Context Engineering explained in 5 minutes by Jess Weng.

@jess_weng18 good one; I was just watching the deep agents course on the langchain academy :))

@jess_weng18 context engineering feels like the skill that quietly decides whether an agent works or just rambles. five minutes is a good length for explaining it

@jess_weng18 saw this in my own tests this week. same prompt, max effort ended around 800k tokens of context, medium around 300k, and i liked the medium result more. more context isn't automatically better

@jess_weng18 context engineering is like 80% deciding what to leave out
