Foremerge is the open-source coordination protocol for coding agents, built above Git. Agents keep isolated worktrees while sharing intent, semantic claims, dependencies, provisional ChangeSets, decisions, validation, and provenance. Tell your agent to install → Done → See collisions before they land Paste one line into Claude Code, Codex, or Cursor It installs Foremerge and wires itself up Every agent sees what the others are about to change, even in separate worktrees Status: Foremerge 0.5.0 is a pre-1.0, local-first MVP. The CLI, JSON API, MCP server, SQLite store, deterministic conflict detector, and verification-gated lifecycle are implemented. Public schemas may still change. Published benchmark results do not yet exist, and coordination between machines is outside this project's scope. How it works Say you have two AI agents working on the same project at the same time. Each one gets its own copy of the code, so they never fight over files. Both finish. Both look correct.…
