Understanding the AntiGravity IDE Interface

The Dual-Interface Design

AntiGravity IDE uniquely combines two interfaces that work seamlessly together:

1. Agent Interface (Left Panel)

• Natural Language Input: Describe what you want to build
• Agent Conversations: Chat with AI agents about code
• Task List: See what agents are working on in real-time
• Artifacts View: Interactive prototypes and visualizations
• Knowledge Items: Project context and documentation

2. Code Interface (Right Panel)

• File Explorer: Traditional directory tree
• Code Editor: Syntax highlighting, IntelliSense, all standard features
• Terminal: Command line access
• Git Integration: Version control UI
• Debugging Tools: Breakpoints, watch variables, etc.

Key Interface Components in 2026

The Command Palette (Cmd/Ctrl + K)

Central hub for all actions:

• Type natural language commands: "Create a login page"
• Access traditional IDE functions: "Search files"
• Manage agents: "Show active agents"
• Quick navigation: "Go to function getUserData"

The Agent Panel

View and manage AI agents working on your project:

Agent Type	Responsibility	When Active
Architect Agent	System design, code structure, patterns	New features, refactoring
Code Agent	Writing and modifying code	All development tasks
Test Agent	Writing and running tests	When testing enabled
Debug Agent	Finding and fixing bugs	Error investigation
Documentation Agent	Writing docs, comments, READMEs	Documentation tasks
Refactor Agent	Code improvement without behavior change	Code quality tasks

Artifacts Viewer

Interactive pane showing executable outputs:

• Live web applications (React, Vue, vanilla JS)
• Data visualizations (charts, graphs, maps)
• API explorers and documentation
• Database schema viewers
• UI component libraries

Artifacts are more than previews—they're working software you can interact with, modify through conversation, and deploy directly.

Knowledge Items Panel

Project memory system where you store:

• Design Decisions: Why you chose specific approaches
• Code Patterns: Project-specific conventions
• Architecture Docs: System structure and data flow
• API Contracts: Interface definitions
• Team Guidelines: Coding standards and practices

Agents reference knowledge items when making decisions, ensuring consistency across the codebase.

How to Work with AI Agents in AntiGravity IDE

Starting Your First Agent Task

Example 1: Creating a New Feature

1. Open the Agent panel (Cmd/Ctrl + Shift + A)
2. Type your request: "Create a user authentication system with email/password login, JWT tokens, and password reset functionality"
3. Press Enter
4. Watch as multiple agents activate:
   • Architect Agent designs the auth system structure
   • Code Agent implements backend endpoints and frontend components
   • Test Agent writes unit and integration tests
   • Documentation Agent creates API docs
5. Review the plan agents propose before they start coding
6. Approve or refine the approach
7. Agents execute in parallel, updating you on progress

Conversational Refinement

You don't need perfect specifications upfront. Refine as agents work:

Multi-Agent Parallel Execution

AntiGravity's breakthrough feature: agents work simultaneously on independent tasks.

Example: E-commerce Platform

What happens:

• Agent 1: Implements product listing and search (backend + frontend)
• Agent 2: Creates filter UI and logic (parallel to Agent 1)
• Agent 3: Builds shopping cart state management
• Agent 4: Develops checkout flow and payment integration
• Agent 5: Writes tests for all components

All work happens simultaneously. Agents coordinate to avoid conflicts through shared context understanding.

Reviewing and Approving Agent Work

AntiGravity IDE provides multiple review mechanisms:

1. Plan Review (Before Execution)

• Agents propose implementation plan
• See file changes, architecture decisions, dependencies
• Approve, request changes, or reject

2. Progressive Review (During Execution)

• Watch agents work in real-time
• Pause at any point to provide feedback
• Course-correct without starting over

3. Diff Review (After Completion)

• Standard Git-style diff view
• Review all changes before committing
• Request modifications to specific sections

Agent Collaboration Modes

Mode	Agent Autonomy	Your Involvement	Best For
Full Auto	Complete	Review final result only	Well-defined tasks, boilerplate
Collaborative	High with checkpoints	Approve major decisions	Complex features, new architecture
Supervised	Medium, frequent confirmations	Approve each file/function	Critical systems, learning projects
Assisted	Low, suggestions only	You write code, agents help	Fine-grained control, legacy code

How to Use Artifacts for Rapid Prototyping

Artifacts are AntiGravity IDE's most visually impressive feature—they turn conversations into interactive, working software instantly.

What Artifacts Can Create in 2026

1. Interactive Web Applications

• Full React/Vue/Svelte apps

Creating Your First Artifact

What happens:

1. Agent creates React component with Recharts library
2. Fetches mock data or connects to real API
3. Builds interactive chart with tooltips, legends, zoom
4. Artifact appears in viewer—fully functional and interactive
5. You can immediately test, refine, or export

Iterating on Artifacts

The real power: conversational iteration.

From Artifact to Production

When you're satisfied with an artifact:

1. Click "Add to Project" button
2. Choose destination (new component, existing file, new page)
3. Agent integrates code with proper imports and routing
4. Artifact becomes part of your production codebase
5. Deploy like any other component

How to Use Knowledge Items for Project Memory

Knowledge Items are AntiGravity's solution to maintaining context across long-term projects. They act as the project's memory, ensuring agents make consistent decisions aligned with your architecture and standards.

Types of Knowledge Items

1. Architecture Documents

• System design and component relationships
• Data flow diagrams
• Technology stack decisions
• Deployment architecture

2. Coding Conventions

• Naming patterns (camelCase, snake_case, etc.)
• File organization structure
• Error handling patterns
• Comment and documentation standards

3. API Contracts

• Endpoint specifications
• Request/response schemas
• Authentication requirements
• Rate limiting rules

4. Business Logic

• Domain-specific rules
• Calculation formulas
• Workflow definitions
• Validation criteria

Creating Knowledge Items

Method 1: From Conversation

1. During agent chat, click "Save as Knowledge Item"
2. Name the item (e.g., "Authentication Flow")
3. Add tags for categorization
4. Item saved for future agent reference

Method 2: Manual Creation

1. Open Knowledge Items panel (Cmd/Ctrl + Shift + K)
2. Click "New Item"
3. Choose type (Architecture, Convention, API, Business Logic)
4. Write or paste content (supports Markdown)
5. Save with descriptive title and tags

Method 3: Auto-Generated

Ask agents to document decisions:

Agent creates structured documentation automatically.

How Agents Use Knowledge Items

• Before implementing features, agents scan relevant knowledge items
• Apply documented patterns and conventions automatically
• Flag potential conflicts with established architecture
• Suggest knowledge item updates when discovering new patterns

Knowledge Item Best Practices

1. Document Decisions, Not Code: Focus on "why" rather than "what"
2. Keep Updated: Revise items as project evolves
3. Use Clear Titles: Make items easy to find and reference
4. Link Related Items: Create connections between related concepts
5. Version Important Items: Track changes to critical documentation

AntiGravity IDE Best Practices for 2026

1. Write Clear, Specific Requests

Less effective: "Make a login page"

More effective: "Create a login page with email/password fields, remember me checkbox, forgot password link, and Google OAuth button. Use our existing auth service at /api/auth. Match the design system in design-tokens.css"

2. Leverage Multi-Agent Parallelism

Break large tasks into independent subtasks:

• "Build user dashboard" → Split into: "user profile component", "activity feed", "settings panel", "analytics widgets"
• Agents work simultaneously on each part
• Dramatically faster completion

3. Build Knowledge Items Early

• Document architecture decisions from day one
• Establish coding conventions before agents write code
• Create API contracts before implementation
• Agents produce more consistent code with upfront context

4. Use Artifacts for Exploration

• Test UI ideas as artifacts before committing to codebase
• Explore data visualization approaches interactively
• Prototype user flows without touching production code
• Only integrate artifacts when you're satisfied

5. Review Agent Plans Before Execution

• Always review proposed implementation plans
• Verify architectural alignment
• Catch potential issues before code is written
• Cheaper to fix plans than fix code

6. Combine Modes Strategically

Task Type	Recommended Mode	Reasoning
New features	Collaborative	Balance speed with oversight
Boilerplate/CRUD	Full Auto	Maximize efficiency for repetitive work
Critical systems (auth, payments)	Supervised	Extra review for high-risk code
Bug fixes	Assisted	You diagnose, agents help implement
Refactoring	Collaborative	Verify behavior preservation

7. Version Control Integration

• Commit agent-generated code in logical units
• Review diffs before pushing
• Use descriptive commit messages (agents can generate these)
• Create feature branches for agent experiments

8. Testing and Quality

• Enable Test Agent for critical features
• Review generated tests—they're usually good but not perfect
• Add edge cases agents might miss
• Run full test suite before merging agent work
