“It cleans up shell sessions orphaned by a cancelled turn, a feature that exists because somebody found out the hard way.”

Which one would each critic pick
| Critic | Nanocodex | smolagents | Pick |
|---|---|---|---|
| El Juez | — | — | not enough reviews |
| El Amigo | 7.3 | 7.0 | Nanocodex — Pick it when you are shipping a product with a coding agent inside it; pick Sandbox Agent when you would rather talk to the agent over HTTP than link it. |
| El Crítico | 6.5 | 6.3 | Nanocodex — It supports one OpenAI stack deliberately and is not a provider abstraction, so the day a second model vendor matters you write the abstraction it refused to write. |
| El Profesor | 7.3 | 6.3 | Nanocodex — Turn state, compaction, steering and reconnect replay live in a machine separate from transport, so partial responses and cancelled turns have defined behaviour. |
| La Inversora | 6.3 | 6.5 | smolagents — Hugging Face gives the library away because the default model class calls its Inference providers; the framework is a funnel to a marketplace, which is a durable reason to keep maintaining it. |
| La Jefa | 6.0 | 6.3 | smolagents — As a dependency it costs nothing, has no support contract, and ships Hub integration that lets an engineer publish an agent as a public Space, which is the governance conversation to have first. |
| El Hacker | 7.8 | 8.0 | smolagents — Apache-2.0, TransformersModel loads weights on my own GPU, Ollama works, ToolCollection.from_mcp pulls any MCP server, and Tool.from_langchain steals from the other ecosystem. |
