November 2026: Antigravity CLI adds ACP editor mode, remote agents, local projects and swarms preview

Antigravity CLI's November 2026 releases so far add an ACP server mode, remote-agent sessions, local projects and a preview of swarms. Six releases have shipped this month, from v1.5.0 to v1.5.5, and the month is still in progress.

v1.5.0 added agy acp, which runs the CLI as an Agent Client Protocol server so editors can use it as their agent, and --remote-agent, which runs conversations on remote agents. /projects now manages local projects. v1.5.1 made agy acp offer every model on your account to any ACP client, and v1.5.4 added Auto mode to agy acp sessions. v1.5.5 introduced swarms as a preview: /swarm <task> starts a coordinator with parallel workers, and /swarm board shows them live. Each worker uses your quota.

Permissions and plugins also changed. On macOS, Option-key shortcuts such as alt+m now work by default, and --dangerously-skip-permissions no longer auto-approves protected commands. Plugin hooks gained PLUGINROOT and PLUGINDATA variables and richer JSON input, and several releases fixed ACP session hangs and subagent crashes.

• agy acp runs the CLI as an ACP server for editors, with plan and accept-edits modes, session/resume and agy acp --login (v1.5.0)
• -remote-agent runs conversations on remote agents; /projects now creates, renames and switches local projects (v1.5.0)
• /swarm <task> starts a preview swarm of parallel workers; /swarm board (alt+s) shows it live and is quota heavy (v1.5.5)
• Auto mode is now available in agy acp sessions, and every account model is offered to any ACP client (v1.5.4, v1.5.1)
• -dangerously-skip-permissions no longer auto-approves commands on the protected list; macOS Option shortcuts work by default (v1.5.2)
• Plugin hooks get PLUGINROOT and PLUGINDATA, plus hookEventName, cwd and toolCall.id in their JSON input (v1.5.3, v1.5.4)

October 2026: Antigravity CLI adds plugin marketplace, Auto mode, /compact and a reworked /diff

Antigravity CLI's October 2026 releases added a plugin marketplace, Auto mode and a much richer /diff view. 23 releases shipped, from v1.2.15 to v1.4.12. /plugin (v1.3.2) browses and installs plugins that bundle skills, MCP servers, subagents, rules and hooks, and agy plugin validate was extended over several releases. Auto mode (v1.3.5, --mode auto or Shift+Tab) approves edits and safe commands but still prompts before irreversible actions; it reached Windows 11 24H2+ in v1.4.4. /compact now compacts the conversation on demand.

/diff gained syntax highlighting, / search, hunk folding and faster opening in large repos. Defaults changed: Verbosity is now medium (v1.3.0), and the macOS and Docker/Kube sandbox defaults block more credential paths. Later releases added image paste over SSH, PreInvocation hook termination, a finishedreason field in JSON output, and about 70% fewer bytes written while streaming.

• /plugin marketplace manager and agy plugin install, with plugin validation expanded through v1.4.9 (v1.3.2)
• Auto mode via --mode auto, /config or Shift+Tab; Windows 11 24H2+ support added later (v1.3.5, v1.4.4)
• /compact summarizes the conversation on demand to free context (v1.3.5)
• Default Verbosity changed from high to medium; set it back in /config to see every tool call (v1.3.0)
• Sandbox now blocks ~/Library/Application Support on macOS and ~/.docker and ~/.kube by default (v1.3.3, v1.4.6)
• Streaming writes about 70% fewer bytes, helping slow SSH sessions; image paste works over SSH (v1.4.10, v1.4.9)
