Stop copy-pasting between your AI coding agents
agmsg is a lightweight, vendor-agnostic messaging tool designed to facilitate seamless communication between multiple AI coding agents such as Claude Code, Codex, Gemini CLI, and Copilot CLI. Unlike traditional methods that rely on copy-pasting or ephemeral subagents, agmsg uses a shared SQLite database to enable persistent, direct messaging without the need for daemons, network configurations, or Python scripting. Its minimalist approach leverages simple bash and sqlite3 commands, making it accessible and easy to deploy as an Agent Skill. This unique setup allows developers to run several AI agents—potentially multiple instances of Claude Code—working together within a single environment, fostering collaborative and efficient AI-driven coding workflows. Its open-source nature and vendor-neutral design make it appealing for developers seeking flexible, persistent multi-agent interactions without vendor lock-in or complex infrastructure.
Pros
- Vendor-agnostic and supports multiple AI agents simultaneously
- No need for daemons, network setup, or complex Python scripts
- Persistent messaging through shared SQLite database
- Lightweight and easy to install using bash and sqlite3
- Enables collaborative multi-agent AI coding environments
Cons
- Requires familiarity with bash and SQLite for setup and operation
- Limited to command-line interface, possibly less user-friendly for non-technical users
- Potential scalability issues with very large message volumes or multiple concurrent agents
Best for
- • Facilitating real-time multi-agent AI coding collaborations
- • Creating persistent communication channels between different AI models
- • Automating multi-step AI workflows without external dependencies
- • Experimenting with multi-agent AI interactions in development environments
Pricing: Likely open source and free to use, as agmsg is designed as a lightweight, minimal dependency tool relying on bash and sqlite3. There may be optional paid support or hosting if extended features are added, but primarily it appears to be free.
