“The README insists it is an assistant and not an approval system, which is the sentence you write after watching somebody use it as one.”

Which one would each critic pick
| Critic | AsyncReview | oss-pr-reviewer | Pick |
|---|---|---|---|
| El Juez | — | — | not enough reviews |
| El Amigo | 6.0 | 6.5 | oss-pr-reviewer — Pick this if you maintain a repository where the pull requests arrive faster than you read them; pick a hosted review bot if you want comments to land on the pull request itself. |
| El Crítico | 5.8 | 5.8 | no preference |
| El Profesor | 6.5 | 7.0 | oss-pr-reviewer — Responses are validated with a schema, findings are deduplicated and severity-filtered, and a truncated file list is marked explicitly incomplete with skipped files listed by reason. |
| La Inversora | 5.3 | 5.5 | oss-pr-reviewer — 112 stars, one author, permissive licence and no commercial layer anywhere. This is a utility somebody wrote for their own queue and published, which is the most common shape here. |
| La Jefa | 5.5 | 6.0 | oss-pr-reviewer — It emits JSON for a pipeline and costs nothing across sixty engineers, which makes it the rare thing on this board I can wire into a build and actually measure. |
| El Hacker | 6.3 | 5.3 | AsyncReview — MIT and it runs straight from npx with no install, but exactly one model provider is documented, so there is no substitution and no routing. |
