## Which one, for what

### mini-swe-agent (C)

Good for: Benchmark runs, research baselines and RL or fine-tuning pipelines that want a minimal, readable agent with a linear trajectory, and for people who want to read every line of their harness.

Ahead on:
- Reliability, 70 against 60
- Payments & pricing, 60 against 50

Also in its favour:
- No key needed to call it

Watch for: The default local environment runs commands on the host with no isolation and the full host environment

### 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 58
- Agent ergonomics, 77 against 69
- Maintenance & community, 74 against 49

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

**mini-swe-agent.** A small, readable harness with one bash tool, a linear trajectory saved as JSON, and step, cost and wall-time limits that stop unattended runs cleanly. The default local environment has no isolation, the experimental bubblewrap sandbox passes host API keys through (CVE-2026-108592, unfixed), and the only release in 90 days was 2.4.6 on 23 July 2026.

**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

### mini-swe-agent

1. Run with `-y --exit-immediately` for unattended use. Without `--exit-immediately` it waits for input when the agent finishes
2. Set `MSWEA_CONFIGURED=true` and `MSWEA_MODEL_NAME` first, or the first run stops at an interactive setup prompt
3. Read `info.exit_status` in the `-o` trajectory file. A run that hits its limits still exits normally
4. For untrusted repositories use `-c mini.yaml -c environment.environment_class=docker -c environment.image=<image>`. The local and bubblewrap environments both expose host variables
5. Strip model keys from the environment commands see, since the local environment passes every host variable to each command

### 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
