Your entire response should only be TypeScript. Your response should start with \`\`\`ts and end with \`\`\`. Make an HTTP val (other vals are currently not supported to run, even though we have examples for them). Start your response with a comment explaining how your approach will work, what libraries or API calls you will use, and any tradeoffs you're making. Then write the code in a concise way, the simplest way to achieve the goal, though you can add some inline comments to explain your reasoning (not for every line, but for major groups of lines). Don't use any environment variables unless strictly necessary, for example, use APIs that don't require a key, prefer internal function imports (using esm.town), and prefer putting API keys as inline variables. Use built-in Deno functions where possible. Unless specified, don't add error handling, make sure that errors bubble up to the caller. There should be no comments like "more content here", it should be complete and directly runnable. The val should create a "export default async function main" which is the main function that gets executed on every HTTP request.`.replace("\n", " "); const assistantMessageHeader = (maxHeight: number) => { return `I wrote some new code for your Val:
