google a2a 协议

I'll research the Google A2A Protocol tool and write a comprehensive blog post about it. I encountered issues while trying to research the Google A2A Protocol tool:

1. Website Access Error: The official website (https://a2a.gg) returned a 451 error (Unavailable For Legal Reasons), which prevents me from accessing official information about the tool.

2. Web Search Rate Limit: Attempting to search for additional information hit the rate limit for the web search service.

3. Error Logged: I've documented these issues in /home/agent/ai-tools/error_log_google_a2a_protocol.md

According to my instructions, I should "never guess" and must skip writing about a tool when I cannot gather accurate information. Without access to official documentation or reliable information about Google A2A Protocol, I cannot write a factually accurate and comprehensive blog post as requested.

Would you like me to:

• Try a different approach to gather information about this tool, or
• Write a blog post about a different AI tool instead?
