Advisory Claim System Aims to Stop AI Coding Agents from Overwriting Each Other

When multiple developers run AI coding agents simultaneously, two agents can edit the same file at the same time, causing work to be overwritten or creating complex merge conflicts. Traditional tools like Git branch protection and CI pipelines only detect these collisions after the fact, making them insufficient for preventing the problem at its source. The proposed solution is a shared intent-coordination layer where an agent declares a claim on a file path before editing, and other agents check that registry first to avoid overlap. A tool called Vibsync implements this approach via an MCP-compatible interface, allowing agents to check and claim file paths before making any changes. The system is designed to complement Git rather than replace it, with Git remaining the authoritative safety net while claims reduce preventable conflicts upstream.
