WSL2 Clipboard Fix Setup

Use this skill when the user asks to set up, configure, or troubleshoot WSL2 image pasting in Claude Code.

When to Use

• User mentions image paste not working in WSL2
• User asks to set up wsl-clipboard-fix
• User asks about pasting images in WSL

When NOT to Use

• User is on native Linux (not WSL)
• User is on macOS or Windows (not WSL)

Setup Steps

Step 1: Verify WSL2 Environment

Check that the user is running WSL2:

# Should show Microsoft in version string
grep -qi microsoft /proc/version && echo "WSL detected" || echo "Not WSL"

# Should show WSLInterop
ls /proc/sys/fs/binfmt_misc/WSLInterop* 2>/dev/null && echo "WSL2 confirmed" || echo "WSL1 or not WSL"

Step 2: Install Dependencies

Two packages are required:

sudo apt update && sudo apt install -y wl-clipboard imagemagick

Verify:

wl-paste --version
convert --version | head -1

If wl-paste cannot connect to Wayland, ensure WSLg is working:

echo $WAYLAND_DISPLAY  # Should show "wayland-0" or similar
ls /mnt/wslg/runtime-dir/wayland-0 2>/dev/null && echo "WSLg OK" || echo "WSLg not available"

Step 3: Verify Plugin Hook

The plugin automatically starts the clip2png watcher on session start. Verify it works:

# Test manual conversion
"${CLAUDE_PLUGIN_ROOT}/scripts/clip2png" --once

# Check daemon status
"${CLAUDE_PLUGIN_ROOT}/scripts/clip2png" --status

Step 4: Configure Keybinding (Optional but Recommended)

Windows Terminal intercepts Ctrl+V for text paste. To paste images in Claude Code, bind Alt+V:

Create or edit ~/.claude/keybindings.json:

{
  "bindings": [
    {
      "context": "Chat",
      "bindings": {
        "alt+v": "chat:imagePaste"
      }
    }
  ]
}

Important: The file must have an object with a bindings array at the top level, NOT a bare array.

Step 5: Test

1. Copy an image on Windows (e.g., screenshot with Win+Shift+S, or right-click an image and Copy)
2. Wait ~2 seconds for the watcher to convert BMP to PNG
3. Press Alt+V (or your configured key) in Claude Code
4. The image should paste successfully
