## Which one, for what

### Claude Code (C)

Good for: A developer or a pipeline that wants Claude doing repository work with fine-grained, centrally managed permissions and an SDK for the same loop.

Ahead on:
- Agent ergonomics, 87 against 67
- Security & auth, 80 against 66
- Maintenance & community, 82 against 73
- Transparency & trust, 81 against 67

Watch for: The sandbox is off by default and native Windows has none

### Kiro CLI (C)

Good for: Teams on AWS that want one agent configuration across terminal, IDE and web, with central permission policy, prompt logging to their own S3 bucket and IAM Identity Centre sign-in.

Ahead on:
- Reliability, 57 against 50
- Payments & pricing, 40 against 20

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

Watch for: Free and individual paid accounts have content used for service improvement, including model training, unless they opt out

## 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.

**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.

## 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`

### Kiro CLI

1. Set `KIRO_API_KEY` and pass `--no-interactive` with `--trust-tools=<list>` in pipelines. Keep `--trust-all-tools` for disposable environments
2. Pass `--require-mcp-startup` when a run depends on MCP tools. Without it a failed server is logged and the run continues
3. Pass `--no-interactive` whenever input is piped from a source you don't control, and run 2.10.0 or later on Windows
4. Run `kiro-cli settings telemetry.enabled false` and turn off content collection on Free and individual plans. Both are on by default
5. 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
