My experiments with agent-augmented dev feel like "coding by dictation", and always require manual review and MANY follow-ups. Code style: terrible. Naming things: terrible. Math: terrible. Forward-thinking design: terrible. Unsure if I'm more productive or less. 🫤

I occasionally want to close an experimental PR without losing the context and changes associated with it. Is there a better way than dumping a patch into comments as seen below? I don't want lingering topic branches.

Is there any standard in place for marking content with its level of AI contribution? Basically, a *standard* way to mark your content as fully human generated all the way up to fully AI generated. Doesn't seem like there's a good standard.

There are few conferences I have been to with such engaged and excited developers. Definitely worth your sponsorship.
