+## Session Persistence (Experimental)
+
+Enable automatic session persistence to maintain Claude Code sessions across workspace restarts:
+
+```tf
+module "claude-code" {
+  count               = data.coder_workspace.me.start_count
+  source              = "registry.coder.com/coder/claude-code/coder"
+  version             = "1.4.0"

+  folder              = "/home/coder"
+  install_claude_code = true
+
+  # Enable tmux with session persistence
+  experiment_use_tmux                    = true
+  experiment_tmux_session_persistence    = true
+  experiment_tmux_session_save_interval  = "10" # Save every 10 minutes
+  experiment_report_tasks                = true
+}
+```
+
+Session persistence automatically saves and restores your Claude Code environment, including working directory and command history.
+
 ## Run standalone
 
 Run Claude Code as a standalone app in your workspace. This will install Claude Code and run it directly without using screen or any task reporting to the Coder UI.

Subject: [PATCH 04/13] feat: enhance tmux installation and session persistence
 configuration in claude-code module

- Added a function to install tmux using various package managers if not already present.
- Improved validation for session persistence requirements, ensuring tmux is enabled when persistence is requested.
- Streamlined the installation process for git and tmux plugins within the tmux session configuration.

Subject: [PATCH 09/13] fix: improve tmux session management in claude-code
 module

- Added configuration to save bash history and ensure tmux sessions are created only when they do not already exist.
- Streamlined the logic for starting Claude within existing sessions, enhancing user experience and session handling.
