Problem Statement

The CLI supports conversation forking via --fork-session / /fork / /branch, and it's already been requested for the VS Code extension (#69272). The JetBrains plugin (IntelliJ/PhpStorm/WebStorm/etc.) has no equivalent — there's no way to branch a session at a given point from within the JetBrains tool window the way Cursor supports forking a chat.

Proposed Solution

Add /fork (or a UI action, e.g. a "Fork from here" option on a message) to the JetBrains plugin's Claude Code tool window, matching the CLI's forking behavior: branch the conversation at the selected point into a new session, preserving full history up to the fork point, while leaving the original session untouched.

Priority

Medium
