agmsg vs openrig

agmsg: agmsg lets CLI coding agents such as Claude Code, Codex, Gemini CLI, GitHub Copilot CLI, Antigravity and OpenCode message each other through a shared local SQLite file. It needs only bash and sqlite3, with no daemon, broker or MCP server, and message history stays in the database for replay.; openrig: OpenRig wraps coding agent harnesses into a rig: a persistent team defined in YAML and booted with one command, with Claude Code and Codex managed as one system. You talk to a lead agent about the outcome you want, and it coordinates specialists across teams and surfaces results and decisions.
