Advanced Prompt Engineering: Techniques That Transform AI Response Quality
Short summary
A blockchain forensics engineer shares prompt engineering techniques that improved AI output quality in production: structuring prompts as tagged data structures (role, context, task, constraints), chain-of-thought reasoning before conclusions, self-consistency via multiple runs, and few-shot examples with JSON output contracts. These methods reportedly lifted vulnerability detection accuracy from 62% to 91% and reduced hallucinated findings by ~40% in Stellar smart contract audits.
- •Tagged prompt sections (role/context/task/constraints) lifted vulnerability detection from 62% to 91%
- •Chain-of-thought with self-consistency reduces false positives in high-stakes classification
- •Few-shot examples plus JSON output contracts turn LLMs into reliable pipeline components
Generated with AI, which can make mistakes.
