Prompt Engineering Crash Course
Learn how to design, test, and operate reliable prompts for large language model (LLM) applications in two weeks. This practical course moves from clear single-turn instructions to structured outputs, multi-step workflows, evaluation, security, and prompt management.
What You Will Learn
Rather than treating prompts as clever wording, the course treats them as versioned application behavior: define a task, supply the right context, constrain the output, measure results, and iterate against observed failures.
Crash Course Outcomes
- Explain what prompt engineering can improve and when prompting alone is not the right solution
- Write clear prompts that define a role, task, context, constraints, and output contract
- Select among zero-shot, few-shot, reasoning, decomposition, and tool-use patterns
- Produce machine-consumable structured outputs and handle invalid or incomplete responses
- Design a lightweight prompt evaluation set with task-relevant quality, latency, and cost measures
- Defend a prompt-based application against prompt injection and unsafe instructions
- Version, test, observe, and improve a production-minded prompt workflow
Recommended Audience
- Beginner: Product builders, analysts, and engineers who use LLMs but want repeatable results
- Intermediate: Application developers building summarization, extraction, classification, or assistant features
- Advanced: Applied AI practitioners responsible for prompt quality, reliability, safety, and cost in production
Prerequisites and Format
- Basic familiarity with LLM chat interfaces; programming is helpful but not required for the core lessons.
- Plan for roughly 4–6 hours each week: short readings, prompt experiments, and one practical deliverable.
- Use a low-risk, non-sensitive sample dataset. Never place credentials, private customer data, or unredacted production data in a prompt experiment.
- Go through Choosing between rules, ML, and GenAI first if you are unsure whether a prompt-based solution is appropriate for your problem.
Week 1: Design Clear, Testable Prompts
Core PromptingGoals:
- Turn ambiguous requests into explicit task specifications
- Control response structure and use examples effectively
- Apply prompt patterns to common language tasks
Syllabus:
- What prompt engineering is?
- The anatomy of a robust prompt: instruction hierarchy, task, context, constraints, examples, and a clear output contract
- Model settings and their trade-offs: temperature, sampling, token limits, determinism, latency, and cost
-
Zero-shot prompting for classification, extraction, rewriting, summarization, and transformation; identify when adding examples is unnecessary or harmful
-
Few-shot prompting: choosing representative examples, keeping labels consistent, avoiding example leakage, and versioning example sets as data
-
Structured outputs: schemas, allowed values, validation, repair loops, and when to fall back safely
- Iterative prompt design: form a hypothesis, make one change, compare outputs, and record the result
Week 2: Reason, Evaluate, Secure, and Operationalize
Prompt OpsGoals:
- Select advanced prompting patterns based on the task rather than novelty
- Evaluate prompt changes systematically
- Ship a safer, observable prompt workflow
Syllabus:
- Reasoning-oriented patterns: task decomposition, plan-and-solve, self-checking, and when hidden reasoning should not be requested or relied upon
-
Prompt chaining and routing: split complex work into narrow, observable stages; pass only necessary context between them; route by task, risk, latency, and cost rather than a fixed prompt alone
- Tool-aware prompts: define tool boundaries, validate arguments, distinguish tool output from instructions, and require confirmation for consequential actions
- Context selection: prioritize authoritative, current information; use retrieval for external knowledge rather than overloading a prompt
- Prompt evaluation: construct representative test cases; define accuracy, format-validity, safety, latency, and cost metrics; inspect failures by slice
- Prompt optimization and management: version templates, use regression tests, compare variants, and separate prompt configuration from application code
- Security and safety: identify instruction conflicts, prompt injection, data exfiltration risks, unsafe outputs, refusal behavior, and human escalation paths

This outline is designed to complement broader public curricula. For extra hands-on practice, work through DeepLearning.AI’s ChatGPT Prompt Engineering for Developers, which covers iterative prompting and common application patterns, and the DAIR.AI Prompt Engineering Guide, which provides technique references and model-specific guidance.
After completing the course, choose the next path according to the problem: deepen evaluation and observability for production applications, learn RAG for evidence-backed answers, or study AI agents when controlled tool use and multi-step task execution are genuinely required.
