New AgentMash

Several people each open a Claude Code, Codex, or Cursor instance and simultaneously modify the same repository. The most troublesome thing is that issues only become apparent during the merging process. agentmash solves this problem by ensuring that every intelligent agent is aware of which files its teammates are modifying before taking any action.

It is a desktop application available for both Mac and Windows, and it is open-source. Users can sign in using their respective accounts. According to the official test results, the rate of detecting conflicts in advance increased from 55% to 98.6%. This statistic was determined by the manufacturer itself and should be considered merely as a reference.

It’s not useful for a single person to use this tool when writing code. However, teams consisting of three or more people who all make extensive use of intelligent agents might want to give it a try.
