Antigravity CLI v1.5.5

Antigravity CLI v1.5.5 was released on November 10, 2026.

Summary

Swarms are here in preview: spin up a coordinator and parallel workers that share a message board, watch them live in /swarm board, and never lose uncommitted work. Quota heavy, so tread carefully. What will your swarm build first?

Release Notes

• Added swarms as a preview: start one with /swarm <task> and the agent becomes a coordinator that adds worker agents, each in its own conversation, which work on the task in parallel and collaborate through a shared message board; workers can be forked from an existing member's conversation, run on any model in the /model picker, and pause instead of retrying when their model runs out of quota, and a monitor worker alerts the coordinator when the whole swarm stalls. /swarm is labeled (Preview & Quota Heavy) in the / menu because every worker is a separate agent that uses your quota.
• Added /swarm board, a full-screen live view of the current swarm that also opens with alt+s (rebindable as swarm.board), with a Roster of members showing each one's state and model, a Posts feed, and a Message pane that renders the selected post as Markdown; tab and shift+tab move between panes, z zooms the focused pane, enter shows or hides the message, [ and ] step through posts, p filters the feed to one member's posts and the posts that mention them, o opens a member's subagent details, f follows new posts, and esc backs out.
• Added a ● Swarm(<title>) row to the active-items tray below the prompt while a swarm runs, showing the latest post and the post count and then Done when the swarm finishes; press Enter on the row to open /swarm board, or alt+x (swarm.dismiss) to dismiss it.
• Added the ANTIGRAVITYDISABLEEMBEDDEDRIPGREP environment variable, which you can set to true to stop the CLI from extracting and running its bundled ripgrep, for example when endpoint security software blocks it, so searches use a ripgrep on your PATH or the built-in search instead.
• Added Gemini 4 Carbon (Low, Medium, and High) to /model and --model when you sign in with Application Default Credentials (AGYADCAUTH).
• Changed enterprise model gateway URLs to require https:// unless the gateway runs on the same machine (localhost, 127.0.0.0/8, or ::1); a remote gateway configured with a plain http:// URL is now rejected with an error instead of receiving your prompts unencrypted.
• Fixed agy plugin import turning Claude Code plugin commands into skills that did not load or were all named SKILL; each command now becomes a skill named after its folder, including commands with no frontmatter or with Claude Code-style values such as argument-hint: [base branch] [focus], and agy plugin validate no longer warns about the leftover commands/ folder.
• Fixed agy plugin import copying certain plugin's hooks/hooks.json unchanged, which caused the plugin's hooks to be skipped; PreToolUse, PostToolUse, Stop, and startup SessionStart hooks are now converted, with tool names in matchers mapped to built-in tools (for example Bash to runcommand) and a default 60-second timeout, and hooks with no equivalent are listed as warnings in the import summary.
• Fixed agy -p headless runs sometimes never exiting after printing their result when a background task, such as conversation title generation, got stuck; the CLI now finishes shutting down within 30 seconds.
• Fixed /teamwork writing run state into .agents/teamwork/ in your working directory, where two runs in the same workspace could overwrite each other; each run now keeps its state in its own folder under the CLI's app data directory.
• Fixed links to files in agent responses showing only the file name, which made the file's location impossible to tell in terminals that cannot open clickable links, such as Terminal.app, screen, or over SSH; labels now show the path relative to your working directory, relative to ~/, or the absolute path.
• Fixed enterprise model gateways that validate the request format rejecting every request, because the CLI sent a non-standard sessionId field in Gemini-format requests.
• Fixed subagents and swarm workers that get their own copy of a Git repository starting from the last commit and losing your uncommitted work; their worktree now includes your staged, unstaged, and untracked changes, and agents outside version control can give a subagent or worker an isolated copy of the workspace folder, for folders up to 100,000 entries and 4 GiB.
