Adds Google's Antigravity CLI as an experimental host through defineHost(): skills in ~/.gemini/antigravity-cli/skills/gstack-*, a runtime root with .source-path for /gstack-upgrade, names equal to their gstack-<skill> directories, name+description frontmatter with the 1024-char limit, the Gemini overlay, and a preamble glossary mapping Claude tool names to Antigravity's documented tools (run_command, view_file, write_to_file, replace_file_content, grep_search, find_by_name, invoke_subagent, ask_question). Setup: ./setup --host agy (alias antigravity), --host auto on the agy binary or ~/.gemini/antigravity-cli, never a Gemini-CLI-only ~/.gemini. Registry tier, --status known roots, uninstall and team-init cover it. Gemini CLI's ~/.gemini/skills and settings are never touched.

Adds Antigravity CLI as a gstack host. Garry approved it in the Oct 8 triage, after eight contributors sent PRs for it. This is one host on the current host-config system, built on those PRs with credit. Paths and tool names were checked against Google's Antigravity docs on 2026-10-08.
What it does
agy, withantigravityas an alias in setup and gen-skill-docs.antigravityas the primary name made the per-fence runtime prelude 408 bytes, over its 400-byte budget.agyit is exactly 400, so the budget did not need to rise.~/.gemini/antigravity-cli/skills/gstack-*, the CLI's own global skills directory per antigravity.google/docs/skills.~/.gemini/config/skills/. The docs list that path only for the Antigravity 2.0 app and the IDE, so this host doesn't cover them yet..../skills/gstack, with.source-pathfor/gstack-upgrade.nameanddescription. The build fails if a description exceeds 1,024 characters./gstack-review), so built-in commands can't shadow them.ask_question, Bash→run_command, Read→view_file, Write→write_to_file, Edit→replace_file_content, Grep→grep_search, Glob→find_by_name, Agent→invoke_subagent.CLAUDE.mdtoAGENTS.md.--host agyor--host antigravity.--host autotriggers whenagyis on PATH or~/.gemini/antigravity-cliexists; a bare~/.gemininever triggers it..gstack-installed-hosts, so the render-only-installed-hosts change from v1.91.65.0 keeps its render.--status, uninstall (with the same ownership check as Copilot) and team-init all cover it.
