I previously let an AI agent build an entire social media site in one day. It worked, but then it introduced a bug that neither I nor the agent could fix because I had no idea what the code did.

Now I want to rebuild it. I want to use AI again, but this time as an assistant – I’ll review every change, write tests together, and keep a clear plan.

Which AI tool would you recommend for this hybrid approach? How do you structure prompts to force the agent to explain before coding?

Also, do you think a couple of weeks is realistic to rebuild the site that has feature parity with Lemmy and a few extra features that the AI managed to build in a single day? Should I switch to a more manual approach with the agent only for boilerplate?

Any advice is appreciated. Thanks!
