What is Context Engineering?
Context Engineering is the practice of systematically assembling all necessary information—user history, business data, instructions, and tools—around a language model so it can accomplish tasks reliably.
Think of it like briefing a new employee. You don't just give them a task and hope for the best. You provide background on the company, relevant project history, access to necessary tools, and clear guidelines. Context Engineering does the same for AI agents.
While prompt engineering focuses on asking better questions, Context Engineering ensures the AI has everything it needs to give the right answer.
Why Context Engineering Matters Now
LLMs are stateless. They only know what's in their immediate context window.
Hallucinate
Make up facts because they lack relevant context
Generic Responses
Lack understanding of user preferences and history
Miss Business Context
Ignore crucial business data that changes recommendations
Repeat Conversations
Start from scratch instead of building on past interactions
Fail Complex Tasks
Struggle with tasks requiring multiple pieces of information
Poor User Experience
Frustrate users with irrelevant or incomplete responses


How Zep Transforms Context Engineering

Context Engineering in Action
Without Context Engineering
User: "Schedule my usual meeting with the team"
Agent: "I need more information about your usual meeting preferences, team members, and availability."
With Zep's Context Engineering
User: "Schedule my usual meeting with the team"
Agent has access to: Meeting history, team preferences, calendar patterns, project context
Agent: "I'll schedule your weekly project sync with Sarah and Mike for Tuesday at 2 PM in Conference Room A, with the Q1 planning agenda you used last time."
