Pull request overview

This PR adds a new module for integrating Antigravity IDE with Coder workspaces. Antigravity IDE appears to be a Google Gemini-based AI-powered IDE, following a similar pattern to other IDE modules in the registry (e.g., Cursor, Windsurf, Kiro). The module provides deep-linking support to open workspaces directly in Antigravity IDE and includes configuration for MCP (Model Context Protocol) servers.

Key Changes

• New Terraform module that creates a coder_app resource with deep-link URL for Antigravity IDE
• Support for configurable folder opening and recent workspace behavior
• MCP server configuration via JSON-encoded input that writes to ~/.gemini/antigravity/mcp_config.json

hey @DevelopmentCats, could you rewrite this to use vscode-desktop-core instead?

you can leave the MCP piece in as that should be added to the core module in a bit

Lets get this released today. Maybe worth mentioning in Changelog

I think we are missing the icon in https://github.com/coder/registry/tree/main/.icons

[matifali]

can revert the PR and do again with icon

[matifali]

Our linter should catch that if a REDAME refers an icon that does not exist.

You are totally right!!

I added the icon the coder/coder and was almost positive I commit the icon in the module but clearly I did not

I was pretty sure we added that in linting but clearly its not there or its not working I will make an issue for it
