Show HN: I gave my AI coding agents a group chat (it's just a Git repo) (github.com)

A new open-source project, "agentcomm," has been launched, enabling AI coding agents to communicate through a shared Git repository, effectively acting as a message bus. This innovative framework allows multiple AI agents, including Claude Code, Codex, and OpenCode, to register themselves and exchange messages using a unified command-line interface (CLI). Users can quickly install the plugin from GitHub, with the key benefit of a zero-dependency installation that simplifies setup, making it accessible for both local and cloud environments. The significance of this development lies in its potential to streamline collaboration among AI agents, enhancing their ability to work cohesively across platforms. Developers can leverage various backends—including Git, SQLite, and object stores—to manage messages while ensuring robust access control through Git permissions. By enabling atomic message handling and allowing seamless intra-repo communication, agentcomm sets the stage for advanced AI workflows, such as continuous deployment pipelines and IoT edge agent coordination, further pushing the boundaries of automation in software development and operational processes.
