Problem

Scenario

You are building an LLM feature that reads messy text such as emails, notes, or support tickets and pulls out a fixed set of fields for downstream analysis. The main issue is reliability: the model may miss fields, invent values, or return output that is hard to parse.

Question

How would you design a prompt to reliably extract structured fields from text?

What This Tests

  • Prompt design for schema-constrained extraction
  • Handling missing or ambiguous fields without guessing
  • Reducing hallucinated values with evidence requirements
  • Making extraction quality measurable
