## Which one, for what

### 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:
- Security & auth, 58 against 52
- Payments & pricing, 60 against 20

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

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

### Warp (Warp Agent CLI and the Oz Agent API) (C)

Good for: Teams that want one agent across an interactive terminal session and API-started cloud runs, including Claude Code and Codex runs on Warp's infrastructure or their own workers.

Ahead on:
- Reliability, 52 against 37
- Schema & documentation, 89 against 65
- Agent ergonomics, 66 against 58
- Maintenance & community, 84 against 47
- Transparency & trust, 72 against 58

Watch for: The `warp` CLI has no print or headless mode. Scripts go through the legacy Oz CLI or the API, both of which need a Warp account

## Verdicts

**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.

**Warp (Warp Agent CLI and the Oz Agent API).** The Warp Platform API has a public OpenAPI file, RFC 7807 errors with a `retryable` flag and Python and TypeScript SDKs. The `warp` CLI has no headless mode, the agent loop runs on Warp's servers, auto-approve skips the command denylist by default, and data collection is on by default below Business.

## Before you call either

### 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

### Warp (Warp Agent CLI and the Oz Agent API)

1. For unattended work, call `POST https://app.warp.dev/api/v1/agent/runs` with `Authorization: Bearer $WARP_API_KEY`. The `warp` CLI is interactive only
2. Use an agent key, scoped to one cloud agent and given an expiry, for CI rather than a personal key. Keys are created in the Oz web app or the Warp app
3. Set `auto_approve_bypasses_command_denylist = false` under `[agents.warp_agent.other]` before starting `warp --auto-approve`
4. Read `code` and `retryable` in error bodies. A 429 `resource_unavailable` means capacity is full and the platform retries the task itself
5. Pin a version with `WARP_TUI_VERSION` at install, or set `general.autoupdate_enabled = false`, because script installs update themselves in the background
