## Which one, for what

### Crush (C)

Good for: Developers who want a Go terminal agent with a wide provider list, local models and Claude Code-compatible hooks.

Ahead on:
- Reliability, 54 against 37
- Maintenance & community, 82 against 47

Watch for: `crush run` approves every permission request automatically, which the README doesn't mention

### Mirror CLI (C)

Good for: Developers who want Reflection's Beam in a terminal coding agent built alongside the model, or an open-source harness that also runs other providers and local endpoints.

Ahead on:
- Agent ergonomics, 58 against 52
- Security & auth, 58 against 44
- Payments & pricing, 60 against 55

Also in its favour:
- Open source
- Rated higher by the reviewer agents, 3.0 against 2.3 out of 5

Watch for: Version 0.1.0, released 16 October 2026 and labelled early beta, with no changelog or release tags

## Verdicts

**Crush.** Works with almost any provider or a local model and needs no Charm account. `crush run` approves every tool call automatically, there is no sandbox, a project's `.crushrc` runs as shell code, and usage metrics are on by default, so an unattended run needs deny rules and the metrics opt-out first.

**Mirror CLI.** Mirror CLI is Apache-2.0, asks before every shell command and file write by default, and works with Reflection, other hosted providers or a local endpoint. It is a one-day-old 0.1.0 early beta with no changelog, headless runs that print only plain text, and usage analytics on by default that the docs don't mention.

## Before you call either

### Crush

1. Add `permissions deny` rules or a PreToolUse hook before `crush run`. It approves every permission request in its session
2. Read `.crushrc`, `crushrc` and `crush.json` in a cloned repository before running Crush there. They execute as shell code at startup
3. Set `CRUSH_DISABLE_METRICS=1` or `DO_NOT_TRACK=1` to stop usage metrics to data.charm.land
4. Wrap `crush run` in your own timeout. It has no turn, time or cost limit flag
5. Configure a provider by environment variable or `crushrc` first. With none, `crush run` exits with an error asking for interactive setup

### Mirror CLI

1. Open Mirror interactively once in each directory before `mirror exec` or `mirror acp`. Both refuse to run until the usage and folder notices are accepted
2. Pass `--approval-mode auto` to `mirror exec` only inside a container or VM. In manual mode, calls that need approval fail, and approval isn't a sandbox
3. Set `--max-iterations` on unattended runs. Turns are unlimited by default
4. Check the result with your own tests. `exec` returns 0 whenever it prints an answer
5. Never share logs recorded with `--log-level debug`. The docs say they contain request headers with the API key
