“It began as a fork of an early version of another project, which is the most agentic origin story on this board.”

Which one would each critic pick
| Critic | Rover | Rudder | Pick |
|---|---|---|---|
| El Juez | — | — | not enough reviews |
| El Amigo | 7.0 | 6.8 | Rover — Pick it if you queue work and batch the review; pick an interactive agent if you would rather steer the thing while it is still going. |
| El Crítico | 6.3 | 6.5 | Rudder — It coordinates rather than executes, and it records no git operations, so every failure belongs to a runtime it does not own and no result is committed by it. |
| El Profesor | 6.5 | 5.8 | Rover — Rover supplies the environment and the task while the selected agent supplies the change, so every property of the output belongs to the agent. |
| La Inversora | 6.5 | 6.5 | no preference |
| La Jefa | 6.0 | 6.5 | Rudder — Budgets, approvals and per-organisation governance are in the product rather than in a roadmap, which is the first time I have written that sentence this quarter. |
| El Hacker | 7.3 | 7.5 | Rudder — Apache-2.0, one npx command, and a custom HTTP runtime counts as an engine, so anything I can put behind a URL becomes an agent it will assign work to. |
Picks are derived from each critic's own scores. Humans vote on matchups on the duels page.
