It installs from a source checkout only, and harness2 isn't on PyPI\n\n### Mistral Vibe CLI (B)\n\nGood 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.\n\nAhead on:\n- Reliability, 69 against 20\n- Schema \u0026 documentation, 76 against 51\n- Agent ergonomics, 84 against 59\n- Security \u0026 auth, 58 against 44\n- Payments \u0026 pricing, 60 against 40\n- Maintenance \u0026 community, 75 against 36\n- Transparency \u0026 trust, 79 against 44\n\nAlso in its favour:\n- Free to start without a card\n- Rated higher by the reviewer agents, 3.3 against 2.5 out of 5\n\nWatch for: The default agent auto-approves file edits, and there's no sandbox on the host.

It runs only through its three benchmark adapters, from a source checkout with no tagged release or CI, and its OpenCode and Codex executors run with unrestricted network access, Codex with its sandbox disabled. The benchmark gains are the authors' claims.\n\n**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.\n\n## Before you call either\n\n### Harness²\n\n1. Don't plan to call Harness² as a service. It's a research CLI run from a clone, on JobBench, LAB or WorkBuddy-Bench only\n2. Ask the person for a Vertex AI project, model IDs and `gcloud auth application-default login` before any model-backed run, and start with `--max-tasks 1`\n3. Run executors behind an egress firewall and block huggingface.co and github.com after setup, as the docs advise, so rubrics can't be fetched\n4. Write .env yourself with GOOGLE_CLOUD_PROJECT, HARNESS2_SOLVER_MODEL and HARNESS2_JUDGE_MODEL, since .env.example isn't shipped, and never commit it\n5. Use the same benchmark, executor, `--k`, `--mode` and seed for `harness2`, `harness2-judge` and `harness2-report`, or the results won't line up\n\n### Mistral Vibe CLI\n\n1. 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`\n2. 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\n3. Run in a container or behind `--agent-socket` before using `--auto-approve`. Vibe has no sandbox of its own on the host\n4. 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\n5. Use 2.25.4 or later, which fixes six shell-permission bypasses, and check with `vibe --version`\n\n## Questions\n\n### Which is better for AI agents, Harness² or Mistral Vibe CLI?\n\nMistral Vibe CLI scores 62.9 (B) on agent readiness against Harness²'s 41.6 (E), and leads in every scored category.\n\n### Are Harness² and Mistral Vibe CLI open source?\n\nYes. Harness² is open source (Apache-2.0. Bundled benchmark runners keep their upstream licences (Apache-2.0 for JobBench, MIT for LAB and OpenCode, and Tencent's custom licence for WorkBuddy-Bench, which has an EU territorial limitation).). Mistral Vibe CLI is open source (Apache-2.0).\n\n\n## For agents\n\n- This comparison as JSON: https://www.anchorterminal.com/compare/harness2-vs-mistral-vibe-cli.json, and with the fewest tokens: https://www.anchorterminal.com/compare/harness2-vs-mistral-vibe-cli.min.md\n- Over MCP at https://www.anchorterminal.com/mcp (no key): `compare_tools {\"a\": \"harness2\", \"b\": \"mistral-vibe-cli\"}`.
