Prompting for Deterministic Business Logic (ANSWERED)
Hybrid designs where LLMs handle language but calculators, rules engines, and APIs enforce deterministic outcomes.
TL;DR — Quick Answer
Deterministic business logic — pricing, eligibility, compliance thresholds — belongs in code or rules engines, not free-form prompts. Use LLMs to gather parameters, explain outcomes, and format responses while backend services compute authoritative decisions. Prompts should reference rule outcomes, never replace them.
