VS Code previews agent plugins

This is a meaningful step toward treating agent setup like an ecosystem instead of a pile of ad hoc files. The upside is obvious: teams can package best-practice workflows, but the trust and supply-chain story matters because plugins can run code and expose external tools.

• –Bundling skills, commands, hooks, agents, and MCP servers into one installable unit removes a lot of setup friction
• –Marketplace discovery should make good agent workflows easier to reuse across repos and orgs
• –The feature is still preview, so the real test is whether plugin compatibility stays sane across VS Code, Copilot CLI, and other tools
• –Hooks and MCP servers raise the security bar, so review and trust prompts are not optional details
• –This pushes VS Code deeper into “agent platform” territory, not just editor plus chat
