Estimated time: 2–4 hours per featureUpdated: 28 September 2026

Use this guide when you want to add a real feature, such as user sign-up, search or a report, to an existing project with an AI assistant's help. Have your project under version control, your tests running and a clear description of what the feature should do.

Step by step

  1. Write a short feature description

    Describe what the feature does, who uses it and how you will know it works, in a few sentences. Include examples of expected inputs and outputs. This description becomes the context you give the AI in each prompt.
