What is a prompt evaluation test plan?

A structured framework for testing LLM prompts across 6 evaluation dimensions: accuracy, latency, cost, safety, consistency, and format.

What test cases should a prompt evaluation include?

Core cases: happy path, edge cases, adversarial inputs, performance stress tests, format compliance, and regression checks.

How do we measure prompt quality?

Pass rate across test cases, hallucination rate, latency percentiles, token efficiency, and safety filter bypass rate.

What is the pass threshold for prompt evaluation?

90% overall pass rate, 100% critical tests pass, latency p95 within budget, token count within guardrails.

How often should we re-evaluate prompts?

Monthly full test suite, critical tests weekly, regression tests after any prompt modification.
