx_inspect/ + +# Step 3: Dynamic recalculation +python3 SKILL_DIR/scripts/libreoffice_recalc.py /path/to/user_file.xlsx /tmp/user_file_recalc.xlsx + +# Step 4: Re-validate recalculated file +python3 SKILL_DIR/scripts/formula_check.py /tmp/user_file_recalc.xlsx --json > /tmp/validation_after_recalc.json + +# Step 5: Compare before and after +python3 - <<'EOF' +import json +before = json.load(open("/tmp/validation_results.json")) +after = json.load(open("/tmp/validation_after_recalc.json")) +print(f"Before recalc: {before['error_count']} errors") +print(f"After recalc: {after['error_count']} errors") +EOF +``` + +If errors appear only after recalculation (not in the original static scan), the formulas were syntactically correct but produce wrong results at runtime. These are runtime errors that require formula-level fixes, not XML-structure fixes. + +If errors appear in both scans, they were already cached in `` before recalculation — the file was previously opened by Excel/LibreOffice and the errors persisted. + +--- + +## Critical Pitfalls + +**Pitfall 1: openpyxl `data_only=True` destroys formulas.** +Opening a workbook with `data_only=True` reads cached values instead of formulas. If you then save the workbook, all `` elements are permanently removed and replaced with their last-cached values. Never use this mode for validation workflows. + +**Pitfall 2: Empty `` is not the same as a passing formula.** +A freshly generated file has empty `` elements for all formula cells. formula_check.py will not report these as errors — they are not yet errors. They become errors only after recalculation if the calculated value is an error type. This is why Tier 2 is mandatory. + +**Pitfall 3: Shared formula errors affect the entire range.** +If a shared formula's primary cell has a broken reference, every cell in the shared range (`ref="D2:D100"`) inherits that broken reference. The count of logical errors can be much larger than the count of distinct error entries in formula_check.py output. When fixing a broken shared formula, fix the primary cell's `` element; the consumers (``) automatically inherit the corrected formula. + +**Pitfall 4: Sheet names are case-sensitive.** +`=q1!B5` and `=Q1!B5` are different references. Excel internally treats them the same, but formula_check.py's string comparison is case-sensitive. If a formula uses a lowercase sheet name that matches an uppercase sheet in the workbook, it will be flagged as a broken reference. The fix is to match the exact case in `workbook.xml`. + +**Pitfall 5: `--convert-to xlsx` does not guarantee formula preservation.** +LibreOffice's conversion can occasionally alter certain formula types (array formulas, dynamic array functions like `SORT`, `UNIQUE`). After Tier 2, if the recalculated file shows formula changes unrelated to error fixing, do not deliver the recalculated file directly — use the original file with targeted XML fixes instead. diff --git a/skills/minimax-xlsx/scripts/formula_check.py b/skills/minimax-xlsx/scripts/formula_check.py new file mode 100644 index 0000000..ee3ce15 --- /dev/null +++ b/skills/minimax-xlsx/scripts/formula_check.py @@ -0,0 +1,422 @@ +#!/usr/bin/env python3 +# SPDX-License-Identifier: MIT +""" +formula_check.py — Static formula validator for xlsx files. + +Usage: + python3 formula_check.py + python3 formula_check.py --json # machine-readable output + python3 formula_check.py --report # standardized validation report (JSON) + python3 formula_check.py --report -o out # report to file + python3 formula_check.py --sheet Sales # limit to one sheet + python3 formula_check.py --summary # error counts only, no details + +What it checks: +1.

It also covers running tests in CI pipelines. + +## When to Use This Skill + +- Writing unit tests for a custom model's business logic. +- Creating an HTTP test to verify a controller endpoint. +- Debugging test failures in a CI pipeline. +- Setting up automated test execution with `--test-enable`. + +## How It Works + +1. **Activate**: Mention `@odoo-automated-tests` and describe the feature to test. +2. **Generate**: Get complete test class code with setup, teardown, and assertions. +3. **Run**: Get the exact `odoo` CLI command to execute your tests. + +## Examples + +### Example 1: TransactionCase Unit Test (Odoo 15+ pattern) + +```python +# tests/test_hospital_patient.py +from odoo.tests.common import TransactionCase +from odoo.tests import tagged +from odoo.exceptions import ValidationError + +@tagged('post_install', '-at_install') +class TestHospitalPatient(TransactionCase): + + @classmethod + def setUpClass(cls): + # Use setUpClass for performance — runs once per class, not per test + super().setUpClass() + cls.Patient = cls.env['hospital.patient'] + cls.doctor = cls.env['res.users'].browse(cls.env.uid) + + def test_create_patient(self): + patient = self.Patient.create({ + 'name': 'John Doe', + 'doctor_id': self.doctor.id, + }) + self.assertEqual(patient.state, 'draft') + self.assertEqual(patient.name, 'John Doe') + + def test_confirm_patient(self): + patient = self.Patient.create({'name': 'Jane Smith'}) + patient.action_confirm() + self.assertEqual(patient.state, 'confirmed') + + def test_empty_name_raises_error(self): + with self.assertRaises(ValidationError): + self.Patient.create({'name': ''}) + + def test_access_denied_for_other_user(self): + # Test security rules by running as a different user + other_user = self.env.ref('base.user_demo') + with self.assertRaises(Exception): + self.Patient.with_user(other_user).create({'name': 'Test'}) +``` + +> **`setUpClass` vs `setUp`:** Use `setUpClass` (Odoo 15+) for shared test data. It runs once per class and is significantly faster than `setUp` which re-initializes for every single test method. + +### Example 2: Run Tests via CLI + +```bash +# Run all tests for a specific module +./odoo-bin --test-enable --stop-after-init -d my_database -u hospital_management + +# Run only tests tagged with a specific tag +./odoo-bin --test-enable --stop-after-init -d my_database \ + --test-tags hospital_management + +# Run a specific test class +./odoo-bin --test-enable --stop-after-init -d my_database \ + --test-tags /hospital_management:TestHospitalPatient +``` + +### Example 3: HttpCase for Controller Testing + +```python +from odoo.tests.common import HttpCase +from odoo.tests import tagged + +@tagged('post_install', '-at_install') +class TestPatientController(HttpCase): + + def test_patient_page_authenticated(self): + # Authenticate as a user, not with hardcoded password + self.authenticate(self.env.user.login, self.env.user.login) + resp = self.url_open('/hospital/patients') + self.assertEqual(resp.status_code, 200) + + def test_patient_page_redirects_unauthenticated(self): + # No authenticate() call = public/anonymous user + resp = self.url_open('/hospital/patients', allow_redirects=False) + self.assertIn(resp.status_code, [301, 302, 403]) +``` + +## Best Practices + +- ✅ **Do:** Use `setUpClass()` with `cls.env` instead of `setUp()` — it is dramatically faster for large test suites. +- ✅ **Do:** Use `@tagged('post_install', '-at_install')` to run tests after all modules are installed. +- ✅ **Do:** Test both the happy path and error conditions (`ValidationError`, `AccessError`, `UserError`). +- ✅ **Do:** Use `self.with_user(user)` to test access control without calling `sudo()`. +- ❌ **Don't:** Use a production database for tests — always use a dedicated test database. +- ❌ **Don't:** Rely on test execution order — each `TransactionCase` test is rolled back in isolation. +- ❌ **Don't:** Hardcode passwords in `HttpCase.authenticate()` — use `self.env.user.login` or a fixture user. + +## Limitations + +- **JavaScript tour tests** require a running browser (via `phantomjs` or `Chrome headless`) and a live Odoo server — not covered in depth here. +- `HttpCase` tests are significantly slower than `TransactionCase` — use them only for controller/route verification. +- Does not cover **mocking external services** (e.g., mocking an SMTP server or payment gateway in tests). +- Test isolation is at the **transaction level**, not database level — tests that commit data (e.g., via `cr.commit()`) can leak state between tests. diff --git a/skills/pentesting/SKILL.md b/skills/pentesting/SKILL.md new file mode 100644 index 0000000..6cf419e --- /dev/null +++ b/skills/pentesting/SKILL.md @@ -0,0 +1,383 @@ +--- +name: pentesting +description: | + Penetration testing skill combining SQL injection, command injection, SSRF, HTML injection, + SSH, and WordPress penetration testing.
