Google Antigravity adds shared projects, safer browser use, and agent swarms

Google Antigravity shipped a set of project, browser, layout, and CLI changes from November 6 to 12, 2026. The updates include new ways to share project context across code and documents, controls over browser-agent downloads, cross-agent setup imports, and an explicitly preview, quota-heavy swarm workflow.

Connect code and documents in one Project

Antigravity announced that a single Project can connect a GitHub repository and a Google Drive folder, giving the agent read and write access to code and documents in the same conversation. The announcement says users can start on the web, continue in the app, and have remote plugins follow them across surfaces. These details come from Antigravity’s official announcement; check the current product’s connector prompts and permissions before granting access.

Choose a Knowledge Work layout

Antigravity’s November 9 changelog adds a Knowledge Work interface layout for research, writing, and everyday tasks. It hides code changes and developer tools, simplifies agent progress and command descriptions, and can be selected under Settings > General > Interface Layout. The changelog says this layout is not available on business or enterprise accounts. (https://antigravity.google/docs/changelog.md)

The same release lets Antigravity import MCP servers, skills, custom commands, subagents, and instruction files from coding agents such as Claude Code, Codex, and Cursor into a plugin the user owns. This is an import path for existing setups, not a claim that those agents’ plugins behave identically after import. (https://antigravity.google/docs/changelog.md)

Browser-agent approvals and controls

Version 2.31.0, dated November 9, pauses browser-agent downloads until the user approves them and prevents pages controlled by the browser agent from locking the mouse pointer or keyboard. Antigravity’s November 11 announcement also says users choose what the agent logs into and that downloads pause for approval, while the agent can run multiple browser tasks at once. Browser use is rolling out, so check current availability in the app. (https://antigravity.google/docs/changelog.md; https://x.com/antigravity/status/2120556423474028576)

Agent swarms in the Antigravity CLI

Antigravity announced /swarm for its desktop app and CLI on November 10; the CLI changelog documents the command as a preview. A coordinator can add worker agents that run in separate conversations and collaborate through a shared message board; /swarm board opens a live view of their state and posts. The changelog labels the feature “Preview & Quota Heavy” because every worker is a separate agent that uses quota. Workers pause rather than retrying when their model runs out of quota. Treat this as an experimental workflow and account for per-agent usage before starting a swarm. (https://antigravity.google/docs/changelog.md; https://x.com/antigravity/status/2120279327589773639)

Version 1.5.6 adds swarm-board visuals, including a roster and status indicators. The release notes also say pay-as-you-go Google Cloud accounts using Application Default Credentials receive the same permission settings as other pay-as-you-go accounts, making Auto mode available; Gemini Enterprise accounts continue to use organization-controlled permissions. (https://antigravity.google/docs/changelog.md)

CLI mode and gateway safeguards

Antigravity CLI 1.5.7, dated November 12, changes the default Agent Mode from Default to Auto for sessions without a saved mode, wherever Auto is available. To keep the previous behavior, choose Default in /config; a strict Tool Permission setting continues to require approval for file edits. (https://antigravity.google/docs/changelog.md)

Version 1.5.5 also requires remote enterprise model gateways to use HTTPS. Plain HTTP is rejected unless the gateway runs locally on the same machine, preventing prompts from being sent to a remote gateway without transport encryption. (https://antigravity.google/docs/changelog.md)

Gemini 4 model availability

Google’s November model announcements add product-specific access paths in Antigravity. Gemini 4 Carbon is rolling out to Google AI Ultra subscribers; Antigravity says the rollout includes its desktop app, CLI, and IDE extensions. The changelog separately documents Carbon in the model selector for users signed in with Google Cloud Application Default Credentials. (https://blog.google/innovation-and-ai/models-and-research/gemini-models/gemini-4-carbon-now-available/; https://x.com/antigravity/status/2120188336056733746; https://antigravity.google/docs/changelog.md)

Google’s Hydrogen developer page says paid AI Pro or Ultra subscribers can try Hydrogen in Antigravity, while Antigravity’s account announced a rollout to paid plans including Pro, Ultra, and enterprise customers. Check current workspace eligibility because these announcements describe separate product access paths. See our Gemini API November update for model and API details.
