Antigravity Agent Manager

Overview

A playbook for orchestrating multi-agent systems using the standalone Antigravity 2.0 Agent Manager (white icon) in parallel with the Antigravity IDE (black icon).

Starting with version 2.0, Google decoupled the Agent Manager from the main IDE interface, removing the "Open Agent Manager" button. This skill outlines how to install, configure, and operate the two environments side-by-side to direct multiple AI agents on front-end and back-end projects simultaneously.

When to Use This Skill

• Use when you need to coordinate multiple front-end, back-end, or QA agents working on the same codebase simultaneously.
• Use when setting up the dual-window workspace (Antigravity IDE + Antigravity 2.0 Agent Manager).
• Use to resolve conflicts or obsolete tutorial steps that mention the integrated "Open Agent Manager" button.

How It Works

Step 1: Parallel Installation

1. Keep your current Antigravity IDE: Do not uninstall the classic IDE (black icon).
2. Download Antigravity 2.0: Fetch the standalone Agent Manager application from the official Antigravity downloads page.
3. Install: Run the installer. It will install alongside your existing IDE without overwriting it. You should now have both:
   • Antigravity IDE (Black Icon) — Your code editor and manual development workspace.
   • Antigravity 2.0 (White Icon) — Your multi-agent orchestrator dashboard.

Step 2: Dual-Workspace Setup

1. Open both the Antigravity IDE and Antigravity 2.0 applications.
2. Load the same project directory (e.g., C:/Users/erwinpzocikk/Dev/GroupProjects/intIntercatedraAdmin) in both apps.
3. In the Agent Manager (white icon), configure your Agent pool. Assign specialized roles (e.g., frontend-agent, backend-agent, qa-validator).

Step 3: Coordinating Agent Execution

1. In the Agent Manager, define the task scopes. To prevent directory conflicts and race conditions:
   • Assign the backend-agent to the server directory (e.g., /server or /api).
   • Assign the frontend-agent to the frontend directory (e.g., /client or /src).
2. Run the agents in parallel.
3. Use the Antigravity IDE (black icon) to monitor file changes in real-time, review diffs, and perform manual tweaks.

Examples

Example 1: Defining Independent Scopes in Multi-Agent Projects

When configuring the Agent Manager dashboard, specify the target files or directories in the prompts to keep agents from colliding:

Backend Agent Task Prompt:

Role: Backend Developer Agent
Workspace Target: /server
Task: Add a new POST /api/v1/students endpoint in server/routes/students.js and update database/models/student.js. Do not edit files outside the /server directory.

Frontend Agent Task Prompt:

Role: Frontend UI Agent
Workspace Target: /client
Task: Build the student registration form under client/components/StudentForm.jsx. Consume the /api/v1/students endpoint. Do not edit files outside the /client directory.

Example 2: Synchronizing Changes via Git

Since agents write code in parallel, sync their work using git in your IDE terminal:

# In the Antigravity IDE terminal, check the changes written by the agents
git status

# Review diffs before committing
git diff

# Commit stable checkpoints so both agents stay in sync with main branch
git add .
git commit -m "feat: synchronize parallel front-end and back-end agent changes"

Best Practices

• ✅ Do: Run both applications simultaneously side-by-side.
• ✅ Do: Enforce strict folder-level boundaries (scopes) for each agent in the Agent Manager.
• ✅ Do: Use git branches or commits to checkpoint progress before letting agents perform massive rewrites.
• ❌ Don't: Let multiple agents edit the same file at the same time, as it causes write conflicts and git merge conflicts.
• ❌ Don't: Search for the "Open Agent Manager" button in the black icon IDE; use the standalone white icon application instead.

Limitations

• This skill assumes you have local administrator permissions to install both applications on Windows/macOS.
• Coordination of file locks relies on standard IDE file-system watchers. If changes do not reflect, reload the IDE workspace (Ctrl+R or developer reload).

Common Pitfalls

• Problem: Agents overwrite each other's code or get stuck in write locks. Solution: Isolate their workspaces. If they must edit the same file, orchestrate them sequentially (e.g., run the backend agent first, commit its changes, then run the frontend agent).
• Problem: Agent Manager changes are not visible in the IDE. Solution: Verify that both applications are pointing to the exact same absolute file path. On Windows, watch out for mapped drives or symlinks.
