According to God of Prompt on X, a 200+ test benchmark across ChatGPT, Claude, and Gemini shows that 'Context Stacking' consistently outperforms 'act as an expert' prompts for accuracy and consistency in reasoning and task execution. As reported by God of Prompt, the technique layers concise role, goal, constraints, examples, and evaluation criteria instead of asking the model to role-play, leading to higher fidelity outputs and fewer hallucinations in structured tasks. According to God of Prompt, this method improved instruction adherence and reduced prompt fragility in multi-step workflows, suggesting immediate business value for LLM-driven customer support, analyst work, and content operations where reliability and repeatability are critical.
