Prompt Engineering as Code: Best Practices for Systematic LLM Output

This article introduces a structured methodology for prompt engineering, framing it as a software engineering discipline. The author proposes treating prompts as code, with principles including Plan-and-Prompt separation (separating planning from prompt execution), multi-stage generation pipelines for complex tasks, and version control for prompts. The guide covers patterns for simple Q&A to complex multi-step workflows, emphasizing testability and maintainability. This approach is valuable for teams integrating LLMs into production systems, as it provides a framework for consistent, high-quality outputs. The evergreen nature of these principles makes this a useful reference for engineers at any stage of LLM adoption.
