  Mind Map Your App Before You Write a Line of Code

  What production AI agents actually require

  Most "AI agents" shipping right now are demos wearing production paint. They answer questions fluently and break the moment they touch a workflow with money, state, or consequences.

  How to Keep Your Developer Instincts When AI Writes the Code

  The promise was less friction. The cost, it turns out, is instinct, a high price to pay. The answer: add deliberate practice to your routine, and keep the struggle.
