Prompt Engineering Impact

Across eight prompting techniques in this illustrative scenario, accuracy ranges from 62 on zero-shot queries to a high of 91 for multi-step decomposition, with jurisdiction-scoped prompts scoring highest on relevance (92) and structured-output prompting leading on completeness (90). Chain-of-thought and role-based framing land in the middle of the pack. The spread suggests query structure, not just model choice, is a meaningful lever for output quality - pointing legal teams toward prompt design and jurisdiction-scoping as a lower-cost improvement path than model switching. These figures are illustrative, not measured benchmarks.
