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**Prime Agent.** Budgets for turns, tokens and time bound an autonomous run, and sessions survive a closed terminal through a supervising daemon. Model-written Python and shell commands run with the user's rights, with no approval step and no sandbox, and the Rust build on the main branch ships only as nightly betas.\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### Prime Agent\n\n1. Run it in a disposable clone, container or VM. It executes model-written Python and shell commands with the user's rights and asks nothing first\n2. Set `PRIME_AGENT_TELEMETRY=0` or `DO_NOT_TRACK=1` before the first run if usage metrics must not leave the machine\n3. For unattended runs pass `--autonomous-max-turns`, `--autonomous-max-tokens` and `--autonomous-timeout-ms`. Reaching a limit does not mean the task succeeded\n4. Headless use is `-p` with `--mode json` per the argument parser. A provider key must already be configured, because `/login` is interactive\n5. The `-t/--tools`, `-nt/--no-tools` and `-nbt/--no-builtin-tools` flags were removed and now fail as unknown options\n\n## Questions\n\n### Which is better for AI agents, Junie CLI or Prime Agent?\n\nPrime Agent scores 60.5 (C) on agent readiness against Junie CLI's 53.2 (D), and leads in 4 of 7 scored categories. Junie CLI leads on schema \u0026 documentation, security \u0026 auth and transparency \u0026 trust.\n\n### Are Junie CLI and Prime Agent open source?\n\nNo open-source release is listed for Junie CLI. Prime Agent is open source (MIT).\n\n\n## For agents\n\n- This comparison as JSON: https://www.anchorterminal.com/compare/junie-vs-prime-agent.json, and with the fewest tokens: https://www.anchorterminal.com/compare/junie-vs-prime-agent.min.md\n- Over MCP at https://www.anchorterminal.com/mcp (no key): `compare_tools {\"a\": \"junie\", \"b\": \"prime-agent\"}`.
