First-Principles Subtraction Review

Before calling the work done, revisit the goal and challenge weak assumptions and unnecessary complexity. Prioritize deletion, simplification, optimization, then automation, and leave good work unchanged.

Prompt
Think from first principles about what we are trying to achieve here. Before calling it done, review what you previously built: 1. Is anything here unnecessary, overly complex, or based on weak assumptions? Challenge those things. 2. What can be deleted entirely? 3. Now that the unnecessary parts have been removed, what can be simplified? Then make the changes. Prioritize deletion over simplification, simplification over optimization, and optimization over automation. It may already be done—you do not have to make changes. If it is good, leave it as it is.

Editor's note

Use this as a follow-up in the same conversation after an AI has completed an implementation. It asks the model to revisit the goal, remove unnecessary parts, and only then simplify what remains. The explicit permission to leave good work unchanged helps avoid changes made merely to show activity. For code projects, work within the existing authorization and use the relevant project checks to confirm that core behavior still holds.
