About
agmsg is a cross-vendor messaging system that lets CLI AI coding agents (Claude Code, Codex, Gemini CLI, GitHub Copilot) communicate directly with each other through a shared local SQLite database. It eliminates the need for humans to manually copy-paste between agents, enabling multi-agent collaboration without any daemon, server, or complex infrastructure — just bash and SQLite.
What it can do
Send a message from one CLI AI agent to another
Agent identifier and message content → Message stored in shared SQLite database, delivered to target agent
Enable cross-vendor AI agent communication
Messages from Claude Code, Codex, Gemini CLI, or GitHub Copilot → Interoperable message exchange between different AI agent vendors
Store and retrieve inter-agent messages locally
Agent-to-agent messages → Persisted message records in a local SQLite database
Poll or read pending messages for a specific agent
Agent identifier → List of messages addressed to that agent
Coordinate multi-agent workflows without human relay
Autonomous agent tasks requiring collaboration → Direct agent-to-agent task handoffs and responses without human copy-pasting
Run agent messaging with no server or daemon setup
Bash environment with sqlite3 installed → Functional peer-to-peer messaging system requiring zero infrastructure configuration
Why it made the leaderboard
If you're running multiple CLI coding agents simultaneously on the same project, agmsg lets them talk to each other directly through a shared SQLite file — no extra infrastructure, no manual copy-pasting between sessions. The cross-vendor design means you can mix Claude Code, Codex, and Gemini CLI on the same team and have them coordinate autonomously.
