Not exactly just RAG. The shift is agentic discovery paired with semantic search.

Also, most of the coding agents still combine RAG and agentic search. See cursor blog about how semantic search helps them understand and navigate massive codebases: https://cursor.com/blog/semsearch

The pendulum swings back.

This is happening over and over and over. The example of prompt engineering is just a form of protocol. Context engineering is just about cache management. People think LLMs will replace programming languages and runtimes entirely, but so far it seems they have been used mostly to write programs in programming languages, and I've found they're very bad interpreters and compilers. So far, I can't really pick out what exactly LLMs are replacing except the need to press the individual keys on the keyboard, so I still struggle to see them as more than super fancy autocomplete. When the hype is peeled away, we're still left with all the same engineering problems but now we have added "Sometimes the tool hallucinates and gaslights you".
