Townie is fully open-source and itself runs on Val Town. Pull requests welcome!
To get Townie running in your Val Town account, click the **Remix** button and then add your ANTHROPIC_API_KEY. You can leave all the other environment variables blank.
Authentication in Townie is handled via Val Town Oauth. However, we have not yet opened up our OAuth to anyone else, which currently makes it very awkward to use your own Townie. Here is a temporary workaround:

        </ul>
        <p>
          The application proxies requests to the Anthropic API and Val Town API, allowing Claude to view and edit your
          project files directly.

You'll need to set up some environment variables to make it run.
- `ANTHROPIC_API_KEY` for LLM calls
- You'll need to follow [these instructions](https://docs.val.town/integrations/telegram/) to make a telegram bot, and set `TELEGRAM_TOKEN`. You'll also need to get a `TELEGRAM_CHAT_ID` in order to have the bot remember chat contents.
- For the Google Calendar integration you'll need `GOOGLE_CALENDAR_ACCOUNT_ID` and `GOOGLE_CALENDAR_CALENDAR_ID`. See [these instuctions](https://www.val.town/v/stevekrouse/pipedream) for details.
