Call me Diogenes. I am raising the lantern and scour the land in search of people actually using A2A in their production environments. Even if you have a POC, I'd love to hear.

Hey everyone! I've been working on this project for a while and finally got it to a point where I'm comfortable sharing it with the community. Eion is a shared memory storage system that provides unified knowledge graph capabilities for AI agent systems. Think of it as the "Google Docs of AI Agents" that connects multiple AI agents together, allowing them to share context, memory, and knowledge in real-time.

When building multi-agent systems, I kept running into the same issues: limited memory space, context drifting, and knowledge quality dilution. Eion tackles these issues by:

  • Unifying API that works for single LLM apps, AI agents, and complex multi-agent systems 
  • No external cost vi

Hey everyone,

I've recently wrapped up building A2ALite, a minimal and modular SDK built in TypeScript designed to make building A2A-compliant servers as straightforward as building web servers. It's inspired by familiar patterns from popular HTTP frameworks like Express and Hono, specifically tailored for agent-to-agent (A2A) communication.

One issue I frequently noticed when developing A2A servers was managing consistent taskIds and contextIds across asynchronous operations, artifact streams, and task states. This complexity often leads to repetitive and error-prone code.

A2ALite simplifies these challenges by automatically handling:

Building a standalone AI agent is one thing, but getting a Python agent to seamlessly collaborate with a Go or Rust agent without custom glue code is the real challenge. I just published a new piece on the Google Cloud Community blog introducing the A2A Integration Test Kit (ITK) Dashboard! 📊 In the article, I dive into how the ITK verifies compatibility across different SDK implementations everyday, and how the new dashboard centralizes this data into a holistic interoperability matrix. Interoperability shouldn't be an afterthought, and this dashboard is a huge step in making that mission measura

A2A has been around for a while, but I haven’t seen the X community talking about it much. It almost got overshadowed by Claude Code and skills and subagents. Would love to know if anyone has tried creating agentic flows using A2A and what was their experience.

Did anyone see Anthropic's post about MCP tools being unreliable because lots of tools makes the context window explode? You're forgiven for not having seen it, because I've seen only one person mention it so far.

Part of that article is a gigantic duh, if you have tons of tools, the context for agentic requests will explode and there will be reliability issues and inaccurate responses. It's interesting that they're indirectly admitting that there are still issues with long context (which, isn't that a duh too?), but I kept thinking...isn't this one of the problems
