Step 1
A prompt is what you typed. A workflow is how you do the job again.
Do not stop at "that answer was pretty good." If the task will come back, save the recipe. The recipe is what makes AI feel useful instead of random.
Prompt only
"Write a reply to this customer." It worked once, but next time you still have to explain the tone, format, and rules.
Workflow
"Use my customer reply workflow." It already knows the job, the inputs, the tone, the format, and what to check.
