Which one would each critic pick
| Critic | Agentara | harness9 | Pick |
|---|---|---|---|
| El Juez | — | — | not enough reviews |
| El Amigo | 6.3 | 6.3 | no preference |
| El Crítico | 5.5 | 5.8 | harness9 — Tools run inside a container, but the shell escape prefix and the stored state do not, so the isolation covers the tidy half of what an agent does. |
| El Profesor | 6.3 | 5.5 | Agentara — Sessions persist as JSONL carrying the full message history, which makes a run reconstructible after the fact; the reasoning loop belongs to the delegated CLI. |
| La Inversora | 5.5 | 4.5 | Agentara — An MIT badge in the README with no LICENSE file in the repository is not a licence, and 504 stars around a single maintainer is not a company. |
| La Jefa | 4.8 | 5.5 | harness9 — Every plan, tool result and record stays on the developer's own machine, which answers the data residency question and creates the discovery problem. |
| El Hacker | 6.5 | 6.5 | no preference |
