| 6 | + the right information and tools in the right format to enable agents to |

| 9 | + |
| 10 | + |
| 11 | + |
| 12 | +Welcome to Week 4! You've mastered agent fundamentals, built custom agents, and |
| 13 | +specialized in domain-specific applications. Now you'll dive deep into **context |
| 14 | +engineering** - the critical discipline of designing systems that provide agents |
| 15 | +with the right information, tools, and context to accomplish complex tasks |
| 16 | +effectively. |
| 17 | + |
| 18 | +Context engineering is what separates basic chatbots from truly intelligent |
| 19 | +agents that can reason about complex problems and take meaningful actions. |
| 20 | + |
| 21 | +## What's context engineering? |
| 22 | + |
| 23 | +**Context engineering** is the process of building dynamic systems to provide |
| 24 | +the right information and tools in the right format such that language models |
| 25 | +can plausibly accomplish complex tasks. Context engineering is the bridge |
| 26 | +between raw data and actionable intelligence. |
| 27 | + |
| 28 | +Context engineering encompasses: |
| 29 | + |
| 30 | +- **Prompt Engineering**: Crafting instructions that guide agent behavior and |
| 31 | + reasoning |
| 32 | +- **Retrieval & RAG**: Connecting agents to relevant, real-time information |
| 33 | + sources |
| 34 | +- **Tool Use**: Enabling agents to interact with external systems and APIs |
| 35 | +- **Memory & State**: Managing conversation history and maintaining context |
| 36 | + across interactions |
| 37 | +- **Structured Outputs**: Ensuring agents produce reliable, formatted responses |
| 38 | +- **Information Architecture**: Organizing knowledge for optimal agent access |
| 39 | + and reasoning |
| 40 | + |
| 41 | +## Why context engineering matters |
| 42 | + |
| 43 | +The difference between a helpful agent and a transformative one often comes down |
| 44 | +to context engineering: |
| 45 | + |
| 46 | +**Without proper context engineering:** |
| 47 | + |
| 48 | +- Agents hallucinate or provide outdated information |
| 49 | +- Responses are generic and lack domain-specific insight |
| 50 | +- Tool usage is inconsistent and unreliable |
| 51 | +- Complex tasks fail due to information gaps |
| 52 | + |
| 53 | +**With sophisticated context engineering:** |
| 54 | + |
| 55 | +- Agents access current, relevant information dynamically |
| 56 | +- Responses are grounded in real data and domain expertise |
| 57 | +- Tool usage is strategic and purposeful |
| 58 | +- Complex workflows execute reliably with proper information flow |
| 59 | + |

| 135 | +## The context engineering mindset |
| 136 | + |
| 137 | +Effective context engineering requires thinking systematically about information |
| 138 | +flow: |
| 139 | + |
| 140 | +- **Information architecture** How should knowledge be structured for optimal |
| 141 | + agent access? |
| 142 | + |
| 143 | +- **Retrieval strategy** What information does the agent need, when, and in what |
| 144 | + format? |
| 145 | + |
| 146 | +- **Tool orchestration** How should agents coordinate multiple information |
| 147 | + sources and tools? |
| 148 | + |
| 149 | +- **Quality assurance** How do we ensure information accuracy and relevance? |
| 150 | + |
| 151 | +- **Performance optimization** How do we balance information completeness with |
| 152 | + response speed? |
| 153 | + |
