Developer shares prompt engineering contract to ensure deterministic AI outputs

A developer audited 27 AI prompts and found that 22 were ineffective because they lacked clear instructions and defined outcomes. The prompts often described a general vibe rather than a specific task, allowed the model to fill in missing information with plausible but incorrect details, and failed to specify what a completed task should look like. The developer proposes a four-part contract-based prompt structure including ROLE, CONTEXT, CONSTRAINTS, and OUTPUT to ensure deterministic and reliable AI responses, particularly by preventing hallucination. AI

IMPACT Provides a practical framework for improving AI prompt engineering, leading to more reliable and deterministic AI agent behavior.

RANK_REASON Developer shares personal experience and a proposed framework for improving AI prompts, rather than announcing a new product or research.
