Cmux Debugging
A debugging companion for cmux that covers the whole diagnostic workflow: tailing the unified debug event log, using the Debug menu for visual iteration, and navigating runtime pitfalls like typing-latency-sensitive code paths. The skill documents where key, mouse, and focus events are logged, how to add debug probes without introducing performance regressions, and specific SwiftUI gotchas around hit testing, list snapshot boundaries, and equatable body optimization. Reach for this when adding instrumentation, diagnosing UI responsiveness issues, or touching terminal rendering, drag/drop UTTypes, or tab/sidebar list views. The runtime pitfalls section alone will save you from subtle performance traps and OS-version-specific behavior changes.

Debug event log
Put debug event instrumentation (keys, mouse, focus, splits, tabs) in the unified DEBUG build log. This is not a requirement to log every new code path; most probes belong to a dogfood debug loop and are removed before merge.
tail -f "$(cat /tmp/cmux-last-debug-log-path 2>/dev/null || echo /tmp/cmux-debug.log)"
