One month testing Devin

Devin was connected to the RunLLM GitHub repo and given small bug fixes and one larger full-stack task over a month.

Small scoped fixes took about five minutes to test and merge versus roughly an hour by hand; the full-stack task failed and was rewritten.

Overview

How it was set up

Devin connected to the GitHub repo, scanned it to infer build steps, and opened pull requests. Tasks were typed into its chat interface.

Worth knowing

Devin struggled with a multi-layer task, ignored taught practices, and its code was unworkable. Backend work went worse than frontend.
