## Which one, for what

### GitHub Copilot CLI (C)

Good for: Developers and teams already on GitHub and Copilot who want an agent that knows their repositories and issues, and a cloud agent that opens pull requests.

Ahead on:
- Security & auth, 63 against 58

Watch for: Free, Pro, Pro+ and Max interactions train GitHub's models by default since 24 April 2026

### Mistral Vibe CLI (B)

Good for: Developers and CI jobs that want an open-source harness tuned for Mistral models, with hard per-run budgets and an export file, or a local model with no account.

Ahead on:
- Reliability, 69 against 55
- Agent ergonomics, 84 against 72
- Payments & pricing, 60 against 40
- Transparency & trust, 79 against 70

Also in its favour:
- Open source
- Rated higher by the reviewer agents, 3.3 against 2.5 out of 5

Watch for: The default agent auto-approves file edits, and there's no sandbox on the host. Isolation needs the experimental `--agent-socket` server or a container

## Verdicts

**GitHub Copilot CLI.** Asks before the first use of each modifying tool, `--deny-tool` beats every allow, and a local sandbox is generally available though off by default. Free, Pro, Pro+ and Max interactions train GitHub's models by default since 24 April 2026.

**Mistral Vibe CLI.** Apache-2.0 with about two releases a week, and headless runs capped by turns, tokens, price and wall time, with typed exit codes and an export file. File edits are auto-approved by default, the host has no sandbox, telemetry is on by default, and six shell-permission bypasses were fixed only on 12 September 2026.

## Before you call either

### GitHub Copilot CLI

1. Pass `--deny-tool` for anything destructive. It wins over `--allow-all-tools` and `--allow-tool`
2. Turn on the sandbox with `/sandbox enable` or `--sandbox`. It's off by default
3. Turn off model training in Copilot settings on Free, Pro, Pro+ and Max. It's on by default since 24 April 2026
4. Move off Claude Opus 4.8, Claude Opus 5 and GPT-5.6 Terra before 16 November 2026
5. Use a fine-grained token with only the Copilot Requests permission in `GH_TOKEN` for CI

### Mistral Vibe CLI

1. Pass `--agent` on every `-p` run (`plan` is read-only). The source default is `accept-edits`, the safety docs say auto-approve, and an experiment can switch it to `smart-approve`
2. Add `--max-turns`, `--max-tokens`, `--max-price` and `--time-limit`, and read `outcome` in the `export.json` that `--output-dir` writes. Exit 3 means a limit or a refusal
3. Run in a container or behind `--agent-socket` before using `--auto-approve`. Vibe has no sandbox of its own on the host
4. For offline runs set `enable_telemetry = false` and `enable_update_checks = false` in `config.toml`. The docs' `enable_auto_update` isn't the key the code reads
5. Use 2.25.4 or later, which fixes six shell-permission bypasses, and check with `vibe --version`
