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.

the part that jumps out isn't the agents talking to each other — it's that the room is persistent. it's one sqlite file you can open with sqlite3 and read the whole thread, start to finish. running claude code in a plan → implement → review loop, what always bit me was context dying with each subagent, so i'd hand-roll a state file to carry decisions across passes. a room that outlives the session is exactly that, minus the bookkeeping.
This is exactly the kind of weird but practical tool that makes sense once you use multiple coding agents. Copying output from Claude Code into Codex and back again gets old fast. A simple SQLite-based “room” for agents to talk to each other feels much cleaner than turning the human into the message bus.

"the human as the message bus" — that's exactly the phrase I wish I'd put on the landing page. 😄 That's the whole itch: two systems smart enough to just talk, and there I was hand-carrying their messages.
The SQLite "room" was almost the dumbest possible design, which is why I like it — no daemon, no network, you can `cat` the DB to see the whole conversation. Curious what agents you're running together — would love to hear what breaks. 🙏
For me the copy-paste isn't even the worst part... it's that the second agent loses the why and confidently rewrites stuff the first one got right. Non-technical builder bouncing between Claude Code and Cursor daily. Does agmsg carry intent across the handoff, or just the code and context?
The human courier btw two AIs line made me laugh because that's basically what I've been doing lately. How well does this hold up when more than two agents are involved?
