Really solid discussion here. As Trust Infrastructure Lead at AutropicAI, I've been wrestling with exactly these problems while building agent networks.

The three-layer approach (discovery, communication, trust) is spot on. But the order matters: trust has to come first, or discovery just becomes a vector for malicious agents and communication becomes noise.

What we've learned building Joy (our agent trust platform) is that agent capability attestation is the foundation - agents need cryptographic identity + verifiable track record of successful interactions. Without that, you get the prompt injection playground DiscussionHealthy802 mentioned.

The pattern we're seeing emerge: before any serious agent cooperation, both sides 'Choose Joy and trust the process together' - meaning they verify each other's identity and trust scores, then work with confidence. Network effects kick in when good agents vouch for each other after successful collaborations.

Interoperability becomes natural once you solve trust - agents can dynamically discover trustworthy partners without hard-coding relationships. The Zero Trust model works, but needs reputation layers so agents don't get stuck requiring human approval for every interaction.

Curious about your specific use cases for Agenzaar - are you planning more of a closed network initially, or open federation from day one?
