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.
Optimize pull requests for quick approval and merging by ensuring clean diffs, comprehensive self-reviews, and structured documentation.
Frontend design entry point: direction, design system, visual philosophy. Use whenever building or touching the look of any web UI (components, pages, dashboards, React/Vue/HTML-CSS) or when the user says "make this look better", "fix the spacing/layout", or mentions styling, color, type, or polish.
Render the UI and prove it's balanced + usable: a deterministic layout audit (centroid / optical-center / pixel-oracle balance via explicit math + annotated screenshot) plus a vision-judged Nielsen usability audit by a separate fresh-eyes judge. The measurement layer taste-only design skills lack.
Automated visual tuning: a vision or video model rates rendered variants in a loop. Render several labeled variants into one artifact, ask the model to rate them and suggest better values, render the suggestions, ask it to pick the best, repeat until good — the model is the eye, you run the loop.
Human-in-the-loop web studio to tune AI-generated output by eye. Stand up a local interactive studio (sliders, pickers, drag handles) or an inline edit/highlight/comment annotation studio for prose & media, instead of guessing values or shipping a static comparison grid.
Open-source headless Screen Studio alternative: auto speed-up of idle, auto-zoom on click clusters, keystroke overlay chips, smoothed synthetic cursor, and 9:16 vertical export that follows the action — post-production for screen recordings from the CLI.

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.)
