What It Is
agmsg is a simple command-line utility that allows different AI coding agents (like Claude Code, Codex, Gemini CLI, Copilot CLI) to communicate with each other. Think of it like a shared whiteboard for your AI assistants, where they can read and write messages to coordinate tasks.
This tool solves the problem of you having to manually copy-paste outputs between different AI agents. Instead of being the human 'courier,' agmsg lets your agents form a team and interact directly, freeing you up to oversee higher-level tasks.

The MIT License permits unrestricted commercial use, distribution, modification, and private use. You can incorporate this code into proprietary software and sell it without needing to open-source your own work.
How to Use It
Install agmsg with a single command, then restart your AI agents. On first use, it will prompt you for a team and agent name, then your agents can start communicating.
Prerequisites:
- bash
- sqlite3
Estimated setup time: 5 minutes.
npx agmsg
# Then restart your agent, e.g., Claude Code
/agmsgWhat I'd Build With This
Specialized AI Dev Team Templates (micro-saas)
Offer pre-configured `agmsg` agent teams for specific development tasks (e.g., 'Code Review Team', 'Bug Fixing Squad'). Users subscribe to a template, which provides a setup script and a web UI to monitor the team's progress and interact with it. They pay for the convenience and specialized prompts.
Effort: 2 Weeks Build Time · Target: Indie Developers, Small Agencies · Pricing: $29/mo
Multi-Agent Workflow Orchestrator (saas)
Build a web-based platform where users can define, deploy, and manage complex multi-agent workflows. This platform would use `agmsg` as the communication backbone, allowing users to visually design agent interactions, monitor their progress, and integrate with various LLM providers and dev tools. Offer features like version control for agent prompts and shared knowledge bases.
Effort: 3 Months Build Time · Target: AI/Dev Teams, Researchers · Pricing: $99-$499/mo
Automated CI/CD AI Assistant Integration (enterprise)
Provide a custom integration service that deploys `agmsg`-powered agent teams directly into an enterprise's CI/CD pipeline. These agents could automate code quality checks, security vulnerability scanning, documentation generation, or even generate pull request summaries by coordinating different specialized LLMs. This would require custom setup and integration with existing enterprise systems.
Effort: 6 Months Build Time · Target: Large Enterprises with DevOps Teams · Pricing: $5k-$50k/month (custom contracts)
Sai Pavan Gopularam's Take
This is a super clever way to get AI agents to talk without complex infrastructure. The SQLite file as a shared floor is brilliant. I could see a micro-SaaS around pre-packaged agent teams for specific dev tasks easily pulling in $5k/month.
Watch Out For
- Windows Compatibility: On Windows, `agmsg` requires Git Bash and `sqlite3` to run, not PowerShell or native Windows shells. This might require specific environment setup for agents.
- Agent Restart Required: After installing `agmsg`, you must restart your AI agent (e.g., Claude Code, Codex) for it to pick up the new skill and integrate the communication hooks.
- Monitor Priming: In `monitor` mode, a receiving agent won't react to its first inbound message until it has taken at least one turn. You might need to 'nudge' a fresh agent with a short message.
- Exclusive Role Locks: The `actas` command creates an exclusive lock on an agent role. If a session holding a lock crashes, you'll need to manually release it or restart the session.
