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.

3. Introduction
4. What is Antigravity? An agentic IDE from Google Beyond AI-assisted coding, it enables developers to operate at a higher level, managing AI agents across workspaces
6. Install & Configure
8. AI-powered IDE
9. Editor A familiar 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
10. Editor View AI-powered IDE Terminal Agent
11. Agent Side Panel – conversation mode
12. Agent Side Panel – models
13. Editor – auto-complete
14. Editor – tab to jump
15. Editor – command
16. Editor – explain & fix
17. Editor – send problems to agent
18. Editor – send terminal output to agent
19. Agent Manager
20. Agent Manager A higher level view into the work agents are doing under your guidance You can work across multiple workspaces, oversee dozens of agents simultaneously
21. Agent Manager View Workspaces Conversations Playground
22. Agent Manager – Workspaces Work across multiple workspaces (folders) simultaneously and in parallel Add a workspace with Open Workspace
23. Agent Manager – Conversations
24. Agent Manager – Playground An independent workspace for quick prototypes You can move playgrounds into a workspace later
25. Agent Manager – Inbox One stop shop to track all conversations in one place From the inbox, you can see if any of your conversations are awaiting your approval
26. Agent Manager – Inbox
27. Artifacts Task List Implementation Plan Code Diff Walkthrough Screenshot Browser Recording
29. 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
30. Task List
31. Implementation Plan Agent creates an implementation plan for technical changes within your codebase Meant to be reviewed by the user, unless Always Proceed is enabled
32. Implementation Plan
33. Code Diff As Antigravity works on a task, it’ll create code diffs for you to accept or reject
34. Code Diff
35. 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
36. Walkthrough
37. Screenshot & Recording Agent can take browser screenshots and recordings to verify functionality and add it to the walkthrough
38. Screenshot & Recording
39. Browser Agent
40. Browser agent Antigravity has the ability to open, read, and control a Chrome browser with a subagent in a separate browser profile Useful for browser based tasks, testing, and verification web apps, etc.
41. Browser agent First time, you’ll be prompted to install a Chrome extension
42. Customizations Rules Workflows Skills
43. Rules Rules help guide the behavior of the agent For example, you can add a rule for agent to follow a certain code style, or to always document methods
44. Workflows 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
45. Rules and Workflows
46. Skills An open standard for extending agent capabilities with best practices During a conversation, the agent sees a list of available skills and if it looks relevant to the task, the agent reads the full instructions and follows them
47. Define a Skill .agent/skills/my-skill/ ├─── SKILL.md # Main instructions (required) ├─── scripts/ # Helper scripts (optional) ├─── examples/ # Reference implementations (optional) └─── resources/ # Templates and other assets (optional) Workspace: <workspace-root>/.agent/skills/<skill-folder>/ Global: ~/.gemini/antigravity/skills/<skill-folder>/
48. Rules vs. Workflows vs. Skills Rules ≅ system instructions (always-on) Workflows ≅ saved prompts (user-triggered) Skills ≅ saved prompts, scripts, examples (agent-triggered)
49. Security & Control
50. Artifact Review Policy
51. Terminal Execution Policy
52. Terminal Allow/Deny Lists
53. File Access
54. Browser JavaScript Execution Policy & Allow List
55. Strict Mode When strict mode is enabled, several security measures are enforced by default: •Browser URL Allowlist/Denylist •Terminal, Browser, Artifact Review Policies •File System Access
