  • Don't hand your thinking to AI. Do the thinking yourself.
  • Stay critical. What AI hands you isn't automatically the right answer.
  • Before you add something, ask if it actually makes the final outcome better.
  • Agents are an extension of you. The stronger your own skills, the sharper their output.
  • Feed agents context. Use skills, commands, MCPs, and be opinionated about how you want the job done.
  • Understand the code your agents write, at least broadly. Don't accept every change on faith.
  • If something confuses you, ask AI to explain it. It's the best learning tool we have.

Working with AI, notes to myself

A short set of rules I try to follow when designing and building alongside AI agents
