Crabwalk ?

Real-time companion monitor for OpenClaw agents.

Required Steps

Step 1: Install

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

crabwalk --version

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

Step 3: Start

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:
