Simple account-only Bluesky labeler

This is a very barebones Cloudflare Worker which acts as a Bluesky labeler service.

It omits some features like signatures and support for the queryLabels endpoint, but seems to work just fine with the native bsky.app web and iOS app.

The idea behind this is to be simple and avoid the complexity present in full featured labelers, which include a database and a full server that responds to HTTP requests. I hope you can use this as a good starting point, it should be fairly easy to translate it to other languages/frameworks too if necessary.

The below sections explain how to set up your account as a labeler and how to deploy this worker. These steps are fairly simple and you should have a working within 5 minutes.

Account setup

1. Create a new Bluesky account (do not reuse a personal account for this!)
2. Run npx @skyware/labeler setup and follow the wizard to convert that account into a labeler
3. The URL of the labeler will be https://bsky-labeler.<YourUsername>.workers.dev/.
4. The label we use in this example is verified-human. You can easily change this though.

Worker deployment

Once your account is set up properly, you can deploy your worker by running wrangler deploy in this repo's directory.

Testing the labeler

You should then be able to test your new labeler by subscribing to it (just go on its profile), then if you view the profile for bsky.app you should see the new label.
