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.
