Notes

• Upstream agent-browser command-prefix usage is transformed to steel browser for migration-friendly examples.
• Runtime-specific env vars and config names (for example AGENT_BROWSER_*) are preserved as upstream runtime details.
• Steel-native lifecycle commands (steel browser start|stop|sessions|live) are documented in ./steel-browser.md.

JavaScript

steel browser eval -b "<base64>"             # Any JavaScript (base64 encoded)
steel browser eval --stdin                   # Read script from stdin

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

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

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