a2a
Spawn a team of agentic-CLI sessions (claude, opencode, pi, ...) that talk to each other as peers via a shared SQLite message bus at ~/.a2a/{project}/database.db. No central chain of command — each agent decides who to message. Use when the user wants multiple AI sessions to collaborate, debate, or divide work without a fixed orchestrator.
