Which is a bit odd given that Claude code extension in VSCode is by far the best agent integration into a codebase that I know of.

The Claude Code extension on VS Code does very little (too little in my opinion). The integration level with agentic functionality provided by Antigravity goes much deeper in my 20 minutes or so of playing with it. The biggest value pieces I see is: Agent Manager window which provides a unified view of all my agents running across all my workspaces (!) where I can quickly approve or respond to followup questions and quickly brings me to the code in context for each agent, additionally, I can select a piece of code and comment on it inline and that comment gets sent to the correct, active agent. These two things alone are items which I have been looking for... Too bad I only have approval to use Claude Code at work. This looks promising.

I don't even know what the Claude Code extension does in vscode. I have it installed but hell if I know what it's doing. I run Claude in one of vscode's terminals, and do everything through there. I do see (sometimes) diffs pop up in the IDE, I guess that's the extent of this integration.
