Use when shipping a macOS app outside the App Store — Developer ID signing with hardened runtime, notarization with notarytool, stapling, building a clean drag-to-Applications DMG, and verifying the result launches on a stranger's Mac.
Use when reading, writing, or watching the macOS clipboard — NSPasteboard types and multiple representations, the changeCount polling pattern, the transient/concealed pasteboard conventions clipboard tools must respect, and the Sequoia paste-privacy alerts.
Use when adding or reviewing keyboard shortcuts in a macOS app — in-app vs global, RegisterEventHotKey vs the KeyboardShortcuts package vs NSEvent monitors, user-configurable recording, conflict handling, and which defaults won't collide with the system.
Use when adding, reviewing, or debugging Launch at Login in a macOS app — SMAppService registration, the requiresApproval state, a Settings toggle that reflects reality, and migration off deprecated login-item APIs.
Use when adding or reviewing macOS user notifications — UNUserNotificationCenter permission flow, categories and action buttons, click routing through the delegate, foreground presentation, and rules that keep notifications from becoming spam.
Use when a macOS app needs a TCC permission or touches private data — the map of which API, Info.plist key, and entitlement each permission needs, pre-prompt explanation patterns, denied-state recovery with System Settings deep links, and honest privacy copy.

If everything shouts, nothing stands out.
Contrast tells users where to look first.
Accent colors only work when they're rare.
Tiny shifts create different feelings.
#1a1a1a or #121212 instead of #000#FAFAF7 or #F5F5F0 instead of #FFFUsers shouldn't have to relearn your colors.
Whitespace makes color intentional.
When reviewing a design, structure the response as:
Pairs well with kika-design-system — these are the general review lens; that skill is one opinionated system built on them.
