Which terminal emulators are supported?

Currently, Side Fork supports tmux and GNU Screen for automatic window creation and management.

Does this work with multiple Claude sessions?

Yes, you can fork any active session into a new terminal window as long as you are running within a supported terminal multiplexer.

How does Side Fork differ from the standard /fork command?

The standard /fork command replaces your current terminal session with the fork; Side Fork opens the new forked session in a separate tmux or screen window, keeping both active.

Is my session history preserved in the fork?

Yes, the fork inherits the entire conversation history of the current session up to the exact point the fork was created.

Can I use this without tmux or screen?

The automated window opening requires tmux or screen, but the script provides the manual command string to fork in other terminal environments.

Productivity & Workflow

Parallelizes Claude sessions by forking the current conversation into a new tmux or screen window for experimental branching.

The Side Fork skill enhances the standard Claude Code workflow by allowing users to create non-destructive experimental branches of their current AI session. Unlike the built-in fork command which replaces the current terminal instance, Side Fork opens a separate window in tmux or GNU Screen, enabling developers to pursue a new line of inquiry or code modification in parallel while maintaining the original context and progress in the primary terminal window. This is ideal for 'what-if' scenarios where you want to test a radical change without losing your current progress.
