antigravity-multi-reviewlisted

# Antigravity Multi Review Use this skill when Codex needs several independent Antigravity review passes with different role directives. Run: ```bash node "${CODEX_PLUGIN_ROOT}/scripts/antigravity-companion.mjs" multi-review "$ARGUMENTS" ``` ## Natural-Language Model Routing Codex should let the user ask for Antigravity multi-role review in normal language. Do not ask the user to write `--model-provider` or `--model` unless troubleshooting the plugin itself. When converting the user's request to companion invocation: - Default to the Gemini provider by omitting provider overrides and relying on the runtime default when no provider is explicit. - Use the Claude provider only when the user explicitly asks for Claude through Antigravity, for example "use Antigravity's Claude model" or "Claude via Antigravity"; pass explicit `--model-provider claude` argv tokens or set `ANTIGRAVITY_FOR_CODEX_MODEL_PROVIDER=claude`. - Provider selection is explicit: strict, deep, high-confidence, advanced, or multi-agent language does not switch providers. Keep Gemini unless Claude is explicit. - If the user names a concrete Gemini model, keep or choose the Gemini provider and pass the model as explicit `--model` argv tokens or `ANTIGRAVITY_FOR_CODEX_MODEL`. - If the user names a concrete Claude/Sonnet/Opus model through Antigravity, choose the Claude provider and pass the model as explicit `--model` argv tokens or `ANTIGRAVITY_FOR_CODEX_MODEL`. - Do not concatenate provider/model flags into
