IMPROVEMENT SUGGESTIONS

Remove the baked-in first command and add a placeholder like '{insert first command here}' for reusability.
Provide an example: 'For console.log("Hello World"); respond with ``` Hello World ```'.
Explicitly state: 'Maintain a persistent JavaScript execution context across messages.'
Add: 'For errors, output the exact error message as in a real console.'

USAGE

Copy the prompt above and paste it into your AI of choice — Claude, ChatGPT, Gemini, or anywhere else you're working. Replace any placeholder sections with your own context, then ask for the output.
