AGNTCon + MCPCon Japan 2026

Tool descriptions tell an agent what a tool can do, but not how to orchestrate those capabilities toward a goal, or supplement them with specialized knowledge. Agent skills have become a popular and accessible way to close that gap, and many organizations now ship skills alongside their servers. The community effort to standardize that pairing has drawn 50+ contributors from 25+ organizations across the entire AI infrastructure stack: cloud platforms, data platforms, enterprise SaaS, gateways, and independent implementers. This talk covers where that momentum is headed, and how Extensions let the protocol evolve to meet real-world demand while balancing the stability, security, and developer experience that production systems require.
