Re: Proposal: agent.json universal manifest + Agent Quality Graph for trust scoring

Hi Takayuki,

Thanks for the detailed proposal on agent.json and the Agent Quality
Graph—this is thoughtful work that addresses real fragmentation in the
agent ecosystem. The idea of a universal manifest format with a well-known
URI convention is compelling, and the PageRank-style trust scoring approach
is a natural fit for evaluating delegation reliability.

I'd note that the strongest case for adoption will likely hinge on how
seamlessly agent.json integrates with existing registries (Smithery, MCP
Registry, etc.) without requiring them to migrate their current schemas. If
you're able to demonstrate backward compatibility or a lightweight adoption
path, that could accelerate uptake significantly.

Best,
Ben
