Module 16 · Chapter 14: Context engineering
Context engineering: what the agent reads
In short
An agent starts every session from zero. Give it a one-page instruction file with no secrets, load only what the task needs, and write progress in a ledger each time a step finishes so a new session can continue.
After this lesson you can
- Write a project instruction file the agent reads every session
- Choose what material goes into the context and what stays out
- Keep progress on long work in a ledger outside the session
