Prompt Patterns That Survive Production

Getting an LLM to do something useful in the playground is easy. Keeping it reliable after ten thousand edge-case inputs, two model updates, and six months of real users is something else. This course teaches the small set of patterns that consistently hold up in production - and the failure modes that silently kill the ones that don’t.

1. Why Prompts Fail in Production

The playground-to-production gap. Four vectors that break prompts after deployment, and the engineering mindset for diagnosing them.

🔐

2. The Five Core Patterns

Role anchoring, explicit output constraints, chain-of-thought, few-shot format anchoring, and negative-space constraints - with before/after examples for each.

3. System Prompt Architecture

The four layers of a production system prompt, how to prevent user messages from overriding it, and why multi-turn conversations drift.

6. Failure Modes & Degradation

The five failure categories - instruction following, context confusion, refusals, hallucination, drift - and how to diagnose each in production.

7. Versioning & Regression Testing

Treating prompts as code: changelogs, regression test sets, LLM-as-judge evaluation, and CI/CD integration that blocks regressions.

8. The Production Patterns Checklist

The 25-point pre-deploy checklist, the pattern maturity model, the “is this prompt production-ready?” decision tree, and ten rules to remember.

What You Will Learn

By the end of this course, you will be able to:

🔐

Identify Reliable Patterns

Distinguish patterns that hold under production load from patterns that only work in demo conditions - and understand why.

📈

Enforce Output Consistency

Design prompts whose output a downstream parser can trust - even across model updates and unexpected user inputs.

🛠

Architect System Prompts

Build layered system prompts that maintain their behavioral guarantees across multi-turn conversations.

Test Before You Ship

Build a regression test set, evaluate with LLM-as-judge, and block deployments that silently regress.
