Manage Claude Code context windows, resume work across sessions, and maintain continuity when your Mac restarts or sessions expire. Use this skill when starting a new session on an existing project, when context feels stale, or when Claude Code starts making mistakes it shouldn't. Prevents the "Claude forgot everything" problem.
Safe patterns for Claude Code interacting with Xcode projects. Covers .pbxproj protection (critical), XcodeBuildMCP build/test patterns, the RenderPreview visual feedback loop, and when to use terminal Claude Code vs Xcode's built-in Claude Agent. Use this skill throughout the entire build process. The .pbxproj rule alone prevents hours of wasted debugging.
Git conventions for parallel Claude Code workstreams in Conductor. Covers branching strategy, merge order, conflict prevention, shared file protection, and the checkpoint pattern. Use this skill throughout the build phase, especially when running multiple Conductor workspaces. Prevents the merge conflicts and corrupted state that kill momentum.
Test every screen in BOTH light and dark mode every iteration. The most common iOS legibility bugs only show in one mode, including a specific class of vibrancy-on-pastel-tint failures that produce illegible labels on glass buttons. Use this skill alongside polish-and-refinement during the polish phase, and as a checklist any time you change colors, tints, or glass surfaces.
How strokes, anti-aliasing, and pixel boundaries actually behave in SwiftUI Canvas and Shape rendering. Covers stroke centering, inset-vs-outset, anti-alias-induced flicker on animating strokes, and 1pt vs 0.5pt strokes on retina displays. Use this skill for any app that draws on a grid or canvas — pattern designers, illustration tools, charting, finger-paint, whiteboards, image editors, gauge / dial UIs.
How to actually prove a UI change works before claiming it does. Covers AX-coordinate snapshots over screenshots, tap-by-label over coordinates, simulator state resets between iterations, and the build → screenshot → AX → math-check loop. Use this skill alongside testing-strategy whenever you're verifying a UI fix on simulator. Required reading before claiming any visual fix is "done."
How to bridge UIKit into a SwiftUI app correctly when SwiftUI's API is genuinely insufficient. Covers UIViewRepresentable lifecycle, sizeThatFits, font-design inheritance, animation suppression, and the small set of legitimate use cases. Use this skill whenever the swiftui-native-first skill points you here for a documented escape hatch.
The single most important quality skill. Enforces native SwiftUI components and rejects unnecessary custom code. Use this skill as a reference throughout the entire build process. Include its core rules in every CLAUDE.md. This is what prevents Claude Code from building janky custom UI when a native component exists.
