Back in August, I wrote Where does Antigravity look for Plugins? to explain how plugins bundle skills, rules, subagents, hooks, MCP servers, and sidecars into a single unit. At the time, installing a plugin meant pointing Antigravity to a GitHub repository or a local directory path.
This week, the team launched the Antigravity Plugin Marketplace: a curated catalog of first-party Google plugins and third-party partner plugins built directly into the Antigravity UI and CLI.
Instead of just listing what is in the marketplace, I wanted to share a real workflow that saved me hours this week: using the Google Slides plugin to audit and update my 80+ slide Getting Started with Google Antigravity presentation against the latest documentation.
What is the Antigravity Plugin Marketplace?
The Antigravity Plugin Marketplace makes discovering, installing, and authenticating plugins a one-click experience across both the Antigravity App/IDE and the agy CLI:
- In the Antigravity App / IDE: Open the Agent side panel, click … at the top right, navigate toCustomizations -> Plugins, and switch to the Marketplace tab.
- In the Antigravity CLI (agy): Run the /plugin slash command and switch to the Discover tab.
Here is what the Marketplace tab looks like under Customizations in the Antigravity UI:
Plugins are organized into curated shelves:
- Google Workspace: Google Docs, Google Sheets, Google Slides, Google Drive, and Google Calendar.
- Build with Google: Gemini API, Chrome DevTools, Android CLI, and Google Cloud Developer.
- Design, Creative & Media: Canva, Figma, and Mobbin.
- Productivity & Project Management: Atlassian Teamwork Graph CLI, Dropbox, and Linear.
- Cloud Hosting & Deployment: Netlify, Railway, and Vercel.
- Developer Tools & Business: Auth0, Base44, Browserbase, Bigin, Databricks, and Intercom.
Better yet, the marketplace handles authentication and configuration in place. For plugins that require an external account-like Google Workspace-you click Sign in directly on the plugin card, complete the OAuth flow in your browser, and Antigravity manages the credentials automatically. You can even connect multiple accounts (for example, work and personal) and switch between them.
Installing the Google Slides Plugin
If you give technical talks about fast-moving AI tools, you know the pain of keeping slide decks up to date. Antigravity ships multiple releases every week, which means screenshots, model names, CLI flags, and feature lists in my Getting Started with Google Antigravity deck start drifting out of date almost immediately.
Previously, auditing a Google Slides presentation meant exporting a PDF or copying slide text manually, asking an LLM what was outdated, and then manually clicking through 80+ slides in the browser to apply the fixes.
With the Google Slides plugin from the Google Workspace shelf, Antigravity gets:
- A dedicated gslides skill that teaches the agent how to read, design, and mutate presentations safely.
- A sandboxed gslides CLI separated into gslides readonly (for reading slides, inspecting page elements, and exporting PNG thumbnails) andgslides mutate (for updating text, inserting slides, and replacing images).
- Managed Google OAuth authentication so it can access your presentation directly via its Google Slides URL.
After installing the Google Slides plugin (and the Google Drive plugin) from the marketplace and signing in with my Google account, I was ready to put it to the test.
Auditing My Antigravity Slides Against the Docs
I pasted the Google Slides link to my presentation into Antigravity and gave it a simple prompt:
Can you check my Getting Started with Google Antigravity slides
(https://docs.google.com/presentation/d/<presentation-id>/edit)
against the latest Antigravity documentation and let me know if
there are any errors, outdated slides, or missing new features?
Antigravity used gslides readonly read to inspect all 81 slides in my deck, cross-referenced every slide against its built-in documentation skills ( antigravity-guide and agy-customizations), and came back with a structured audit report broken down into three categories:
- Wrong, outdated, or inconsistent slides
- Missing major features introduced in recent releases
- Outdated screenshots and sketchnote diagrams
Once I reviewed the report and gave the green light, Antigravity updated the live presentation directly. Here is what it caught and fixed.
First, Antigravity used gslides mutate replace-text and gslides mutate batch to fix factual drift and typos across existing slides without disturbing the slide formatting.
For example, it updated my permission presets slide to include all four current presets ( Request Review, Default, Auto (Preview), and Turbo), refreshed the IDE and subagent lists ( Eclipse support and the image-generator subagent), and updated the Skills and Rules slides with the references/ directory and all four rule trigger types ( always-on, glob, manual, and model-triggered). It even caught a doubled-quote Python syntax typo in an SDK code snippet and noticed that speaker notes on one slide had been accidentally copy-pasted from an earlier slide.
2. Adding Missing Features as New Slides
Next, Antigravity pointed out six major capabilities that had shipped since I first created the deck: Context & Attachments (@ mentions, diff line quoting, and multimedia attachments), Slash Commands (/plan, /grill-me,/goal, /boost, /teamwork, /btw), Teamwork (peer-to-peer subagent teams), Generative UI (inline interactive HTML/JS widgets), the Plugin Marketplace, and Enterprise Identity (BYO GCP project and SSO/WIF).
When I asked it to add slides for them, it inspected the exact typography ( Poppins headings, Roboto body, Roboto Mono code blocks, and #1976D2 accents) of my existing deck, inserted six new slides in the right sections, and ran gslides readonly export-thumbnail to visually verify every new slide for text overflow or alignment issues.
Here is the new Plugin Marketplace slide that Antigravity inserted into the presentation:
The most impressive part of the workflow happened when we got to the image-only slides. During its initial audit, Antigravity noticed that even on slides with no editable text boxes, the embedded screenshots and hand-drawn sketchnotes had outdated details.
I asked:
I like the updates, can you also update the images in the image-only
slides with the suggestions you had?
Antigravity extracted the images from those slides, spawned image-generator subagents in parallel to surgically edit each image while preserving its exact visual style, uploaded the updated images to Google Drive, and swapped them into the presentation.
Across those image-only slides, the subagents updated the dark-mode model selector screenshots to show Gemini 4 Argon Medium, refreshed the permission format table screenshot, updated my Hooks sketchnote diagram from "5 Critical Event Triggers" to "6 Critical Event Triggers" (adding Session Start to the flow), and updated my Plugins sketchnote diagram so Sidecars are included inside the AGY PLUGIN bundle instead of crossed out.
Here is the updated Hooks slide showing all 6 event triggers in the original hand-drawn sketchnote style:
And here is the updated Plugins slide with Sidecars added into the plugin bundle diagram:
Wrapping up
What used to be a tedious multi-hour chore of cross-checking release notes and manually editing slides turned into a single conversation. Having first-party Google Workspace plugins available directly in the Antigravity Plugin Marketplace-combined with documentation skills and image-generator subagents-makes it effortless to connect Antigravity to the docs, spreadsheets, and presentations where your day-to-day work actually lives.
