# iOS agent instructions

## Follow the Apple Human Interface Guidelines

Before you add or change iOS UI, fetch and read the Apple Human Interface
Guidelines page for the component or pattern you are touching
(https://developer.apple.com/design/human-interface-guidelines), and follow it
by default. This covers layout, navigation, gestures, keyboard behavior,
haptics, color, typography, and system component usage. When cmux deviates
from the HIG deliberately, say so in the PR description and name the HIG page
you checked. If you cannot fetch the page (offline sandbox), state that in the
PR instead of guessing.
