Foremerge
Catch intent conflicts between parallel coding agents
Foremerge is an open-source coordination protocol for coding agents, built on top of Git. Agents keep isolated worktrees but share intent, semantic claims, dependencies and provisional changes, so each one sees what the others are about to change before conflicting work lands.

Overview
Who is it for?
Developers running several coding agents on the same project at once.
Problem
Parallel agents in separate worktrees can each produce correct-looking changes that undo each other when merged.
Solution
A local coordination layer with a deterministic conflict detector that flags intent conflicts early.
What makes it unique
Detects conflicts in intent, not just in lines of code, and installs itself from a one-line prompt to your agent.
Foremerge FAQ
How do I set it up?
Paste one line into Claude Code, Codex or Cursor and the agent installs and wires up Foremerge.
Is it production-ready?
Version 0.5.0 is a pre-1.0, local-first MVP; public schemas may still change and coordination across machines isn't supported.
What's included?
A CLI, JSON API, MCP server, SQLite store and deterministic conflict detector.
