Which one would each critic pick
| Critic | Vicoa | harness | Pick |
|---|---|---|---|
| El Juez | — | — | not enough reviews |
| El Amigo | 6.5 | 6.0 | Vicoa — Vicoa is for developers who want to run multiple agents in parallel on the same codebase and steer them from anywhere. |
| El Crítico | 6.0 | 4.5 | Vicoa — Vicoa orchestrates agents but lacks a sandbox, making it a powerful but risky command center for experienced users. |
| El Profesor | 5.3 | 6.3 | harness — The core handles only discovery, hook dispatch and the loop; providers, serialisation and prompt loading are all plugins, which makes the boundary between mechanism and policy explicit. |
| La Inversora | 6.0 | 5.5 | Vicoa — Vicoa is a useful orchestrator for developers managing multiple agents, but its BYOK model and lack of a clear revenue stream make it a likely acquisition target. |
| La Jefa | 3.5 | 4.3 | harness — Free across sixty engineers and it runs unattended, but the approval gates and the cost tracking are both plugins, which means both are optional. |
| El Hacker | 6.0 | 7.3 | harness — MIT, Homebrew or the AUR, and the entire dependency list is bash, jq and curl, with plugins in whatever language I feel like writing them in. |
