## Which one, for what

### Antigravity CLI (C)

Good for: Developers on Google AI plans or Gemini Enterprise who want a terminal agent with a sandbox on by default and access to several model families, depending on plan.

Ahead on:
- Reliability, 43 against 27
- Schema & documentation, 78 against 39
- Agent ergonomics, 78 against 42
- Security & auth, 53 against 46
- Payments & pricing, 30 against 25
- Maintenance & community, 68 against 62

Also in its favour:
- No incidents deducted, where Cursor CLI loses 5 points for them

Watch for: Closed source. The repository holds the README, changelog and examples, with no source and no licence file

### Cursor CLI (F)

Good for: Teams already on Cursor who want the same agent and rules in a terminal or CI and a hand-off to Cloud Agents.

Ahead on:
- Transparency & trust, 59 against 54

Also in its favour:
- Free to start without a card

Watch for: No CLI changelog, and versions are dates

## Verdicts

**Antigravity CLI.** Google's terminal agent, shipped as a closed-source binary with a terminal sandbox on by default on macOS and Linux and documented headless JSON output. Interactions are used to improve Google products unless users opt out, and a headless run exits 0 when a tool is denied.

**Cursor CLI.** Allow and deny rules for shell, reads, writes, web fetches and MCP tools, with deny taking precedence. No CLI changelog, and versions are dates.

## Before you call either

### Antigravity CLI

1. Read the `status` field from `--output-format json` and read stderr too. A tool refused for lack of approval still exits 0
2. 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
3. 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
4. Turn off Enable Telemetry in the Account settings before running on private repositories if Interactions should not be used for product improvement
5. Set `--print-timeout` explicitly. The docs give a five-minute default, while `agy --help` shows 0s

### Cursor CLI

1. Pass `--trust` in headless runs, or the workspace prompt stops a run with no terminal
2. Write deny rules in .cursor/cli.json before using `--force`. It runs any command they don't match
3. Don't use `--approve-mcps` in repositories you didn't write. Two 2025 CLI advisories came through MCP
4. Set `CURSOR_API_KEY` in CI. `agent login` opens a browser
5. Record `agent --version` with each run. Versions are dates and there's no CLI changelog to compare against
