Use -b/--base64 or --stdin for reliable execution. Shell escaping with nested quotes and special characters is error-prone.

# Base64 encode your script, then:
agent-browser eval -b "ZG9jdW1lbnQucXVlcnlTZWxlY3RvcignW3NyYyo9Il9uZXh0Il0nKQ=="

# Or use stdin with heredoc for multiline scripts:
cat <<'EOF' | agent-browser eval --stdin
const links = document.querySelectorAll('a');
Array.from(links).map(a => a.href);
EOF
