Antigravity

Vendor: Antigravity Install name: antigravity Status: Preview Native config: ~/.gemini/GEMINI.md plus ~/.gemini/antigravity-cli/plugins/apothem/

Installation

apothem install --harness antigravity

The adapter renders the shared profile to ~/.gemini/GEMINI.md and installs Apothem support cohorts as an Antigravity CLI plugin.

Files written: ~/.gemini/GEMINI.md, ~/.gemini/antigravity-cli/plugins/apothem/plugin.json, ~/.gemini/antigravity-cli/plugins/apothem/skills/, ~/.gemini/antigravity-cli/plugins/apothem/rules/, converted local helper definitions inside the plugin, ~/.gemini/antigravity-cli/plugins/apothem/apothem/templates/, and ~/.gemini/antigravity-cli/plugins/apothem/apothem/hooks/.

Shared user anchor. ~/.gemini/GEMINI.md is also the user-scope anchor for Gemini-family tooling. The Antigravity adapter keeps its extra Apothem material inside the apothem plugin under ~/.gemini/antigravity-cli/plugins/ so it does not claim generic Gemini CLI project directories.

Profile-to-native-config mapping

The adapter reads Apothem's shared profile and renders the instruction anchor plus support cohorts on every apothem install or apothem update run.

Compatibility notes

Preview adapter. The GEMINI.md anchor is active instruction content; the Antigravity plugin preserves converted command skills, reusable skills, local helper definitions, rules, templates, and hook support material in a clear Apothem-owned namespace. Hook files are not registered as active Antigravity hook events until the adapter owns a schema translation layer for Antigravity hooks.json.

Verification

apothem verify --harness antigravity

The verify command confirms that:

1. The native context file exists at the expected path.
2. The Apothem Antigravity CLI plugin metadata exists and declares the apothem plugin name.

Updating

apothem update --harness antigravity

Re-derives the native config from the current shared profile state. Run after editing ~/.config/apothem/profile.yaml or upgrading the installed Apothem package.

Uninstalling

apothem uninstall --harness antigravity

Removes the native config files written by the adapter. The shared profile YAML and Apothem engine are unaffected.

Conformity gate

python -m apothem.conformity.gate --all .
