Core Java for SDET Training Course - DevLabs Alliance

Oracle Certified Associate, Java SE 8 Program

*Introduction: Position CrewAI as an opinionated, higher-level framework for orchestrating role-playing autonomous agents.
*Core Abstractions: 
*Agents: Defined by role, goal, backstory, and tools.
*Tasks: The specific, descriptive assignments for each agent.
*Crews & Processes: How agents collaborate, focusing on Sequential and Hierarchical processes.

*Multi-Agent Collaboration: Design systems using the Agent Supervisor pattern, where one node acts as a manager that delegates tasks to specialized worker agents (other nodes or sub-graphs).
*Human-in-the-Loop: A critical pattern for safety and validation. Learn how to implement checkpoints in a graph where execution pauses and awaits human input or approval.
*Self-Correction Loops: Build graphs where one agent node critiques or reflects on the output of another, forcing a revision cycle until a quality threshold is met.
*Hands-on Lab 4: Building a Multi-Agent "Plan and Execute" Graph

*Problem Statement: Discuss the architectural limitations of a basic AgentExecutor. When do you need loops, conditional branching, human-in- the-loop validation, or multi-agent collaboration?
*Conceptual Introduction to LangGraph: Position LangGraph as a library for building robust agentic state machines. It provides the control and flexibility needed for enterprise-grade workflows.

*Concept: Moving beyond single-shot LLM calls to Agentic AI—systems that can perceive, reason, plan, and act to achieve a goal.
*Architectural Discussion: Contrasting traditional software architectures with agentic architectures. We will cover key challenges such as non-
determinism, state management, security, and observability.
*Introduction to LangChain: Positioning LangChain as a foundational framework for composing LLM applications.

*The Architect's Choice: A detailed discussion on when to use which framework.
*CrewAI: Ideal for rapid prototyping and use cases that fit a collaborative, role-playing model.
*LangGraph: The choice for ultimate control, complex custom state, fine-grained logic, and integrating human-in-the-loop workflows.
*Hands-on Lab 5: Building a Research Team with CrewAI

*State: The central, persistent memory of the graph. We will explore different ways to model state.
*Nodes: The functions or actions that manipulate the state.
*Edges: The directed connections between nodes, with a focus on Conditional Edges, which enable routing, loops, and complex logic.
*Hands-on Lab 3: Refactoring an Agent into a LangGraph

*Models: Understanding the difference between LLMs and ChatModels and how to integrate various providers (e.g., OpenAI, Anthropic, open-source models via Ollama).
*Prompts: Mastering PromptTemplates for creating reusable, secure, and effective prompts.
*Output Parsers: A critical component for architects. Learn how to enforce schemas and structure LLM responses into reliable data formats (like JSON or Pydantic models) to ensure clean data contracts within a larger system.
*LCEL (LangChain Expression Language): A deep dive into the | (pipe) syntax for building declarative, streamable, and batch-able data flows.
*Hands-on Lab 1: Building a Production-Ready RAG Pipeline

*The ReAct Framework: Deconstruct the core Reason-Act loop that gives an agent its autonomy.
*Tools: Define an agent's capabilities. We will cover how to create custom tools and, most importantly, how to write effective tool descriptions so the LLM can reason about their use.
*Agent Executor: Understand the runtime that orchestrates the agent's interaction with its tools.
*Observability with LangSmith: Introduce LangSmith as an essential tool for debugging and tracing an agent's "thought process." Discuss why this is non-negotiable for production systems.
*Hands-on Lab 2: Building a Research Assistant Agent

*Whiteboarding Session: Design a holistic, production-grade architecture for an agentic application.
*Key Components & Concerns:
*API Layer & Task Ingestion: How users interact with the system (e.g., FastAPI, message queues like RabbitMQ or Kafka for async jobs). 
*Orchestration Service: The containerized LangGraph/CrewAI runtime. Discuss scaling strategies.
*State Management: The critical choice between in-memory, Redis, or a relational database for managing graph state, especially for long- running agents.
*Secure Tool Execution: A deep dive into security. Discuss sandboxing tool execution using Docker, WebAssembly (WASM), or serverless functions to mitigate risks.
*Evaluation & Monitoring: How do you test and monitor a non-deterministic system? Introduce evaluation frameworks (e.g., RAGAs) and the concept of a "golden dataset" for regression testing.
*Capstone Project: Design & Build
*Final Wrap-up, Future Trends & Q&A
