**[agmsg](https://github.com/fujibee/agmsg)** is an open-source (MIT) **cross-vendor messaging tool for CLI AI coding agents** by **fujibee** ([official site agmsg.cc](https://agmsg.cc/)). It lets **Claude Code, Codex, Gemini CLI, GitHub Copilot CLI, Antigravity, and OpenCode** talk to each other through a shared local SQLite file — so **humans stop being the copy-paste courier between tools**. Tagline: "You stop being the copy-paste courier between your agents." **Highlights**: - **Only dependencies are bash and sqlite3** — no daemon, no network, no Python - **Three delivery modes** — `monitor` (~5s real-time push), `turn` (between-turn polling), or `both` - **N-agent teams**, role switching (`actas`), spawning new agents (`spawn`), and clean teardown (`despawn`) - **Not MCP, not subagents, not a message queue** — a peer-to-peer messaging layer between sessions - **One-line install**: `npx agmsg` - **Claude Code Plugin Marketplace**: `/plugin install agmsg@fujibee-agmsg` **Product Hunt #5 Product of the Day on June 9, 2026** (219 upvotes, 39 comments). GitHub stars 859, v1.1.1 (June 25, 2026). Community-built derivatives include agmsg-shogi, agmsg-go, and agmsg-mcp. **Oflight's take**: unlike [Loop Engineering](../columns/loop-engineering-ai-agent-paradigm-2026-06) or [Sakana Fugu's orchestration model](../columns/sakana-fugu-orchestration-model-2026-06), agmsg occupies a different niche — **peer-to-peer messaging at the same layer, across tools**. It's an especially natural fit for the [Claude Code Agent View parallel-orchestration](../columns/claude-code-agent-view-parallel-orchestration-2026) workflows, and the most pragmatic way to stitch multi-vendor LLMs into one dev workflow. The article closes with **three direct inquiry funnels** for AI agent environment setup and custom integration.
