Install Node.js first, then open your terminal and run:
npx get-shit-done-cc@latest--antigravity--global
For only the current project:
npx get-shit-done-cc@latest--antigravity--local
Then open/reload Antigravity and verify:
/gsd-help
The official GSD repository currently documents these exact Antigravity installation commands.
So your Reel should NOT say:
"GSD isn't available in Antigravity."
Instead say:
"GSD isn't a normal Antigravity plugin — it's a repo-based workflow that you install directly into Antigravity."
That's much more accurate.
Roo Code is primarily a VS Code extension, so the approach is different from GSD. Its official installation documentation supports installing the extension through the VS Code Marketplace or manually through a VSIX.
