## Which one, for what

### 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:
- Payments & pricing, 60 against 50

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

### OpenMausBot (B)

Good for: A person or an outside agent who wants several CLI agents (Claude Code, Codex, Grok, ACP CLIs) organised as named bots with their own computers, routines and approvals, driven by MCP or a CLI.

Ahead on:
- Schema & documentation, 90 against 81

Also in its favour:
- Runs on your own machine

Watch for: New bots start at Full access, which approves provider permission requests without a card

## Verdicts

**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.

**OpenMausBot.** A bounded 20-tool MCP server with typed schemas, annotations and idempotent sends, and a headless CLI with JSON output and exit codes, let another agent hand work to a bot team and wait on it. New bots start at Full access, so provider permission requests pass without a card, and usage analytics stay on until switched off.

## Before you call either

### 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

### OpenMausBot

1. Ask the owner for a pairing code from Settings > Phone, exchange it at `POST /api/auth/pair`, and set `OPENMAUSBOT_TOKEN` with an explicit `OMB_PORT`
2. Pass a `send_id` with every `send_bot_message` and `send_channel_message`, so a retry returns the first receipt
3. Use `wait_for_conversation` instead of polling, and on `needs-user` stop and tell the owner a card is waiting
4. Check a bot's access level with the owner before sending work. New bots run at Full access unless defaults were changed
5. Ask the owner to switch off Settings > General > Usage analytics if nothing beyond model calls should leave the machine

## Questions

### Which is better for AI agents, MiniMax Code or OpenMausBot?
