Antigravity CLI and Antigravity 2.0 Documentation

Antigravity's documentation is split into four product tracks that share one agent model. The Antigravity 2.0 track covers Overview, Getting Started, Build with Google, Feature Overview, Models, Projects, Remote Control, Settings, Agent Capabilities and Artifacts, and a Customizations section that gives MCP servers, Skills, Rules, Plugins, Hooks and Sidecars each their own reference page. The Antigravity CLI track is the one terminal users want: Installation and Auth, a step-by-step Tutorial, Using AGY CLI, Features, Migration, Prompting and Interaction, Artifacts, Managing Conversations, Agent Capabilities, Projects, Settings, AI Credits, Customizations and a full Commands reference covering slash commands such as `/agents`, `/codesearch` and `/diff`, plus headless mode and background tasks. Separate tracks document the Antigravity SDK, for building programmatically rather than interactively, and Antigravity for IDEs. The docs are versioned and move quickly: as of late August 2026 they list Antigravity 2.0 at v2.11.0, the CLI at v1.1.22, the SDK at v0.1.15 and the IDE extension at v2.5.5. The Migration section exists because Google gave no grace period when Gemini CLI stopped serving individual users on 18 June 2026, so any shell script, cron job or CI pipeline still invoking `gemini` simply broke. Google publishes and maintains this documentation directly, which makes it the authoritative source rather than a third-party write-up.

• ✓Install and authenticate the Go-based `agy` CLI and the Antigravity 2.0 desktop app
• ✓Migrate shell scripts, cron jobs and CI pipelines off the retired Gemini CLI binary
• ✓Run agents non-interactively in headless mode for CI/CD and scheduled automation
• ✓Extend an agent with MCP servers, Skills, Rules, Plugins, Hooks and Sidecars
• ✓Manage long-running conversations, background tasks and artifacts across multi-step agent runs
• ✓Scope agents to specific projects and folders, and drive them with Remote Control
• ✓Choose models per task and budget work against the AI Credits system
• ✓Build programmatically against the Antigravity SDK instead of the interactive CLI

• •This is the successor documentation that actually matters: Gemini CLI stopped serving free, Pro and Ultra users on 18 June 2026 with no grace period, so tutorials for the old tool are dead ends.
• •A dedicated Migration section is the single most useful page if you have `gemini` invocations sitting in CI or cron.
• •The customization surface is unusually deep for a vendor agent — MCP, Skills, Rules, Plugins, Hooks and Sidecars are each documented separately rather than lumped into one 'extensibility' page.
• •Explicitly versioned across four artifacts (app, CLI, SDK, IDE extension), so you can tell whether a page matches the binary you installed.
• •Read the permissions and agent-capability pages before granting broad access: Hacker News has documented an indirect prompt-injection data-exfiltration finding (Nov 2025, 768 points) and a whole-drive deletion incident (Dec 2025, 544 points).
• •Community reception is genuinely mixed — 'Google's Antigravity bait and switch' drew 771 points in May 2026 over the forced migration and the credit model. Worth reading before you standardize a team on it.
