# 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`             | Inspect and manage crash reports                  |

## 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
