Interactions are used to improve Google products unless users opt out, and a headless run exits 0 when a tool is denied.\n\n**Claude Code.** Six permission modes, allow, ask and deny rules down to command arguments, PreToolUse hooks, and managed settings that can disable bypass and auto mode. The sandbox is off by default and native Windows has none.\n\n## Before you call either\n\n### Antigravity CLI\n\n1. Read the `status` field from `--output-format json` and read stderr too. A tool refused for lack of approval still exits 0\n2. Pre-approve each shell command and tool a headless run needs with `action(target)` rules under `permissions.allow` in ~/.gemini/antigravity-cli/settings.json, because headless runs cannot ask\n3. Export `GEMINI_API_KEY` after setting modelProvider to gemini. The CLI won't start when the key is missing, and setting the variable alone has no effect\n4. Turn off Enable Telemetry in the Account settings before running on private repositories if Interactions should not be used for product improvement\n5. Set `--print-timeout` explicitly. The docs give a five-minute default, while `agy --help` shows 0s\n\n### Claude Code\n\n1. Pass `--permission-mode` on every `claude -p` run. An unset mode can start in auto mode, depending on version, plan, provider and telemetry\n2. Turn on the sandbox with `sandbox.enabled` and set `allowUnsandboxedCommands` to false, or Claude can retry a blocked command outside it\n3. Set `CLAUDE_CODE_DISABLE_NONESSENTIAL_TRAFFIC=1` on a Claude login to stop metrics and error reports in one go\n4. Set `autoUpdatesChannel` to stable or `DISABLE_AUTOUPDATER=1` in CI. Native installs update themselves about once a day\n5. Cap pipeline runs with `--max-turns` and `--max-budget-usd`\n\n## Questions\n\n### Which is better for AI agents, Antigravity CLI or Claude Code?\n\nClaude Code scores 61.9 (C) on agent readiness against Antigravity CLI's 57.7 (C), and leads in 6 of 7 scored categories.
