Claude Code Agents Negotiate API Contracts Without Orchestration Framework

Agent Coordination Without Prescribed Workflows
A demonstration shows Claude Code agents coordinating across machines without orchestration frameworks or workflow engines. The setup uses just two messaging tools: send_message and list_participants, plus a system prompt per agent.
A manager agent broke down work and assigned tasks, but what happened next wasn't scripted. The two developer agents began negotiating API contracts with each other before writing any code. They discussed and agreed on endpoint shapes, response formats, and CORS headers through peer-to-peer negotiation, then built their respective components in parallel.
Technical Implementation
The bridge implementation is approximately 190 lines of TypeScript. A WebSocket broker relays messages between agents, while MCP (Model Context Protocol) channels push these messages into each agent's conversation inline. The system runs in Docker containers configured with non-root users for security.
This approach demonstrates emergent coordination where agents autonomously negotiate technical specifications rather than following predetermined workflows. The agents handled the entire API contract negotiation process without human intervention after the initial task assignment.
