The excessive context leads to token bloat, increased latency, blurred agent responsibilities, and difficult root-cause analysis. The developer recommends task-specific context building and retrieval to improve scalability and maintainability.", "body_md": "Last week I was reviewing the architecture of an AI agent platform designed to automate video generation.\n\nThe concept was solid.\n\nA researcher agent gathered information, planning agents created the structure, writing agents generated content, and downstream agents transformed everything into outputs ready for video production.\n\nOn the surface, it worked remarkably well.\n\nEvery agent produced structured JSON.\n\nThe workflow completed successfully.\n\nThe final output looked convincing.\n\nIf I had only evaluated the demo, I probably would have approved the architecture.\n\nThen I started looking at how the agents communicated with each other.\n\nThat's where the real problems appeared.\n\nInstead of giving each agent only the information it actually needed, almost every agent received nearly the entire execution context.\n\nResearch.\n\nConversation history.\n\nIntermediate outputs.\n\nPrevious reasoning.\n\nGenerated content.\n\nPlanning documents.\n\nEverything.\n\nThe assumption was simple:\n\nMore context means smarter agents.\n\nFor a prototype, that's often true.\n\nFor production, it becomes one of the biggest architectural liabilities.\n\nSmall AI systems hide architectural mistakes.\n\nImagine you have:\n\nGiving every agent the full context feels harmless.\n\nThe model performs well.\n\nDevelopers move faster because they don't need to think about orchestration or state management.\n\nIt creates the illusion that the architecture is scalable.\n\nUnfortunately, it usually isn't.\n\nAs usage grows, the problems multiply.\n\nEvery agent repeatedly receives information that has nothing to do with its current task.\n\nInstead of processing:\n\n```\nResearch Summary\n```\n\nthe agent receives:\n\n```\nResearch\nPlanning\nDraft\nFeedback\nPrevious outputs\nConversation history\nSystem logs\nMetadata\n```\n\nNow imagine that happening across ten or twenty agents.\n\nYour token consumption grows far faster than your user base.\n\nLarge contexts increase latency.\n\nEvery request requires:\n\nOne slow agent delays every downstream agent.\n\nEventually the orchestration pipeline becomes the bottleneck.\n\nLLMs are surprisingly good at extracting useful information.\n\nThey're also surprisingly good at using information they shouldn't.\n\nIf an agent receives unrelated context, there's always a chance it influences the output.\n\nA formatting agent shouldn't make editorial decisions.\n\nA title generator shouldn't rewrite research.\n\nA quality reviewer shouldn't accidentally inherit draft instructions.\n\nGiving agents excessive context blurs their responsibilities.\n\nImagine asking:\n\nWhy did this agent generate this output?\n\nIf every execution contains hundreds of unrelated context objects, finding the answer becomes difficult.\n\nWas it:\n\nWithout clear boundaries, root cause analysis becomes guesswork.\n\nThe problem wasn't only \"too much context.\"\n\nThe architecture had no strong concept of task isolation.\n\nMultiple agents operated on shared execution data without strict ownership.\n\nThat introduces risks such as:\n\nThis isn't always obvious during development.\n\nIt becomes painfully obvious under production load.\n\nOne principle has consistently worked well in distributed systems:\n\nComponents should receive only what they need to perform their responsibility.\n\nAI agents are no different.\n\nInstead of this:\n\n```\nEntire Workflow Context\n        ↓\n Every Agent\n```\n\nThink like this:\n\n```\nTask\n   ↓\nContext Builder\n   ↓\nRelevant Context\n   ↓\nAgent\n   ↓\nStructured Output\n```\n\nThe context builder becomes responsible for assembling exactly what the agent requires—nothing more.\n\nOne thing I missed in this architecture was proper task-level identification.\n\nEvery execution should have unique identifiers such as:\n\nThese IDs make it possible to:\n\nWithout them, large multi-agent systems become difficult to reason about.\n\nInstead of broadcasting the entire execution state to every agent, use retrieval.\n\nWhen an agent starts work, ask:\n\nBuild a task-specific context.\n\nEverything else stays outside the prompt.\n\nThe result is:\n\nMany discussions around AI focus on:\n\nThose things matter.\n\nBut once systems reach production scale, orchestration becomes more important than prompting.\n\nThe quality of an AI platform depends less on how intelligent each agent is and more on how clearly responsibilities are separated.\n\nThe system I reviewed wasn't failing because of the LLM.\n\nIt wasn't failing because of the prompts.\n\nIt wasn't failing because of structured outputs.\n\nIts biggest weakness was architectural.\n\nAs an industry, we're spending enormous effort making agents smarter.\n\nWe should spend just as much effort making them smaller, more focused, and better isolated.\n\nIn distributed software, good architecture comes from clear boundaries.\n\nThe same principle applies to multi-agent AI systems.\n\nAs these systems move from demos to enterprise production, context management will become one of the defining factors separating reliable platforms from impressive prototypes.", "url":
