 Based on your evaluation, present the user's options conversationally. Be specific about what they have and what each option gives them.
 
 **If over SSH:**
-Tell the user tmux is their only practical option. If tmux is installed, recommend it. If not, recommend installing it (`apt install tmux` / `brew install tmux`). Mention that images will work if their local terminal supports sixel.
+tmux works immediately for pane splitting, but images are limited to sixel or ASCII art. Present the user with options:
 
-**If native/remote desktop with tmux available:**
+> "You're connected via SSH. Here are your options:
-Present tmux as the ready-now option. Optionally mention kitty as an upgrade for better image quality if they want to install it later.
+>
+> **Option A: tmux (works now)** — I can split panes via tmux. Images render via sixel if your local terminal supports it, otherwise ASCII art. No setup needed.
+>
+> **Option B: Install kitty on the remote host + use a remote desktop** — If you can access this machine via a remote desktop protocol (Chrome Remote Desktop, RDP, VNC, etc.), you could install kitty on the remote host and use it through the remote desktop session. This gives you the full experience: native splits, best image quality. Is remote desktop an option for you?
+>
+> **Option C: Both** — Set up tmux now for SSH sessions, and also install kitty on the remote host for when you connect via remote desktop. Best of both worlds."
 
-**If native/remote desktop in kitty:**
+If the user chooses B or C, install kitty on the remote host:
-Great — they get the best experience. Just need `allow_remote_control yes` in kitty.conf.
+- Linux: `curl -L https://sw.kovidgoyal.net/kitty/installer.sh | sh /dev/stdin`
+- After install: add `allow_remote_control yes` to `~/.config/kitty/kitty.conf`
+- Remind them: kitty's display features only work through a remote desktop session, not over SSH
+
+If the user chooses A or C, set up tmux as normal (Step 4 handles mouse config).
+
+**If native/remote desktop (sitting at the machine or RDP/VNC):**
+**Recommend kitty** — it gives the best experience (native splits, best image quality via kitty graphics protocol). Present it as the primary recommendation, with tmux as the quick-start alternative if they don't want to install anything new.
+
+However, warn about this caveat:
+> **Note:** If you install kitty and use it as your terminal, be aware that some AI CLIs (like `gemini`) may prompt for passwords or authentication tokens during setup. Kitty uses its own keyboard protocol which can interfere with password prompts in some CLI tools. If you hit issues with password/auth prompts not working in kitty, switch to your regular terminal for that step, then come back to kitty.
+
+Installation:
+- Linux: `curl -L https://sw.kovidgoyal.net/kitty/installer.sh | sh /dev/stdin`
+- macOS: `brew install --cask kitty`
+- After install: add `allow_remote_control yes` to `~/.config/kitty/kitty.conf`
+- Launch your AI CLI from within kitty to get the full experience
+
+**If already in kitty:**
+Great — they get the best experience. Just need `allow_remote_control yes` in kitty.conf. Note: existing kitty windows must be restarted for config changes to take effect.

+   If mouse is off or not set:

+   ```bash
+   grep -q "set -g mouse on" ~/.tmux.conf 2>/dev/null || echo "set -g mouse on" >> ~/.tmux.conf
+   ```
+   Without this, tmux intercepts mouse clicks and the user cannot interact with checkboxes, buttons, or inputs in the display pane.
+
+4. **If the user SSHes to remote machines** (detected by known_hosts having entries, or the user mentions remote work), **set up SSH ControlMaster** so the AI CLI can reuse the user's authenticated SSH connections without needing to re-enter passwords or touch physical keys:
+
+   Ask the user: "Do you SSH into remote machines as part of your work? If so, I can configure SSH connection multiplexing — this lets you authenticate once, and my SSH commands piggyback on your open connection without needing a password."
+
+   If yes:

+   mkdir -p ~/.ssh/sockets
+   chmod 700 ~/.ssh/sockets
+   ```
+
+   Check if ControlMaster is already configured:
+   ```bash
+   grep -q "ControlMaster" ~/.ssh/config 2>/dev/null && echo "Already configured" || echo "Not configured"
+   ```
+
+   If not configured, add to `~/.ssh/config` (create if needed):
+   ```bash
+   touch ~/.ssh/config
+   chmod 600 ~/.ssh/config
+   cat >> ~/.ssh/config << 'SSHEOF'
+
+   # Kitty-Workbench: SSH connection multiplexing
+   # First connection authenticates normally (password, key, etc.)
+   # Subsequent connections reuse the tunnel — no re-auth needed
+   Host *
+       ControlMaster auto
+       ControlPath ~/.ssh/sockets/%r@%h-%p
+       ControlPersist yes
+   SSHEOF
+   ```
+
+   Explain to the user how it works:
+   > **How this works:** When you SSH into a remote machine, the connection stays open in the background for 10 minutes (`ControlPersist yes`). During that time, any other SSH command to the same host — including ones I run — reuses your authenticated tunnel. No password prompt, no key tap. The tunnel stays open until the original session closes or the connection drops — your key/auth provider handles its own timeout. Just open an SSH session to your target machine before asking me to work on it.
+
+   If the user's `~/.ssh/config` already has Host-specific blocks, add the ControlMaster settings under a `Host *` block at the **end** of the file so it acts as a default without overriding specific host configs.
+
+5. **Optional: install chafa** for ASCII art image fallback:
    - Linux: `sudo apt install chafa` or `sudo pacman -S chafa`
    - macOS: `brew install chafa`
