Autonomous mode, which approves every tool call, is the default.\n\n**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.\n\n## Before you call either\n\n### goose\n\n1. Set `GOOSE_MODE=smart_approve` or `approve` before a run. The default approves everything, and the first-run prompt preselects Auto\n2. Pass `--max-turns` with a real limit. The default is 1000\n3. Set `SECURITY_PROMPT_ENABLED=true` when the task reads web pages or untrusted repositories\n4. Use `--output-format json` and `--no-session` in CI, and check the exit code\n5. Point remotes and links at aaif-goose/goose and goose-docs.ai. The block/goose paths redirect\n\n### Mirror CLI\n\n1. 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\n2. 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\n3. Set `--max-iterations` on unattended runs. Turns are unlimited by default\n4. Check the result with your own tests. `exec` returns 0 whenever it prints an answer\n5. Never share logs recorded with `--log-level debug`. The docs say they contain request headers with the API key\n\n## Questions\n\n### Which is better for AI agents, goose or Mirror CLI?\n\ngoose scores 73.9 (BB) on agent readiness against Mirror CLI's 54.2 (C), and leads in 6 of 7 scored categories.\n\n### Are goose and Mirror CLI open source?\n\nYes. goose is open source (Apache-2.0). Mirror CLI is open source (Apache-2.0).\n\n\n## For agents\n\n- This comparison as JSON: https://www.anchorterminal.com/compare/goose-vs-reflection-mirror.json, and with the fewest tokens: https://www.anchorterminal.com/compare/goose-vs-reflection-mirror.min.md\n- Over MCP at https://www.anchorterminal.com/mcp (no key): `compare_tools {\"a\": \"goose\", \"b\": \"reflection-mirror\"}`.
