Which one would each critic pick
| Critic | oh-my-openagent | Yao Agents | Pick |
|---|---|---|---|
| El Juez | — | — | not enough reviews |
| El Amigo | 6.5 | 5.8 | oh-my-openagent — Pick oh-my-openagent if you already run OpenCode or Codex CLI and want a planner, a deep worker and an oracle wired in; pick oh-my-claudecode if your agent is Claude Code. |
| El Crítico | 5.5 | 5.8 | Yao Agents — This is an agent management platform, not an agent execution environment. |
| El Profesor | 5.5 | 2.0 | oh-my-openagent — Requests are routed by category, quick, deep, ultrabrain and visual-engineering, to different agents and models; five or more background specialists run with isolated context under 54-plus hooks. |
| La Inversora | 4.8 | 5.3 | Yao Agents — This is a classic venture-subsidized free tier play; use it for personal tasks, but don't build a business on a platform with no visible revenue model. |
| La Jefa | 5.0 | 4.8 | oh-my-openagent — Bundled MCP servers send web searches to Exa and code searches to Grep.app from every engineer's terminal, with no admin, no SSO and a bun prerequisite; not yet. |
| El Hacker | 5.8 | 3.8 | oh-my-openagent — Sustainable Use License 1.0, free for personal and internal use and not for resale, config in .omo/omo.jsonc walked upward from the project, six hosted providers and no local one. |
