What this post added

Introduces Agent Plugins 1.0.0, an open, vendor-neutral specification for packaging Agent Skills and MCP servers into portable plugins. This specification defines a standardized directory structure (e.g., `skills/`, `mcp.json`) and a simple `plugin.json` manifest to ensure portability across different agent clients. Google is joining as a Core Maintainer and integrating support into its products, including Agents CLI and Data Agent Kit.
