Refinement is a conversation. Small, specific requests beat long lists every single time.
Describe the change by outcome, not by instruction: 'the birthday list should show the next six months, closest first' rather than 'sort the array'.
One request, one review. When you bundle five changes together and something breaks, you no longer know which one caused it.
If the AI misunderstands twice, the problem is usually the description, not the model. Rewrite the request more concretely.
Practice
Keep a short list of pending changes and work down it one line at a time.
Try this
Rewrite your last failed request as a description of the finished result.
