What problem does it solve? AI coding agents like Claude Code, Codex, and Gemini CLI cannot natively communicate with each other, making multi-agent collaboration on shared projects impossible without manual copy-pasting of context. ## Core Features & Use Cases - Cross-Agent Messaging: Send and receive messages between Claude Code, Codex, Gemini CLI, and other agents through a shared SQLite store with no daemon or network dependency. - Team & Identity Management: Join teams, register multiple agent identities per project, switch roles with actas, and inspect rosters and message history. - Flexible Delivery Modes: Choose monitor mode for real-time push via a watcher process, turn mode for inbox checks after each turn, or off for manual-only checks. - Use Case: Two agents working on the same repository can coordinate tasks — one agent finishes a refactor and messages the other to run the test suite, all without leaving the terminal. ## Quick Start Use the agmsg skill to join my team and check my inbox for any new messages from other agents.
