The authors start by reminding that a language model chooses each next token based on past tokens plus the surrounding context. 

Older prompt-engineering ideas package that context as one long prompt string, which works for toy demos but quickly falls apart in real systems.

They then reject the single-string view and introduce context engineering. 

Here, the context is a bundle of smaller parts that get sourced, filtered, and glued together by helper functions before each model call. 

Treating context as several moving pieces makes it easier to swap data in and out on the fly.
