Weaviate AI Database on X: "A bigger context window won't fix a broken agentic RAG pipeline. Long contexts can introduce contradictory information, bury relevant tools, and cause later inputs to be ignored. Every retrieved chunk, tool output, instruction, and conversation turn competes for the model's attention. This is why production agentic RAG is really a 𝗰𝗼𝗻𝘁𝗲𝘅𝘁 𝗲𝗻𝗴𝗶𝗻𝗲𝗲𝗿𝗶𝗻𝗴 problem: controlling what information reaches the model, when, and in what form. In our newest Youtube video, @victorialslocum breaks down the five systems that make up an agentic RAG pipeline: 1️⃣ 𝗤𝘂𝗲𝗿𝘆 𝗔𝘂𝗴𝗺𝗲𝗻𝘁𝗮𝘁𝗶𝗼𝗻 - translating vague, misspelled, or multipart human input into something retrieval and downstream tools can actually use 2️⃣ 𝗥𝗲𝘁𝗿𝗶𝗲𝘃𝗮𝗹 - choosing a chunking strategy that balances precision with enough surrounding context. Small chunks can lose meaning; large chunks consume context and produce noisier embeddings. 3️⃣ 𝗠𝗲𝗺𝗼𝗿𝘆 - separating active short-term context from externally stored long-term memory. Dumping the full conversation history into every request just lets stale details compete with current information. 4️⃣ 𝗧𝗼𝗼𝗹𝘀 - giving the model clear descriptions, schemas, and access to the right tools at the right stage. Many tool failures are actually context engineering failures in disguise. 5️⃣ 𝗔𝗴𝗲𝗻𝘁𝘀 - the decision and orchestration layer connecting everything above. Agents can reformulate queries, select tools, evaluate results, and change strategy, but they also compound every upstream context failure. A better prompt can't repair irrelevant retrieval, contradictory memory, or a tool the model can't find. The video: https://t.co/M9I9WKbOjL" / X
