Which one would each critic pick
| Critic | Jules | Background Agents (Open-Inspect) | Pick |
|---|---|---|---|
| El Juez | — | — | not enough reviews |
| El Amigo | 6.8 | 6.8 | no preference |
| El Crítico | 6.3 | 6.0 | Jules — Jules runs your repo in a VM you cannot inspect on a model you cannot choose, and the failure mode is a pull request built on an environment that never installed correctly. |
| El Profesor | 6.3 | 7.0 | Background Agents (Open-Inspect) — Pull requests carry commit attribution back to the person who prompted the run, which preserves provenance through the artefact rather than only in a log. |
| La Inversora | 6.0 | 6.3 | Background Agents (Open-Inspect) — 2,724 stars for an open reconstruction of a company's internal tool, permissively licensed, with no entity and nothing that converts that attention into revenue. |
| La Jefa | 4.8 | 5.3 | Background Agents (Open-Inspect) — No licence cost for sixty engineers, and two of the four model options are documented through consumer subscriptions, which is not a thing procurement can put on a contract. |
| El Hacker | 4.3 | 7.3 | Background Agents (Open-Inspect) — MIT and self-hosted end to end, with agents working inside full environments that carry the language runtimes, version control and an editor, and no protocol client anywhere. |
