agmsg
Stop copy-pasting between your AI coding agents
Stop being the copy-paste relay between your AI coding agents. agmsg lets Claude Code, Codex, Gemini CLI, and Copilot CLI message each other directly through a shared SQLite database — no daemon, no network, no Python. Just bash + sqlite3, installed as an Agent Skill. Unlike built-in subagents (single-vendor, ephemeral) or MCP (an agent calling tools), agmsg is vendor-agnostic and persistent. Run several agents — even multiple Claude Code instances — in one room, working together.
agmsg is a Open Source company. It launched on Product Hunt on Jun 9, 2026, with 240 upvotes. Adamlead has 1 person on file at agmsg.
