Google Antigravity adds /swarm command for parallel coding agents

Google announced on November 10, 2026, that its Antigravity coding environment, available as both a desktop app and a command line tool, added a new /swarm slash command for orchestrating multiple parallel coding agents, according to Google Antigravity's announcement.

What changes with /swarm

• /swarm is a new slash command available in both the Antigravity desktop app and its CLI.
• A coordinator agent spins up named parallel worker agents, each working in its own isolated git worktree so edits do not collide.
• Dedicated adversarial verifier agents run tests and challenge the diffs produced by worker agents.
• Agents coordinate through a shared live message board with three views, Board, Members, and Graph, reachable in the CLI with /swarm board or the Alt+S shortcut.
• Idle agents cost zero tokens until activated, and each worker role can be pinned to a different model, for example mixing Gemini 4 Carbon with lighter models.
• The feature rolled out in preview on November 10, 2026, the same day Gemini 4 Carbon became more broadly available, and is open to Google AI Pro and Google AI Ultra subscribers.

What it means for people who build with AI

This gives Antigravity users a distinct multi-agent orchestration primitive, combining isolated worktrees with adversarial verification, that directly competes with the multi-agent patterns already found in Claude Code and Codex. Developers running large parallel refactors gain a way to split work across named agents without merge conflicts, while a separate verifier agent checks the result instead of relying on a single agent's self-review.

Testing and quota limits

Google says it tested swarms internally for five weeks on multi-package migrations, cross-subsystem investigations, and architectural redesigns. The company also warns that running parallel multi-agent swarms consumes quota far faster than a standard chat session, so Google AI Pro and Google AI Ultra subscribers should budget their usage accordingly.
