Designing a Prompting Workflow for a High-Stakes, Multi-Step Task

You are deploying an LLM inside a corporate workflow to draft a first-pass analysis for a high-stakes internal decision memo (e.g., whether to approve a vendor contract). The input is a long, messy bundle of notes and constraints, and early pilots show two failure modes: (1) when asked directly, the model misses key constraints and produces confident but shallow conclusions; (2) when you add a generic “let’s think step by step” instruction, it produces lengthy reasoning but sometimes never states a clear final recommendation.

Write a proposed prompting workflow (you may describe it as a sequence of prompts) that uses: in-context learning with demonstrations, chain-of-thought prompting (including a zero-shot trigger where appropriate), least-to-most prompting, explicit problem decomposition, and an iterative self-refinement loop. Your answer must explain how these techniques work together (not independently) to reduce the two failure modes above, and must justify at least two tradeoffs you are making (e.g., latency/cost vs. accuracy, transparency vs. risk of overlong reasoning, fixed vs. dynamic decomposition). Conclude by giving one concrete example of a “final answer formatting” instruction you would include to ensure the model always outputs a clear recommendation at the end.
