Apple Human Interface Guidelines for content display components. Use this skill when the user asks about "charts component", "collection view", "image view", "web view", "color well", "image well", "activity view", "lockup", "data visualization", "content display", displaying images, rendering web content, color pickers, or presenting collections of items in Apple apps. Also use when the user says "how should I display charts", "what's the best way to show images", "should I use a web view", "how do I build a grid of items", "what component shows media", or "how do I present a share sheet". Cross-references: hig-foundations for color/typography/accessibility, hig-patterns for data visualization patterns, hig-components-layout for structural containers, hig-platforms for platform-specific component behavior.
SwiftUI NavigationStack, NavigationSplitView, and navigation transition patterns for iOS 16-18+. Covers @Observable coordinators, zoom transitions, hero animations, sheet vs push decisions, multi-step flows, anti-patterns, performance, accessibility, deep linking, and state restoration.

This skill should be used when a team wants to create or refine the design guidelines document — for example "create the design steering doc", "document our design system", "write the design principles", "document our component patterns", "set up the design guidelines", or "update the design doc". Generates docs/steering/DESIGN.md as a living document capturing design principles, the design system, tokens, component patterns, and accessibility standards. Generated once and refined — not regenerated from scratch.

Readability and rendering audit for figures and tables in academic manuscripts. Computes effective font/marker sizes at display scale from generation scripts, checks label collisions, color/hatch accessibility, axis-range efficiency, table formatting, and cross-figure consistency. Triggers on: "check figure quality", "audit plots", "readability check", "figure rendering", "are my figures readable", "table formatting check". Companion to figure-rhetoric (visual argument) and manuscript-typography (typesetting).
