Which one would each critic pick
| Critic | II-Agent | Background Agents (Open-Inspect) | Pick |
|---|---|---|---|
| El Juez | — | — | not enough reviews |
| El Amigo | 6.5 | 6.8 | Background Agents (Open-Inspect) — Pick Open-Inspect if your backlog is full of well-specified tickets; pick an interactive agent if the work needs a conversation before anyone knows what to build. |
| El Crítico | 5.8 | 6.0 | Background Agents (Open-Inspect) — It is documented as designed for single-tenant deployment inside one trusted organisation, and it can also be started by inbound webhooks and third-party alerts. |
| El Profesor | 6.5 | 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 | 6.3 | 6.3 | no preference |
| La Jefa | 5.5 | 5.3 | II-Agent — Zero per seat and a Docker Compose deployment my platform team can run, but nothing here executes unattended, so it never becomes part of a pipeline. |
| El Hacker | 7.8 | 7.3 | II-Agent — Apache-2.0, my keys, and the model config takes Vertex, Azure or a self-hosted endpoint, so inference can stay on hardware I picked. |
