screen-audio-record

A macOS command that records your screen and computer audio into a .mov video file. It can capture audio from one app or from the whole system without a microphone or virtual audio driver.

In plain words
What is it for?
Recording software demonstrations, music sessions, app tutorials, or any Mac screen activity with its original system audio.
Why use it?
It avoids extra audio-routing software and keeps computer sound separate from microphone input. You can stop the recording with Ctrl-C and finalize the file.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

screen-audio-record scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 3d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

Run the apple-skill screen-audio-record recorder on $ARGUMENTS.

Use Bash to execute (one call, then stop):

/Users/esaruoho/work/apple/bin/screen-audio-record $ARGUMENTS

Modes:

  • /screen-audio-record --list — list displays + audible running apps, then exit
  • /screen-audio-record --app Renoise --out ~/rec.mov — screen + ONLY that app's audio
  • /screen-audio-record --system-audio --out ~/rec.mov — whole display + ALL system audio
  • /screen-audio-record --app Renoise --mic --out ~/rec.mov — + your mic as a 2nd track
  • /screen-audio-record --system-audio --reveal — reveal the finished file in Finder
  • --display <n> picks a display from --list; --fps <n> sets frame rate (default 60)

Press Ctrl-C to stop and finalize the file. Toggle the mic on/off mid-recording with kill -USR1 <pid>. No BlackHole/Loopback needed — audio comes straight off the system audio engine via ScreenCaptureKit. Sequoia re-prompts screen-recording permission weekly / after reboot; approve iTerm once when asked.

After the command completes, report only the lines it printed.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
