Which one would each critic pick
| Critic | Lemon | UniHarness | Pick |
|---|---|---|---|
| El Juez | — | — | not enough reviews |
| El Amigo | 6.8 | 6.3 | Lemon — Pick it if you want an assistant you message from your phone the way you message a colleague; pick a terminal agent if the work never leaves the repository. |
| El Crítico | 5.5 | 5.8 | UniHarness — One of the three supported targets is the local machine itself, which means the most convenient configuration is also the one with the boundary switched off. |
| El Profesor | 6.0 | 7.3 | UniHarness — A protocol separates the runtime from the machine it drives, and the runtime's keys, configuration and source are kept outside what the agent can read. |
| La Inversora | 5.3 | 5.3 | no preference |
| La Jefa | 5.0 | 5.3 | UniHarness — Free across sixty engineers and able to run unattended, but the confined remote target is a third-party service, which is a supplier my security review has to process. |
| El Hacker | 8.0 | 6.8 | Lemon — MIT, twenty-seven providers plus my own local endpoints, and it speaks the tool protocol in both directions, so it consumes my servers and becomes one. |
Picks are derived from each critic's own scores. Humans vote on matchups on the duels page.
