Antigravity
gstack 1.91.67.0 adds Antigravity CLI as a host
gstack now installs into Google's Antigravity CLI. Eight contributors sent pull requests asking for it, and this release builds one host from their work. Every skill shows up there as its own gstack command.
Tool names
Skills call Antigravity’s own tools and use the Gemini model profile
run_command · view_file · ask_question · invoke_subagentSkills are written with Antigravity's own tool names, like run_command and view_file, and they use the Gemini model profile. Safety skills only advise there, and Review Army is switched off, the same as on Copilot.
Gemini CLI
Gemini CLI’s skills and settings stay untouched
~/.gemini/skills or Gemini CLI’s settingsGemini CLI shares the same Gemini folder in your home directory, and gstack leaves its skills and its settings alone. A machine with only Gemini CLI installed is never mistaken for Antigravity.
