03 Prompt Engineering

Phase 1 - Foundations
Stage 3 of 14. Previous: Stage 2 - LLM Fundamentals. Next: Stage 4 - Agent Fundamentals.

Goal

Learn to write, test, and improve prompts that produce reliable agent behavior.

Learn

• Prompt Basics
• Writing Good Prompts
• Structured Outputs
• Prompt Testing
• How to specify role, task, context, constraints, and output format

Build

Build a prompt testing lab with several prompts, test inputs, expected outputs, and scoring rules.

Exit Criteria

• You can write prompts with clear role, task, constraints, and output format.
• You can test prompt changes instead of guessing.
• You can use structured output formats when downstream code depends on the result.
