OhMyDebn Skill

Manage OhMyDebn Linux systems - a debonair Linux platform that combines the stability of the Debian distro, the ease of use of the Cinnamon desktop, and the beauty of Omarchy.

When This Skill MUST Be Used

ALWAYS invoke this skill when the user's request involves ANY of these:

• Editing ANY file in ~/.config/cinnamon/ (desklets, applets, extensions, panels, etc.)
• Editing ANY file in ~/.config/nemo/, ~/.config/gtk-3.0/, ~/.config/gtk-4.0/
• Editing terminal configs (alacritty, terminator, gnome-terminal, mate-terminal, xfce4-terminal)
• Editing ANY file in ~/.config/rofi/
• Editing ANY file in ~/.config/ohmydebn/
• Editing shell configuration files (~/.zshrc, ~/.config/zsh/, etc.)
• Window management, workspace behavior, panel configuration
• Desktop effects, animations, themes, wallpapers, fonts, appearance changes
• Any ohmydebn-* command (theme, pkg, reset-config, update, version)
• Screenshots, screen recording, power management, screensaver, startup applications
• Rofi launcher configuration and theming

If you're about to edit a config file in ~/.config/ on this system, STOP and use this skill first.

Critical Safety Rules

NEVER modify anything in /usr/share/ohmydebn/ - but READING is safe and encouraged.

This directory contains OhMyDebn's source files managed by the ohmydebn deb package. Any changes will be:

• Lost on next ohmydebn-update or package upgrade
• Cause conflicts with upstream
• Break the system's package management

/usr/share/ohmydebn/          # READ-ONLY - NEVER EDIT (reading is OK)
├── bin/                      # Source scripts (symlinked to PATH)
├── config/                   # Default config templates
└── install/                  # Installation scripts

Reading these directories is SAFE and useful - do it freely to:

• Understand how ohmydebn commands work: cat $(which ohmydebn-theme-set)
• See default configs before customizing: cat /usr/share/ohmydebn/config/cinnamon/cinnamon-settings
• Check stock theme files to copy for customization: ls /usr/share/ohmydebn-themes/
• Check original Omarchy themes: ls /usr/share/ohmydebn-themes/
• Reference default cinnamon settings from the config templates: cat /usr/share/ohmydebn/config/cinnamon/*

Always use these safe locations instead:

• ~/.config/ - User configuration (safe to edit)
• ~/.config/ohmydebn/themes/<custom-name>/ - Custom themes (must be real directories)

OhMyDebn Features:

• Desktop Effects: Enabled by default, disable via System Settings → Effects
• OpenCode AI: CLI (opencode-cli, Super + A) + GUI versions, update with ohmydebn-update-opencode
• Apps Menu: Rofi launcher, Super + Space or OhMyDebn Menu → Apps

System Architecture

OhMyDebn is built on:

Command Discovery

OhMyDebn provides commands following ohmydebn-<category>-<action> pattern.

# List all ohmydebn commands
ls /usr/share/ohmydebn/bin/ | grep ohmydebn-

# Find commands by category
ls /usr/share/ohmydebn/bin/ | grep ohmydebn-theme
ls /usr/share/ohmydebn/bin/ | grep ohmydebn-pkg

# Read a command's source to understand it
cat $(which ohmydebn-theme-set)

Command Categories

Configuration Locations

Cinnamon Desktop Environment

~/.config/cinnamon/
├── cinnamon-settings       # Main settings configuration
├── panels/                 # Panel configurations
│   ├── panel1/            # Bottom panel settings
│   └── panel2/            # Top panel settings (if enabled)
├── applets/               # Applet configurations
├── desklets/              # Desklet configurations
├── extensions/            # Extension configurations
└── background-chooser.log # Background selection logs

Key behaviors:

• Cinnamon auto-reloads most settings changes (no restart needed)
• Use Ctrl + Alt + Escape to restart Cinnamon desktop
• Use ohmydebn-reset-config to reset all configs to defaults

Nemo File Manager

~/.config/nemo/
├── nemo-actions          # Custom context menu actions
├── bookmarks             # Bookmarks
└── nemo_preferences      # File manager preferences

Nemo auto-reloads on config save.

GTK Theme Configuration

~/.config/gtk-3.0/
├── settings.ini          # GTK3 settings
└── bookmarks             # GTK bookmarks

~/.config/gtk-4.0/
└── settings.ini          # GTK4 settings

GTK applications reload themes automatically.

Alacritty (Default Terminal)

~/.config/alacritty/alacritty.yml    # Main configuration

The default terminal is Alacritty with:

• Caskaydia Nerd Fonts
• Zsh shell with Oh My Zsh
• Starship shell prompt
• Zoxide for smart cd command
• eza for beautiful directory listings
• bat for cat with syntax highlighting

Restart terminal applications by closing and reopening the window or using the application's restart functionality.

Other Terminals

~/.config/terminator/config
~/.config/gnome-terminal/
├── accels                # Keyboard shortcuts
├── profiles/             # Terminal profiles
└── settings              # General settings
~/.config/mate-terminal/

└── terminalrc            # Configuration

Other Configs

Safe Customization Patterns

Pattern 1: Edit User Config Directly

For simple changes, edit files in ~/.config/:

# 1. Read current config
cat ~/.config/cinnamon/cinnamon-settings

# 2. Backup before changes
cp ~/.config/cinnamon/cinnamon-settings ~/.config/cinnamon/cinnamon-settings.bak.$(date +%s)

# 3. Make changes with Edit tool

# 4. Apply changes
# - Cinnamon: auto-reloads most settings (no restart needed)
# - Rofi: auto-reloads on config save
# - Terminals: restart by closing and reopening window

Pattern 2: Make a new theme

1. Create a directory under ~/.config/ohmydebn/themes.
2. See how existing themes are done via:
   • /usr/share/ohmydebn-themes/ohmydebn/ for the native OhMyDebn theme
   • /usr/share/ohmydebn-themes/tokyo-night/ for original Omarchy themes (interpreted for Cinnamon)
3. Download a matching background (or several) from the internet and put them in ~/.config/ohmydebn/themes/[name-of-new-theme]
4. When done with the theme, run ohmydebn-theme-set "Name of new theme"

Pattern 3: Reset to Defaults -- ALWAYS SEEK USER CONFIRMATION BEFORE RUNNING

When customizations go wrong:

# Reset all configured apps to defaults (creates backup automatically)
ohmydebn-reset-config

# The reset-config command:
# 1. Backs up current configs with timestamp
# 2. Copies defaults from /usr/share/ohmydebn/config/
# 3. Restarts affected components

Common Tasks

Themes

ohmydebn-theme-list              # Show available themes
ohmydebn-theme-current           # Show current theme
ohmydebn-theme-set <name>        # Apply theme (use "Tokyo Night" not "tokyo-night")
ohmydebn-theme-next              # Cycle to next theme
ohmydebn-theme-bg-next           # Cycle wallpaper
ohmydebn-theme-install <url>     # Install from git repo

Theme Management:

• GUI: OhMyDebn Menu → Style → Theme or hotkey Ctrl + Super + T
• Background switching: Ctrl + Super + B or "Next Background" in menu
• Build custom themes: Ctrl + Shift + A (Aether theme builder)
• Install all Omarchy extra themes via menu option
• Browse Aether themes collection via menu option

Keybindings

Edit keyboard shortcuts through Cinnamon Settings or via cinnamon-settings keyboard. For manual editing:

~/.config/cinnamon/spices/keybindings/  # Custom keybinding configurations

View current bindings:

• gsettings list-keys org.cinnamon.desktop.keybindings
• Check /usr/share/ohmydebn/install/keybinding/*.txt for existing OhMyDebn bindings

IMPORTANT: When re-binding an existing key:

1. First check existing bindings in /usr/share/ohmydebn/install/keybinding/*.txt
2. Check if the key is already bound to avoid conflicts
3. Inform the user what the key was previously bound to

Example - rebinding Super+F (which may be bound to files by default):

# Check current binding
gsettings get org.cinnamon.desktop.keybindings "show-desktop"

# Set new binding
gsettings set org.cinnamon.desktop.keybindings.custom-keybinding:/org/cinnamon/desktop/keybindings/custom-keybindings/custom0/ name "Custom File Manager"
gsettings set org.cinnamon.desktop.keybindings.custom-keybinding:/org/cinnamon/desktop/keybindings/custom-keybindings/custom0/ command "nemo"
gsettings set org.cinnamon.desktop.keybindings.custom-keybinding:/org/cinnamon/desktop/keybindings/custom-keybindings/custom0/ binding "<Super>F"

Always tell the user: "Note: Super+F was previously bound to files. I've created a new custom keybinding."

Display/Monitors

Configure through Cinnamon Settings > Displays or via command line:

# List displays
xrandr

# Configure display (example)
xrandr --output eDP-1 --mode 1920x1080 --pos 0x0 --output HDMI-A-1 --mode 2560x1440 --pos 1920x0

Window Management

Cinnamon window management is configured through:

• Cinnamon Settings > Windows: Window behavior, tiling, workspaces
• Cinnamon Settings > Workspaces: Workspace configuration
• Manual editing: ~/.config/cinnamon/cinnamon-settings

For advanced window management, additional extensions can be installed from Cinnamon Spices.

Window Tiling

Basic Window Tiling:

• Super + Left/Right/Up/Down: Tile window to respective screen half
• Combine arrows for corner tiling (e.g., Super + Up then Right for upper right)
• No window gaps, maximizes screen area

Advanced Window Tiling (gTile Extension):

• Ctrl + Shift + G: Display gTile overlay
• Grid options: 2x2, 3x2, 4x4, or 6x6 (press 1, 2, 3, or 4 to select)
• Select tiles by pressing letter keys (e.g., 'a' then 'n' for left half in 4x4)
• Press same letter twice for single tile (e.g., 'a' twice for upper left corner)

gTile Hotkeys with Window Gaps:

• Ctrl + Shift + 1/2/3 (numpad): Bottom corners/half with gaps
• Ctrl + Shift + 4 (numpad) or H: Left half with gaps
• Ctrl + Shift + 5 (numpad) or Enter: Full screen with gaps
• Ctrl + Shift + 6 (numpad) or L: Right half with gaps
• Ctrl + Shift + 7/8/9 (numpad): Top corners/half with gaps

Configure gTile:

• System Settings → Extensions → gTile → Configure → Behavior tab

Fonts

Fonts are managed through Cinnamon Settings > Fonts, which provides options to:

• Change interface font, document font, monospace font, and window title font
• Adjust font rendering settings (hinting, antialiasing, scaling factor)
• Set font sizes for different UI elements

Caskaydia Nerd Font is included by default for terminal icons and glyphs.

OhMyDebn Utilities

Additional tools available in OhMyDebn:

• OhMyDebn Logo: Ctrl + Shift + O (display animated logo)
• OhMyDebn Demo: Ctrl + Alt + D (animated logo showcase)
• System Summary: GUI version of screenfetch via OhMyDebn menu or Ctrl + Shift + S
• System Monitoring: btop performance monitor via Super + T
• Audio Visualization: Cava via terminal or Ctrl + Super + A

System

ohmydebn-update                  # Full system update
ohmydebn-version                 # Show OhMyDebn version
ohmydebn-update-opencode          # Update OpenCode AI to latest

System control (lock, shutdown, reboot) is handled through:

• Cinnamon Menu (power options) or OhMyDebn Menu
• Hotkeys: Ctrl + Alt + L (lock), Ctrl + Alt + End (shutdown), Ctrl + Alt + Del (logout)
• Standard system commands: loginctl lock-session, shutdown now, reboot

Troubleshooting

# Reset all configured apps to defaults
ohmydebn-reset-config

# Full reinstall of OhMyDebn deb package
sudo apt install --reinstall ohmydebn

Decision Framework

When user requests system changes:

1. Is it a stock ohmydebn command? Use it directly
2. Is it a config edit? Edit in ~/.config/, never ~/.local/share/ohmydebn/
3. Is it a theme customization? Create a NEW custom theme directory
4. Is it a package install? Use apt or ohmydebn-pkg-install
5. Unsure if command exists? Search with ls /usr/share/ohmydebn/bin/ | grep ohmydebn

Development (AI Agents)

When contributing to OhMyDebn itself (e.g., fixing bugs, adding features), the install process is designed to be idempotent and can be run multiple times.

Update Process

When a user runs ohmydebn-update, it first installs the latest ohmydebn package and then goes through the install process again so they get the new changes. The install process is idempotent, meaning:

• It can be safely run multiple times without causing issues
• It will only apply new changes needed
• Existing configurations are preserved unless explicitly updated
• Dependencies are checked and installed as needed

Development workflow:

1. Make changes to the OhMyDebn source code in /usr/share/ohmydebn/
2. Test the changes by running the install scripts
3. Users get updates by running ohmydebn-update
4. The install process automatically handles applying new settings, dependencies, and configurations

Installation scripts in /usr/share/ohmydebn/install/ handle:

• Installing system dependencies via apt
• Setting up default configurations
• Creating necessary directories and symlinks
• Updating user configurations with new defaults
