Story 6 of 16 in the Thursday 29 October editionGoogle launches Plugin Marketplace in the Antigravity app and CLI
Google introduced a built-in Plugin Marketplace on 29 October 2026 across the Antigravity desktop IDE and Antigravity CLI, bundling agent skills, MCP servers, rules, lifecycle hooks, and custom agents into single-install packages.

Instead of configuring Model Context Protocol (MCP) endpoints, system prompts, and helper scripts piecemeal per repository, developers can browse and enable curated Google and partner bundles from the Customizations panel in the Antigravity app or from the terminal via agy plugin install and agy plugin list. Every package is defined by a plugin.json manifest that versions and distributes up to five primitives together, alongside local schema checks through agy plugin validate.
Five bundled primitives
Each plugin combines progressive-disclosure Skills (Markdown instructions loaded on demand so idle tools do not consume context tokens), pre-configured MCP server connections, persistent workspace Rules, specialist Custom Agents, and deterministic lifecycle Hooks triggered at SessionStart, PreToolUse, PostToolUse, PreInvocation, PostInvocation, and Stop. Twelve third-party launch partners shipped verified plugins on 29 October 2026: Atlassian, Canva, CrowdStrike, Databricks, Datadog, Dropbox, Figma, monday.com, Ping Identity, SentinelOne, Stripe, and Unity, alongside Google bundles for Gemini API, Android CLI, Firebase, Chrome DevTools, and Google Workspace.
