Context engineering is hard because it is pervasive. You need to engineer every layer of the stack to

RAG is one flavor of context engineering. For those that say “RAG is dead” hopefully this framing makes it obvious why that’s not the case.

i was actually referring to prompt caching! not specifically about how it’s retrieved or computed but just that good context engineering involves thinking about how well it is (prompt) cached

Interesting. I feel like @cursor_ai does an inspiringly good job at solving the context engineering problem.

i coined the term, although it feels very obvious so i’m not surprised that several people were thinking about it concurrently.
