Hoard things you know how to do
Agentic Engineering Patterns > Many of my tips for working productively with coding agents are extensions of advice I've found useful in my career without them.

Quoting Andrej Karpathy
It is hard to communicate how much programming has changed due to AI in the last 2 months: not gradually and over time in the "progress as usual" way, but specifically this last December. There are a number of asterisks but imo coding agents basically didn’t work before December and basically work since…
