Leveraging A2A Protocol for Enhanced Agent Orchestration: A Comparative Analysis

[sing1ee]

For Claude Code, subagents represent a critical architectural component. Their implementation relies on custom system prompts combined with isolated execution environments, while fundamentally remaining instances of Claude Code itself. Additionally, Claude Code provides native support for MCP (Model Context Protocol).

In contrast, Gemini CLI also offers MCP compatibility but requires a more robust agent orchestration mechanism to handle both local and remote agent deployments effectively. This is where the A2A (Agent2Agent) protocol presents a superior solution.

The A2A Advantage for Gemini CLI:

The A2A protocol enables Gemini CLI to function as a sophisticated orchestration layer, capable of:

• Planning and coordinating distributed agent workflows
• Managing both local and remote A2A agents seamlessly
• Providing a unified interface for complex multi-agent scenarios

This approach positions A2A protocol as the optimal choice for building scalable, distributed agent ecosystems, particularly when leveraging Gemini CLI's planning and orchestration capabilities.

@sing1ee there is a PR for this: google-gemini/gemini-cli#3079

Although I am not quite sure what you are suggesting to discuss in this discussion :)
