Which one would each critic pick
| Critic | Atlas | OneCLI | Pick |
|---|---|---|---|
| El Juez | — | — | not enough reviews |
| El Amigo | 7.5 | 6.0 | Atlas — Atlas is for you if you want to orchestrate multiple agents and trace their work back to commits, but you must be comfortable with its all-in-one editor approach. |
| El Crítico | 6.0 | 5.8 | Atlas — Atlas executes agents without a sandbox, making it a security risk for any codebase that is not disposable. |
| El Profesor | 5.5 | 7.0 | OneCLI — Credentials are injected at the boundary rather than handed to the agent, so exfiltration is prevented structurally instead of being discouraged by instructions. |
| La Inversora | 5.8 | 5.8 | no preference |
| La Jefa | 5.5 | 6.8 | OneCLI — Agents are provisioned from our own identity provider, which is the sentence that usually takes three meetings, and nothing here runs unattended. |
| El Hacker | 7.5 | 6.3 | Atlas — Atlas is what agent source control should be: MIT-licensed, runs local models, and works fully offline. It's a solid harness for running multiple agents against one codebase. |
