A team of developers, each running their own AI coding agent, is fast — right up until two agents refactor the same file at the same time. One overwrites the other's work, or you discover the collision at merge time and spend the afternoon untangling it.
You can't always prevent this with Git alone: by the time there's a conflicting commit, both agents have already done the work. The goal is to coordinate intent — before the edits happen.
Why this is different from a merge conflict
A merge conflict is detected after both sides changed the code. What you actually want is to know, before you start, that a teammate's agent is already rewriting the module you're about to touch. That's an intent problem, not a diff problem, so branch protection and CI don't solve it — they run too late.
