  1. Foundations of LLM Interaction

    4 weeks
    Goals
    • Understand how transformer-based LLMs process and generate text
    • Master basic prompt patterns: zero-shot, few-shot, instruction-based, and role-based prompting
    • Learn to read and interpret model API documentation across major providers
    • Build confidence writing clear, unambiguous natural-language instructions
    Resources
    • OpenAI Prompt Engineering Guide
    • Anthropic's Prompt Engineering Interactive Tutorial

    Milestone

    You can independently design effective prompts for simple tasks and explain why specific phrasing choices affect model behavior.

  2. System Prompt Architecture and Structured Output

    4 weeks
    Goals
    • Learn to design layered system prompts with role, constraints, formatting, and behavioral instructions
    • Master structured output engineering: JSON mode, function calling, schema enforcement
    • Understand context window management including token counting, truncation, and prioritization
    • Design prompts that maintain consistent persona and tone across long conversations
    Resources
    • LangChain documentation on ChatPromptTemplate and output parsers
    • OpenAI structured outputs and function calling guides
    • Anthropic's extended thinking and tool use documentation
    • Hands-on: Build a multi-turn customer support bot with strict JSON output
    Milestone

    You can architect a production-quality system prompt with structured outputs, role consistency, and context management.

  3. Testing, Evaluation, and Safety

    3 weeks
    Goals
    • Build systematic prompt evaluation frameworks with quantitative metrics
    • Learn to identify and mitigate prompt injection, jailbreaking, and data leakage risks
    • Use automated evaluation tools to benchmark prompt variants at scale
    • Implement guardrails and safety layers within prompt design
    Resources
    • Promptfoo documentation and tutorials
    • NeMo Guardrails getting-started guide
    • OWASP Top 10 for LLM Applications
    • Ragas and TruLens evaluation frameworks
    • Hands-on: Build a prompt regression test suite for an existing AI product
    Milestone

    You can evaluate prompt performance rigorously, identify security vulnerabilities, and implement safety guardrails.

  4. Advanced Patterns and Tool Integration

    4 weeks
    Goals
    • Design prompts for tool-use and function-calling workflows
    • Master RAG prompt optimization for retrieval-augmented generation pipelines
    • Learn cross-model prompt adaptation techniques

    Milestone

    You can design complex, tool-augmented prompt systems that work reliably across multiple LLM providers.

  5. Multi-Agent Orchestration and Production Systems

    5 weeks
    Goals
    • Design prompt architectures for multi-agent systems with role specialization
    • Implement production prompt lifecycle management including versioning, A/B testing, and rollback
    • Build monitoring dashboards for live prompt performance tracking
    • Develop organizational prompt governance frameworks and style guides
    Resources
    • LangGraph documentation for multi-agent workflows
    • CrewAI and AutoGen documentation
    • Weights and Biases experiment tracking for prompts
    • Hands-on: Design and ship a multi-agent prompt system to a staging environment with full observability
