You run Claude Code and Codex in a bunch of terminal tabs. Then you quit the terminal, macOS installs an update, or the laptop reboots. The tabs come back empty, and you're left guessing which `claude --resume` or `codex resume` belonged where.

With undead, every restored tab continues its exact conversation by itself. No command to run, no picker, no guessing. It should feel like you never quit.

Highlights

• Every restored tab resumes its own session, in its folder, with the flags you started it with.
• Claude Code and Codex, side by side in the same terminal.
• iTerm2 tabs and split panes, and Terminal.app.
• No daemon, no polling, no typing into a running agent, and no dependencies beyond macOS itself.
• Works for the sessions already running when you install it, without restarting a single tab.
• Never adds a flag you didn't use. A session you closed stays closed; one killed by quitting the terminal comes back.

Installation

macOS with zsh (the default shell), and iTerm2 or Terminal.app.

brew install dimabalony/tap/undead
