Apple HIG for Agents
V2 is updated with iOS 27 support and Apple's latest design philosophy, giving agents a sharper, more current foundation for Apple platform design. HIG turns the Apple Human Interface Guidelines into a skill that agents can use to design better for Apple's platforms, and do better design work in general. The compact, agent-ready reference files preserve the details designers and builders actually need: exact measurements, platform distinctions, API names, component rules, accessibility guidance, and design principles. Instead of relying on fuzzy memory or loading the full HIG into context, agents follow a routing protocol that pulls only the relevant guidance for the task, then answers with precise, citable Apple design direction across iOS, iPadOS, macOS, tvOS, visionOS, and watchOS.
The Apple HIG has the right authority, but it is too large and prose-heavy to drop into an agent's context every time a design question comes up. This skill distills it into 156 compact reference files.
The goal is not to make an agent "inspired by Apple." It is to give the agent precise, current guidance about real platform behavior, component expectations, and design constraints. The June 2026 refresh updated the skill for iOS 27, Liquid Glass, and current Apple platform guidance.
The shape of the skill matters as much as the source material. Instead of one giant reference blob, the content is split so an agent can pull the relevant platform, component, or interaction guidance at the moment it needs it.
