AWS, GitHub, Microsoft, OpenAI and Vercel ship Agent Plugins 1.0.0
Agent Plugins 1.0.0 is a vendor-neutral plugin format — a plugin.json manifest, a skills/ folder, an mcp.json — published jointly by AWS, Anysphere, GitHub, Microsoft, OpenAI and Vercel, with ChatGPT, Cursor, GitHub Copilot, Kiro and VS Code supporting it at launch. The scope is narrow on purpose: packaging only, with install, permissions and distribution left to each client. Extension authors can package Skills and MCP servers once and carry them across every supporting client, and Google joining core maintenance on day one leaves few major agent vendors outside the standard.

A reusable component should not need to be repackaged for every client, so the format specifies only what a client needs to discover and load what is inside.
Why this matters
- → Extension authors package once, deploy everywhere — no client-specific rewrites
- → Vendor-neutral standard prevents lock-in across ChatGPT, Cursor, Copilot, VS Code
- → Lower barrier to entry for plugin ecosystem; AWS, Microsoft, OpenAI aligned on format
