Interactions are used to improve Google products unless users opt out, and a headless run exits 0 when a tool is denied.\n\n**GitHub Copilot CLI.** Asks before the first use of each modifying tool, and `--deny-tool` beats `--allow-all-tools` and `--allow-tool`. Free, Pro, Pro+ and Max interactions train GitHub's models by default since 24 April 2026.\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### GitHub Copilot CLI\n\n1. Pass `--deny-tool` for anything destructive. It wins over `--allow-all-tools` and `--allow-tool`\n2. Turn on the sandbox with `/sandbox enable` or `--sandbox`. It's off unless you opt in\n3. Turn off model training in Copilot settings on Free, Pro, Pro+ and Max. It's on by default since 24 April 2026\n4. Run 1.0.88 or later where enterprise policy matters. Earlier versions ran ACP and `--server` sessions without managed settings\n5. Use a fine-grained token with only the Copilot Requests permission in `GH_TOKEN` for CI\n\n## Questions\n\n### Which is better for AI agents, Antigravity CLI or GitHub Copilot CLI?\n\nAntigravity CLI and GitHub Copilot CLI score within a point of each other on agent readiness, 57.7 (C) and 57.6 (C).
