Steps

  1. Provide sample data and request a defined output: a spreadsheet with formulas, a document or a presentation. Specify columns, units and the audience.
  2. Ask Claude to separate original data, calculations and assumptions. Missing values should be stated, not invented.
  3. Open the generated file. Check spreadsheet formulas and totals, slide text clipping, and document headings and page order.
  4. If code is generated, inspect what it reads and writes before running it. Use a copy and check the output against your request.
Common pitfall: Successful file creation does not prove content, formulas or layout are correct.
Hands-on exercise: Request a small spreadsheet with three rows and a total. Open it and calculate the total independently.
