If you're building Apple platform apps and need quick access to the HIG without context switching, this drops the entire Human Interface Guidelines into your coding agent's context. It covers the three core principles (clarity, consistency, deference) plus detailed guidance on components, patterns, and platform conventions. Honestly most useful when you're making design decisions mid-implementation and want to check Apple's stance without opening another browser tab. The 945 stars suggest the parent axiom repo has other useful reference skills too, though this one focuses specifically on interface guidelines. Good for anyone who finds themselves Googling HIG recommendations multiple times a day.
