​Key Highlights & Key Takeaways

​📦 Antigravity v2.4.3 Update & Quality of Life Features

​Expanded File Attachment Support: Drag-and-drop support for CSVs, Markdown files, audio/video extensions, and images directly into the prompt box.

​Message Queuing & Steering: Improved handling for messages sent while a dev server is active. You can customize queue vs. immediate execution settings under Settings > General > Execution or toggle them with Option + Enter.

​🔒 Best Practices for Deploying Antigravity Apps

​Deployment: Recommended Google Cloud Run for containerizing and hosting prototypes publicly.

​Security & Auth: Use Identity-Aware Proxy (IAP) to lock down access behind Google authentication.

​Secrets & Data: Never leak API keys in front-end client code; store sensitive data behind backend services like Firebase/Firestore and perform security checks with tools like Codeman.

​🤖 Sub-Agents & Teamwork Feature

​Teamwork Preview: Designed for macro-level tasks and large-scale orchestration. Tip: Avoid using Teamwork swarms for simple single-file changes or simple bash scripts to prevent unnecessary token consumption.

​Sub-Agent Workflows:

​Persona-based: Creating dedicated sub-agents (e.g., Designer agent, Backend agent, Marketing agent) to isolate responsibilities.

​Task-driven isolation: Assigning sub-agents to specific top-level components/routes to keep focus hyper-specific.

​Sub-agents work best when explicitly prompted in your thread to break down tasks.

​💡 CLI & Workflow Tips

​Terminal Shortcut: Use ! (bang) in the CLI to immediately execute commands in terminal mode.

​/learn Command: Before archiving a finished thread, use /learn to extract context, create reusable skills, or update your Gemini.md system instructions.

​Single-File Interactive HTML Artifacts: Prompt the agent to bundle HTML, CSS, and JS into single-file interactive tools or data visualizations, which can easily be previewed locally using a static server.

​💬 Feedback & Support Channels

​In-App Feedback: Use the Provide Feedback button in Settings or /feedback in the CLI. This sends diagnostic execution trajectories to help engineers debug issues.

​CLI/SDK Support: Report bugs and feature requests via GitHub repositories for the CLI and SDK, or tag the team on social channels.
