From antigravity-awesome-skills
Records the main display plus system audio via ScreenCaptureKit from the CLI without virtual audio drivers or sudo. Fills the headless-recording-with-sound gap QuickTime and screencapture can't cover.

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.

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.)
npx claudepluginhub sickn33/antigravity-awesome-skills --plugin antigravity-bundle-aas-mobile-app-builderPolishes screen recordings via CLI: auto-idle speed-up, click-cluster zoom, keystroke overlays, smoothed cursor, and vertical 9:16 export. Requires Swift capture-side logger for full feature set.
Captures screenshots and videos of running macOS app windows via osascript, screencapture, and ffmpeg for UI verification, mockups, and visual comparisons in agent workflows.
Records microphone and system audio, transcribes to timestamped Markdown with speaker labels using whisper.cpp and Metal acceleration on macOS 14+. For meetings, notes, dictation.
