Day 7/30: Harness Engineering 🔧 The model is the brain. The harness is everything else. Agent = Model + Harness. Most people obsess over which AI model to use. The builders winning right now? They’re obsessing over the harness — the system that makes model intelligence actually useful. Here’s what a harness includes: 🗂 Filesystem — durable memory across sessions ⚙️ Sandbox — safe code execution environment 🧠 Memory + Search — learning beyond the knowledge cutoff 🛡 Context Management — protecting performance over long tasks Same model. Better harness. One team jumped from Top 30 to Top 5 on a coding benchmark without touching the model once. That’s not a coincidence. That’s harness engineering. If you’re building AI agents — this is the skill that separates demos from production. #AgenticAI #AIAgents #HarnessEngineering #LLMs #AIEngineering MachineLearning AIBuilder FutureOfWork ArtificialIntelligence AITools
