Concept

Prompt Engineering Masterclass: treat models as probabilistic teammates. Reliability comes from evals, constraints, retrieval, and human checkpoints — not vibes.

Why it matters

AI features that cannot be measured get worse in production. Founders who instrument quality ship durable leverage.

Action steps

  1. 1Specify the user job and success criteria before picking a model.
  2. 2Build a golden set of 20-50 eval examples for the critical path.
  3. 3Start with the simplest stack (prompt + tools) before multi-agent complexity.
  4. 4Log prompts, outputs, latency, and cost per successful task.
  5. 5Add guardrails for PII, jailbreaks, and hallucinated actions that spend money.
  6. 6Ship to a narrow cohort; compare against a non-AI baseline.

Done when

You have evals green on the golden set and a production path with cost caps.

Metrics

  • · Task success rate
  • · Cost per successful task
  • · Latency p95
  • · Human override rate

Anti-patterns

  • · Agents without evals
  • · Putting secrets in prompts
  • · Ignoring cost until the bill arrives
Operator tip

If you cannot define correct, you cannot ship AI. Write the rubric first.
