the most simple Claude Code setup found takes 5 minutes and gets 99% of the job done...

instead of one AI doing everything, you split it into three:

Agent 1, the Architect
> reads your request
> writes a technical brief
> defines scope and constraints

Agent 2, the Builder
> reads the brief
> builds exactly what it says
> nothing more, nothing less

Agent 3, the Reviewer
> compares the output to the brief
> approves or sends it back with specific issues

if rejected... the Builder fixes and resubmits

this loop catches things a single agent would never flag because it can't critique its own decisions (pair it with Codex using GPT-5.4 for best results)
