Overview

This skill provides unified access to two distinct terminal bridge servers:

Server 1: AGS PowerShell Bridge (Google Antigravity)

• Purpose: Execute commands via HTTP from Claude/MCP to a local PowerShell process
• Port: 8765 (configurable)
• Config: CAPABILITY/MCP/powershell_bridge_config.json
• Script: CAPABILITY/MCP/powershell_bridge.ps1
• Use Case: Google Antigravity MCP tool terminal_bridge

Server 2: VSCode Antigravity Bridge

• Purpose: Spawn named terminals inside VSCode IDE
• Port: 4000 (default)
• Extension: antigravity-bridge VSCode extension
• Use Case: Creating agent terminals that appear in VSCode panel

Trigger

Use when:

• Setting up terminal bridges for agent command execution
• Launching terminals inside VSCode
• Executing commands via the PowerShell HTTP bridge
• Checking bridge server status

Server Details

AGS PowerShell Bridge (Port 8765)

Used by Google Antigravity and the MCP terminal_bridge tool.

Setup:

powershell -ExecutionPolicy Bypass -File CAPABILITY\MCP\powershell_bridge.ps1

API:

POST http://127.0.0.1:8765/run
Headers: X-Bridge-Token: <token>
Body: {"command": "dir", "cwd": "C:\\path"}

VSCode Antigravity Bridge (Port 4000)

Used by agents to spawn terminals inside VSCode.

Setup:

1. Install VSCode extension: antigravity-bridge-0.1.0.vsix
2. Extension auto-starts HTTP server on port 4000

API:

POST http://127.0.0.1:4000/terminal
Body: {"name": "Terminal Name", "cwd": "/path", "initialCommand": "echo hello"}

Constraints

• INV-014: External window spawning is PROHIBITED. Use VSCode bridge for agent terminals.
• AGS bridge requires valid token from config file.
• VSCode bridge only works when VSCode is running with extension installed.

Fixtures

• fixtures/basic/ - Basic status check test
