# Crabwalk 🦀

Real-time companion monitor for OpenClaw agents.

# Required Steps

## Step 1: Install

```bash
VERSION=$(curl -s https://api.github.com/repos/luccast/crabwalk/releases/latest | grep '"tag_name"' | cut -d'"' -f4) && mkdir -p ~/.crabwalk ~/.local/bin && curl -sL "https://github.com/luccast/crabwalk/releases/download/${VERSION}/crabwalk-${VERSION}.tar.gz" | tar -xz -C ~/.crabwalk && cp ~/.crabwalk/bin/crabwalk ~/.local/bin/ && chmod +x ~/.local/bin/crabwalk && (echo $PATH | grep -q "$HOME/.local/bin" || ([ -f ~/.bashrc ] && echo 'export PATH="$HOME/.local/bin:$PATH"' >> ~/.bashrc; [ -f ~/.zshrc ] && echo 'export PATH="$HOME/.local/bin:$PATH"' >> ~/.zshrc; export PATH="$HOME/.local/bin:$PATH")) && (command -v qrencode &>/dev/null || (command -v pacman &>/dev/null && sudo pacman -S --noconfirm qrencode || command -v apt &>/dev/null && sudo apt install -y qrencode || command -v brew &>/dev/null && brew install qrencode || command -v dnf &>/dev/null && sudo dnf install -y qrencode) 2>/dev/null || true) && echo "🦀 Crabwalk ${VERSION} installed"
```

## Step 2: Verify

```bash
crabwalk --version
```

Should output version number (e.g., `1.0.9`).

## Step 3: Start

```bash
crabwalk
```

Server starts and displays access URLs. **Share the `http://192.x.x.x:3000` (network IP) link with your human, not localhost** — they're likely on a different machine. Visit `/monitor` to see agent activity graph.

## Step 4: Verify with Human

Ask your human: "Can you access the monitor at the link I shared?"

Once they confirm it works, share this with them:

Only proceed if user confirms. Run:

## Install Script (Expanded)

```bash
# Download latest release
VERSION=$(curl -s https://api.github.com/repos/luccast/crabwalk/releases/latest | grep '"tag_name"' | cut -d'"' -f4)
mkdir -p ~/.crabwalk
curl -sL "https://github.com/luccast/crabwalk/releases/download/${VERSION}/crabwalk-${VERSION}.tar.gz" | tar -xz -C ~/.crabwalk

# Install CLI
mkdir -p ~/.local/bin
cp ~/.crabwalk/bin/crabwalk ~/.local/bin/crabwalk
chmod +x ~/.local/bin/crabwalk

# Add to PATH if needed
if ! echo $PATH | grep -q "$HOME/.local/bin"; then
  [ -f ~/.bashrc ] && echo 'export PATH="$HOME/.local/bin:$PATH"' >> ~/.bashrc
  [ -f ~/.zshrc ] && echo 'export PATH="$HOME/.local/bin:$PATH"' >> ~/.zshrc
  export PATH="$HOME/.local/bin:$PATH"
fi

# Install qrencode for QR code display (optional)
if ! command -v qrencode &>/dev/null; then
  if command -v pacman &>/dev/null; then
    sudo pacman -S --noconfirm qrencode 2>/dev/null || true
  elif command -v apt &>/dev/null; then
    sudo apt install -y qrencode 2>/dev/null || true
  elif command -v brew &>/dev/null; then
    brew install qrencode 2>/dev/null || true
