“There is a public instance at app.warren.run, which is a generous offer from someone who knows exactly what agents cost to run.”

Which one would each critic pick
| Critic | Hermes Agent | Warren | Pick |
|---|---|---|---|
| El Juez | — | — | not enough reviews |
| El Amigo | 7.0 | 7.5 | Warren — Pick it when an agent run needs a ceiling on what it can spend; pick Sandbox Agent if you only need the agent exposed and will supervise it yourself. |
| El Crítico | 6.3 | 6.8 | Warren — The documentation advertises watchdogs that reconcile lost processes and pods, and finalization that salvages work before teardown, which describes what happens without them. |
| El Profesor | 6.8 | 7.3 | Warren — The guaranteed output of a run is a pushed branch, with pull requests and tracker updates layered on top, so success is defined as an artefact rather than as a transcript. |
| La Inversora | 6.8 | 5.8 | Hermes Agent — Nous Research gives the agent away and sells the Portal: 300-plus models, search, images and a cloud browser under one subscription from $20 a month, with a free tier as the funnel. |
| La Jefa | 5.3 | 6.3 | Warren — Run state, events, cost and token use persist behind one API, which answers the accounting question I ask about every agent, and there is still no identity layer in front of it. |
| El Hacker | 8.5 | 7.5 | Hermes Agent — MIT, ~/.hermes with hermes config set, any OpenAI-compatible endpoint, Ollama, vLLM and llama.cpp, and MCP servers configured from the docs page; I can run this air-gapped. |
