Which one would each critic pick
| Critic | LangGraph4j | Zypher Agent | Pick |
|---|---|---|---|
| El Juez | — | — | not enough reviews |
| El Amigo | 7.0 | 6.8 | LangGraph4j — Pick it if your platform is the JVM and leaving it is not on the table; pick the Python original if nothing is stopping you from choosing a language. |
| El Crítico | 6.5 | 6.5 | no preference |
| El Profesor | 7.5 | 7.5 | no preference |
| La Inversora | 6.5 | 6.5 | no preference |
| La Jefa | 6.3 | 6.5 | Zypher Agent — It ships a terminal tool, so whatever we embed it in inherits the ability to run commands on the host it lands on. |
| El Hacker | 7.3 | 6.8 | LangGraph4j — MIT, published to Maven Central with a bill of materials so versions line up, and the model layer is delegated, so a local endpoint works without this library knowing about it. |
