Meta Graduates Muse Code Out of Beta With Inter-Session Messaging, Workflow Orchestration and TypeScript SDK

Meta pulled its Muse Code terminal agent out of beta Aug 31, adding inter-session messaging over Unix sockets, workflow orchestration for multi-subagent tasks, and a double-Esc rewind. A TypeScript SDK in developer preview lets programs spawn a local 'muse' host over the new Muse Session Protocol with no network layer. Three monthly subscription tiers replace pure pay-as-you-go, undercutting Anthropic and OpenAI's coding-agent pricing.
