Workflow inputs

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 · Write down what every endpoint promises before testing it.

Step 2 · Fire real requests: does each endpoint honor its contract?

Step 3 · One error shape everywhere - safe, consistent, frontend-friendly.

Step 4 · Each failure class needs a visible, correct UI response.

Step 5 · Slowness is a failure mode - bound it and make it recoverable.

Best for

•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.
