Agent of Empires: Run Claude Code, Codex, Gemini CLI, and Copilot Side-by-Side via tmux + Git Worktrees

GitHub·medium signal

Agent of Empires (1,145 GitHub stars, Rust) spawns isolated sessions for Claude Code, OpenCode, Codex CLI, Gemini CLI, and Copilot CLI in parallel tmux panes, each in its own git worktree. This operationalizes heterogeneous multi-agent routing at the filesystem level — different agents on different branches simultaneously, no conflicts. It's the infrastructure layer for the pattern practitioners have been building ad-hoc with tmux configs and shell scripts.
