Record screen, microphone or camera from macOS terminal

macOS CLI tool to record microphone audio, screen video or screenshot, and camera video or photo from the terminal with device listing and output control.

Security Scan

The skill's instructions, required resources, and behavior are consistent with a macOS command‑line recording tool; it requests no unrelated credentials or file access. The only caution is that the README suggests installing from a third‑party Homebrew tap — verify that before running the installer.

Purpose & Capability

The name and SKILL.md describe a CLI for audio/screen/camera capture and the documented commands, options, and permission notes match that purpose. There are no requested environment variables, credentials, or config paths that don't relate to recording.

Instruction Scope

The runtime instructions stay within the stated scope: how to run subcommands, list devices, choose outputs, and handle macOS privacy permissions. The guide explicitly requires user consent before recording and advises using --duration for non-interactive runs, reducing scope creep.

Install Mechanism

There is no formal install spec in the skill bundle (instruction-only), which is low risk. The SKILL.md suggests 'brew install atacan/tap/record' — a third-party Homebrew tap. That recommendation is reasonable for a CLI tool but carries trust risk if users blindly run the command; verify the tap and inspect the package source before installing.

Credentials

The skill requires no environment variables, credentials, or config paths. All options relate directly to recording (device selection, output path, formats). There is no unexplained request for secrets or unrelated service access.

Persistence & Privilege

The skill does not request persistent presence (always:false) and has no installable components in the bundle. It does not modify other skills or system-wide settings. Normal autonomous invocation is allowed by platform default but not raised by the skill itself.

Assessment

This skill is internally consistent with a macOS recording CLI and does not ask for unrelated credentials. Before installing or running anything mentioned here: (1) do not run the brew install line without verifying the Homebrew tap (atacan/tap) and inspecting its package/source code, (2) ensure you explicitly grant terminal privacy permissions only if you trust the binary, (3) always confirm with the user before recording (the SKILL.md correctly recommends this), and (4) if an agent will run the tool autonomously, limit invocation to explicit, user-approved tasks to avoid accidental recordings.

record CLI

A macOS command-line tool for recording audio, screen, and camera output. Designed for both human users and AI agents operating in a terminal.

Output file paths are printed to stdout. Status messages go to stderr, making the tool pipeline-friendly.

IMPORTANT: User Consent Required

Always ask the user for explicit permission before running any recording command. Recording audio (microphone), screen, or camera captures sensitive data and may be unexpected. Before executing record audio, record screen, or record camera, confirm with the user that they intend to record, what will be captured, and the duration. Listing devices (--list-devices, --list-displays, --list-windows, --list-cameras) and taking screenshots (--screenshot) are less intrusive but should still be confirmed if not explicitly requested.

Installation

brew install atacan/tap/record

Quick Reference

# Audio
record audio --duration 10                    # Record 10s of audio
record audio --duration 5 --json              # JSON output with file path

# Screen
record screen --duration 5                    # Record screen for 5s
record screen --screenshot                    # Take a screenshot
record screen --screenshot --output /tmp/s.png

# Camera
record camera --duration 5                    # Record webcam for 5s
record camera --photo                         # Take a photo

Subcommands

Subcommand	Purpose
record audio	Record from microphone
record screen	Record screen video or take a screenshot
record camera	Record from webcam or take a photo

Each subcommand has its own --help flag with full option details.

Key Patterns for AI Agents

Get the output file path

The tool prints the output file path to stdout. Capture it:

FILE=$(record audio --duration 5)
echo "Recorded to: $FILE"

Use --json for structured output

All subcommands support --json to emit machine-readable JSON to stdout:

record audio --duration 5 --json

Use --duration for non-interactive recording

Without --duration, the tool waits for a keypress to stop (requires a real TTY). AI agents should always pass --duration <seconds> to ensure the command terminates.

List available devices

record audio --list-devices
record screen --list-displays
record screen --list-windows
record camera --list-cameras

Add --json for structured output.

Control output location

record audio --duration 5 --output /tmp/recording.m4a
record screen --screenshot --output /tmp/screen.png --overwrite

Without --output, files are saved to a temporary directory.

Screen recording with audio

record screen --duration 10 --audio system    # system audio only
record screen --duration 10 --audio mic       # microphone only
record screen --duration 10 --audio both      # system + mic

Capture a specific window or display

record screen --screenshot --window "Safari"
record screen --duration 5 --display primary

macOS Permissions

The terminal app (Terminal, iTerm2, etc.) must have the relevant permission enabled in System Settings > Privacy & Security:

• Microphone - for record audio and record camera --audio
• Screen Recording - for record screen
• Camera - for record camera

Troubleshooting

If a command fails or behaves unexpectedly, run:

record <subcommand> --help

The --help output always reflects the installed version and is the authoritative reference.
