Help​

You can ask me general programming questions, or chat with the following participants which have specialized expertise and can perform actions:

  • @workspace - Ask about your workspace
    • /explain - Explain how the code in your active editor works
    • /tests - Generate unit tests for the selected code
    • /fix - Propose a fix for the problems in the selected code
    • /new - Scaffold code for a new file or project in a workspace
    • /newNotebook - Create a new Jupyter Notebook
    • /fixTestFailure - Propose a fix for the failing test
    • /setupTests - Set up tests in your project (Experimental)
  • @vscode - Ask questions about VS Code
    • /search - Generate query parameters for workspace search
    • /startDebugging - Generate launch config and start debugging in VS Code (Experimental)
  • @terminal - Ask how to do something in the terminal
    • /explain - Explain something in the terminal
  • @github - Get answers grounded in web search, code search, and your enterprise's knowledge bases

You can also help me understand your question by using the following variables to give me extra context:

  • #editor - The visible source code in the active editor
  • #selection - The current selection in the active editor
  • #terminalLastCommand - The active terminal's last run command
  • #terminalSelection - The active terminal's selection
  • #file - Choose a file in the workspace

To have a great conversation, ask me questions as if I was a real programmer:

  • Show me the code you want to talk about by having the files open and selecting the most important lines.
  • Make refinements by asking me follow-up questions, adding clarifications, providing errors, etc.
  • Review my suggested code and tell me about issues or improvements, so I can iterate on it.

You can also ask me questions about your editor selection by starting an inline chat session (⌘I).

Comparisons​

  • Claude Opus 4.5: First model to break 80% on SWE-bench. 67% cheaper than before. Best for backend development and complex refactoring. 9.5/10.
  • Gemini 3: 1 million token context window, 1501 Elo score. Better at frontend and creative work than Opus. Accessible across the Gemini Products. 8.5/10.
  • Nano Banana Pro: Google’s image generator that finally works. 4K output, handles 5 people consistently, integrates everywhere. 8/10.
  • Antigravity: Google’s new IDE. Buggy, crashes often, not ready. 6.5/10. Stick with Cursor or Windsurf / Claude Code or Faactory.ai for now.
  • What I actually use: Gemini 3 for frontend, Opus 4.5 for backend, Factory.ai or Claude Code for serious coding work.
