Tmux Auto Attach

Auto-attach terminals to tmux sessions spawned by AI coding agents

Code https://github.com/florianbuetow/tmux-auto-attach

Tmux Auto Attach is a helper script that automatically attaches idle terminals to new tmux sessions spawned by your AI coding agent. The reason to spawn sub-agents, or agents from different vendors, in tmux sessions is observability and interoperability: you get a live window into what each sub-agent is doing, and sub-agents can be from any vendor (Anthropic, Google, OpenAI, …).

For a full walkthrough of how to use it, please read the blog post titled: Auto-attach to tmux Sessions Spawned by AI Agents.
