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 · Every loose type is an invitation the model will accept.

Step 2 · Make illegal states unrepresentable in the call.

Step 3 · The error message is the model's documentation at the moment it matters most.

Step 4 · Schemas regress silently unless tests hold the line.

•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.
