Axiom Design

A comprehensive reference for Apple platform design decisions covering HIG compliance, Liquid Glass materials, SF Symbols, typography, and app architecture patterns. You'll reach for this when choosing semantic colors, implementing Liquid Glass effects (not just blur), picking SF Symbols rendering modes, or structuring authentication flows and app entry points. The decision trees are genuinely helpful for navigating when to use Regular versus Clear glass variants or which text style fits your hierarchy. It's opinionated about doing design decisions before implementation, which is the right call. The conflict resolution section that explicitly maps design choices to accessibility and SwiftUI skills saves you from guessing which reference to consult first.

Design & HIG

You MUST use this skill for ANY visual design, HIG compliance, Liquid Glass, SF Symbols, typography, or app composition work.

Auditors are skills here. Where this router says "Launch some-auditor agent", invoke the matching Codex skill instead — same procedure, no Claude Code agent required.

Available: axiom-audit-liquid-glass.

The ones that shell out — builds, tests, simulators, crash symbolication — need shell access to run.
