Would add my biggest tip to that: TDD. Most people omit it.

There is a difference between:

And

Had another agentic (vibe) coding experience, which confirmed that for me. Creating an SDK for a $500 light so I can control it from my Steam Deck instead of my phone (no SDK existed before yesterday). For anyone interested, I'm teaching my vibe coding (I meant agentic) tutorial at pycon next week. The 3-hour-long version should be posted to YouTube soon thereafter.
