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.
Why this skill is useful
Adds a CLI tool for screen recording with system audio on macOS that isn't covered by existing tools, providing unique functionality.

What this skill does
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. Source: connerkward/macos-screen-recorder-system-audio (MIT). 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. Intended use: system audio from the CLI after a reviewed local build — 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.) Availability and capture scope This AAS tree contains the guide only: sck-record.swift, the compiled binary and setup-machine are not bundled. Obtain the exact reviewed upstream source/license and confirm OS/Swift/CLI support before compiling or claiming a recording. Existing permission alone does not authorize capturing the user's screen or system audio: confirm display/window, duration, destination and privacy scope. Use a new private output, hide unrelated sensitive surfaces, stop on schedule and inspect actual video/audio tracks before reporting success. …
