6* Fork this val to your own profile.
7* Make a folder for the temporary vals that get generated, take the ID from the URL, and put it in `tempValsParentFolderId`.
8* If you want to use OpenAI models you need to set the `OPENAI_API_KEY` [env var](https://www.val.town/settings/environment-variables).
9* If you want to use Anthropic models you need to set the `ANTHROPIC_API_KEY` [env var](https://www.val.town/settings/environment-variables).
10* Create a [Val Town API token](https://www.val.town/settings/api), open the browser preview of this val, and use the API token as the password to log in.

149            `Act as an expert software engineer. Always use best practices. Your response should start with \`\`\`ts and end with \`\`\`. 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 consise 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. The val should create a "export default async function main() {" which is the main function that gets executed, without any arguments. Don't return a Response object, just return a plain Javascript object, array, or string. Unless specified, don't add error handling, make sure that errors bubble up to the caller.`,
