Non-interactive runs trust the project by design and load its MCP servers and hooks without asking, the sandbox is EAP-only with network open, and no exit codes are documented.\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### Junie CLI\n\n1. Run headless only in repositories you trust. One-shot and piped runs load the project's MCP servers, hooks and skills without asking\n2. Set `JUNIE_API_KEY` (from junie.jetbrains.com/cli) or a provider key such as `JUNIE_ANTHROPIC_API_KEY` in CI. The default sign-in opens a browser\n3. Add `--output-format json` or `--json-output-file` to parse results. Check the output, since exit codes aren't documented\n4. Pass `--share-anonymous-statistics false` if no usage statistics may leave the runner\n5. Pin a build with `--use-version` and `--skip-update-check`. The CLI updates itself on start by default\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, Junie CLI or Mirror CLI?\n\nMirror CLI scores 54.2 (C) on agent readiness against Junie CLI's 53.2 (D), and leads in 4 of 7 scored categories. Junie CLI leads on reliability, maintenance \u0026 community and transparency \u0026 trust.\n\n### Are Junie CLI and Mirror CLI open source?\n\nNo open-source release is listed for Junie CLI. Mirror CLI is open source (Apache-2.0).\n\n\n## For agents\n\n- This comparison as JSON: https://www.anchorterminal.com/compare/junie-vs-reflection-mirror.json, and with the fewest tokens: https://www.anchorterminal.com/compare/junie-vs-reflection-mirror.min.md\n- Over MCP at https://www.anchorterminal.com/mcp (no key): `compare_tools {\"a\": \"junie\", \"b\": \"reflection-mirror\"}`.
