A macOS command-line toolkit for controlling common system settings from Terminal, such as volume, Wi‑Fi, battery, display brightness, Dock, Bluetooth, and power.

It helps with checking system status, changing sound or brightness, managing networks and Bluetooth, adjusting the Dock, emptying Trash, locking the Mac, and restarting or shutting down.

It avoids opening separate macOS settings panels for routine checks and changes. You can use short commands for these tasks.

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.

Model	Per session	Once invoked
Fable 5	$0.00035	$0.00455
Opus 5	$0.00017	$0.00228
Sonnet 5	$0.00007	$0.00091
Haiku 4.5	$0.00003	$0.00046

Security

Grade B, and why

c-system scanned grade B with 1 finding 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 4d 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.

Asks for rootmediumPrivilege escalation

A mod that escalates privileges can change anything on the machine, not only the project.

- `m` requires no auth for most commands; some need sudo - Always confirm before `m restart`, `m shutdown`, or `m trash clean`

What it actually says

System Control (m-cli)

Swiss Army Knife for macOS. Run m followed by a category:

# Volume
m volume 50          # Set volume to 50%
m volume mute        # Mute
m volume unmute      # Unmute

# WiFi
m wifi status        # Show WiFi status
m wifi scan          # Scan available networks
m wifi connect SSID PASSWORD
m wifi off           # Turn WiFi off
m wifi on            # Turn WiFi on

# Battery
m battery status     # Battery percentage and state
m battery cycle      # Battery cycle count

# Display
m display status     # Display info
m display up         # Increase brightness
m display down       # Decrease brightness

# Dock
m dock addblank      # Add blank space to dock
m dock autohide YES  # Enable auto-hide
m dock magnification YES

# Trash
m trash clean        # Empty trash
m trash status       # Show trash size

# Bluetooth
m bluetooth status
m bluetooth on
m bluetooth off

# Network
m network ls         # List network interfaces
m network location   # Show current location

# Power
m nosleep           # Prevent sleep (until Ctrl+C)
m restart           # Restart Mac
m shutdown          # Shut down Mac
m screensaver       # Start screensaver
m lock              # Lock screen

# Finder
m finder showpath YES    # Show full path in title
m finder showhidden YES  # Show hidden files

# Firewall
m firewall status
m firewall enable

Guidelines

m requires no auth for most commands; some need sudo
Always confirm before m restart, m shutdown, or m trash clean
Use m wifi instead of raw networksetup commands
Use m volume instead of osascript for volume control

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.

c-system is a skill published in the GitHub repository daxaur/openpaw (167 stars, last pushed 3mo ago), licensed MIT. It adds 35 tokens to every session and 455 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it B with 1 finding (asks for root). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
