Watch for
Autonomous mode, which approves every tool call, is the default
Best 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
- Transparency & trust, 79 against 63
Also in its favour

Verdicts
goose
Telemetry off until the user opts in, with the collected fields listed. Autonomous mode, which approves every tool call, is the default.
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
goose
- Set
GOOSE_MODE=smart_approveorapprovebefore a run. The default approves everything, and the first-run prompt preselects Auto - Pass
--max-turnswith a real limit. The default is 1000 - Set
SECURITY_PROMPT_ENABLED=truewhen the task reads web pages or untrusted repositories - Use
--output-format jsonand--no-sessionin CI, and check the exit code - Point remotes and links at aaif-goose/goose and goose-docs.ai. The block/goose paths redirect
Mistral Vibe CLI
- Pass
--agenton every-prun (planis read-only). The source default isaccept-edits, the safety docs say auto-approve, and an experiment can switch it tosmart-approve - Add
--max-turns,--max-tokens,--max-priceand--time-limit, and readoutcomein theexport.jsonthat--output-dirwrites. Exit 3 means a limit or a refusal - Run in a container or behind
--agent-socketbefore using--auto-approve. Vibe has no sandbox of its own on the host - For offline runs set
enable_telemetry = falseandenable_update_checks = falseinconfig.toml. The docs'enable_auto_updateisn't the key the code reads - Use 2.25.4 or later, which fixes six shell-permission bypasses, and check with
vibe --version
