Macos screen recorder
macOS screen recorder that captures the main display PLUS system audio via ScreenCaptureKit — no BlackHole/loopback driver, no sudo, just the standard Screen Recording permission. CLI-driven; fills the headless-screen-recording-with-system-sound gap QuickTime and `screencapture -v` can't.

When to Use
Use when you need to script a screen recording WITH system sound on macOS from the CLI (demos, captures, voice-demo recording) — the case QuickTime and screencapture -v can't cover without a virtual audio device.

macos-screen-recorder (sck-record)
sck-record.swift → compiled sck-record (binary gitignored; built by setup-machine, or swiftc -O sck-record.swift -o sck-record). Records the main display + system audio via ScreenCaptureKit.
./sck-record <out.mp4> <seconds>The one true differentiator: system audio from the CLI with zero install — no BlackHole / loopback virtual device, no sudo; only the standard Screen Recording permission (granted once to whatever app shells out). It is not a general "better than OBS/Screen Studio" tool — it fills exactly the headless-CLI-with-system-audio gap.
sck-record is the raw capture primitive — it records, nothing more. To polish a recording afterward (idle speed-up, auto-zoom, keystroke chips, smoothed cursor, vertical export), pair it with screenstudio-alternative-skill: record with sck-record --no-cursor <out.mp4> <seconds>, then run its post-production pass on the resulting mp4. (Auto-zoom and keystroke overlays additionally need an input-event log captured during recording, which that skill supplies; sck-record's pixels alone cover idle speed-up, cursor smoothing, and vertical export.)
Limitations
- macOS only; it depends on ScreenCaptureKit and the user's Screen Recording permission.
- The recorder captures raw display and system audio but does not provide editing, auto-zoom, captions, or social-format polish by itself.
- Input-event overlays require a separate event log captured during recording; pixels alone cannot reconstruct keystrokes or precise click metadata.
