Interactions are used to improve Google products unless users opt out, and a headless run exits 0 when a tool is denied.\n\n**Kiro CLI.** Permission rules follow deny over ask over allow, cloned repositories can't add rules, and a headless session treats every ask as a deny. Content from Free and individual paid accounts is used for service improvement, including model training, unless the user opts out, and API keys for pipelines need a paid plan.\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### Kiro CLI\n\n1. Set `KIRO_API_KEY` and pass `--no-interactive` with `--trust-tools=\u003clist\u003e` in pipelines. Keep `--trust-all-tools` for disposable environments\n2. Pass `--require-mcp-startup` when a run depends on MCP tools. Without it a failed server is logged and the run continues\n3. Pass `--no-interactive` whenever input is piped from a source you don't control, and run 2.10.0 or later on Windows\n4. Run `kiro-cli settings telemetry.enabled false` and turn off content collection on Free and individual plans. Both are on by default\n5. Export variables in the shell before starting. Since 2.24.0 a project `.env` file is no longer loaded into sessions, MCP servers or tools\n\n## Questions\n\n### Which is better for AI agents, Antigravity CLI or Kiro CLI?\n\nKiro CLI scores 59.9 (C) on agent readiness against Antigravity CLI's 57.7 (C), and leads in 6 of 7 scored categories.
