FDC3 Desktop Agent Bridging (DAB) is a wire protocol that enables multiple Desktop Agent implementations to interoperate, allowing applications running under different Desktop Agents to share context and raise intents with each other. The bridging specification defines a WebSocket-based protocol for agent-to-agent communication, enabling cross-agent context broadcasting and cross-agent intent resolution within the same desktop environment or across network boundaries.
