Which one would each critic pick
| Critic | AgentOS | Sculptor | Pick |
|---|---|---|---|
| El Juez | — | — | not enough reviews |
| El Amigo | 5.5 | 6.3 | Sculptor — Pick it if you want three agents attempting a task on three branches and a pull request at the end; pick Claude Squad if you would rather that happened in a terminal. |
| El Crítico | 5.3 | 5.3 | no preference |
| El Profesor | 6.3 | 6.5 | Sculptor — It drives the wrapped agent as a streaming-JSON process with the control protocol enabled and substitutes its own ask-user and plan tools, which is interception done properly. |
| La Inversora | 5.0 | 5.3 | Sculptor — This is a research lab's artefact rather than a company's product: no pricing page, a preview label, and a couple of hundred stars after a year. |
| La Jefa | 5.0 | 4.8 | AgentOS — Zero per seat across sixty desks, a signed receipt for every action, and no console, no SSO and nothing that runs unattended. |
| El Hacker | 6.0 | 5.8 | AgentOS — Apache-2.0 and my own key is the good half; MCP is absent on both ends and the weights have to live on somebody else's endpoint. |
