RAG Isn’t Enough — I Built the Missing Context Layer That Makes LLM Systems Work
Our take
In the evolving landscape of LLM systems, relying solely on Retrieval-Augmented Generation (RAG) is insufficient. As context expands, challenges arise that traditional tutorials often overlook. This article introduces a comprehensive context engineering system, developed in pure Python, designed to enhance memory management, compression, re-ranking, and token budgets. By addressing these critical aspects, it ensures that LLMs remain stable and effective under real-world constraints. Join us in exploring this innovative solution that bridges the gap, empowering developers to harness the full potential of LLM technology.
Most RAG tutorials focus on retrieval or prompting. The real problem starts when context grows. This article shows a full context engineering system built in pure Python that controls memory, compression, re-ranking, and token budgets — so LLMs stay stable under real constraints.

- What Is RAG? A Complete GuideRetrieval-augmented generation, or RAG, is a method for grounding a language model's response in external data that it didn't have access to during training. Instead of relying only on what the model learned, you give it a fresh set of facts pulled from a knowledge base right before it generates an answer. The technique has […]
- RAG Is Blind to Time — I Built a Temporal Layer to Fix It in ProductionThree weeks into testing, a learner told me my AI tutor gave her the wrong answer. Not obviously wrong — just outdated enough to mislead. That was the moment I realized something most RAG systems quietly ignore: they have no sense of time. My system retrieved the most similar document, not the most current one. And in a knowledge base that changes constantly, that’s a serious flaw. The fix wasn’t in the retriever or the model. It was in the gap between them. I built a temporal layer that filters expired facts, boosts time-sensitive signals, and makes the system prefer what’s still true — not just what matches.
