Which one would each critic pick
| Critic | Octomind | vix | Pick |
|---|---|---|---|
| El Juez | — | — | not enough reviews |
| El Amigo | 6.5 | 6.8 | vix — Pick it if you review plans better than you review diffs; pick something quieter if a voice walkthrough sounds like a meeting you did not schedule. |
| El Crítico | 5.8 | 6.3 | vix — The agent reads and edits minified code through a virtual filesystem, so every change has to be mapped back to the real file, and that mapping can fail. |
| El Profesor | 6.5 | 6.3 | Octomind — Roles, guardrails and budgets are declared alongside the model rather than expressed in code, which makes the constraints on a run inspectable before it starts. |
| La Inversora | 5.3 | 6.0 | vix — Five distinct product ideas in one repository with 274 stars is more surface than a small team can defend for long. |
| La Jefa | 6.3 | 5.5 | Octomind — It reads a task from standard input for pipelines and scripts, which makes it the rare agent here that can be a measurable build stage. |
| El Hacker | 7.3 | 7.3 | no preference |
