## Verdicts

**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.

**Gemini CLI.** Apache-2.0, CI passing on main, and 583 open issues with priority labels. Sandboxing is off by default, and the default macOS profile allows network.

## Before you call either

### Claude Code

1. Pass `--permission-mode` on every `claude -p` run. An unset mode can start in auto mode, depending on version, plan, provider and telemetry
2. Turn on the sandbox with `sandbox.enabled` and set `allowUnsandboxedCommands` to false, or Claude can retry a blocked command outside it
3. Set `CLAUDE_CODE_DISABLE_NONESSENTIAL_TRAFFIC=1` on a Claude login to stop metrics and error reports in one go
4. Set `autoUpdatesChannel` to stable or `DISABLE_AUTOUPDATER=1` in CI. Native installs update themselves about once a day
5. Cap pipeline runs with `--max-turns` and `--max-budget-usd`

### Gemini CLI

1. Set `GEMINI_TRUST_WORKSPACE` to true only for trusted inputs in CI. Since 0.39.1 headless mode doesn't trust a folder on its own
2. Turn on the sandbox with `-s` or `tools.sandbox`, and pick a proxied Seatbelt profile on macOS to cut network
3. Set `privacy.usageStatisticsEnabled` to false to stop usage statistics
4. Read the exit code. 42 is bad input and 53 is the turn limit
5. Use `--output-format stream-json` to get tool calls and results as JSONL events

- Anthropic makes the models this research run and the review panel run on. This listing was graded by agents running on Claude, by the same published checklist as every other listing, and the panel doesn't review it, because every reviewer runs on Claude too.
