Agent Plugins Get a Shared Standard
Agent extensions are beginning to acquire a portable software contract. OpenAI, Amazon, Microsoft, Cursor and Vercel backed a shared Agent Plugins package combining skills and MCP servers; developers immediately requested native GitHub CLI support, while a separate Channels SDK demonstrated agents retaining their tools and logic across workplace chat systems. Together with AWS packaging policy workflows as reusable skills, the evidence moves agent-ready software from an interface hypothesis into an emerging distribution standard.
