Giorgi Dalakishvili shows how he runs separate work and personal Claude Code accounts side by side in herdr, a terminal multiplexer built for AI coding agents, by giving each account its own CLAUDE_CONFIG_DIR. After a restart, herdr's session restore brought agents back on the wrong account, because it relaunches them with the server's environment rather than the pane's. The fix is a small launcher script that sets the account's config directory before starting each named herdr session, so every pane and restored agent inherits the right account.
