Getting started with Google Antigravity

Google Antigravity transforms your regular IDE into an agentic development platform. Beyond basic tab completion, Antigravity offers an intuitive, artifact-based approach to monitoring and providing feedback to agents. By utilizing rules, workflows, and skills, you can fully customize the environment to your team’s best practices, while a dedicated browser subagent handles tasks outside the editor. Last but not least, its Agent Manager can spin up and coordinate multiple parallel agents across various workflows, allowing you to work at a higher level than the code itself.

1. Getting Started with https://antigravity.google
2. Who am I? Mete Atamel Developer Advocate @ Google Cloud atamel.dev speakerdeck.com/meteatamel @meteatamel
3. What is Antigravity? An agentic development platform from Google allowing anyone to build
4. Antigravity Platform  Antigravity App  Antigravity IDE & Antigravity IDE Extensions  Antigravity CLI  Antigravity SDK
5. Antigravity App
6. Antigravity App Your command center to manage multiple local agents across multiple folders Group conversations & folders into projects and operate across them in parallel
8. Models
9. Permission presets
11. Projects A project defines the filesystem and security boundaries for the agent Multi-folder & worktree support, scoped settings and permissions that the agent respects
12. Review and Terminal Review diffs, stage & commit with Git, and quote or comment on lines (no inline editing) Built-in terminal and browser in the side panel
13. Context & Attachments Use @ to reference files, folders, symbols, docs, and subagents in prompts Select lines in diffs or artifacts to quote directly into chat, and attach images, PDFs (with built-in viewer), audio, or video
14. Automations Automate routine tasks in Automations panel Define a cron schedule and the agents start and run autonomously in the background in their own project
15. Automations
16. Customizations Marketplace of Plugins from Google Workspace & Build with Google, plus Skills, Rules, Hooks, and MCP servers
17. Customizations
18. Slash commands /plan: Plan carefully before executing a task /grill-me: Interview me to align on a plan /goal: Run until the task is finished /boost: Explore parallel solutions for hard problems /teamwork: Assemble a multi-agent team /btw: Ask a side question without interrupting /browser: Invoke a browser subagent /learn: Distill into persistent Rules or Skills /plugin: Create and manage plugins /schedule: Schedule a task /compact: Summarize history to free up context window
19. Subagents Subagents are instantiated dynamically to tackle parallel parts of complex problems
20. Subagents Pre-packaged with specialized subagents: research, browser, image-generator, self You can define and use your own custom agents
21. Browser Subagent Antigravity has the ability to open and control a Chrome browser with /browser Requires Chrome and a permission to start a debugging session
22. Teamwork Use /teamwork to dynamically assemble a custom team of specialized subagents Each agent gets its own role, system prompt, and isolated branch, communicating peer-to-peer
23. Antigravity IDE Antigravity IDE Extensions
24. Antigravity IDE (deprioritized) A VS Code-based AI-assisted editor with an agent side panel and terminal Auto-complete, tab to import, tab to jump, commands, explain & fix, send problems to agent, send terminal output to agent
25. AI-powered IDE Agent Terminal
26. Models
27. Auto complete
28. Tab to import
29. Tab to jump
30. Explain & fix
31. Send (problems) to agent
32. Send terminal output to agent
33. Antigravity IDE Extensions IDE Extensions with Antigravity agent side panel (but no AI-assistance in the editor) Extensions for: Visual Studio Code, Visual Studio, JetBrains, Zed, Xcode, Eclipse
34. Antigravity IDE Extensions
35. Antigravity IDE Extensions
36. Antigravity CLI
37. Antigravity CLI Terminal-first surface to work with Antigravity
38. Antigravity CLI Interactive TUI (agy) and headless mode (agy -p) with JSON/stream output for CI/CD Run inline shell commands (!) or --dangerously-skip-permissions for Turbo mode
39. Antigravity SDK
40. Antigravity SDK The Antigravity SDK gives you the same tools, agent loop, and context management that power Antigravity, programmable in Python
41. Antigravity SDK import asyncio from google.antigravity import Agent, LocalAgentConfig async def main(): config = LocalAgentConfig() async with Agent(config) as agent: response = await agent.chat("Explain the repository layout.") print(await response.text()) if __name__ == "__main__": asyncio.run(main())
43. Artifacts Task List Implementation Plan Code Diff Walkthrough Screenshot & Recording Generative UI
45. Task List Used by the agent to keep track and monitor progress with action items Typically, you do not need to directly interact with the task list
46. Task List
47. Implementation Plan When /plan is used, agent creates an implementation plan for changes for user to review
48. Implementation Plan
49. Code Diff As Antigravity works on a task, it’ll create code diffs for you to accept or reject
50. Code Diff
51. Walkthrough Agent creates a walkthrough after a task is done Summary of the code changes and steps taken (screenshots, browser recordings) to verify the changes
52. Walkthrough
53. Screenshot & Recording Agent can take browser screenshots and recordings to verify functionality and add it to the walkthrough
54. Screenshot & Recording
55. Generative UI Agent can generate interactive HTML/CSS/JS widgets rendered inline in chat or as standalone artifacts Ideal for interactive diagrams, charts, data visualizations, and visual walkthroughs (/generative_ui)
56. Customizations Skills MCP Servers Rules (& Workflows) Hooks Sidecars Custom Agents Plugins
57. Skills An open standard for extending agent capabilities with best practices During a conversation, the agent sees a list of available skills and decides which one to use for the task
58. Define a Skill my-skill/ ├─── SKILL.md ├─── scripts/ ├─── examples/ ├─── resources/ └─── references/ # Main instructions (required) # Helper scripts (optional) # Reference implementations (optional) # Templates and other assets (optional) # Additional documentation (optional)
59. MCP Servers Antigravity supports Model Context Protocol (MCP) servers Provides the AI with real-time context beyond just the files open in your editor
60. MCP Servers
61. Rules Rules help guide the behavior of the agent with AGENTS.md, GEMINI.md, or .agents/rules/*.md files For example, you can add a rule to follow a certain code style, or to always document methods
62. Workflows (deprioritized) Workflows are saved prompts that you can trigger on demand with / with the agent For example, you can add a workflow to generate unit tests on demand
63. Rules vs. Skills Rules ≅ guardrails & instructions (always-on, glob, manual, or model-triggered) Skills ≅ multi-step workflows, scripts, examples (agent-triggered)
64. Hooks
65. Sidecars
66. Custom Agents
67. Plugins
68. Plugin Marketplace
69. Where does Antigravity look for configurations? atamel.dev/posts/2026/08-21_where_agy_configuration_summary/
70. Permissions
71. Hierarchy of permissions Global (User) Level The highest layer. Establishes baseline security policies, default safe directories, and absolute restrictions across all workspaces. Project Level Inherits and refines global policies. Configures settings for specific repositories, workspace-level permissions, and local trusted tools. Conversation (Session) Level The most granular layer. Dynamically manages individual execution sessions, temporary folder access, and on-the-fly execution approvals.
72. Permissions Permission Preset (Personal) Command Auto Execution (Enterprise) Outside of Folders Artifact Review Policy Request Review ✓ Default (Sandbox On) DEFAULT Auto (Preview) • Turbo ✓ Always Ask DEFAULT Allow Deny ✓ Require Review DEFAULT Proceed in Sandbox Always Proceed ✓ Always Ask DEFAULT Always Proceed
73. Permissions: Deny > Ask > Allow File Access Rules Ask Allow Deny Network Access Rules Terminal Commands Commands Outside Sandbox Ask Ask Ask Allow Allow Allow Deny Deny Deny MCP Tools Ask Allow Deny
74. Permissions Browser Javascript Execution Policy Disable ✓ Request Review DEFAULT Always Proceed Browser Actuation Rules (Execute URLs) Allow Ask Deny
