Which one would each critic pick
| Critic | CoStrict | Notebook Intelligence | Pick |
|---|---|---|---|
| El Juez | — | — | not enough reviews |
| El Amigo | 7.0 | 7.3 | Notebook Intelligence — Pick it if your work is notebooks and you want the agent to run them, not just write them; pick a general editor agent if notebooks are incidental. |
| El Crítico | 6.0 | 6.5 | Notebook Intelligence — The command tool is documented as arbitrary code execution as the user, which is honest and is also the whole risk on a machine with anything on it. |
| El Profesor | 6.3 | 7.0 | Notebook Intelligence — Rulesets are read from a directory and injected into the system prompt, which makes the instruction layer a versioned artefact rather than a hidden default. |
| La Inversora | 7.8 | 6.5 | CoStrict — A network-security vendor giving away a coding assistant is running a channel, not a charity, and 4,401 stars is a lead list rather than a revenue line. |
| La Jefa | 6.8 | 6.0 | CoStrict — Zero licence cost across sixty desks and it deploys inside our own network, which answers the security questionnaire. It does not answer identity or audit. |
| El Hacker | 7.5 | 8.0 | Notebook Intelligence — GPL-3.0, Ollama as a first-class adapter, and a mode that shells out to the Claude Code CLI so its tools, skills and MCP servers arrive inside JupyterLab. |
