Final output

No inputs required — hit Run to stream each step in order.

Each step streams from its model and feeds the next. BYOK — you pay your provider directly. Add a key in Settings if a step needs one.

Step 1 · The architecture question is really a workload question.

Awaiting upstream steps…

Step 2 · Make the trade-offs visible before intuition locks in.

Step 3 · A design you can draw is a design you can build and debug.

Step 4 · Architectures are bets - set the tripwires that tell you the bet went bad.

•Recurring tasks you currently copy-paste between tools.
•When a single prompt isn't enough — you need a chain where output(n) feeds prompt(n+1).
•Fork and adapt if your inputs differ materially from the author's use case.
