Agent-to-agent communication across distributed systems is enabled by discovering remote capabilities via AgentCard and invoking remote skills as local tools. This allows distributed agents to collaborate seamlessly across network boundaries without direct host-level coupling.

AgentCard discovery is the process of exposing and identifying skilled capabilities across distributed agents. It works by allowing a central orchestrator to find remote agent services and invoke their specific skills as tooling wrappers for cross-agent workflows.

Yes, you can invoke remote skills as local tools in a multi-agent system using tooling wrappers like A2ASkillTool and A2ASkillToolFactory. These components wrap remote capabilities so a central orchestrator can execute them seamlessly alongside internal functions.

To set up a distributed agent system with cross-host collaboration, register and expose an agent as an A2A service first. Then, use a central orchestrator to discover AgentCards and invoke the exposed remote skills to build orchestrated workflows.

Yes, agent-to-agent communication requires structured schemas for remote skill invocation. The A2A client and server interfaces rely on these structured schemas to ensure reliable capability exposure and accurate cross-agent orchestration across network boundaries.

The best way to build cross-agent workflows without tight host coupling is using A2A client and server interfaces. This approach abstracts remote skill invocation into tooling wrappers, enabling agents to collaborate through structured AgentCard discovery rather than direct integration.
