Which one would each critic pick
| Critic | OneCLI | OpenDesign | Pick |
|---|---|---|---|
| El Juez | — | — | not enough reviews |
| El Amigo | 6.0 | 6.8 | OpenDesign — Pick this if you need a design-focused harness for your existing agents and want to produce visual artifacts like prototypes and decks locally. |
| El Crítico | 5.8 | 6.0 | OpenDesign — It claims full terminal execution power for agents but provides no documented sandbox, a dealbreaker for running untrusted code. |
| El Profesor | 7.0 | 4.5 | OneCLI — Credentials are injected at the boundary rather than handed to the agent, so exfiltration is prevented structurally instead of being discouraged by instructions. |
| La Inversora | 5.8 | 7.3 | OpenDesign — A strong open-core play with impressive adoption, but its position as a meta-layer makes it a prime acquisition target for a major model provider seeking distribution. |
| La Jefa | 6.8 | 4.5 | OneCLI — Agents are provisioned from our own identity provider, which is the sentence that usually takes three meetings, and nothing here runs unattended. |
| El Hacker | 6.3 | 8.0 | OpenDesign — OpenDesign is a proper local-first design tool that hooks into existing agents, but its value depends on you bringing a capable agent and model to the party. |
