The commits are revealing.

Look at this one:

> Ask Claude to remove the "backup" encryption key. Clearly it is still important to security-review Claude's code!

> prompt: I noticed you are storing a "backup" of the encryption key as `encryptionKeyJwk`. Doesn't this backup defeat the end-to-end encryption, because the key is available in the grant record without needing any token to unwrap it?

I don’t think a non-expert would even know what this means, let alone spot the issue and direct the model to fix it.

That is how LLM:s should be used today. An expert prompts it and checks the code. Still saves a lot of time vs typing everything from scratch. Just the other day I was working on a prototype and let claude write code for a auth flow. Everything was good until the last step where it was just sending the user id as a string with the valid token. So if you got a valid token you could just pass in any user id and become that user. Still saved me a lot of time vs doing it from scratch.

I tend to disagree, but I don't know what my disagreement means for the future of being able to use AI when writing software. This workers-oauth-provider project is 1200 lines of code. An expert should be able to write that on the scale of an hour.

The main value I've gotten out of AI writing software comes from the two extremes; not from the middle-ground you present. Vibe coding can be great and seriously productive; but if I have to check it or manually maintain it in nearly any capacity more complicated than changing one string, productivity plummets. Conversely; delegating highly complex, isolated function writing to an AI can also be super productive, because it can (sometimes) showcase intelligence beyond mine and arrive at solutions which would take me 10x longer; but definitionally I am not the right person to check its code output; outside of maybe writing some unit tests for it (a third thing AI tends to be quite good at)

An expert in oauth, perhaps. Not your typical expert dev who doesn't specialize in auth but rather in whatever he's using the auth for. Navigating those sorts of standards is extremely time consuming.

Maybe, but also: Cloudflare is one of like fifteen organizations on the planet writing code like this. The vast majority of The Rest Of Us will just consume code like this, which companies like Cloudflare, Auth0, etc write. That tends to be the nature of highly-specialized highly-domain-specific code. Cloudflare employs those mythical Oauth experts you talk about.
