Course Curriculum
10 Lessons
System Prompts, Personas & Zero-Shot Design
Learn how system prompts work, how to assign personas, design zero-shot instructions, and control output format — the foundation of reliable prompt engineering.
Persona-Based Assistants - Lab Exercises
Build three AI assistants with distinct personas — customer support agent, code reviewer, and technical writer — using the same underlying question to demonstrate system prompt power.
Few-Shot Prompting & Chain-of-Thought
Learn how to guide model behavior with example pairs, when chain-of-thought improves accuracy, and how to use self-consistency for reliable outputs.
Ticket Classifier with Few-Shot Examples - Lab Exercises
Build a support ticket classifier using few-shot examples that routes to engineering, billing, or sales with ≥85% accuracy on a 20-ticket test set.
Advanced Techniques: ReAct, Meta-Prompting & Prompt Chaining
Master advanced prompt patterns: ReAct for reasoning + tool use, meta-prompting for self-improvement, prompt chaining for complex pipelines, and injection defense.
Prompt Chain & Injection Defense - Lab Exercises
Build a three-stage NLP pipeline (summarize → extract entities → classify sentiment) and a prompt injection interceptor that blocks known attack patterns.
Prompt Optimization at Scale
Learn token efficiency techniques, eval-driven prompt improvement loops, A/B testing, prompt versioning, and compression strategies for production prompts.
Prompt Optimization Lab - Lab Exercises
Build a prompt optimizer that takes verbose baseline prompts, applies compression techniques, and measures quality retention via automated LLM-as-judge evaluation.
Capstone Briefing: Intelligent Document Processor
Review all prompt engineering techniques from the course and get briefed on the capstone document processing pipeline you'll build next.
Capstone Project: Document Processor
Build a three-stage document processing pipeline: entity extraction (few-shot), classification (CoT), executive summary (persona) — with injection guard and per-stage cost tracking.
