Use Image from Clipboard

Overview

Antigravity CLI does not support direct image paste (the Alt+V shortcut available in Claude Code and Codex CLI). This skill is the workaround: it reads an image from the Windows clipboard via .NET System.Windows.Forms and saves it as a PNG to a temp path, emitting the file path so Antigravity can pick it up with its image-viewing tool.

When to Use

Use this skill when:

• You want to share a screenshot or clipboard image with Antigravity and it cannot accept it via direct paste
• You need to materialise clipboard image data as a file path for further analysis or upload
• Running any PowerShell workflow that needs clipboard image access on Windows

Not for: macOS/Linux, non-image clipboard content (text, files), or Claude Code/Codex sessions where Alt+V paste works natively.

The Problem This Solves

CLI	Native image paste	This skill needed?
Claude Code	✅ Alt+V	No
Codex CLI	✅ Alt+V	No
Antigravity CLI	❌ Not supported	Yes

Workflow

1. Take a screenshot or copy any image to the clipboard (Print Screen, Snipping Tool, Win+Shift+S, etc.)
2. Run the script below in PowerShell — it outputs a file path
3. Pass that path to Antigravity using its view_file tool on the returned path

Script

Add-Type -AssemblyName System.Windows.Forms
if ([System.Windows.Forms.Clipboard]::ContainsImage()) {
    $img = [System.Windows.Forms.Clipboard]::GetImage()
    $tempPath = [System.IO.Path]::Combine($env:TEMP, "cli_screenshot.png")
    $img.Save($tempPath, [System.Drawing.Imaging.ImageFormat]::Png)
    Write-Output $tempPath
} else {
    Write-Error "No image in clipboard."
}

Alternatively, run it inline from a one-liner:

powershell -Command "Add-Type -AssemblyName System.Windows.Forms; if ([System.Windows.Forms.Clipboard]::ContainsImage()) { $img = [System.Windows.Forms.Clipboard]::GetImage(); $p = [System.IO.Path]::Combine($env:TEMP, 'cli_screenshot.png'); $img.Save($p, [System.Drawing.Imaging.ImageFormat]::Png); Write-Output $p } else { Write-Error 'No image in clipboard.' }"

Quick Reference

Detail	Value
Output	Absolute path to saved PNG (stdout)
Error path	Write-Error if clipboard has no image
Output filename	cli_screenshot.png (fixed; overwritten each call)
Requires	Windows, PowerShell 5.1+, .NET Framework (built-in on all modern Windows)
Assembly loaded	System.Windows.Forms
Typical save location	C:\Users\<you>\AppData\Local\Temp\cli_screenshot.png

Common Mistakes

Mistake	Fix
Running on macOS/Linux	Use platform-specific clipboard tools; this is Windows-only
Running when no image is in clipboard	ContainsImage() guards against crashes — copy an image first
Expecting unique filenames per call	The path is always cli_screenshot.png; rename/copy after if you need multiple
Piping the error output	Write-Error writes to PowerShell's error stream, not stdout; check $? or wrap in try/catch
Trying Alt+V in Antigravity	Not supported — use this script instead

Integration Example

After running the script and getting back a path like C:\Users\you\AppData\Local\Temp\cli_screenshot.png, tell Antigravity:

"Please view the image at C:\Users\you\AppData\Local\Temp\cli_screenshot.png"

Antigravity will use its view_file tool to load and analyse the image.
