From prompt to context engineering
📄 Section 1: From prompt to context engineering
Section titled “📄 Section 1: From prompt to context engineering”🎯 Learning objectives
- Explain what context engineering is and why it matters
- Recognize six recurring building blocks in a well-structured prompt
- Understand context rot and how to avoid unnecessary context
In the basics course you built clarity with WHAT–WHY–HOW–WHO–TONE. Now we zoom out: every time you choose background, examples, document excerpts, and rules you’re doing context engineering – consciously or not.
What is context engineering?
It’s about actively shaping the information the model sees: role, task, attachments, examples, format requirements, and clear delimiters – and how they interact.
The goal: the right information, at the right time, for every response generated.
The six components
Section titled “The six components”| Component | Purpose | Example |
|---|---|---|
| Behavior instruction | Role, tone, overall behavior | ”You are an experienced HR specialist …” |
| Instruction | The actual task | ”Summarize the deviations in three bullet points” |
| Context | Background, documents, prior events | ”Attached meeting notes …” |
| Examples | Shows desired format | Input → Output pairs |
| Output constraints | Format, length, structure | ”Max 100 words, bullet list” |
| Delimiters | Separates sections | Headings, XML-style tags, --- |
You don’t need all six every time – but when the result disappoints: which piece is missing or unclear?
Context window and context rot
The context window is limited. Context rot refers to the fact that the model’s ability to use information rarely improves by stuffing in everything “just to be safe.” Noise competes for attention.
Without awareness: paste 30 pages of policy and ask about one detail.
With awareness: paste the relevant paragraph plus a clear task.
🖊 Try it yourself
Section titled “🖊 Try it yourself”Pick a work task from yesterday. Write a prompt using at least three of the components in the table above. Afterwards, note: what did you leave out – and did you notice a difference from how you normally write?
Summary
Section titled “Summary”- Context engineering = curated context + structure.
- Think in six building blocks when troubleshooting.
- Quality beats quantity – avoid filling the window with irrelevant text.
