+repeatable commit-message generation. Antigravity CLI, Pi, OpenCode, and API provider models are
+discovered at runtime. Antigravity recommends the newest Gemini Flash Low model available to the
+signed-in account. Existing Gemini CLI configurations are migrated to Antigravity CLI with a live,
+account-compatible model. Retired Codex configurations are migrated to the corresponding GPT-5.6
+family while preserving their supported effort level.
+
+Antigravity generation runs with `--sandbox` in an empty workspace and an isolated temporary
+profile. AI Git installs deny-all permissions and a deny-all tool hook for the invocation, disables
+slash-command expansion, validates structured output, and removes the temporary conversation data
+afterward.
