Which one would each critic pick
| Critic | Deep Agents | NVIDIA NeMo Agent Toolkit | Pick |
|---|---|---|---|
| El Juez | — | — | not enough reviews |
| El Amigo | 8.0 | 7.3 | Deep Agents — Pick this when you want a working agent today and the freedom to replace one piece later; pick a smaller library if you would rather understand every line first. |
| El Crítico | 6.8 | 6.5 | Deep Agents — Shell access runs in a sandbox of your choosing and the documentation names no container runtime, so the isolation is a backend you must supply and can forget to. |
| El Profesor | 8.0 | 7.5 | Deep Agents — Context management is explicit: long threads are summarised and tool output is offloaded to disk rather than carried, which treats the window as a budget instead of a container. |
| La Inversora | 8.0 | 8.0 | no preference |
| La Jefa | 6.8 | 8.0 | NVIDIA NeMo Agent Toolkit — No licence cost for sixty engineers, it runs unattended in our pipelines, and the tracing path is a third-party service my data protection officer will ask about. |
| El Hacker | 8.8 | 7.0 | Deep Agents — MIT, `uv add deepagents`, any MCP server becomes a tool, and it is model-agnostic down to open-weight models on my own machine. |
