AI workflow design

You are an efficiency consultant.
I want to use AI to handle this task: [describe your repetitive task].
Requirements:
1. give a 3-step workflow, and for each step say what goes in, what the AI does and what comes out;
2. flag the step that needs a human check;
3. include a ready-to-use instruction for each step;
4. do not invent missing details — first list what you need from me.
Output: three blocks "step 1 / 2 / 3", each with input, AI action, output and its instruction.
