## Verdicts

**GitHub Copilot CLI.** Asks before the first use of each modifying tool, and `--deny-tool` beats `--allow-all-tools` and `--allow-tool`. Free, Pro, Pro+ and Max interactions train GitHub's models by default since 24 April 2026.

**goose.** Telemetry off until the user opts in, with the collected fields listed. Autonomous mode, which approves every tool call, is the default.

## 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 unless you opt in
3. Turn off model training in Copilot settings on Free, Pro, Pro+ and Max. It's on by default since 24 April 2026
4. Run 1.0.88 or later where enterprise policy matters. Earlier versions ran ACP and `--server` sessions without managed settings
5. Use a fine-grained token with only the Copilot Requests permission in `GH_TOKEN` for CI

### goose

1. Set `GOOSE_MODE=smart_approve` or `approve` before a run. The default approves everything
2. Pass `--max-turns` with a real limit. The default is 1000
3. Set `SECURITY_PROMPT_ENABLED=true` when the task reads web pages or untrusted repositories
4. Use `--output-format json` and `--no-session` in CI, and check the exit code
5. Point remotes and links at aaif-goose/goose and goose-docs.ai. The block/goose paths redirect
