Pick the right design pattern up front and begin by creating unit tests that describe the exact behavior of the classes you plan to implement. Do not let AI design your architecture. Work in small, modular components, write the implementation for each part, and run your full test suite continuously. Once all unit tests pass and the structure is stable, AI can assist with integration tests—but never earlier.

Maintain a strict, explicit prompt file that documents every detail of your project’s architecture, rules, naming conventions, boundaries, and design principles. AI should never generate or modify core implementations without your explicit approval.

Also ask your model to give you prompts that makes it more effective, all models think on different levels.
