context-engineering vs Matryoshka

context-engineering: Context engineering is the practice of providing LLMs with comprehensive context from various sources. It emphasizes that quality and completeness of context matter more than prompt wording. This repository is a companion resource for a book on context engineering, containing examples and an online prompt builder.; Matryoshka: Matryoshka (RLM) addresses the limitation of fixed LLM context windows by using a recursive language model approach. Instead of chunking or RAG, the LLM outputs commands in a constrained symbolic language called Nucleus, which are executed by the Lattice logic engine. This reduces entropy, enables safe execution, and achieves 97% token savings through handle-based storage.
