Reduce, don't just resolve

Merge small and often, so drift never grows large

You can resolve a conflict. But honestly, doing it every time one pops up gets tiring.

When one happens, don't decide from the code alone; ask

A conflict means two people edited the same spot differently, and the code alone won't say which is right. Before deleting one side, ask the author "what were you going for?" That's fastest and safest.

The longer a branch lives, the bigger the clash

While you work, others keep moving main forward. The longer your branch stays away from main, the bigger the conflict when you return. Time spent unmerged is the real risk.

So slice tasks small and merge back often

Don't carry a branch for days. Build small, merge small, and pull main in often (git pull origin main). That's also why GitHub Flow deletes each branch once it is merged: branches are meant to be short.

Resolution skills matter, but the people who are good at this mostly move in a way that keeps conflicts from happening at all.
