“Renamed from Claude Flow to Ruflo, which the author says stands for Rust, flow states and inevitability; one of those is a language.”

Which one would each critic pick
| Critic | OpenFang | Ruflo | Pick |
|---|---|---|---|
| El Juez | — | — | not enough reviews |
| El Amigo | 5.5 | 6.0 | Ruflo — Pick Ruflo if you already live in Claude Code and want a hundred specialised agents behind one MCP command; pick oh-my-claudecode if you want a pipeline you can explain. |
| El Crítico | 4.8 | 4.8 | no preference |
| El Profesor | 5.3 | 4.8 | OpenFang — The unit of work bundles a manifest, a multi-phase system prompt and a skill file, so planning structure is authored as data rather than emerging from a single instruction. |
| La Inversora | 5.3 | 4.8 | OpenFang — Eighteen thousand stars since February 2026 and no price of any kind, with twenty-six providers and forty channels standing in for a moat that is really an integration list. |
| La Jefa | 4.0 | 4.0 | no preference |
| El Hacker | 7.3 | 7.3 | no preference |
