Module 2 · Prompting — getting a real answer Lesson 4 of 15
How Zapier reads what you type
Context, instructions and roles. Each step only sees the data the step before it produced, so the shape of the data between steps is the whole design problem. Understanding what the model can see — and what it has already forgotten — explains almost every disappointing answer you will get.
The concept
Each step only sees the data the step before it produced, so the shape of the data between steps is the whole design problem. This is the machinery. A model does not remember your last conversation the way a person does; it is handed text and asked to continue it well. Everything you want it to know has to be in that text, in the same window.
There is a difference between a system instruction — the standing context, set once — and a message, which is this request. Put your standing context in the standing place. "I am a final-year mechanical engineering student applying for data roles" belongs in your profile, not typed again at the start of every chat.
And there is a hard limit. When a conversation gets long enough, the earliest turns fall out of view. Symptoms: it contradicts an instruction you gave ten messages ago, or forgets the file you uploaded. The fix is a new conversation with a written summary of where you got to, not a longer argument.
Worked example
A form that collects a name as one field and an email as another needs one step to combine them before an email step can use them together.
Your practice task
Ask the same question twice: once on its own, once after a short paragraph of setup about who you are and what you need. Compare the two answers and write down the difference. That gap is the thing you are learning to control.
Do this before moving on. Reading a solution teaches the shape of it; typing it teaches you.
Key takeaway
Each step only sees the data the step before it produced, so the shape of the data between steps is the whole design problem.
