## Which one, for what

### 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:
- Security & auth, 69 against 57
- Transparency & trust, 69 against 61

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

### MiniMax Code (B)

Good for: Scripted coding runs on MiniMax's models or any compatible model, driven by JSON output and exit codes.

Ahead on:
- Reliability, 63 against 57
- Agent ergonomics, 75 against 67
- Payments & pricing, 60 against 40

Also in its favour:
- Open source
- Rated higher by the reviewer agents, 3.5 against 2.8 out of 5
- No incidents deducted, where Kiro CLI loses 4 points for them

Watch for: Pre-1.0 and labelled a source preview, with npm at 0.6.12 and the public source at 0.6.5

## Verdicts

**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.

**MiniMax Code.** An MIT-licensed terminal coding agent with a headless mode that returns versioned JSON, documented exit codes and an ACP server, and telemetry off by default. It's pre-1.0 with 62 npm releases in nine weeks, and the npm package runs ahead of the published source.

## Before you call either

### 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. Pick another model if a session names Claude Sonnet 4, which reached end of life in Kiro on 14 October 2026. Kiro doesn't switch it for you

### MiniMax Code

1. Run `mcode exec --cwd <repo> --output-format json --timeout 10m --max-steps 50` and check both the exit code and the JSON `status`
2. Keep `--permission full` and `off` for a container or throwaway workspace. The default `smart` fails when it would need a person
3. Set `MCODE_PROVIDER_API_KEY` and add a provider for BYOK. M Plan models need a browser sign-in with `mcode login --region global`
4. Set `MINIMAX_DATA_DIR` per CI runner. Keys and sessions live in `~/.minimax` by default
5. Pin a version. npm published 62 releases in nine weeks and the public source trails it
