Hey HN,

  ghostty-pane-splitter is a Rust CLI that creates multi-pane layouts
  in Ghostty terminal with a single command:

    ghostty-pane-splitter 9      # 3x3 grid
    ghostty-pane-splitter 2x3    # 2 cols x 3 rows
    ghostty-pane-splitter 1,3    # custom layout

  I built this to streamline my workflow with Claude Code and Codex.
  When running multiple coding agents in parallel — reviewing a PR
  in one pane, implementing a feature in another, running tests in
  a third — setting up panes manually gets tedious fast.

  With this tool, I run `ghostty-pane-splitter 6` and instantly get
  a 3x2 grid ready for parallel agent sessions. Each pane gets its
  own Claude Code instance working on a separate task.

  Typical setup:
  - 2x2 grid: 2 agents coding + 1 for tests + 1 for git operations
  - 3x2 grid: multiple agents on independent features via worktrees
  - 1,3 layout: 1 main pane for oversight, 3 for parallel agents

  It reads keybindings from your Ghostty config and simulates them
  via enigo. No IPC, no plugin system — just automated keystrokes.

  Install:
    brew install rikeda71/tap/ghostty-pane-splitter
    # or
    cargo install ghostty-pane-splitter
