Foremerge is an open-source coordination protocol for coding agents built above Git. Agents keep isolated worktrees while sharing intent, semantic claims, ChangeSets, and verification. It solves the problem in which Git, which compares text rather than intent, fails to detect conflicts when multiple agents work on the same project. Even when changes do not overlap textually, agents can undo each other's work—such as one agent removing an extension point the other depends on—without Git raising an alarm.
