Ghostty Skill

Overview

Ghostty is a fast, feature-rich, cross-platform terminal emulator that uses platform-native UI and GPU acceleration. It provides a CLI with +action commands for querying configuration, listing themes/fonts, validating config, and opening new windows via IPC. Window, tab, and split management are handled through keybind actions configured in the config file, not through CLI commands.

When to use: Configuring Ghostty themes, fonts, and keybinds; validating config files; querying available actions and themes; opening new windows from scripts; debugging terminal rendering issues.

When NOT to use: Managing other terminal emulators; tasks unrelated to terminal configuration.

Quick Reference

Task	Command / Config	Key Points
List CLI actions	ghostty +list-actions	Shows keybind actions, not CLI actions
List themes	ghostty +list-themes	Interactive TUI preview; --color=dark to filter
List fonts	ghostty +list-fonts	Uses Ghostty's font discovery
List keybinds	ghostty +list-keybinds	Add --default for defaults only
List colors	ghostty +list-colors	Named RGB colors available in config
Show config	ghostty +show-config	Add --default --docs for all options
Validate config	ghostty +validate-config	Check config file for errors
Edit config	ghostty +edit-config	Opens config in $VISUAL or $EDITOR
New window (IPC)	ghostty +new-window	Linux/GTK only via D-Bus; use -e for command
Run command	ghostty -e htop	Arguments after -e are the command
Set working dir	ghostty --working-directory=/path	Changes directory before running command
Custom config	ghostty --config-file=/path	Load additional config file
Check version	ghostty --version	Display version info
SSH terminfo	ghostty +ssh-cache	Manage SSH terminfo cache for remote hosts
Show font face	ghostty +show-face <codepoint>	Which font renders a specific Unicode codepoint
Crash reports	ghostty +crash-report

Common Mistakes

Mistake	Correct Pattern
Running ghostty +new-tab or +new-split as CLI commands	These are keybind actions, not CLI actions; configure them in the config file with keybind = ...
Running ghostty without full path when not symlinked on macOS	Use /Applications/Ghostty.app/Contents/MacOS/ghostty or create a symlink
Using +new-window on macOS expecting it to work	+new-window uses D-Bus IPC and only works on Linux/GTK
Editing config without reloading	Use the reload_config keybind action (default: ctrl+shift+comma on Linux)
Using --config-file with a relative path	Use absolute paths for --config-file to avoid resolution issues
Passing unknown actions without checking available list	Run ghostty +help to see CLI actions or +list-actions for keybind actions
Confusing CLI actions with keybind actions	CLI actions use +action syntax; keybind actions are configured via keybind = key=action in config

Delegation

• Discover available actions and themes: Use Explore agent to run ghostty +list-actions and ghostty +list-themes
• Automate terminal layouts: Use Task agent to script window creation and config changes
• Plan configuration changes: Use Plan agent to design keybind and theme configurations before applying

References

• CLI actions, flags, and IPC commands
