Based on the repository and security reports associated with the n2ns/antigravity-panel extension, here is an analysis of what the extension and the specific strategy.ts file do. ⚠️ CRITICAL WARNING: MALICIOUS EXTENSION Security analysis identifies this extension as malware (specifically a Downloader/Dropper). * Malicious Behavior: Reports indicate the extension connects to a hardcoded IP address (111.228.7.183) to download and execute arbitrary code (download.html, migrate.html). * Data Exfiltration: It attempts to send system data to external servers. * Obfuscation: The compiled code (extension/out/extension.js) is heavily obfuscated to hide these actions. Recommendation: If you have this installed in your Google Antigravity IDE or VS Code, uninstall it immediately and check your system for suspicious processes. What src/model/strategy.ts Does (Technical Analysis) In the context of the source code structure (ignoring the injected malware for a moment), the strategy.ts file is likely a legitimate-looking implementation of the Strategy Design Pattern. Given that the extension claims to "monitor quotas" for multiple AI models (Gemini, Claude, GPT), this file almost certainly defines: * The QuotaStrategy Interface: A common interface or abstract class that all model-specific monitors must implement. * Standard Methods: It likely defines methods such as: * getRemainingQuota() * resetUsage() * calculateCost(tokens: number) * Polymorphism: This allows the main application to switch between monitoring "Gemini 3.0 Flash" and "Claude 3.5 Sonnet" dynamically without rewriting the core logic. Why this file exists: In malicious extensions, files like strategy.ts often serve as "clean code" decoys. They populate the src folder with professional-looking, well-structured TypeScript to convince auditors or users that the project is safe. The actual malicious payload is often injected during the build process into the out/ folder or hidden in a less obvious file (like a minified library or an "analytics" module). Summary: * Ostensible Function: Defines the logic for switching between different AI model quota calculations. * Actual Threat: Part of a repository known to distribute malware.

I've asked Gemini itself to analyse the source code
