Agent Plugins 1.0: One Package Format That Works Across ChatGPT, Copilot, Cursor, VS Code, and Kiro

A single plugin.json + skills/ + mcp.json directory now installs into GitHub Copilot, VS Code, ChatGPT, Codex, Cursor, and Kiro — no separate manifest per client.

Agent Plugins 1.0 is an open standard published August 6 with AWS, Anysphere, Microsoft, OpenAI, Vercel, and Google as co-maintainers. It bundles agent skills and MCP servers into one installable format governed independently of any vendor. Build a deployment runbook skill with its MCP tool integration once; your whole team gets it on all their coding agents without you maintaining a separate manifest for each one.

Why it matters: Any team-specific skill or internal MCP integration you build now becomes portable — publish it to a skills registry or a shared repo directory and it works wherever your engineers happen to be.
