Which one would each critic pick
| Critic | Alethe | Clay Studio | Pick |
|---|---|---|---|
| El Juez | — | — | not enough reviews |
| El Amigo | 7.3 | 7.0 | Alethe — Pick it if your work is three repositories at once and you keep losing the arrangement; pick a terminal multiplexer if you already have one you love. |
| El Crítico | 6.0 | 6.5 | Clay Studio — Permission prompts can be answered by whichever teammate is looking, which means the authority to let an agent act belongs to nobody in particular. |
| El Profesor | 7.0 | 7.0 | no preference |
| La Inversora | 6.0 | 6.3 | Clay Studio — 391 stars, one maintainer and a self-hosted daemon: no seat to sell, no instance to host and no revenue line, so this is infrastructure funded by enthusiasm. |
| La Jefa | 6.5 | 6.0 | Alethe — The one thing here I would actually use is the inventory: every MCP server on the machine, grouped by which agent can see it. |
| El Hacker | 7.8 | 7.8 | no preference |
