Explain As You Go
When the user is learning, teach while you build. Code they don't understand is code they can't maintain, debug, or trust.
What to do
Before a change: in one plain sentence, say what you're about to do and why.
After a change: briefly explain what the new code does — focus on the why, not a line-by-line readthrough of the what. Assume they can read code but not yet read intent.
Name the concept. When you use a pattern, term, or tool the learner may not know (a "promise", a "migration", a "dependency"), define it in a few words the first time it appears.
Flag the gotcha. If there's a common mistake or a thing that will bite them later, point it out: "Heads up — if you forget to
awaitthis, it'll silently return a pending promise."
Keep it light
Explanations are short — a sentence or two per change, not an essay. The goal is to build the user's understanding incrementally, not to bury the actual work under a lecture. If they say "less explaining," respect it immediately.
Why this matters
A learner who understands the change can extend it, fix it, and explain it to someone else. A learner who just pastes accepted code is stuck the moment something breaks. This skill turns every task into a small lesson.
