It wraps tmux to give you named, directory-scoped sessions with automatic context restoration via `claude --resume`. Start with `clux new api`, detach whenever, `clux attach api` later. Survives terminal crashes, reboots, whatever.
Has a TUI for browsing sessions and a streaming API (`clux prompt api "run the tests" --json`) that outputs NDJSON in real-time. I use it to control sessions from a Telegram bot.
Python, ~2k lines. Only needs tmux and the Claude CLI.
