rec

A macOS screen recorder that captures the whole screen and computer audio into a MOV video file. It can also record a microphone, a webcam picture-in-picture, or one selected app's audio.

In plain words
What is it for?
Use it to record tutorials, demonstrations, app sessions, or presentations with system sound, voice, webcam footage, and optional subtitles.
Why use it?
It removes the need to configure separate audio-routing tools before recording. Optional processing can also flatten audio, transcribe speech, and add permanent subtitles.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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

rec 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 2d 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 rec launcher on $ARGUMENTS.

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

/Users/esaruoho/work/apple/bin/rec $ARGUMENTS
  • /rec — whole screen + all system audio → ./<timestamp>.mov (current folder)
  • /rec --app Renoise — screen + ONLY that app's audio
  • /rec --mic — start with the microphone recording too (2nd track) + auto YouTube -flat.mov
  • /rec --pip — bake the webcam in as a circle in the corner (speaking head)
  • /rec --mic --pip --burn — the whole pipeline in one command: record → flatten → transcribe (on the Mini) → burn subtitles → -subtitled.mov (add --burn-local to transcribe on this mac instead)
  • /rec --reveal — reveal + select the finished file in Finder
  • /rec --pip-square / --pip-corner tl|tr|bl|br / --pip-scale 0.16 — PiP tweaks
  • /rec --out ~/foo.mov — custom path · /rec --list — displays + audible app names

Press Ctrl-C to stop and finalize. Toggle the mic on/off mid-recording with kill -USR1 $(pgrep -n screen-audio-record). Thin wrapper over bin/screen-audio-record --system-audio; --app overrides (single-app audio wins). Same recorder the AppleToolbox 🧰 ▸ Record Screen & Audio toggle (⌃⌥⌘R) drives — there the mic live-toggle is ⌃⌥⌘M and files land in ~/Movies.

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.
