Key decision for this workflow

Use /promptbenchmark when the task is benchmark three prompts for extracting invoice fields; specify the evidence needed to accept the result.

Copy-ready task brief

/promptbenchmark Objective: Benchmark three prompts for extracting invoice fields Inputs: Ten anonymized invoices, ground-truth fields and three candidate prompts Deliverable: A scoring rubric for field accuracy, omissions, latency and formatting

Reusable prompt template

/promptbenchmark Objective: Benchmark three prompts for extracting invoice fields Available materials: Ten anonymized invoices, ground-truth fields and three candidate prompts Required output: A scoring rubric for field accuracy, omissions, latency and formatting Acceptance test: Use the same test set and output schema for all candidates; report per-field errors Boundary: Do not declare a universal best prompt from one small domain-specific test Return the requested deliverable first, then a brief verification checklist and any unresolved questions.
