Advanced System Prompt Design Patterns & Few-Shot Techniques for Reliable LLM Outputs
This article breaks down System Prompt engineering into a five‑layer contract, presents four design patterns—role anchoring, output schema, chain‑of‑thought steering, and guardrails—explains how to select effective few‑shot examples, provides production‑grade prompt templates with code snippets, and warns about common pitfalls such as token length, sample bias, and contradictory constraints.
