Which one would each critic pick
| Critic | Kimi Agent SDK | smolagents | Pick |
|---|---|---|---|
| El Juez | — | — | not enough reviews |
| El Amigo | 7.0 | 7.0 | no preference |
| El Crítico | 6.5 | 6.3 | Kimi Agent SDK — One model, no substitution: the row records the backbone as a single vendor's and bring-your-own-model as unavailable, so every line you write here is written against one company. |
| El Profesor | 7.3 | 6.3 | Kimi Agent SDK — Permission requests are answered in code rather than at a prompt, and tool calls and approvals are surfaced in the stream as they happen. |
| La Inversora | 7.0 | 6.5 | Kimi Agent SDK — 575 stars and a first-party SDK from a model vendor with no free tier: this is not a product, it is a demand-generation instrument, and it is a good one. |
| La Jefa | 7.0 | 6.3 | Kimi Agent SDK — Go, Node and Python clients and a runtime that genuinely runs headless: the rare row where the integration work lands in a pipeline instead of on a desk. |
| El Hacker | 6.8 | 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. |
