“It ships a skill that lets a coding agent drive Rove itself, so the agents can now start each other and nobody has to be present.”

Which one would each critic pick
| Critic | Babysitter | Rove | Pick |
|---|---|---|---|
| El Juez | — | — | not enough reviews |
| El Amigo | 6.0 | 6.8 | Rove — Pick Rove if you want three agents working while your laptop is shut; pick a single terminal agent if you have never actually wanted three things happening at once. |
| El Crítico | 5.8 | 5.5 | Babysitter — Twelve harnesses are listed and only two are described as fully worked, with three more marked experimental, so harness-agnostic is a roadmap rather than a state. |
| El Profesor | 6.3 | 6.5 | Rove — The unit of work is a worktree with its own branch, which makes the concurrency model a property of the version control system rather than of the application. |
| La Inversora | 5.8 | 5.8 | no preference |
| La Jefa | 6.0 | 4.8 | Babysitter — Free for sixty engineers, and every decision is written to an immutable journal, which is the audit artefact I cannot get from a coding agent any other way. |
| El Hacker | 6.8 | 7.5 | Rove — MIT, and any CLI I register becomes a task runner, so it is not limited to the four names in the description. There is no MCP client, and it does not need one. |
